Fundamentals
Your body is a finely tuned orchestra of communication, and hormones are its messengers, carrying vital instructions to every cell and system. When you experience shifts in your well-being, from your energy levels and mood to your physical strength and libido, it is often a sign that this internal communication network is undergoing a change.
For women, the conversation around hormones has historically centered on estrogen and progesterone. Yet, there is another significant voice in this choir, one that is essential for your vitality and function ∞ testosterone. Understanding its role is a pivotal step in reclaiming a sense of wholeness and command over your own biological narrative.
The journey to understanding your own body can feel like navigating a complex landscape without a map. You may have noticed subtle or significant changes, a feeling that something is ‘off’ without a clear explanation. These experiences are valid and deserve to be met with clear, evidence-based knowledge.
This exploration of testosterone and its relationship with your endometrial health Meaning ∞ Endometrial health refers to the optimal physiological state of the endometrium, the inner lining of the uterus, characterized by its structural integrity, functional capacity, and appropriate responsiveness to hormonal signals throughout the menstrual cycle. is designed to provide you with that map. It is a journey into the science of your own body, a path toward understanding the intricate connections that govern your well-being. The goal is to empower you with the knowledge to have informed conversations with your healthcare provider and to make decisions that align with your personal health goals.
The Endocrine System a Symphony of Signals
Your endocrine system is a network of glands that produce and release hormones. Think of it as a sophisticated postal service, where hormones are letters carrying specific instructions to different parts of your body. These instructions regulate a vast array of functions, including your metabolism, growth and development, sleep, mood, and reproductive health.
The system operates on a delicate balance, with glands communicating with each other through feedback loops to maintain a state of equilibrium, or homeostasis. When one hormone level changes, it can have a cascading effect on others, which is why a holistic view of hormonal health is so important.
The primary glands in the female endocrine system include the pituitary gland, the thyroid gland, the adrenal glands, and the ovaries. The ovaries are the main producers of estrogen and progesterone, the two hormones most commonly associated with the menstrual cycle Meaning ∞ The Menstrual Cycle is a recurring physiological process in females of reproductive age, typically 21 to 35 days. and menopause.
However, the ovaries and adrenal glands also produce testosterone, an androgen that plays a crucial role in female physiology. This androgen is not just a ‘male’ hormone; it is a vital component of a woman’s hormonal makeup, contributing to bone density, muscle mass, cognitive function, and sexual health.
Testosterone’s Role in the Female Body
For many years, testosterone’s presence in women was largely overlooked in clinical practice. Today, we have a much deeper appreciation for its significance. In women, testosterone is produced in smaller amounts than in men, but its impact is profound. It contributes to the maintenance of lean muscle mass, which is essential for metabolic health and strength.
It supports bone density, helping to protect against osteoporosis, a condition that becomes more common after menopause. Testosterone also plays a role in cognitive function, including memory and spatial awareness. Furthermore, it is a key driver of libido and sexual satisfaction.
When testosterone levels Meaning ∞ Testosterone levels denote the quantifiable concentration of the primary male sex hormone, testosterone, within an individual’s bloodstream. decline, which can happen due to age, menopause, or certain medical conditions, women may experience a range of symptoms. These can include fatigue, a loss of muscle tone, weight gain, brain fog, and a diminished sex drive.
These symptoms can significantly impact quality of life, and recognizing their connection to testosterone deficiency is the first step toward addressing them. Hormonal optimization Meaning ∞ Hormonal Optimization is a clinical strategy for achieving physiological balance and optimal function within an individual’s endocrine system, extending beyond mere reference range normalcy. protocols that include testosterone are designed to restore this vital hormone to its optimal physiological range, helping to alleviate these symptoms and improve overall well-being.
Understanding the intricate dance of hormones within your body is the foundation of proactive wellness and longevity science.
What Is the Endometrium and Why Is Its Health Important?
The endometrium is the inner lining of the uterus. It is a dynamic tissue that changes throughout the menstrual cycle in response to hormonal fluctuations. During the first half of the cycle, estrogen stimulates the endometrium to thicken and grow, preparing it for a potential pregnancy.
After ovulation, progesterone levels rise, and this hormone helps to stabilize the endometrium, making it receptive to a fertilized egg. If pregnancy does not occur, estrogen and progesterone Meaning ∞ Estrogen and progesterone are vital steroid hormones, primarily synthesized by the ovaries in females, with contributions from adrenal glands, fat tissue, and the placenta. levels fall, causing the endometrium to shed, which results in menstruation.
The health of the endometrium is a critical aspect of female reproductive health. A healthy endometrium is essential for fertility. Problems with the endometrium can lead to issues such as heavy or irregular bleeding, infertility, and pelvic pain. One of the primary concerns regarding endometrial health is the risk of endometrial hyperplasia, a condition where the endometrium becomes too thick.
Endometrial hyperplasia can sometimes lead to endometrial cancer, which is why it is so important to maintain a healthy balance of hormones that regulate endometrial growth.
The concern about testosterone therapy Meaning ∞ A medical intervention involves the exogenous administration of testosterone to individuals diagnosed with clinically significant testosterone deficiency, also known as hypogonadism. and endometrial safety stems from the fact that testosterone can be converted into estrogen in the body through a process called aromatization. An increase in estrogen levels, particularly without the counterbalancing effect of progesterone, can stimulate the growth of the endometrium, potentially increasing the risk of hyperplasia.
This is why a careful and personalized approach to testosterone therapy is so important for women who have a uterus. The goal is to optimize testosterone levels while maintaining endometrial safety. This is achieved through careful monitoring and, when necessary, the use of progesterone to protect the uterine lining.
Intermediate
Building upon the foundational knowledge of testosterone’s role in the female body and the importance of endometrial health, we now turn our attention to the clinical application of testosterone therapy. For women experiencing the symptoms of testosterone deficiency, hormonal optimization can be a transformative experience.
However, the decision to begin testosterone therapy is one that should be made in partnership with a knowledgeable healthcare provider who can tailor a protocol to your specific needs and physiology. A key aspect of this personalized approach is the choice of delivery method, as different methods can have varying effects on hormone levels Meaning ∞ Hormone levels refer to the quantifiable concentrations of specific hormones circulating within the body’s biological fluids, primarily blood, reflecting the dynamic output of endocrine glands and tissues responsible for their synthesis and secretion. and, consequently, on endometrial safety.
The primary objective of any testosterone therapy protocol is to restore testosterone levels to a healthy physiological range, thereby alleviating symptoms and improving quality of life. At the same time, a well-designed protocol must prioritize safety, and for women with a uterus, this means carefully considering the potential impact on the endometrium.
The science behind this is clear ∞ while testosterone itself does not directly stimulate endometrial growth, its conversion to estrogen can. Therefore, the conversation about endometrial safety Meaning ∞ Endometrial safety refers to the clinical objective of protecting the uterine lining from excessive cellular proliferation, especially when influenced by hormonal interventions. in the context of testosterone therapy is really a conversation about managing estrogen levels and ensuring the endometrium is adequately protected.
Comparing Testosterone Delivery Methods
There are several ways to administer testosterone, each with its own set of advantages and disadvantages. The choice of delivery method depends on a variety of factors, including patient preference, lifestyle, and the desired pharmacokinetic profile. The goal is to achieve stable testosterone levels that mimic the body’s natural production as closely as possible, while minimizing peaks and troughs that can lead to side effects. Let’s explore some of the most common delivery methods for women.
Intramuscular and Subcutaneous Injections
Testosterone cypionate is a long-acting ester of testosterone that is typically administered via intramuscular or subcutaneous injection. For women, the doses are much lower than those used for men, often in the range of 10-20 units (0.1-0.2ml) per week. Injections can be a very effective way to raise testosterone levels, and they offer a high degree of control over dosing.
The weekly administration schedule helps to maintain relatively stable hormone levels, which can minimize the risk of side effects. Subcutaneous injections, which are administered into the fatty tissue just under the skin, are often preferred by women as they are less painful than intramuscular injections and can be easily self-administered at home.
From an endometrial safety perspective, the key consideration with injections is the potential for aromatization. The amount of testosterone that is converted to estrogen can vary from person to person, depending on factors such as body fat percentage and genetics. For this reason, it is essential to monitor both testosterone and estrogen levels Meaning ∞ Estrogen levels denote the measured concentrations of steroid hormones, predominantly estradiol (E2), estrone (E1), and estriol (E3), circulating within an individual’s bloodstream. regularly when using injectable testosterone.
If estrogen levels become elevated, your healthcare provider may recommend the addition of an aromatase inhibitor, such as anastrozole, to block the conversion of testosterone to estrogen. For women with a uterus, the use of progesterone is also a critical component of the protocol to ensure the endometrium is protected.
Testosterone Pellets
Testosterone pellets are small, crystalline cylinders of testosterone that are inserted under the skin, usually in the hip or buttock area. The pellets slowly release testosterone over a period of three to six months, providing a steady and consistent dose of the hormone.
This can be a very convenient option for women who do not want to have to remember to administer their medication on a weekly basis. The long-acting nature of pellets also means that they can provide very stable hormone levels, which can be beneficial for both symptom relief and safety.
With pellet therapy, as with injections, monitoring of hormone levels is crucial. The dose of the pellets is individualized based on the patient’s symptoms and baseline hormone levels. After the pellets are inserted, follow-up blood tests are performed to ensure that testosterone levels are in the optimal range and that estrogen levels are not becoming elevated.
If necessary, an aromatase inhibitor can be prescribed to manage estrogen levels. Progesterone is also recommended for women with a uterus who are using testosterone pellets Meaning ∞ Testosterone pellets are small, solid dosage forms of the hormone testosterone, meticulously engineered for subcutaneous implantation, designed to deliver a consistent and prolonged release of the androgen over several months for therapeutic purposes. to provide endometrial protection.
Transdermal Creams and Gels
Transdermal testosterone creams and gels are applied directly to the skin, usually on the arms, shoulders, or abdomen. The testosterone is absorbed through the skin and enters the bloodstream. This can be a convenient and non-invasive delivery method. However, there are some potential drawbacks to consider.
The absorption of transdermal testosterone Meaning ∞ Transdermal testosterone is a pharmaceutical formulation of the male sex hormone testosterone designed for absorption through the skin into systemic circulation. can be variable, depending on factors such as skin thickness, application site, and the presence of sweat or lotions. This can make it more challenging to achieve stable hormone levels.
Another important consideration with transdermal testosterone is the risk of transference to others through skin-to-skin contact. This is a particular concern for women who have close contact with children or pregnant women. From an endometrial safety perspective, the variable absorption of transdermal testosterone can make it more difficult to manage estrogen levels.
Regular monitoring of both testosterone and estrogen is essential, and the use of progesterone is recommended for women with a uterus. Some studies have suggested that transdermal delivery Meaning ∞ Transdermal delivery involves administering therapeutic agents through the skin for systemic absorption, allowing substances to enter the bloodstream directly. may lead to higher levels of dihydrotestosterone (DHT), a potent androgen, which could have its own set of effects on the body.
Personalized hormonal optimization protocols are designed to restore biochemical balance and reclaim vitality, with a constant focus on long-term safety.
The Protective Role of Progesterone
For any woman with a uterus who is undergoing testosterone therapy, the inclusion of progesterone in the treatment protocol is of paramount importance. Progesterone is a hormone that has a powerful antiproliferative effect on the endometrium. It counteracts the growth-promoting effects of estrogen, helping to prevent the development of endometrial hyperplasia. In essence, progesterone acts as a ‘brake’ on endometrial growth, ensuring that the lining of the uterus remains thin and healthy.
The need for progesterone in the context of testosterone therapy is based on the principle of unopposed estrogen. When estrogen levels are elevated without the balancing influence of progesterone, the endometrium can be stimulated to grow excessively. Since testosterone can be converted to estrogen, any testosterone therapy protocol has the potential to increase estrogen levels.
Therefore, even if a woman is not taking estrogen replacement therapy, the use of testosterone alone can create a state of unopposed estrogen if her progesterone levels are low. This is why progesterone supplementation is a standard and essential component of care for women with a uterus who are on testosterone therapy.
Progesterone can be administered in several forms, including oral capsules, vaginal suppositories, and transdermal creams. The choice of delivery method and dose will depend on the individual’s needs and preferences. For women who are still menstruating, progesterone may be prescribed cyclically to mimic the natural menstrual cycle. For postmenopausal women, it is often taken continuously. Regular monitoring of hormone levels and endometrial health is essential to ensure that the progesterone dose is adequate to provide full protection.
Monitoring Endometrial Safety a Proactive Approach
A proactive approach to monitoring is a cornerstone of safe and effective testosterone therapy for women. This involves regular communication with your healthcare provider, as well as periodic testing to assess your hormone levels and endometrial health. The goal of monitoring is to ensure that your testosterone levels are in the optimal range for symptom relief, while also confirming that your estrogen levels are well-managed and your endometrium is protected.
The following table outlines the key components of a comprehensive monitoring plan for women on testosterone therapy:
| Monitoring Component | Frequency | Purpose |
|---|---|---|
| Baseline Hormone Panel | Before starting therapy | To establish a baseline for testosterone, estrogen, progesterone, and other relevant hormones. |
| Follow-up Hormone Panel | 4-6 weeks after starting therapy, then every 3-6 months | To assess the response to treatment, adjust dosing as needed, and monitor for any changes in hormone levels. |
| Transvaginal Ultrasound | As needed, especially if abnormal bleeding occurs | To measure the thickness of the endometrium and check for any abnormalities. |
| Endometrial Biopsy | If the transvaginal ultrasound shows significant thickening or other concerns | To obtain a tissue sample from the endometrium for histopathological analysis to rule out hyperplasia or cancer. |
In addition to these clinical assessments, it is important to pay close attention to your own body and to report any new or unusual symptoms to your healthcare provider. This includes any changes in your menstrual cycle, such as heavy or irregular bleeding, as well as any other symptoms that may be related to your hormone therapy.
By taking a proactive and collaborative approach to your health, you can ensure that you are receiving the full benefits of testosterone therapy while minimizing any potential risks.
The following list highlights some of the key considerations for endometrial safety in women undergoing testosterone therapy:
- Individualized Dosing ∞ The dose of testosterone should be carefully tailored to the individual’s needs and response to treatment.
- Progesterone Protection ∞ For women with a uterus, the use of progesterone is essential to protect the endometrium from the effects of unopposed estrogen.
- Regular Monitoring ∞ Regular monitoring of hormone levels and endometrial health is crucial to ensure the safety and effectiveness of therapy.
- Aromatase Management ∞ If estrogen levels become elevated, the use of an aromatase inhibitor may be necessary to block the conversion of testosterone to estrogen.
- Patient Education ∞ It is important for women to be well-informed about the potential risks and benefits of testosterone therapy and to be active participants in their own care.
Academic
A sophisticated understanding of endometrial safety in the context of female testosterone therapy requires a deep exploration of the molecular and cellular mechanisms at play within the uterine lining. The clinical conversation often revolves around the aromatization Meaning ∞ Aromatization is a biochemical process where the enzyme aromatase converts androgens, like testosterone and androstenedione, into estrogens, primarily estradiol and estrone. of testosterone to estradiol and the subsequent need for progesterone to mitigate the risk of endometrial hyperplasia.
While this is a critical and accurate framework, it represents a simplified view of a much more complex biological reality. A more granular analysis reveals a nuanced interplay between androgen receptors, estrogen receptors, and various signaling pathways Meaning ∞ Signaling pathways represent the ordered series of molecular events within or between cells that transmit specific information from an extracellular stimulus to an intracellular response. within the endometrial stroma and epithelium. This section will delve into the academic literature to explore these intricate interactions and to consider how different testosterone delivery methods Tailored testosterone delivery, combined with specific modulators, can preserve male fertility by mitigating HPG axis suppression. might differentially impact this delicate microenvironment.
The endometrium is a highly plastic tissue, exquisitely sensitive to the fluctuating tides of ovarian hormones. Its cyclical proliferation and differentiation are orchestrated by a complex symphony of signaling molecules, growth factors, and transcription factors. The introduction of exogenous testosterone into this system adds another layer of complexity.
To fully appreciate the implications for endometrial safety, we must move beyond a simple consideration of hormone levels and examine the direct and indirect effects of androgens on endometrial cell biology. This requires a systems-level perspective that integrates our knowledge of endocrinology, molecular biology, and pharmacology.
Androgen Receptor Signaling in the Endometrium
The human endometrium expresses androgen receptors Meaning ∞ Androgen Receptors are intracellular proteins that bind specifically to androgens like testosterone and dihydrotestosterone, acting as ligand-activated transcription factors. (AR) in both the epithelial and stromal compartments. The presence of these receptors indicates that androgens can exert direct effects on endometrial cells, independent of their conversion to estrogens. The binding of testosterone or its more potent metabolite, dihydrotestosterone (DHT), to the AR initiates a cascade of events that can modulate gene expression and cellular function.
The precise effects of AR activation in the endometrium are still an area of active research, but several key findings have emerged.
In vitro studies using human endometrial cell lines have shown that androgens can have antiproliferative effects. For example, one study demonstrated that testosterone could inhibit the growth of endometrial cancer cells by inducing apoptosis, or programmed cell death. Another study found that androgens could downregulate the expression of certain genes involved in cell cycle progression.
These findings suggest that direct AR signaling may have a protective role in the endometrium, counteracting the proliferative drive of estrogens. This is consistent with the clinical observation that some women on combined estrogen-testosterone therapy have a lower incidence of endometrial hyperplasia Meaning ∞ Endometrial hyperplasia refers to a condition characterized by an excessive proliferation of the endometrial glands, the lining of the uterus. compared to those on estrogen alone.
The balance between the proliferative effects of estrogen and the potential antiproliferative effects of androgens is likely a key determinant of endometrial health. This balance can be influenced by a variety of factors, including the relative expression levels of estrogen receptors Meaning ∞ Estrogen Receptors are specialized protein molecules within cells, serving as primary binding sites for estrogen hormones. (ER) and androgen receptors, the local concentration of different hormones, and the activity of enzymes such as aromatase and 5-alpha reductase (which converts testosterone to DHT).
The complexity of these interactions underscores the importance of a personalized approach to hormone therapy, as the optimal balance of hormones will vary from person to person.
The Interplay between Androgen and Estrogen Receptor Pathways
The signaling pathways of the androgen receptor Meaning ∞ The Androgen Receptor (AR) is a specialized intracellular protein that binds to androgens, steroid hormones like testosterone and dihydrotestosterone (DHT). and the estrogen receptor are not independent entities; they engage in a complex crosstalk that can further modulate the endometrial response to hormones. This crosstalk can occur at multiple levels, from the regulation of receptor expression to the competition for common co-regulatory proteins.
For example, some studies have shown that androgens can downregulate the expression of estrogen receptors in endometrial cells, which would be expected to reduce the sensitivity of the tissue to estrogenic stimulation.
Another level of interaction involves the competition for binding to specific DNA sequences known as hormone response elements (HREs). Both AR and ER belong to the nuclear receptor superfamily and bind to similar HREs on target genes.
This means that they can compete for access to these regulatory regions, with the outcome depending on the relative abundance and activity of the two receptors. In a scenario where AR is highly activated, it could potentially displace ER from its binding sites, thereby inhibiting the transcription of estrogen-responsive genes.
The following table summarizes some of the potential mechanisms of crosstalk between androgen and estrogen receptor Meaning ∞ Estrogen receptors are intracellular proteins activated by the hormone estrogen, serving as crucial mediators of its biological actions. signaling in the endometrium:
| Mechanism | Description | Potential Impact on Endometrial Health |
|---|---|---|
| Receptor Downregulation | Androgens can decrease the expression of estrogen receptors in endometrial cells. | Reduced sensitivity to estrogenic stimulation, potentially mitigating the risk of hyperplasia. |
| Competition for HREs | Androgen receptors and estrogen receptors can compete for binding to the same DNA response elements. | Inhibition of estrogen-driven gene expression, leading to an antiproliferative effect. |
| Co-regulator Sequestration | Activated androgen receptors can sequester co-regulatory proteins that are also required for estrogen receptor function. | Indirect inhibition of estrogen receptor activity, further contributing to an antiproliferative state. |
| Modulation of Signaling Pathways | Androgen receptor signaling can intersect with other signaling pathways, such as the PI3K/Akt pathway, which can influence cell growth and survival. | Complex effects on cell fate that can be either pro- or anti-proliferative depending on the cellular context. |
How Might Delivery Methods Influence These Molecular Mechanisms?
The choice of testosterone delivery Meaning ∞ Testosterone Delivery refers to the various methods and routes employed to administer exogenous testosterone into the human body, primarily for therapeutic purposes such as hormone replacement therapy. method can have a significant impact on the pharmacokinetic profile of the hormone, which in turn can influence the molecular events within the endometrium. Different delivery methods result in different patterns of testosterone release, absorption, and metabolism. These differences can affect not only the circulating levels of testosterone and its metabolites but also the local hormonal milieu within the endometrium.
Steady-State Vs. Pulsatile Delivery
Testosterone pellets, which provide a slow and steady release of the hormone over several months, are designed to create a stable, steady-state concentration of testosterone in the bloodstream. This can be contrasted with intramuscular injections, which can result in more pronounced peaks and troughs in hormone levels.
From a molecular perspective, a stable hormonal environment may be more conducive to maintaining a balanced state of AR and ER signaling in the endometrium. The pulsatile delivery associated with injections could potentially lead to more dynamic and less predictable changes in receptor activation and gene expression.
For example, a sudden spike in testosterone levels after an injection could lead to a rapid increase in aromatization and a transient surge in estrogen levels. This could temporarily shift the balance in favor of estrogenic stimulation of the endometrium.
In contrast, the stable levels achieved with pellets may allow for a more consistent and sustained activation of the antiproliferative AR pathways, providing a more reliable counterbalance to any estrogenic effects. This is a theoretical consideration that warrants further investigation in clinical studies.
The Role of First-Pass Metabolism
Transdermal delivery of testosterone avoids first-pass metabolism in the liver, which can have implications for the overall metabolic profile of the hormone. When testosterone is administered orally, it is subject to extensive metabolism in the liver before it reaches the systemic circulation.
This can lead to the production of a variety of metabolites, some of which may have their own biological activity. By bypassing the liver, transdermal delivery can result in a different ratio of testosterone to its metabolites compared to other delivery methods.
One important consideration is the conversion of testosterone to DHT by the enzyme 5-alpha reductase. This enzyme is present in the skin, so transdermal delivery can lead to relatively high levels of DHT. DHT is a potent androgen that binds to the AR with high affinity.
If DHT has a more pronounced antiproliferative effect on the endometrium than testosterone itself, then transdermal delivery could potentially offer an advantage in terms of endometrial safety. However, the precise effects of DHT on the endometrium are not fully understood, and more research is needed to clarify its role.
The future of hormonal optimization lies in a deeper understanding of the molecular pharmacology of different delivery systems and their impact on target tissues.
Future Directions in Research
Our understanding of the effects of testosterone on the endometrium has evolved significantly in recent years, but there are still many unanswered questions. The long-term safety of testosterone therapy in women, particularly with respect to the endometrium, is an area that requires further investigation. Large, well-designed clinical trials are needed to compare the effects of different testosterone delivery Tailored testosterone delivery, combined with specific modulators, can preserve male fertility by mitigating HPG axis suppression. methods on endometrial histology and to identify the optimal strategies for monitoring and managing endometrial health.
Future research should also focus on elucidating the molecular mechanisms underlying the effects of androgens on the endometrium. This could involve the use of advanced techniques such as single-cell RNA sequencing to characterize the gene expression Meaning ∞ Gene expression defines the fundamental biological process where genetic information is converted into a functional product, typically a protein or functional RNA. profiles of different cell types within the endometrium in response to hormone treatment.
A deeper understanding of the crosstalk between AR and ER signaling could lead to the development of more targeted therapies that can maximize the benefits of testosterone while minimizing any potential risks.
The following list outlines some of the key areas for future research:
- Long-term safety studies ∞ Prospective, randomized controlled trials are needed to evaluate the long-term effects of different testosterone delivery methods on endometrial health.
- Molecular mechanism studies ∞ Further research is needed to elucidate the molecular mechanisms by which androgens modulate endometrial cell function.
- Biomarker development ∞ The identification of reliable biomarkers for assessing endometrial health in women on testosterone therapy would be a valuable clinical tool.
- Personalized medicine ∞ Research into the genetic and other factors that influence an individual’s response to testosterone therapy could help to personalize treatment and optimize outcomes.
In conclusion, the issue of endometrial safety in women undergoing testosterone therapy is a complex one that involves a delicate balance of hormonal and molecular signals. While the conversion of testosterone to estrogen is a key consideration, it is also important to recognize the direct effects of androgens on the endometrium, which may be protective.
The choice of delivery method can influence the pharmacokinetic and pharmacodynamic properties of testosterone, which in turn can impact the endometrial response. A deeper understanding of these complex interactions will be essential for the continued development of safe and effective testosterone therapy protocols for women.
