What is the Origin of Female Perimenopause Hormones?

The term is descriptive, combining 'female' and 'hormones' with 'perimenopause,' derived from the Greek peri meaning 'around' and menopausis meaning 'cessation of menstruation.' It specifically defines the hormonal milieu of the years preceding the final menstrual period. This classification is rooted in reproductive endocrinology, marking a natural biological transition.

What is the Mechanism of Female Perimenopause Hormones?

The decline in ovarian follicle reserve leads to inconsistent ovulation and reduced production of estradiol and progesterone. The pituitary gland attempts to compensate for this reduced feedback by increasing the secretion of FSH, often resulting in wide hormonal fluctuations. These erratic signals impact target tissues throughout the body, manifesting as the characteristic symptoms associated with this critical life stage.

Female Perimenopause Hormones

Meaning

The key endocrine signaling molecules, primarily estradiol, progesterone, and follicle-stimulating hormone (FSH), whose fluctuating and declining levels characterize the transitional period leading up to menopause. This phase involves significant shifts in ovarian function, leading to changes in menstrual cycle regularity and the onset of vasomotor and psychological symptoms. Clinically, monitoring these hormonal dynamics is essential for managing perimenopausal health.
