What is the Origin of Reproductive Markers?

This clinical term is rooted in reproductive endocrinology, where the need to quantify the biological health and potential of the gonadal axis led to the development of specific assays and diagnostic criteria. The concept has evolved with advanced laboratory techniques, allowing for increasingly precise measurement of these key indicators.

What is the Mechanism of Reproductive Markers?

Reproductive markers function as direct or indirect outputs of the hypothalamic-pituitary-gonadal (HPG) axis. For example, AMH is secreted by ovarian follicles and directly correlates with ovarian reserve, while FSH levels reflect the pituitary's attempt to stimulate the gonads, often rising as gonadal function declines. Clinically, measuring these markers allows the physician to map the feedback loops and secretory capacity of the endocrine system, providing a functional assessment of fertility and hormonal balance.

Reproductive Markers

Meaning

A collection of measurable biochemical substances, hormones, and physiological indicators used in clinical endocrinology to assess the function, capacity, and status of the male and female reproductive systems. These markers include key hormones such as Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), Anti-Müllerian Hormone (AMH), and sex steroids, as well as clinical indicators like semen analysis or ovarian follicle count. They provide objective data for diagnosing infertility, monitoring hormonal treatments, and evaluating the transition through perimenopause.
