Menstruation regulation

Menstruation regulation is a complex physiological process governed by the hypothalamic-pituitary-ovarian (HPO) axis, rather than a single molecular target. It involves the rhythmic secretion of gonadotropin-releasing hormone (GnRH), which stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to coordinate follicular development, ovulation, and endometrial changes (StatPearls, 2023). Key molecular players in this process include the estrogen receptors (ERα and ERβ) and progesterone receptors (PR-A and PR-B), which respond to fluctuating levels of steroid hormones (NIH, 2022). Pharmacological intervention in menstruation regulation typically targets these receptors or the GnRH receptor to treat conditions such as dysmenorrhea, menorrhagia, or to provide contraception (PubMed, 2021). Because it encompasses a network of signaling pathways and multiple distinct proteins, 'Menstruation regulation' is classified as a biological process or therapeutic indication rather than a discrete, druggable molecular target. Dysregulation of this process can lead to various clinical conditions, including polycystic ovary syndrome (PCOS) and endometriosis. Therapeutic strategies often aim to restore hormonal balance or suppress the cycle entirely depending on the clinical need. Monitoring of this process is typically done through serum hormone levels and ultrasound imaging of the reproductive organs.

Regulation is achieved through the exogenous administration of estrogen and progesterone derivatives which provide negative feedback to the hypothalamus and pituitary, or through GnRH receptor modulation to suppress the HPO axis.
