Study Notes
Female Menstrual Cycle: Physiology and Pharmacology
- The female menstrual cycle involves the uterus, cervix, endometrium, myometrium, uterine tubes, ovaries, vagina, and oogenesis.
- Oogenesis occurs within follicles, which consist of an oocyte surrounded by follicular cells.
- Primordial follicles are formed during prenatal development, but no new ones appear as the female ages.
- Follicular development involves primordial follicles, primary follicles, graffian follicles, and corpus luteum.
- Each month, multiple follicles begin maturation, but only one becomes dominant, while the others die through atresia.
- The dominant follicle produces estrogen, which inhibits FSH release and causes the endometrium to thicken.
- The menstrual cycle begins with the bleeding phase, characterized by lower levels of estrogen and progesterone.
- The follicular phase is marked by the development of follicles stimulated by FSH and LH release.
- The dominant follicle produces estrogen, leading to positive feedback on gonadotropin release and thickening of the endometrium.
- The mid-cycle surge of LH and FSH induces ovulation, with the ruptured follicle becoming a corpus luteum.
- The luteal phase is characterized by the secretion of estrogen, progesterone, and inhibin by the corpus luteum, supporting the endometrium.
- Unless pregnancy occurs, the corpus luteum degenerates, leading to low levels of estrogen, progesterone, and inhibin, and the shedding of the endometrium.
