MEDICAL PHYSIOLOGY

Detailed explanation-1: -The hypothalamus secretes GnRH in a pulsatile fashion, which triggers FSH and LH release from the anterior pituitary. These, in turn, act on the granulosa and theca cells in the ovary to stimulate follicle maturation and trigger ovulation.

Detailed explanation-2: -Therefore, the pituitary secretes FSH and LH, a process which actually begins before the onset of your menses. These hormones in turn stimulate the growth of several ovarian follicles, each containing one egg. The number of follicles in the monthly “cohort” of developing follicles is unique to each individual.

Detailed explanation-3: -Gonadotrophin-releasing hormone (GnRH) is released from the hypothalamus and binds to receptors in the anterior pituitary gland to stimulate both the synthesis and release of follicle stimulating hormone (FSH) and luteinising hormone (LH).

Detailed explanation-4: -Follicle-stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) released by the hypothalamus. The pituitary gland also secretes luteinizing hormone (LH), another gonadotropin. FSH and LH are composed of alpha and beta subunits.

Detailed explanation-5: -The menstrual cycle is regulated by the complex interaction of hormones: luteinizing hormone, follicle-stimulating hormone, and the female sex hormones estrogen and progesterone.
