ANATOMY

Detailed explanation-1: -This system is called the hypothalamic–pituitary–gonadal (HPG) axis. 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-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: -The anterior pituitary, where Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) are secreted by gonadotropes. 3. The gonads, responsible for the production of both sex steroids and gametes, under the influences of LH and FSH.

Detailed explanation-4: -The hypothalamus begins the process of ovulation by releasing GnRH in a pulsatile fashion. This pulsatile release causes the anterior pituitary to release LH and FSH, which then act on the ovarian follicle. This follicle is made up of 3 essential cells: theca cells, granulosa cells, and the oocyte.

Detailed explanation-5: -Your anterior pituitary is one of two lobes that make up your pituitary gland, which is a small, pea-sized endocrine gland located at the base of your brain. Your anterior pituitary is responsible for creating and releasing over six different hormones that affect many different bodily processes.
