Question:

Hormones for the menstrual cycle are produced by

Options:

1. ovaries only
2. uterus only
3. ovaries only
4. ovaries and anterior pitutory

Solution:

Menstrual cycle is regulated by certain hormones, some of which are secreted by the pituitary gland. The pituitary gland is stimulated by factors produced in the hypothalamus. The hormones produced by the pituitary gland influence the ovaries. The hormones secreted by the ovaries effect the walls of uterus. It can be explained as: Gonadotropin releasing hormone (GnRH) also called Gonadotropin releasing factor (GnRF), is secreted by the hypothalamus of the brain, which stimulates the anterior lobe of pitutory to release follicle stimulating hormone (FSH) and luteinising hormone (LH). FSH stimulates the ovarian follicles to produce estrogens during proliferative phase. LH stimulates the corpus luteum of the ovary to secret progesterone.
