Hitman42 [59]

Answer:

Clomid tricks the body because it tells the brain that estrogen levels are low, thereby leading to higher production of this hormone  

Explanation:

There are many types of hormones that are regulated by the negative feedback mechanism (where hormone feeds back to decrease its production). Clomid is a drug used to treat female infertility by making the body think that the concentration of estrogen is low, which induces the secretion of Follicle-stimulating (FSH) and luteinizing (LH) hormones by the pituitary gland. The estrogen hormone exerts negative feedback on the Gonadotropin-releasing (GnRH) hormone, which is responsible for the release of FSH and LH. High FSH levels stimulate the growth of follicles in the ovaries, which will be released during ovulation.
