Explain the negative feedback system involved in managing the levels of sex hormones.

Correct Answer

verifed

verified

Levels of sex hormones are regulated by two hormones secreted by the pituitary gland: FSH (follicle stimulating hormone)and LH (luteinizing hormone).FSH stimulates follicle development in females and sperm production in males.LH regulates estrogen secretion in females and testosterone production in males.In addition,the hypothalamus secretes a substance called GnRH.These hormones are regulated by a negative feedback system.If the level of sex hormones rises too high,the hypothalamus and the pituitary gland reduce their stimulation of the gonads,decreasing the production of sex hormones.If the level of sex hormones falls too low,the hypothalamus and the pituitary glands increase their production of the sex hormones.
