Additionally, this alerts us to an important characteristic of the MCAT. For this biological process to be carried out, certain organs and structures are required in both the male and the female. A negative feedback system occurs in the male when sperm counts get too high (over about 20 million/ml): rising testosterone levels cause Sertoli cells to release the hormone inhibin, which acts on the hypothalamus and pituitary gland to inhibit the release of FSH and LH.
