Question

True/False

After taking testosterone injections (supra physiological dose, i.e. high) every week for 6 months the following would be observed: # 6-9

6.-------Increased plasma testosterone levels

7. ____ Increased ICSH plasma levels

8. ____ Decreased FSH plasma levels

9. --------_Increased levels of Gonadotropin releasing hormone levels

Answer 1

6) True

Explanation: Injection of high dose of testosterone would lead to increase plasma testosterone level.

7) False

8) True

9) False

Explanation: high level of testosterone negatively inhibit both pituitary hormone secretion and hypothalmic secretion.hence High level of testosterone inhibits the GnRH secretion from the hypothalamus which in turn reduces the release of both FSH and ICSH from the anterior pituitary.

So there would be low level of Gonadotropin releasing hormone, low level of ICSH and low level of FSH
