A 45-year-old male is obliged to have his testes removed due to having developed testicular cancer. What effect is this likely to have on hits GnRH, LH, and FSH levels? Would these levels be higher, lower, or similar to a body builder who's been supplementing his workouts with anabolic steroids? Why would this be? Be very thorough here.
Answer: The testicles produce testosterone, so the removal of testicles cause a sharp fall in testosterone level. The high level of testosterone reduce the level of GnRH, FSH and LH by a negative feedback mechanism, absence of tetosterone result in increase secretion of GnRH, FSH and LH from pituitary. Thus, higher levels of GnRH, FSH and LH hormones is observed.
Anabolic steroids are the steroidal androgens that have both testosterone and synthetic androgens. By supplementing with anabolic sterids the person have a normal level of testosterone, which regulate the secretion of GnRH, FSH and LH from pituitary by negative feedback loop.
