OBG · Infertility and contraception: hypogonadotropic hypogonadism in men
Sample itemA man with azoospermia has low FSH, low LH and low testosterone, with a normal pituitary MRI, and wants fertility. What is the treatment of choice?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. hCG with recombinant FSH
In hypogonadotropic hypogonadism the testes are normal but unstimulated. hCG replaces LH and drives Leydig cell testosterone, and FSH supports spermatogenesis, often restoring sperm in the ejaculate.
Option by option
A. Testosterone enanthate injections
Exogenous testosterone suppresses gonadotropins and further impairs sperm production.
B. hCG with recombinant FSH (correct)
Correct. hCG with FSH replaces the missing gonadotropins and restores spermatogenesis.
C. Varicocelectomy
A varicocele is not the cause of low gonadotropins.
D. Testicular sperm extraction
Surgical sperm retrieval is unnecessary when medical treatment can work.
