Hormone effects are pre/testicular/post
pre testicular
Failure of immediate coagulation of semen suggests ______
absence of seminal vesicles
_____ is secondary to congenital defect in GnRH secretion by hypothalamus and is associated with cranio-facial defects, maldescended gonads, and anosmia.
Kallman’s
_____ is associated with pituitary microadenmoa and gynecomastia.
hyperprolactinemia
_______ involves loss of 21 hydroxylase which prevents progesterone converting to cortisol and instead converts to testosterone.
