in primary hypogonadism condition what will FSH and LH be doing?
increasing in attempt to stimulate gonads
if the condition is “secondary” where will the problem be?
- in the hypothalamus not producing enough GnRh
- pituitary that fails to respond to secretion of LSH or FSH.
What do you measure first in hypogonadism?
- FSH and LH
what lab values indicate hypergonadotrophic hypogonadism (PRIMARY)

they may lose the characteristics talked about in hypogonadism pre-puberty if severe enough and/or of sufficient duration (usually years)
-testes will decrease in size if primary hypogonadism, damaging seminiferous tubules
do testes decrease in secondary hypogonadism?
not to a recognizable degree
phallus doesn’t decrease either
When do symptoms of hypogonadism begin?
a few weeks within onset of testosterone deficiency
what are the common symptoms of hypogonadism?
