Can anybody explain the difference between Primary and Secondary Hypogonadism?
Primary is when the problem is caused by your testes and secondary is some other reason other than your boys being the root of the problem.

Primary is when you make LH but the testes do not respond. A challenge of hCG would do little or nothing. Causes can be from hardening of the arteries, aging physical injury etc.
Secondary is when the body will not make enough LH to keep the testes working. Testing for LH and hCG is very useful.
With aging, both can be occurring.
For secondary, E2 testing would clarify if a severe HPTA repression is occurring.
Primary or secondary, almost all the time, TRT is required. Primary in a younger guy calls for consideration of a pituitary tumor or injury from a blow to the head… boxing anyone?
If the hypothalamus and pituitary are working right, primary will be high LH levels trying to beat a dead horse. This is a good diagnostic.
Thanks for the info gentlemen.
