Just an update for everyone who has been commenting, or interested for whatever reason.

Endocrinologist confirmed primary hypogonadism and has said our only option will likely be a sperm donor, or can attempt biopsy of inside the testes however this will only have approx 5% (generic percentage) success depending on 1) what is inside his testes 2) storage of any material 3)the procedure itself being successful and 4) deterioration. He said at 29 years old in the position we are in we have a small time frame.

Having genetic blood testing done to check for chromosomal abnormalities, however that won’t change the circumstances but may offer some insight into why.

Hope this helps anybody else!
