Low Testosterone... totally baffled

Atty

My husband and I are a fertility mess... according to our doctors. We finally decided to take the leap to do <a href="https://glowing.com/glow-fertility-program">IVF</a> and husband had 0 sperm in the sample. Totally devastating, but they say it’s because he has low testosterone. He is not the norm. There is no lack is sex drive or erections, and I am at a total loss. He doesn’t fit the mold in hair growth and hasn’t taken supplements. Anyone else out there with advice or suggestions?
