Thank you for your reply.
He is seeing a specialist who is also consulting another specialist friend of his. I believe he is an endocrinologist.
We don't have any kids, but they are definitely in our near future plans. The fertility issue worries me a lot. He wants me to go with him to his appts with the doctors now and I am more than happy to do that. He seemed devastated when I told him that I read some stuff about possible fertility problems.
The hairy side effect doesn't concern me at all. He is Italian and he is pretty hairy, but not hairy enough for a mediteranean man so him getting a more hairy chest will be more of a turn on to me (lol i hope that doesn't sound weird).
What numbers are we talking about? My husband is in the mid 200s.
My H's numbers were lower than your H's. But he is also almost 50, not 29. My H's normal level should be about 500 - 600 for a man his age - his last was around 430 with his current dose. He gets a higher dose the next time he gets an injection.
My H has primary hypogonadism - he had a medical condition that caused testicular atrophy, so his low T is primarily a result of not having his 'boys' both working properly. It was just a slow decline for him and he just thought he was aging (and while we knew about the medical issues with one of his testicles, we didn't realize it would/could impact his T levels), but decided to talk to the doc about his symptoms and convince the doctor to test him (I had to convince my H first, though, to even bring it up - and it was primarily because of posts I had seen on here about low T).
Since your H is so young, it's good they are exploring what may be causing his low levels.
We are done having kids, so fertility was not a factor. But I do know that hormone replacement causes your body (e.g., your pituitary/hypothalamus in your brain) to sense more hormone in your body and therefore not stimulate your body to make any more - and that can have a potential impact on a man's fertility. I think if you are concerned about his fertility, you should simply bring it up with his doctors - and try and not worry too much about it - take one step at a time and try and not fret about things you don't know for sure - he could have completely adequate fertility for all you know.
I will be thinking about you and your H in the days ahead and hoping and praying for the best for both of you.
