After TTC for almost 2 years and personally having tests (blood tests and scans which all came out fine) my DH has finally had a sperm test and it turns out he has low sperm density (a quick google implies this is the same as a sperm count). Mobility is normal, apparently.
Did anyone else go through this? What can be done about it?
He doesn’t smoke or eat unhealthily (eats pretty healthily) but I would say he doesn’t do lots of exercise. Maybe about one intense thing a week, and daily longish dog walks, that’s it. Drinks maybe a bottle of beer or two every couple of days.
I bought him supplements about a year ago, but he takes them maybe once a week 
It’s secondary infertility for us, which is why he didn’t much care for getting checked out until now.
I know this is very unhealthy of me, but I feel a bit annoyed (secretly) because after two years of TTC I am now 40 and have been ovulating and taking supplements and exercising and have quit drinking and do the ovulation strips (on and off, they were making me obsessive!) and tracking cycles and so on and so on. It feels like we’ve wasted my body’s chances because I’m no longer in my 30s.
My secret resentment comes from the fact that he hasn’t done anything to change and we’ve just discovered it’s likely his sperm that has held us back (I know I shouldn’t think that way - I will not tell him).
Is this it for us in all likelihood? I doubt I can get him to change much, tbh. We also only DTD 2-3 times a month as he has a low sex drive - probably connected?
It’s so frustrating. I know I should stop thinking about this now! (I keep telling myself with each month that I will, but then I don’t!)
