Sperm Trouble

I have been trying for baby #2 for 7 months now. I went to my gyno today and got an u/s bloodwork stat and was told that my ovaries and etc look really good and even looked like from my u/s that I would ovulate soon. So she asked me had hubby had his sperm checked, because it looks like it could be him and not me. He jus turned 42 and I asked him to get it checked before only because his Dr had said his count may have gone down with his age. He really insist on it being me and not him. I set him up and everything with the specialist to get it done and that was 2 days ago and he has yet to get it done. I feel like he knows it may be him that's why he won't go, Dr said she could put me on clomid but what would be the point if his count of low and needs a boost...... So annoying!!!
