High number of abnormal sperm

My husband just got a semen analysis and they said he has a high number of abnormally shaped sperm. They referred him to a urologist that specializes in infertility, but we can't get in for 2 months. I have just started doing some research, but has anyone else experienced this that can offer some advice? I'm looking specifically for things we can do at home to improve this, and also if anyone has gotten pregnant naturally with this diagnosis. I'm feeling pretty discouraged. I'm 33, TTC baby #1, I'm also currently taking clomid 100 mg days 5-9 of my cycle.   Thank-you!
