Suggestions??

My husband has a low sperm count of 5000, he was on clomid for 3 months which did not help. His count was still 5000, his urologist says we just need to go do ivf, Right now we just can’t afford ivf, and didn’t offer to try anything else or anything, I feel that he just didn’t want to help us, What are some things that helped your husbands low count, He takes a one a day vitamin, vitamin c, vitamin d, and vitamin e, and another vitamin I just can’t think of the name of right now, We are literally willing to try anything, I ovulate every month, it’s just not at the same time every month, I temp and use opks to know when I ovulate, my dr feels I don’t need to be on anything at least until we get his count up.
