Hi and

My DH and I have a 21-month old son (took about 6months to conceive) and now have been TTC #2 for about a year. Several months ago, my DH had a SA and it was very low (3.2 million/ml with 36% motility). He has been taking tons of vitamins and had surgery on a varicocele in his testicle 7 weeks ago.
I would be curious to know what your DH's counts are and what your doctor considers medically sterile. If you've been pregnant three times, I would think his sperm are going somewhere....it truly does just take one and there are several of us ladies on here who are a testament to that. But I'm sure it is possible that the medication is just now making things worse.
Good luck to you! I hope you stick around here
