I have an at home microscope kit I use to check on my husband's sperm. It confirmed (at least part) of the reason I'm not getting pregnant. He has very low sperm count. I had him start taking these One a Day pre conception vitamins to help boost sperm count. Well his count after one and a half months of taking vitamins has gotten worse. It used to be 10 million, now it's dropped to 2 million. 😭 It takes about 3 months to create sperm in the body, so I'll check in about once a month while I have him on these vitamins to see if they help. But I'm starting to think he has the same problem his twin brother has, to where the sperm was going inside? Not sure how exactly that happens, but they say cold medicine can help with that? I have to ask my sister in law more about that exactly.
