My husband was told that his sperm needed both water wings and a map.......while he had an above average sperm count none of them could swim. After a sperm wash (where they take away the bad sperm) there was nothing left. We were told that we had next to nothing chance....less than 1 percent. After 5 years of treatment IVF etc (nothing worked) we got pregnant perhaps totally by chance....but something really interesting is that both my children had the same due date. I have heard that there are certain times in the year better than others to get pregnant. Our doc told us that the sperm in the man is 90 days old. When sperm is hot....it's not as good as when it's cool. Many countries use hot showers as a form of birth control (not really effective, but there is some difference in sperm quality) He then told us to try to get pregnant after it has been cold for 90 days. I got pregnant both times the first week of March. I tried positions/standing on my head.......you name it I did it...(ugh when I look back at what I tried). However, for me making my hubby wear boxers and the cold weather worked. (or perhaps it was just a lucky shot...........)
