Since approximately half of infertility problems involve the man, we typically recommend obtaining one or two sperm counts prior to the workup of the woman, unless there are obvious female problems. There is a dietary supplement that has been advertised but, to date, there is insufficient evidence to show that it really changes fertility. That is actually a myth. There is very good evidence that shows that tight jeans and tight underwear, as well as all types of clothing do not have any effect on sperm count. There is really no difference in boxers versus briefs, tight jeans versus loose pants.
Vasectomy reversal can be successful.
It is dependent upon several factors including the time from vasectomy, the experience of the surgeon, and type of vasectomy reversal performed. I leave that up to the couple. The definition of infertility is inability to get pregnant after one year of unprotected intercourse. Some couples want to know before a year, and it is not unreasonable to start with something easy such as a sperm count. Retrograde ejaculation is fairly uncommon and is typically associated with a neurologic disorder or previous abdominal surgery.
