Why are sperm counts declining pregnancy?
It seems that average sperm counts are in decline in the developed world. Although semen analysis is probably more accurate now than it once was, which may account for some of the differences in sperm counts compared to 50 years ago, it does appear that there are a variety of factors (including the increased amount of oestrogenic compounds in our drinking water) that may be affecting sperm production. It is difficult to give a precise figure for average sperm count now compared to 50 years ago, and to provide precise causes – if indeed there is a problem – but there is no doubt that more men are coming forward with fertility problems than before. This is probably due to a cultural shift, and an increased awareness and acceptance that men can be the cause of a couple’s fertility problems.
