Abstract

Do you know how good the quality of your semen is? Is it as good today as it was 10 years ago? Unless you are getting it tested regularly by a reputable lab, or are fathering babies on a regular basis, you will have no real way of knowing. In fact it’s a complex issue for several reasons. For a start, to measure sperm quality you need to take various things into consideration. It’s not just by the number of sperm, but how effectively they swim, whether they look like typical sperm, etc. But even among fertile men there is a lot of variation in sperm characteristics, so it isn’t straightforward to identify what is abnormal for any particular man. This is unfortunate, because sperm quality is generally considered be a good overall measure of health, so it’s in men’s interests to know whether our sperm is in good condition or not. Sperm quality is not only important to the individual man, but because it has been suggested that men worldwide are experiencing poor sperm quality, this issue has implications for the future of the human race.
