A man with a low sperm count (Oligospermia) :-

CAUSE & TREATMENT Posted By: Vinit Kumar

Many infertile men are obsessed about their low sperm count - and this seems to become the central concern in their lives. Remember that the real question the man with a fertility problem is asking is not: What is my sperm count or what is my motility ? But - are my sperm capable of working or not? Can I have a baby with my sperm? Since the function of the sperm is to fertilize the egg, the only direct way of answering this question is by actually doing IVF for test fertilization. This is, of course, too expensive and impractical for most people which is why the other sperm function tests have been devised.

The major problem with all these tests, however, is that they are all indirect --- there is no very good correlation between test results, pregnancy rates, and fertilization in vitro for the individual patient. This is why offering a prognosis for the individual patient based on an abnormality in the sperm test result is so difficult, and why we find that different doctors give such widely varying interpretations based on the same sperm report.


This is really not surprising when you consider how abysmal our ignorance in this area is - after all, we do not even know what a "normal" sperm count is! Since you only need one "good" sperm to fertilise an egg, we do not have a simple answer to even this very basic question! While the lower limit of normal is considered to be 10 million progressively motile sperm per ml, remember that this is a statistical average. For example, most doctors have had the experience of a man with a very low sperm count (as little as 2-5 million per ml) fathering a pregnancy on his own, with no treatment. In fact, when sperm counts are done for men who are undergoing a vasectomy for family planning, these men of proven fertility have sperm counts varying anywhere from 2 million to 300 million per ml. This obviously means that there is a significant variation in "fertile" sperm counts, and therefore coming to conclusions is very difficult for the doctor (leave alone the patient!)
