Oligospermia aka low sperm count is a medical symptom affecting men and means having less than 20 million spermatozoa per milliliter of ejaculate. For relatively normal sperm count is considered 20 million or more per ml of semen.
Low sperm count is one of the main causes of male infertility. Although it takes only one sperm to fertilize the egg, the odds of a single sperm to reach the egg are considerably low if the overall sperm count is less than 20 million per milliliter. This is not a rule, just the common case, which means there are exceptions.
To conceive a child it is enough at least 60 percent of the spermatozoa to be normally shaped and have good motility. The minimum count of 20 million spermatozoa to conceive a child is not as accurate as one might think. Many men diagnosed with oligospermia have successfully fathered children.
Why do I have a low sperm count – that is the million dollar question in case of oligospermia
Unfortunately nine out of ten doctors will not be able to answer it. They will just diagnose you with idiopathic oligospermia, i.e. cause unknown. The tests that can answer that question are expensive and currently available only in labs conducting researches in that field, which explains why they are being used seldom to determine the exact causes of that common men’s problem.
However, we must admit that this test is a breakthrough for the modern medicine and has enlightened the cause of low sperm count – oligospermia is probably caused by microdeletion on the Y-chromosome. Which most likely proves that it is a genetic disease and as we already know has nothing to do with men’s general health, physique, and sexual or diet habits.
