40 to 300 million is the normal range for healthy sperm count. Counts below 10 million are considered poor; counts of 20 million or more may be fine if motility and morphology are normal. Also, the concentration of spermatozoa should be 20 million per ml, semen value should be 2 ml and total number of spermatozoa in the ejaculate should be at least 40 million.
Curejoy Expert Dipti Mothay Explains:
Sperm count is the measure of the number of spermatozoa (a motile sperm cell) per ejaculation or per measured amount of semen, used as an indication of a man’s fertility. Semen Analysis is the single most important test of male fertility.
Healthy Sperm Count
40 million to 300 million is the normal range for the number of sperm per milliliter. Counts below 10 million are considered poor; counts of 20 million or more may be fine if motility and morphology are normal.
The World Health Organization provides a definition of a ‘normal’ sperm count:
– The concentration of spermatozoa should be at least 20 million per ml.
– The total volume of semen should be at least 2ml.
– The total number of spermatozoa in the ejaculate should be at least 40 million.
– At least 75 per cent of the spermatozoa should be alive (it is normal for up to 25 per cent to be dead).
– At least 30 per cent of the spermatozoa should be of normal shape and form.
– At least 25 per cent of the spermatozoa should be swimming with rapid forward movement.
– At least 50 per cent of the spermatozoa should be swimming forward, even if only sluggishly.
– In addition, more is not necessarily better, as too high a sperm count can also result in fertility problems.
Measuring sperm count is a very technical business and results can be affected by many factors, including the length of time between ejaculation and semen sample analysis, and how the sample is kept when being transported to the lab.
It’s quite surprising how many dead and abnormal sperm can be present in a ‘normal’ sample. Also there can be enormous variation in sperm count in an individual, even over a few days. Sperm count is only an indication of fertilizing capacity and a normal count does not guarantee absolute fertility success.
