About Me
I came to the U.S. at age of 12 with my mother. We settled in sunny Florida, which was quite a contrast to Minsk. I have always been fascinated by sex and relationships. Sex Secrets is where I share sex advice, experiences, news, and sometimes a little humor. If you have a question about sex that you prefer not to post in the comments, you can email me at svetlanaivano(at)yahoo.com.

Why Levels of Sperm in Men Are Falling

Sperm counts in human males have fallen by about half in the last fifty years, and scientists believe they now understand the cause.

If scientists from Mars were to study the human male’s reproductive system they would probably conclude that he is destined for rapid extinction. Compared to other mammals, humans produce relatively low numbers of viable sperm – sperm capable of making that long competitive swim to penetrate an unfertilised egg.

As many as one in five healthy young men between the ages of 18 and 25 produce abnormal sperm counts. Even the sperm they do produce is often of poor quality. In fact only between 5 and 15 per cent of their sperm is, on average, good enough to be classed as “normal” under strict World Health Organisation rules – and these are young, healthy men. By contrast, more than 90 per cent of the sperm of a domestic bull or ram, or even laboratory rat, are normal. Read more
