Why men are increasingly becoming infertile

2 Mins read

Male fertility is declining to the extent that men are today half as fertile as men of previous generations. The average man is now producing fewer viable sperms and quantity than his father and grandfather did. Today, sperm count around the world is dropping at a rate of two per cent every year and has more than halved in the past 50 years.

Sperm counts have dropped over the years. What used to be regarded as “normal” sperm count is going down. Even the World Health Organisation, WHO, and other reputable health bodies are aware that men are increasingly becoming infertile.

Daunting research evidence

Recently, a group of researchers from Hebrew University and Mount Sinai Medical school published a study showing that sperm counts in the US, Europe, Australia, and New Zealand have fallen by more than 50 percent over the past four decades. There are studies suggesting that the trend could be worldwide.

In Europe, records show that an average of 1 in 18 men has low sperm count, and the numbers of men who are affected are rapidly increasing. In Denmark, about 40 percent of the men have low sperm count. The situation is no better even in the United States of America, probably worse. Clinical records show that in Nigeria, 25 percent of couples are infertile, and that half of the causes are due to male factor issues related to poor sperm parameters.

An assessment of hospital data from leading tertiary health institutions revealed that a significant proportion of male infertility cases are either due to low sperm counts or poor sperm quality, or a combination of both.

A paper published almost a quarter of a century ago of a review of 61 studies of semen quality carried out between 1938 and 1990, found that sperm quality was declining.

No less than 40 percent of fertility issues are male related, hence male infertility is becoming more predominant as a result of men being diagnosed with low sperm count and poor sperm motility. More frequently, men are being identified as the reason why infertile couples are not getting pregnant.

Genetic dilemma

A man’s sperms carry half the genetic material necessary to make a complete human being. A woman’s egg holds the other half. Increasingly, experts are reporting incidences of men with genetically fragile sperms.

Such sperm have fragmented DNA chains, which make them to be of low quality and less capable of fertilisation. Male infertility can be caused by various factors such as hormone disorders, illness, injury to reproductive anatomy, obstruction or sexual dysfunction, etc.

These factors can temporarily or permanently affect sperm and prevent conception. Some disorders become more difficult to treat the longer they persist without infertility treatment
