future of male fertility
The most important warning about male fertility deficiency came from the British Medical Journal in 1992, where researchers analyzed about 61 studies on the number of sperms in men between 1940 and 1990 in about 20 countries. It was found that the average number of sperm in men has decreased from 113 million sperms per milliliter to about 66 million, a decrease of 42% over a period of fifty years.
In the following studies, which were conducted in several regions of the world, it was found that there is a gradual decrease in the number of sperms. In an English study, it was found that the number of sperms in men has decreased by 33% during the past twenty years, and there is also a Scottish study that proved that the number of sperms in men Those born in 1969 are 41% fewer than men born in 1941.
These successive studies have led the World Health Organization to bring down the minimum normal number of sperms from 80 million in 1956 to 40 million in 1972 and then 20 million in 1988, and it is expected that the minimum normal number of sperm is about 10 million in the next report. To the World Health Organization.
Despite this shortage in the number of sperms, the reproductive capacity of many men is still normal, and this is due to: firstly because the number of sperms required to fertilize the egg is much less than what a man ejaculates, and secondly because many diseases that affected the fertility of men and women in the past, such as Infections of the urinary and reproductive system, sexual diseases and chronic diseases are now easy to treat thanks to the great scientific progress, which contributed to preserving the fertility of more men, but certainly there is an increase in the percentage of patients in infertility and reproductive clinics and there are some pessimistic scientific opinions that say that male fertility is threatened It will disappear completely within two centuries and they call this the lost future of male fertility.
