Study Results Show Possible Mutations in Sperm of French Men

Featured News, Health & Lifestyle

Study-ResultsRecently, the results to a study were published that was conducted on more than 26,600 French men over a span of 17 years. This particular study showed that from 1989 to 2005, sperm counts have decreased by a third in the French population, and the quality of their sperm has also dropped in a significant way.

More Startling Findings

The sperm count in the French men who were studied fell approximately 1.9 percent each year. It was also found that sperm that was of a normal shape and size declined 33.4 percent. Further details about the study can be found in the report that was published in the Human Reproduction journal.

Joelle Le Moal stated that this study was the first one of its kind. There have never been any previous studies that have published such results about an entire country’s population as it pertains to the quality and concentration of its sperm. Additionally, no such study has ever been conducted to monitor the quantity and quality of sperm among an entire country of people for the amount of time that this study took place.

Men in the study who were 35 years of age experienced a drop in sperm from 73.6 million to 49.9 million for each milliliter. Though this is the case, Doctor Le Moal claimed that these men’s sperm count was still in line with the guidelines for fertility set out by the World Health Organization. The fertility norm set out by the World Health Organization is approximately 15 million per milliliter.

What is the Cause?

It is believed that there are some genetic differences that can account for the problems with the quality and quantity of sperm in French men. Researchers are not sure which of these genetic mutations they may be, as more research needs to be done to pinpoint the exact genetic factors that play a role in the decrease in the quality and quantity of French men’s sperm. However, what they do know is that 75 percent of the mutations that cause problems with fertility in mice will affect only men, not women. It is highly speculated that women have more genetic safeguards that protect the viability of their eggs than men do with sperm. Another speculation researchers make is that more genes play a role in sperm production than do the production of women’s eggs.

Presently, it is not possible to determine whether or not any future studies will be conducted on this particular subject. It is safe to assume that there may be due to the fact that the topic of sperm mutations in French men is growing in popularity. Perhaps, interested lay people and researchers may demand that further consideration is given to this matter and more studies are conducted to provide more insight into the problem.
