In 20 years, a 40% drop in the number of spermatozoa in men would have been observed, aggravated by a drop in quality. These are the results of a very serious French study. Some researchers make it a problem as important as that of the warming of our planet.
Among the causes mentioned: first, pollution. We are surrounded by chemicals on a daily basis. Recently, a French team demonstrated the toxicity of phthalates on the germ cells which constitute the precursor of spermatozoa. However, phthalates are found, among other things, in many plastic packaging, in PVC, etc.
Pesticides also contribute to the spoilage of semen.
We also mentioned heat, because the production of sperm is an extremely sensitive to temperature. The sperm must be kept at a temperature between 33 and 34 ° C. Depending on the temperature, the bursae contract or relax in order to keep this temperature constant.
An increase in the temperature of the testes slows down or even stops spermatogenesis. And it is from this observation that we accused the jeans too tight.
Food is also in the crosshairs, as well as tobacco, which is arguably the main cause. Smoking will destroy the blood vessels in the male reproductive system. At the level of the penis, this is responsible for an alteration in the quality and duration of the erection. In the testes, vascular alterations lead to a more or less irreversible destruction of the production of sperm.
We must also add alcohol, but we will also hurt Sunday sportsmen: the trauma caused by cycling and horse riding, as well as the increase in local heat, hampering the circulation of blood, threaten the quality of sperm.
And finally, stress, which our modern world is accustomed to, but here, it would still be necessary to demonstrate to me that our modern life is more stressful than that of contemporary wars and famines.
Rather, I would like to draw your attention to another concern than this semen weakness which doesn’t worry me more than that, to raise the debate and leave those family gems that are in peril with wearing jeans that are too tight and wearing them too tight. temperature rise, to evoke the real concerns about the future of our Y chromosome, transmitted from father to son, which is the main difference between man and woman.
