Male infertility, threatened four men out of ten

Male infertility, threatened four men out of ten. Continues to decline, the average concentration of sperm, pollution and environmental factors the main causes. The analysis of the center of reproductive medicine .

Continues to decrease male fertility. Halved in the second half of the last century, the average concentration of sperm in the 2000s has decreased by about 15%. "We estimate that about four out of ten men in the age group 20 to 45 years old may have a low sperm quality, then problems to have a child," he pressed specialist in Reproductive Medicine of the fertility center , only one in four men have a semen quality considered excellent; the quality would be fair to 20-30% and this may take longer to arrive at a conception; while for 10-15% would be just enough, or to the limit with infertility problems.

"By the standards of the World Health normal sperm concentration it is 15 million per milliliter; below this threshold, the talk is of low sperm counts, then of possible problems in getting a pregnancy, "continues . "Based on these values ​​it is important that you pay more attention to reproductive health in humans through awareness campaigns targeted."The quality of the male seed depends on several factors. "There are many elements that can affect the mean concentration of sperm and their motility. Among the causes that have led to the lowering of quality there are environmental factors. We live today in an environment far more polluted and, compared to a few decades ago, we are more easily subject to come into contact with harmful chemicals. Some plastics, pesticides and nitrates are so-called endocrine disruptors that can cause fertility disorders. The thesis of environmental causes is supported by several studies of migration: people moving from one place to another tends to take the same problems found in the natives', continues Bellavia. "Even sexual freedom is a causative factor as it leads to a greater spread of infections that can impair male fertility. Certainly not the last, unhealthy lifestyles - such as smoking - lead to a deterioration in the quality of the seed, lowering the traditional parameters of concentration and sperm motility. "

In many cases the problem is solved: "Thanks to new specific examinations, sometimes simply follow the targeted treatments, or simply to change habits, to return to a full reproductive health", continues . The specialist of reproduction should in fact encourage the prevention of infertility through important advice to the couple on the lifestyle and how to avoid those toxic substances that can have a negative influence on fertility. The situation is different in cases where infertility is diagnosed. Continue the specialist ProCrea: "It is estimated that a third of men defined infertile, when subjected to adequate care, failure to obtain a natural paternity. The remaining can enlist the help of assisted reproduction. Even men once considered absolutely sterile, can become fathers, recovering sperm directly from the testis and injecting them into the ovum (ICSI). But in 3% of infertile couples, there is a condition of azoospermia, it is necessary to resort to heterologous fertilization using donor sperm.
