Today's topic on the radio where I collaborate was infertility. It bothers me greatly that when we address this issue take responsibility, even blame, the woman it. The funny thing is that they all feel entitled to comment further without knowing about it. Let me make clear that the problem of infertility is not the fault of women, although it is true that the responsibility of pregnancy is entirely ours, the design is not the responsibility of both.
It is true that more and more difficult to conceive "at the right time" and why so much talk about infertility, but it is not the biological inability conception of women. It is considered that the inability to conceive a third is due to causes attributable to women, third man and one third from several factors such as stress.
actually the main problem as regards women is mostly delayed motherhood: the ideal biological age for having children is between 20 and 30 years . However, there are now from 30 and closer to 40, when the chances of pregnancy are only 5% in each cycle.
According to Dr. Marisa López-Teijón, Director General of Institut Marques, "a woman is born with an endowment and set of eggs from the first rule are fading and aging. So that at age 35 are less -only 10% - and are of lower quality since the passage of the years causes changes in the process of meiosis of chromosomes. "
These chromosomal abnormalities are more common with increasing age of women and make that in most cases, pregnancy does not occur or does not evolve. According to the Institut Marques, to 35 years, 40% of a woman's embryos are abnormal; at age 38 to 65% , and 41 years, 80% . Why we have worked new techniques to curb the pressure of the biological clock. For example, the vitrification of eggs, which allows a woman to freeze their eggs when they are still young, for use after a few years when you decide to become a mother.
man As one of the biggest causes is the deteriorating semen quality . The decline in semen quality in industrialized countries is not a new phenomenon, the first data were observed over 30 years, and from then until now the WHO has had to go down the bar on what it considered normal to accommodate the gradual qualitative decrease observed in the male population. Thus, in just 25 years, WHO has been normal to consider a concentration of 100 million sperm per milliliter of semen to lower it more than 75% to 20 million, and reduced further raised to 15 million sperm / ml. The reasons for the plummeting not lie in lifestyle traditionally regarded as harmful to fertility. According to several studies is the key industrial pollution by chemicals and is explained by the action on our body of compounds commonly used in industrial and agriculture known as "endocrine disrupters" that affect our health and especially to male fertility in the embryonic stage.
therefore clear that infertility can not be attributed to the woman, but both sides, in a woman because after a certain age it is becoming less number of eggs. In men because semen quality has deteriorated dramatically in industrialized countries.
