Countdown is a shocking book that reveals the low levels of male fertility around the world

American geneticist Sasha Swan has revealed that the effects of chemicals have become a major contributor to declining fertility in men and creating more problems and physical deformities for present and future generations.

According to the Intercept, the author of the book “Countdown” oversaw a study that ran from 1973 to 2011 and included 42,935 men, which found their sperm count to be 59 percent.

In his new book, Swan highlighted the effect of chemicals in everyday products on the cause of many birth defects, including an increase in the number of children born with small genitals, a high rate of impaired sexual abilities, decreased fertility and even an impact on stereotypical male and female behaviors.

She pointed out that some experiments have revealed the effect of phthalates, which are chemicals included in many products such as cosmetics, cleaning, pesticides and canned food, on the birth of mice with deformed genitals after exposure to these substances for a period of between 18 and 21 days.

She said that after studying the effect of phthalates on humans, it was found that male children exposed to four types of these substances during the first third of their presence in their mother’s womb became more short.

Swan also confirmed a relationship between women’s phthalate levels and sexual satisfaction, as Chinese researchers found that women with high levels of bisphenol A, known as BPA, were more likely to have problems. sexual intercourse, including decreased desire to have sex.

Regarding the effect of chemicals on stereotypical behavior of both sexes, the American researcher explained that in one study, mothers were asked to determine how their children played with plastic guns and dolls, to convey that male children who were exposed to substances that deformed the genital area were further removed from male play than normal children.

She said this showed an impact on language learning, as studies had previously shown that women are more proficient at acquiring languages, but that the effect of chemicals weakens the skills of girls.

The researcher pointed out that these changes now have dual effects, as the changes they make are part of the genetic genes a person carries and passes on to future generations, which will also continue to be affected by the chemicals they are in. exposed.
