The chemicals of the modern world harm reproductive health.
Penises are getting longer, and that should worry us, say scientists. The average penis length in the world has increased by 24% over the past 29 years, according to a new meta-analysis by Stanford University, a European news portal reports.
data from 75 scientific papers published between 1942 and 2021, which included penis length information from 55,761 men. They found that over the past three decades, average erectile length has increased from 4.8 inches (12.1 cm) to 6 inches (15.24 cm).
Such rapid growth is alarming, warns one of the study's authors, Dr. Michael Eisenberg, "The increase has occurred in a relatively short period of time. Any cumulative change in development is worrisome because our reproductive system is one of the most important parts of human biology. If we are seeing such rapid changes, it means that something significant is happening to our body."
Some factors can cause an increase in the average length of the male penis. One of the main likely causes is the prevalence of harmful chemicals in pesticides and hygiene products. "These endocrine-disrupting chemicals - there are many of them - are present in our environment and our diet," says Michael Eisenberg. - As our body constitution changes, so do our hormones. Exposure to chemicals is also thought to cause earlier puberty in boys and girls, which can affect genital development."
What other effects do chemicals have on human reproductive health? Studies show that it is quite large. For example, sperm counts in men in Western countries dropped 59% between 1973 and 2011, according to a meta-analysis of 185 studies involving 45,000 men.
Chemicals can also affect the future fertility of children still in the womb. A recently published Danish study found that women's exposure to dangerous "everlasting chemicals" early in pregnancy can reduce sperm count and quality in adult male children.
