A study warns that penis size is shrinking due to contamination


Dr. Shanna Swan, a researcher at Mount Sina Hospital in New York, has discovered that chemicals called phthalates are causing human babies to be born with malformed genitalia

Penises shrink and genitalia deform due to contamination, an environmental scientist, Dr. Shanna Swan, in a new book detailing the challenges facing human reproduction.

Dr. Swan writes in her book titled Count Down that humanity faces an “existential crisis” in the fertility rates as a result of phthalates, a chemical used in the manufacture of plastics that affects the hormone-producing endocrine system. As a result of this contamination, an increasing number of babies are born with small penises, Swan says.

The doctor. Swan, a professor of environmental medicine and public health at the Hospital Mount Sinai from New York City, he based his work on a series of peer-reviewed research studies.

A study published in 2017 found that sperm levels among men in Western countries had decreased by more than 50% in the past four decades after examining 185 studies involving nearly 45,000 healthy men.

According to public Sky News, in her book Dr. Swan examines “how our modern world is threatening the sperm count, altering male and female reproductive development and endangering the future of the human race. ”

Dr. Swan’s investigation began by examining the phthalate syndromeThis was observed in rats who discovered that when fetuses were exposed to the chemical, they were likely to be born with shrunken genitalia.

He discovered that male human babies who had been exposed to the phthalates in the uterus they had a shorter anogenital distance, something that was related to the volume of the penis.

The chemical in question has an industrial use to make plastics more flexible, but Dr. Swan says it is is transmitting to toys and food and, therefore, damaging human development.

The phthalates They mimic the estrogen hormone and therefore disrupt the natural production of hormones in the human body, which researchers have linked to interference with infant sexual development and adult behaviors.

Dr. Swan believes that the rapidly declining fertility rate means that most men will not be able to produce viable sperm by 2045.
