A plastic surgeon indicates it’s possible that smoking pot could be a cause behind the development of man boobs.
Mail Online reports that Dr. Anthony Youn, from YOUN Plastic Surgery in Detroit, says cannabis could lower testosterone levels in men, leading to the development of excess breast tissue.
The doctor also says that man boobs are caused by an imbalance in the body’s levels of testosterone and estrogen. Youn notes that gynecomastia, known as man boobs, affects about 33 to 41 percent of men in the age range of 25 to 44.
In an article for CNN, Youn noted that gynecomastia is caused by a hormone imbalance between testosterone and estrogen. When the ratio between testosterone and estrogen tips in favor of estrogen, the body responds by creating excessive breast tissue. Hence, man boobs.
Animal studies have shown that exposure to the active ingredient in marijuana can result in a decrease in testosterone levels, a reduction of testicular size, and abnormalities in the form and function of sperm.
Youn also asked and answered a question in the CNN article.
“So can smoking pot really give you man boobs?”
“Probably,” the doctor replied. “Although the association between marijuana and gynecomastia hasn't been conclusively proven, it appears very plausible. For this reason, the majority of plastic surgeons I’ve consulted with routinely inquire with their gynecomastia patients about cannabis use and recommend they stop smoking pot immediately.”
