A research team made at least one curious discovery: the average size of the human penis is changing. According to scientists, in the last 30 years, the erect phallus has grown 24% larger than before. The cause of the growth is still unknown, but it’s possible that it’s related to hormonal imbalance.
To find out how the average penis size has changed in the past, experts conducted a systematic review on this topic. The team collected 75 scientific studies conducted between 1942 and 2021 that reported the penis length of 55,761 men. It was then analyzed how the average has changed over the decades.
The research was published Tuesday (14) in The World Journal of Men’s Health, where the study’s authors summarize: “The average erect penis length has increased globally over the past three decades.”
What is the world average penis size?
After reviewing the data, the researchers point out that penis size increased from 12.1 centimeters to 15.2 centimeters. “The increase occurred in a relatively short period of time,” says Michael Eisenberg, a urologist at Stanford Medicine and one of the study’s authors, in a statement.
The problem is that the causes of this increase are still unknown. “When we see such rapid changes [no tamanho do pênis], means something powerful is happening to our body. We must try to confirm these findings, and if they are confirmed, we must determine the cause of these changes,” emphasizes the doctor.
Hypotheses about why the penis grows
Although it is not known why the human penis grows, there are some hypotheses that could explain the situation, such as: B. Male lifestyle changes and exposure to chemicals.
“There are several factors at play,” Eisenberg recalls, but the researcher highlights the chemical compounds found in pesticides and even hygiene products that interact with the endocrine system. “These chemicals, which are endocrine disruptors, are in both our environment and our diet,” he points out. “When we change the constitution of our body, it also affects our hormonal environment,” he adds.
