For many, there is a myth for others to be assured: how much male underwear affects fertility or quality of semen? According to a study published in the Human Reproduction specialist magazine, you can use tight or tight pants to reduce the quality of semen, affecting its concentration.
Researchers Harvard University The conclusion was found that the men who are they wear wide underwear get sperm concentrations higher than others, after analyzing the results of 656 participants.
Lidia Mínguez-Alarcón's scientist led by the team also found that men who wore the weights The box type had lower levels of the follicle symbylol hormone (FSH), which stimulates sperm production.
The researchers ensured these perceptions "They suggest that FSH goes when it needs to compensate for damage by the horse by increasing abrasive temperatures and sperm concentration."
Mínguez-Alarcón chose her male colleagues who They were looking for fertility treatment at the Massachusetts General Hospital between 2000 and 2017. They were between 18 and 56 years old, with an average physical mass index (BMI), and had not had vasectoms.
All of them provides a sample of semen and a blood sample on the same day and answered a questionnaire asking for a style of underwear that they wear most often in the previous three months. Among the 656 men, 53% said they generally wore wider spans.
What were the measurements?
Those who used mainly used clothing were used:
– a 25% higher sperm volume;
– a percentage of 17% higher in total sperm;
– and 33% more sperm in individual ejaculation.
The biggest difference in sperm concentration has been seen among men who wear more boxing snacks and those who wear tight subscriptions regularly. "We could find that the body is trying to compensate for the production of low sperm by signaling the hypothalamus to increase the secretion of gonadotropin, a hormone that is acting on the test," said the report.
