Latest research report have shown that  men who wear light boxers or loose underwear are more likely to easily make babies than men who wear tight boxers.

 Harvard TC Chan School of Public Health in Human Reproduction, tight-fitting underwear leads to reduction in sperm concentration and can also result in lower blood levels of follicle-stimulating hormone (FSH).

Nigerian men, you realise sometimes you just want to walk about naked or just tie wrapper, that’s because you body can’t handle it, some do boxers all day though.

An important strength of this study is that we were able to investigate the potential relationship between the type of underwear worn and indicators of testicular function such as reproductive hormone levels and DNA damage, which were missing in all previous studies on the topic.
Because of this, we were able to find a potential compensatory mechanism whereby decreased sperm production relating to the type of underwear signals to the hypothalamus to increase secretion of gonadotropin[s], [hormones that act] on the testes and that is reflected by the increased levels of FSH, to try to increase sperm production.

On this study, by analysing 1,186 sperm samples from 656 different men who were seeking fertility treatment at the Massachusetts General Hospital between the years 2000 and 2017. In this number, 304 men also had a blood sample taken so that physicians could study their levels of FSH, estradiol (a form of estrogen) and luteinizing hormone (a hormone used in reproductive cell development).

They found that the men who wore loose boxers, which made up 53 per cent of the group, had a higher sperm concentration of 25 per cent, a higher sperm count of 25 per cent and lower FSH levels of 14 per cent than those who worse tighter items of underwear. And yes for proper control, factors that could influence the sperm like age, BMI, smoking history and reported time between the sample and last ejaculation were all adjusted accordingly.

At this point, we would recommend wearing boxers or looser underwear compared to tighter underwear since it is a modifiable lifestyle that could easily improve the semen quality of the men – Dr. Minguez-Alarcon
