For men looking to enhance their sperm count, a new study suggests embracing the Scottish cultural heritage of doning a kilt. Or at least, go commando and skip underwear altogether, the researchers say.
In addition to keeping their scrotum at a cooler temperature, which research proves can boost sperm count, kilt wearers enjoy psychological benefits, such as feeling more masculine and proud and enjoying positive attention from sexual admirers, reported LiveScience on April 19. The research, based on analysis of prior studies, was published in the latest issue of the Scottish Medical Journal.
A study published last year in the journal Human Reproduction found that men with fertility issues should avoid tight-fitting underwear to enhance sperm count. Experts have also warned that wearing skinny jeans could reduce sperm count while increasing risk for testicular problems.
Laptop computers with WiFi have also been found to damage sperm, according to a study published in 2011 in the journal Fertility and Sterility.
But that's not all: a small Italian study published last month also suggests that saunas may lower sperm counts, but the effect is just temporary. That study appears in the journal Human Reproduction.
