Wearing loose clothing, such as Scottish kilts, may boost sperm count, a new study published in the Scottish Medical Journal reveals.
Analyzing previous studies on the subject, the researchers found that wearing loose clothing cooled down the scrotal area and improved the sperm count.
The researchers also said that wearing kilts provided psychological benefits including a feeling of masculinity and pride as well as positive attention from the opposite sex.
"Based on literature on scrotal temperature, spermatogenesis [or the process of sperm development] and fertility ... men who regularly wear a kilt during the years in which they wish to procreate will, as a group, have significantly better rates of sperm quality and higher fertility. There are strong psychological benefits associated with kilt wearing, most notably (a) a feeling of masculinity and pride and (b) positive attention from sexual admirers", the researchers said.
