Wearing loose clothing, such as Scottish kilts, may boost sperm count, a new study published in the Scottish Medical Journal reveals.

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.
