I seem to remember, (photo memory anyone), a study which correlated sperm motility to heat.

It was reported that men who wore boxer style underwear had a more ventilated scrotal area and high sperm motility.

Conversely men who wore jockey shorts were less jocular, (Jock_error). ((pun for the day))

I wonder if a combining of the two data sets will provide some pregnant knowledge!

Kilts, anyone?
