Does bike riding, tight underpants, or wearing underpants to bed reduce testosterone levels?
 
Effect of different types of textile fabric on spermatogenesis: an experimental study.

This was a study on synthetic or cotton undergarments on dogs and it showed a response to synthetic undergarmnets in reducing spermogenisis, not test per se.

Effect of scrotal insulation on the ability of ram testes to produce testosterone in vitro.

Does show a reduction in overall amount of production when testicle temperature is elevated.

Several studies based on scrotal temperature show that temperatures are elevated by a multiple of factors, including insulating material, tightness of material, sitting postion, exercise mode (walking, standing, running raise scrotal temp less than sitting exercises DUH). So if scrotal temp is elevated and elevation does hampen test production you might want to Joan of Arc it, you know let the FREE FLAG FLY, just let me know where you ride so I won't go anywhere near there.
