Some doctors blame tight jeans for a syndrome called meralgia paresthetica (skinny jean disorder).

My old room mates dr told him his jocky shorts warmed his testicles and impeded sperm growth
he switched to boxers and his wife got pregnant
Holy Mac! I’ve had meralgia parenthetica for years, but I don’t wear tight jeans. Maybe I just need more room than most.
