Performing isometric contractions of the abdominals is often promoted as a way to develop these muscles. However, anecdotally speaking, it has the undesirable effect of pulling the scrotum up towards the body. I wonder, will this form of muscle development permanently cause undesired effects?
Undesirable effects on the scrotum? Sperm maturation?
Specifics?
Welcome aboard.
To sum up: No.
Ok, more specifically, will it cause increased muscle tone, which in effect will cause the scrotum and testes to remain in this “retracted” (for lack of a better term) position. Are the muscles of the abdomen connected to something in the scrotum?
To sum up again: No
