Here are some...: We are not born equal in any parts of the body. Specifically for the sac, its tying-up or sagging-down is related with the contraction & relaxation of cremasteric muscles in response to environmental temperature or personal physical straining; its wrinkling may worsen with aging but most noticeable with outside temp... However, such expected normal change bears no direct relation with function.
