As described in thisvideo, a vasectomy is a procedure in which a small sectionof the ductus (vas) deferens is removed from the scrotum.This interrupts the path taken by sperm through the ductusdeferens. If sperm do not exit through the vas, eitherbecause the man has had a vasectomy or has not ejaculated,in what region of the testis do they remain?arrow_forward
