◆ The testes also produce the male sex hormone testosterone.
◆ The testes of man produce sperms from the age of puberty.
✿ Scrotum:-
◆ The scrotum is a pouch of skin that hangs between the legs. It is divided internally into right and left scrotal sacs by a muscular partition.
◆ The scrotum acts as thermoregulation and provides an optimal temperature for the formation of sperms.
◆ During summers, when temperature rises, the scrotum becomes relaxed to lose heat.
✿ Vas Deferens:-
◆ This is straight tube, about 40 cm long, which carries the sperms to the seminal vesicles.
✿ Urethra:-
◆ It is about 20 cm long tube that arises from the urinary bladder to carry urine.
◆ It runs through the penis and opens to the outside through male genital pore.
◆ The urethra carries urine from the bladder, as well as sperms from the vas deferens, through the penis.
