Describe the male reproductive organs of man.

Male reproductive organs: Reproductive system of male human body consists of the following organs:
(a)    Testes (Sex glands): There is a pair of oval testes present in the scrotum. 
(b)    Epididymis: It is the portion which is closely attached to the posterior side of each testes. It receives and stores the sperms produced by the testes.
(c)    Vas deferens: From each epididymus a tube of whitish colour arises. The tube is known as vas deferens. The sperms pass through it.
(d)    Seminal vesicle: The epididymus is connected by the seminal vesicle by vas deferens. The seminal vesicle are a pair of small lobulated sacs situated at the base of urinary bladder above the prostrate gland. They join each other to form ejaculatory duct. Seminal vesicles secrete a viscous fluid which forms most of the part of semen. It also lubricates the passage through which the sperms travel. This fluid also protects the sperms from the acids normally present in the urethra and female reproductive duct.
(e)    Prostrate Gland: It is a bilobed glandular mass embracing the urethra. In man two prostrate glands fuse to form only one. It produces prostatic fluid which is discharged into urethra through more than two dozen fine ducts. There is more secretion during sexual act when they are forcefully ejected by contraction of muscular and elastic tissues.
(f)    Urethra: It is a tube starting or arising at the urinary bladder. It passes through the copulatory organ (penis) to the tip of the glands penis. The urethra of male functions both for the passage of sperms and urine.
(g)    Penis: The penis is the copulatory organ of male for the transfer of the sperms to the female reproductive tract.
