Male reproductive system

The male reproductive system consists of the following parts:

1. Testes: These are a pair of small-sized, oval-shaped, pinkish colored structures present in a thin-walled skin pouch called scrotal sac or *******. It protects the sperms against relatively high body temperature.
2. Epididymis: Epididymis is about 6 metres long highly coiled tube present on the superior pole of each testis.
3. Vasa deferentia (Seminal ducts): A vas deferens is a long, narrow tubular structure which starts from the tail of the epididymis
4. *****: It is a long cylindrical, erectile copulatory organ. It forms the external genitalia of males. The tip of the ***** is highly sensitive and is known as the glans *****.
   Accessory *** glands of male: These include a pair of seminal vesicles, a prostate gland and a pair of Cowper or bulbourethral glands. 
   The urethra also has mucus-secreting glands in its lining.
   Semen or seminal fluid: The secretion of accessory *** glands and mucus are added to sperms to form seminal fluid or semen.
