main parts of the male reproductive system

male reproductive system- testes are the oval-shaped organs that lie outside the abdominal cavity of a man. numbers of testes of man are two. it makes sex cells (sperms) and sex hormones called testosterone. Testes make sex gametes or sperms throughout his life.


the testes of a man lying in the small muscular pouch called the scrotum. It outside of the abdominal cavity.


The sperms formed in the testes come out and go into a coiled tube called the epididymis. The sperms get stored temporarily in the epididymis.

From the epididymis, the sperms are carried by a long tube called vas deferens which joins with another tube called the urethra coming from the bladder.

Along the path of vas deferens, the glands called seminal vesicles and prostate gland add their secretion to sperms so that the sperm is now in a liquid. The urethra forms a common passage for sperms and urine.

Penis: The urethra carries the sperms to an organ called the penis which opens outside the body.

how is sperm produced and released:

Semen vesicles, secrete mucus and nutrients (such as fructose) into the ejaculatory duct. The single prostate gland exhibits a milky, alkaline fluid that increases the pH of semen. At the base of the erectile tissue of the penis is the third pair of gallopers, called Cowper glands, that contribute more mucus to the fluid in the seminal fluid.

The resulting fluid contains glucose and fructose that are metabolized by sperm for energy, acid-base buffers to protect the sperm from acidic secretions of the vagina, and mucous contents that lubricate the pathways through which sperm travel.

A male has a male sex cell (sperm), And a female sex cell called ova (eggs). Sexual reproduction is a combination of specialized reproductive cells called sex cells. Sex cells are also known as gametes. There are two types of gametes, Male gametes, And female gametes. The male gametes are called sperm and the female gametes are called ovum or egg.

Semen, contain seminal fluid and sperm.  There are three pairs of glands that together contribute to pro­duce the 2 to 5 ml of seminal fluid per ejaculation. These are,
  1. The paired seminal vesicles, 
  2. The prostate gland, 
  3. And Cowper's glands. 


ovum or egg (female gametes)  is round and about 0.15 mm in diameter. The ovum is a single cell having a nucleus, cytoplasm, and cell membrane.

sperm  (male gametes)  is about  0.05 mm long. Sperm has a head, a middle piece, and a tail. A sperm is a single cell with a nucleus, cytoplasm, and cell membrane.
