Human Male Reproductive System- Organs, Structure, Functions
A male reproductive system is a group of organs and hormones that play a role in human
reproduction. These organs and hormones are present either inside or outside the pelvis.
Organs of the Male Reproductive System
Two testes
Two epididymides
Two different ducts (vas deference)
Two spermatic cords
Two seminal vesicles
Two ejaculatory duct
A prostate gland
A penis
, Structure of the Male Reproductive System
The testes, epididymides, and the testicular ends of the spermatic cords are present in the
scrotum. A scrotum is a pouch-like structure that consists of fibrous connective tissues and
smooth muscles. It is divided into two compartments, each of which contains one testis.
Testes
In birds and mammals, a pair of testes are present on either side with the left one a bit
larger than the right one. In the case of sharks, however, the right one is larger than the
left one.
A single testis is present in primitive jawless fish through the midline of the body which
forms after the fusion of paired structures in the embryo.
The testes are the male reproductive glands that are about 4.5 cm long, 2.5 cm wide and
3 cm thick and surrounded by three layers of tissues namely, tunica vaginalis, tunica
albuginea, and tunica vasculosa.
A testis is composed up to 900 coiled seminiferous tubules in which the sperms are
formed. In the case of amphibians, however, seminiferous tubules are absent, and the
sperms are present inside a structure called sperm ampullae.
Between these tubules are interstitial cells or Leydig cells which produce the hormone
testosterone after puberty.
The seminiferous tubules are folded and tightly packed to form the epididymis which
comes out of the scrotum in the form of vas deference.
