Male reproductive system
|Male reproductive system|
|Latin||systema genitale masculinum|
The male reproductive system is made up of a number of sex organs. It works in the process of human reproduction. Some organs are outside the body, some are in the pelvis. The main male sex organs are the penis and the testicles, which produce semen and sperm. During sexual intercourse the penis delivers the sperm into a woman's body. The sperm can fertilize the egg cell in the woman's body. The fertilized egg will develop into a fetus, which is later born as a baby.
The matched system in woman is the female reproductive system.
sex organs[change | change source]
The penis is an organ that is used for urination and sexual intercourse. The urethra is a passage runs underside of the penis. The urine and the semen are released through the urethra. When the male becomes sexually aroused, the penis becomes hard and bigger and ready for sexual intercourse. This erection occurs because the erectile tissue of the penis is filled with blood.
Testicles produce sperm cells. From teenage years to senile years, the partially ferrous tubes are in regular production of sperm cells. These cells are very vital when it comes to reproduction. The cells are produced by the testicles, which are externally located. When the sperms are produced, they are provisionally accumulated in the epididymis which is connected to the partially ferrous tubes.
Testicles are also referred to as the gonads and they play a very vital role when it come sexual activities. They are used to establish and preside over the manliness of a person. This is very different when it is compared to the secondary characteristics of a man. These characteristics include the beards, breaking of voice (deep voice) heavy bones (masculinity) and constricted pelvis that in charge of producing offspring. When the testicles are removed, male secondary characteristics are likely to be interfered with.

Seminal vesicle: The sperms are later moved to the seminal vesicle passing through a lengthy thin duct. The seminal vesicle then produces a thick substance that aids in the conservation of the sperms before they are finally released.
Infertility in Men - Male Reproductive Disorders[change | change source]
Most causes of infertility in men is as a result of male reproductive system disorders. An abnormal penis may not be able to deliver the semen properly. In hypospadias or epispadias where the opening of the penis is in an abnormal position, male infertility is a possibility.
Other factors in male infertility[change | change source]
Varicocele: This is a condition characterized by enlargement, elongation and coiling of the blood vessels around the scrotum. Most times, it appears as bag of warm in the scrotum. It is seen in 10% of normal males and 40% of males with infertility.
Irradiation like X-ray, GSM etc. triggers release of free radicals and can directly halt the Spermatogenesis (process of sperm formation). This is the reason behind covering the scrotum (Testes) during X-ray.
Autoimmune Antibodies: It has been found that some people have antibodies (defense chemicals) against their own sperm cells. By this interaction, the antibodies destroy the sperm cells leading to Azoospermia, oligospermia or normospermia depending on the degree of damage. This condition can be treated if diagnosed.
Liver disease: The liver is a vital organ which ensures that the male hormone (testosterone) dominates in action than female hormone, oestrogen. This it does by breaking down the oestrogen continually. However in a case of liver disease which may impair liver functions, the level of female hormone, oestrogen, increases leading to male characteristics, loss of pubic hair and impotence.
