Male reproductive system
The male reproductive system consists of the penis, scrotum, testicles and a variety of the interior glands like the prostate. All these bodies' parts are very important when it comes to the normal functioning of the body. Each one of them has a different role to play.
- Testicles: they 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.
- 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.
- Intestinal cells: these cells are mainly used in the production of the testosterone which flows into the blood streams and establish the secondary individuality of a person. When the sperms are produced, they are provisionally accumulated in the epididymis which is connected to the partially ferrous tubes. These 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.
- Urethra: this is a passage that is used in the removal of the urine. Prostate glands that are located here then produce a thick substance which facilitates the conservation and transportation of the sperms which are now referred to as the semen.
- Penis: it has glands that secrete a base that counterbalances any urine that might be harmful to the sperm cells. The penis is an organ that is used in the placing of the semen into the female reproductive tract during sexual intercourse. This is facilitated by the increase volume of blood into the penile tissues.
Infertility in Men - Male Reproductive DisordersEdit
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 are discussed below:Edit
1) 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.
3) 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.
4) 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.
5) 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.
