4 Factors That Causes Male Infertility

What are the causes of male infertility? Is there a maximum age limit that affected male infertility?


Actually, until old age, man can still produce sperm. But there are limits. At the age of 40 years and above, the movements of the sperm already begun to slow down. So if there was a couple who difficult to have a child, not because there is "something wrong" with the wife, but men can also contribute to infertility.

To find out what are the cause of male infertility, it is necessary to conduct medical check-up. The doctor will check your overall fertility rate, such as basic check-up (hormones, sperm analysis, and immunological factors). In addition, genetic factors also can be a cause of male infertility.

4 Factors That Causes Male Infertility

Then, what are the causes of male infertility?


There are 4 factors that you should know :

1. Pre-testicular factor is about 15%

  • Sexual disorder such as premature ejaculation.

  • Disorders of the hormones that regulate the formation of the testes to produce sperm, such as FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone). These hormones are produced in the brain bottom. Disorders of the brain and glands that form the hormones that cause the testicles to be less good in producing sperm.

  • As a result of drugs or alcohol. The chemicals in these drugs cause a gene that works as a recipient of testosterone do not develop. As a result, the gene can not receive the hormone testosterone, so it can not produce sperm.


2. Testicular factor is about 25%

  • Disorders of the testes, such as mumps can make testicular damage and disruption in producing sperm.

  • Gen recipient of testosterone did not develop so that the hormone does not produce sperm.

  • Environmental exposure to lead or radiation. One of these disorders is a varicocele. A varicocele is a widening of the veins around the testes. This occurs because the blood that should be brought back to the heart to be cleaned, but most of it back again to the testicles. In fact, the dirty blood back to the testicles will weaken the sperm for their dirty substances. This condition will make the temperature in the testicles will increase, thereby overheating and affect sperm quality.


3. Post-testicular factor is about 26%

  • Interference or obstruction of the testis. So, although the testicular and hormones are good, but due to the blockage then the sperm still can not be produced by the well.

  • Internal factors, such as disorders of the testosterone which causes decrease libido.

  • External factors, such as psychological trauma, causing difficult penetration.


4. Unexplained infertility is 32-39%

  • Many cases of infertility can not be explained. If all the tests of your fertility and your partner are good but still difficult to conceive, you both may experience unexplained infertility.


How many normal sperms required for fertilization?


Actually, it only takes one sperm to get conception. But why is still not pregnant?

A study has used the method HOPE (Hamster Oocytes Penetration test), which put the hamster as experimental animals. From experiments with the hamster,  it is known that the number of sperm cells to fertilize the egg is above 1 million/ml.

HOPE of the test is also known, the human sperm count of less than 5 million/ml was still able to fertilize the egg. If the number is below 3 million/ml, pregnancies occurred about 1,7%. And if the sperm count below 1 million/ml, the ability to fertilize the egg is only about 0,7%.

Other disorders that often occurs is Azoospermia. This disorder is characterized by permanent discharge of sperm but is does not contain sperm cells at all. The reason is could be due to hormonal disorders, bacterial infection, or injury to the blood vessels that carry sperm cells.

To cure male infertility, you can immediately meet your doctor and do an intensive check-up and treatment.
