Infertility is diagnosed after a year of attempting a pregnancy without success, but perhaps the problem is him and not you. Male infertility affects between 20% and 70% of men in different parts of the world, according to a study published in reproductive biology and endocrinology. The first step to treat this condition become pregnant is to identify the cause of infertility.
Causes of male infertility
Infertility in the male is given by problems in sperm production or transfer of sperm from the testicles to their final destination. Continue reading below about the causes and conditions leading to male infertility:
|Problems in the production of sperm||-Chromosomal or genetic causes.
– Undescended testicle
-Twists in the scrotum
-Side effects of drugs and chemicals
|Blockage in the sperm transport||-Infections
– Diseases of the prostate
– Absence of the vas deferens conductors
(ejaculation and erection)
|-Ejaculation or retrograde
-Lack of ejaculation
-Damage to the nerves
-Side effects for medications
|Hormonal problems||-Pituitary tumors
-Congenital absence of the follicle hormone estradiol
– Anabolic steroid abuse
|Antibodies against sperm||-Injury or infection of the epididimis
The ideal sperm
The male reproductive cell, sperm, has several features needed to reach an egg and fertilize it successfully:
Amount. Whenever your partner ejaculates releases sperm-laden semen. The average range is between 40 million and 300 million sperm per milliliter of semen, and less than 10 million amounts are considered to be deficient.
While the numbers are exaggerated, that amount is required because, on average, only 15% of the sperm have the ability to fertilize the egg, those only 400 survive the stress of the orgasm and ejaculation, and approximately 40 support the toxicity of the semen and the hostile environment of the vagina. The sperm that manage to enter the cervical neck must survive several days to reach the fallopian tubes fallopian, and in the end, only one manages to penetrate the protective coating of the egg to start a pregnancy.
Motility (movement). Motility is the ability of the sperm move and advance by the female system. Despite the millions of sperm in each ejaculation, only 40% are mobile. The speed and direction with which to move sperm determine its ability to achieve the goal.
Morphology (shape). A sperm requires a specific structure to overcome the barriers and fertilize the egg. The sperm body has three parts: an oval head that contains the DNA, segment means that allows the movement, and the tail that moves sideways in whip to drive to sperm.
Diagnosis of male infertility
If you and your partner met a year trying a pregnancy without results, it is appropriate to start fertility in both studies. In the case of your partner, this includes:
- Semen analysis. Study of the number, shape and motility of the sperm in the semen.
- Physical examination, including family history, and questions about his health, sexual life and habits. A physical examination may reveal the presence of varicoceles, which are inflammation of the veins in the testicles.
- Hormonal evaluation. A blood test can determine if your partner is hormonal levels necessary for sperm production.
