Analysis of Several Etiological Causes of Dead Semen Disease: Prevention of Dead Semen Should Pay Attention to Premarital Physical Examination
For a man, once he suffers from azoospermia, it is a very painful thing and needs to be treated as soon as possible. What is necrospermia? Simply put: The number of sperm in semen is too small! According to the International Health Organization, if the number of sperm per milliliter is less than 20 million, it is considered azoospermia. Of course, the degree of azoospermia can also be divided based on the number of sperm, and what happens if one suffers from azoospermia? In severe cases, it can lead to infertility! The beginning of fertility comes from the union of sperm and egg. Dyospermia is a condition where the sperm content is too low, which naturally reduces the chance of conception. So what are the symptoms of azoospermia?
What are the causes of azoospermia?
Infection
Acute and chronic inflammation of the genital tract or reproductive glands such as the epididymis, vas deferens, seminal vesicles and prostate can reduce sperm motility. The influence of infection on sperm motility can be multifaceted. These come from the direct action of microorganisms on sperm.
In addition, mycoplasma can be adsorbed on the head, middle and tail of sperm, so that when the sperm moves forward, the hydrodynamic resistance increases and the movement speed slows down, affecting the sperm motility and the ability to penetrate the egg cell. Mycoplasma produces NH3 during its growth process, which has a direct toxic effect on sperm.
Abnormal semen liquefaction
Non liquefaction or high viscosity of semen is one of the causes of male infertility, and a very important factor may be affecting the motility of sperm, leading to infertility. Long and slender fibrin can be seen in the non liquefied seminal plasma and interweave with each other, reducing the space for sperm activity. Sperm is restrained, and coarse fibers are also seen to be connected into a network by many fine fibers. These may be the reasons for mechanical restriction of sperm forward movement, leading to azoospermia.
Immune factors
Anti sperm antibodies can affect sperm fertilization function through several different pathways. The impact on sperm motility may be due to the binding of AsAb to the tail of sperm, which hinders sperm motility, reduces motility, and has poor penetration ability. This has been confirmed by the significant decrease in the ability to penetrate cervical mucus when anti sperm antibodies are present at the tail of sperm.
Endocrine factors
Endocrine hormones not only play a role in the occurrence and maturation of sperm, but also affect their motility. Excessive testosterone in seminal plasma may inhibit sperm motility.
Kartagner's syndrome
Kartagener's syndrome is a congenital lack of ciliary structure, which is manifested by the inability of cilia of ciliary cells in the body to move, mainly the absence of ciliary dynein arms of peripheral microtubules.
Chromosome abnormalities
The autosomal and sex chromosome aberrations not only affect the number of sperm, but also affect the viability and forward movement of sperm. It is known that ultrastructural devices related to sperm motility can cause abnormalities in sperm tail structure due to genetic factors,
Varicocele
Varicocele can lead to male infertility in many ways. It not only affects the occurrence of sperm, but also reduces sperm motility. The mechanism may be due to blood retention in varicose veins, microcirculatory disorders, nutrient deficiency, decreased oxygen partial pressure, insufficient energy generation, and endocrine dysfunction. In addition, it may also be that varicocele leads to the production of autoimmunity, such as antisperm antibodies, and mycoplasma infection indirectly causes the decline of sperm motility.
How to prevent azoospermia?
1. Vaccination should be administered on time and good personal hygiene habits should be maintained to prevent various infectious diseases that harm male fertility, such as mumps and sexually transmitted diseases.
2. To master a certain level of sexual knowledge, understand male physiological characteristics and health knowledge. If you find testicular changes that are different from usual, such as swelling, hardening, unevenness, pain, etc., it is necessary to promptly diagnose and treat.
3. If you frequently come into contact with radioactive substances, high temperatures, and toxins, you must strictly follow the operating regulations and protective regulations when operating. Do not be careless. If you want to have children in the near future, it is best to leave such work for six months before giving birth.
4. The testicle is a very delicate organ, and its optimal working temperature should be about 1 degree lower than the human body temperature. If the temperature is high, it will affect the production of sperm. Therefore, any factors that can increase the testicular temperature should be avoided, such as prolonged cycling, hot baths, and wearing jeans.
5. Change bad habits, quit smoking and alcohol; Don't eat anything too greasy, otherwise it will affect your libido; In addition, it is important to avoid contact with toxic substances in daily life, such as clothes taken from dry cleaners that need to be left for a few days before wearing, as dry cleaners can affect male sexual function.
6. Attention should be paid to pre marital physical examinations, and early detection of abnormalities can avoid the pain after marriage. After getting married, it is important to regularly communicate with your wife about the problems encountered in sexual life, cooperate and understand each other, so that many mental impotence or premature ejaculation can be avoided.
