Does too high scrotal temperature affect sperm count? Explain the six major causes of oligospermia

Oligospermia refers to a disease in which the number of sperm in semen is lower than that of normal fertile men. Male infertility caused by oligospermia accounts for a large proportion of infertility. I believe that many people know about the etiology of oligospermia, but it is not complete. Here is a detailed introduction, hoping to arouse enough attention.

Explain the five causes of oligospermia

1. Testis

In addition to the degeneration of the convoluted tubules affecting the production of the testis, the complete reduction of the testis on the other side may also have a certain degree of damage. The effect of antisperm antibody produced by testis on normal testis may be the reason.

2. Endocrine abnormality

The normal mental function of men depends on the normal function of the hypothalamus-pituitary gonadal axis, and any part of the disorder will affect the mental function. Thyroid and adrenal diseases will also affect the gonadal function, and sperm disease will be reduced.

3. Autoimmunity

Studies in reproductive immunology have shown that male autoimmunity affects fertility, and anti-sperm antibodies affect sperm production and transportation.

4. Varicocele

Infertility caused by varicocele accounts for 30%~40% of male infertility. Due to the rise of testicular temperature and toxin accumulation, the spermatogenic function of testicles is affected, resulting in oligospermia, and in severe cases, azoospermia. The symptoms of varicocele are not obvious at the beginning. People in serious condition feel that the scrotum is swollen, and there are earthworm-like blood vessels on it. Semen examination showed that the number of sperm decreased, the activity was poor, and the number of abnormal sperm increased.

5. High scrotal temperature

The seminiferous tubules in the testis that produce sperm are very sensitive to temperature changes. The temperature of this part is 2~3 ℃ lower than the human body temperature. Too high temperature can easily inhibit the survival and maturation of sperm, and the number of sperm in the semen is reduced or the activity is decreased. Therefore, male friends should wear less tights, wash less sauna, avoid electromagnetic radiation and high temperature, and develop good living habits.

6. Inflammation of genitourinary system

Patients with orchitis, orchitis, seminal vesiculitis, prostatitis and urethritis have the highest proportion of oligospermia. Urogenital tract inflammation directly affects the spermatogenic function of testis, produces anti-sperm antibodies in blood and semen, affects the acidity and alkalinity of semen, plus the direct killing effect of pathogens on sperm, resulting in decreased sperm.
