Doctor's answer:
Hello, medical research shows that the factors or causes of infertility account for 1/3 in men and 1/3 in women, with the remaining 1/3 being cases where both men and women are abnormal. Male infertility can be categorized into ten points:1. Testicular Abnormalities
Testicular abnormalities can occur in three ways:
① Cryptorchidism: This not only leads to infertility but can also induce malignancy. Unilateral cryptorchidism causes infertility in 30%-60% of cases, while bilateral cryptorchidism causes it in 50%-100%.
② Damage to the primordial germ cells during fetal development due to adverse environmental factors.
③ Early testicular injury, which can be caused by birth trauma during delivery.
2. Chromosomal Abnormalities, such as:
- Intersex
- Abnormal development of reproductive organs
3. Postnatal Testicular Injury, such as:
- Injuries to testicular blood vessels caused by hernia repair surgery, hydrocele surgery, or testicular fixation surgery, which obstruct blood supply and lead to testicular atrophy.
4. Hydrocele
Hydrocele compresses testicular blood circulation, which can lead to testicular infection or atrophy. The incidence rate of this condition after puberty is 16%-19%.
5. Gravitational Effects
Excessive physical load can reduce intratesticular sperm production, leading to infertility.
6. Psychological Factors
Abnormal psychological states in patients can disrupt the neuroendocrine system, leading to low sperm production or sexual dysfunction, resulting in infertility.
7. Blood Supply Obstruction
Patients with arteriosclerosis or diabetes often have testicular arteriopathy, which can impair sperm production and cause infertility.
8. Substance and Medication Effects
Excessive intake of substances such as nicotine, alcohol, or opium can affect sperm production. Antiepileptic drugs also have a direct impact on spermatogenesis.
9. Environmental Factors
- Miners or boiler workers working in excessively hot tunnels
- Tight underwear
- Excessive smoking or drinking
- Hypoxia conditions
All of these can affect fertility.
10. Reproductive Organ Infections
Infections caused by bacteria, viruses, or protozoa can directly damage the testicles, severely impairing spermatogenesis and reducing sperm viability, leading to infertility. For example, 20% of cases of mumps before puberty develop orchitis, resulting in infertility.
