Patient's question:
I got married a year ago and haven't had children yet. I went to the hospital for a check-up. The woman's examination results were normal, but the man was found to be infertile.Doctor's answer:
Main Causes of Male Infertility:1. Male reproductive tract infections: Epididymitis, severe prostatitis, viral infections, etc.;
2. Abnormal semen: Azoospermia (no sperm), oligozoospermia (low sperm count), necrozoospermia (dead sperm), asthenozoospermia (weak sperm), and semen nonliquefaction, etc.;
3. Spermatogenesis disorders: Such as varicocele, congenital testicular dysgenesis, cryptorchidism, orchitis or testicular atrophy, and endocrine diseases, all of which can reduce sperm quantity, decrease motility, or cause sperm deformities, leading to infertility;
4. Ejaculatory obstruction: Lesions in the epididymis, vas deferens, ejaculatory duct, or urethra can hinder semen discharge, clinically often obstructive azoospermia, directly affecting male fertility;
5. Ejaculation disorders: Such as erectile dysfunction, genital malformations, or trauma preventing sexual intercourse, as well as premature ejaculation or retrograde ejaculation, where semen cannot enter the female reproductive tract or fertilize an egg;
6. Substance-related effects: Certain substances may cause temporary or permanent reductions in sperm count, such as androgen preparations, antimicrobial agents, or antitumor drugs, all of which can impair male fertility;
7. Other factors: Systemic diseases, psychological factors, chromosomal abnormalities, and unhealthy lifestyle habits (e.g., smoking, alcohol consumption, frequent hot baths) may also contribute to infertility.
