无精子症 中国就医指南

Azoospermia is a male infertility condition defined by the complete absence of sperm in the ejaculate, confirmed by centrifugation and microscopic examination of at least two properly collected semen samples. It affects approximately 1% of all men and accounts for 10–15% of cases among infertile males. Azoospermia is not a disease per se but a clinical sign with diverse underlying causes, broadly categorized into obstructive azoospermia (OA) and non-obstructive azoospermia (NOA). In OA, sperm production is normal but blocked due to anatomical disruptions—such as congenital bilateral absence of the vas deferens (CBAVD), prior vasectomy, infection-related scarring, or ejaculatory duct obstruction. In NOA, spermatogenesis is impaired due to genetic abnormalities (e.g., Klinefelter syndrome, Y-chromosome microdeletions, CFTR mutations), hormonal dysregulation (hypogonadotropic hypogonadism), testicular failure (e.g., cryptorchidism, orchitis, chemotherapy/radiation exposure), or idiopathic causes. Risk factors include childhood mumps orchitis, undescended testes, gonadotoxic treatments, obesity, chronic systemic illness, environmental toxin exposure (e.g., pesticides, heavy metals), and lifestyle factors such as smoking, excessive alcohol use, and prolonged heat exposure. Importantly, azoospermia is asymptomatic—men typically present with infertility rather than physical symptoms; sexual function, libido, and secondary sex characteristics are usually preserved unless associated with endocrine disorders. Diagnosis requires comprehensive evaluation: detailed history and physical exam, serum hormone testing (FSH, LH, testosterone, prolactin, inhibin B), genetic screening (karyotype, Y-microdeletion analysis, CFTR testing when indicated), and scrotal ultrasound. In select cases, testicular mapping biopsy or microdissection testicular sperm extraction (micro-TESE) may be performed to assess sperm presence and retrieve viable sperm for assisted reproduction. Psychologically, azoospermia profoundly impacts quality of life—triggering distress, diminished self-esteem, marital strain, social withdrawal, and depression. Cultural expectations around masculinity and fatherhood intensify emotional burden, particularly in societies where biological parenthood carries high sociocultural weight. While not life-threatening, untreated azoospermia can lead to long-term psychosocial morbidity and relationship dissolution if reproductive goals remain unmet. Early referral to a reproductive urologist or reproductive endocrinologist is critical to differentiate OA from NOA, guide appropriate intervention, and optimize fertility outcomes—including surgical sperm retrieval combined with intracytoplasmic sperm injection (ICSI), which enables biological fatherhood in up to 60% of NOA cases and nearly all OA cases.
