Patient's question:
When we were planning to have a child, my husband was diagnosed with blocked vas deferens and azoospermia. His blood tests were normal, and the testicular biopsy was also normal. We don't know what factors or causes could have led to this.Doctor's answer:
Factors or Causes of Infertility1. Congenital Abnormalities: Absence of the head and body of the epididymis in males, partial or complete absence of the vas deferens, and disconnection between the epididymis and vas deferens. Additionally, developmental abnormalities of the epididymis and vas deferens, or incomplete development of the seminal vesicles.
2. Infections: Infections of the urinary and reproductive systems, which are one of the factors or causes leading to vas deferens obstruction. Male friends suffering from epididymitis, prostatitis, seminal vesiculitis, or epididymitis and vas deferens tuberculosis may experience vas deferens obstruction.
3. Trauma: If the scrotum or perineum of a male is injured, it can damage the epididymis and vas deferens, leading to partial or complete rupture of the ducts. Even healed scars can affect sperm passage, resulting in male infertility.
