The vas deferens is a muscular tube that transports mature sperm from the epididymis to the urethra during ejaculation. Each male has two vas deferens tubes, one connected to each testicle.
These tubes contract during ejaculation, pushing sperm toward the urethra where they mix with fluids from the seminal vesicles and prostate gland to form semen.
Blockages or damage to the vas deferens can prevent sperm from reaching the ejaculatory pathway. Such blockages may occur due to infections, surgical procedures, or congenital abnormalities.
One condition involving absence or blockage of the vas deferens is Congenital Bilateral Absence of the Vas Deferens.
This condition is often associated with genetic mutations and erotic may lead to infertility if untreated.
