What are the most common causes of infertility?

There are numerous factors which can account to retrograde ejaculation including damage to the spinal cord, previous surgical procedures and diabetes.

If any of these tubes are blocked, it may lead to low sperm count and as a consequence, infertility. Deformities or a total absence of the vas deferens is one of the foremost reasons for sperm blockage and can be a congenital disability or due to physical trauma. Other tubules which might cause blockages include the epididymis, the urethra and the ejaculatory ducts. Previous surgeries, infections and cysts are some of the common reasons for abnormalities within the tubules.
