Damaged Sperm Ducts

Seven percent of infertile men can not transport sperm from their testicles to out of their penis. This pathway may be blocked by a number of conditions:
1) A inheritable or experimental mistake may block or beget the absence of one or both tubes (which transport the sperm from the testes to the penis).
2) Scarring from tuberculosis or some STDs may block the epididymis or tubes.
3) An optional or accidental vasectomy may intrude tube durability.
