Blocked tubes means that your vas deferens or epididymis tubes are blocked or damaged. If you have this kind of condition, then you have a very low probability of having a child because this prevents your sperm from getting to your partner’s egg.
There is no possible symptom if you have blocked tubes. The possible solution is surgery in order to repair an obstruction or obtain a collection of sperm. An in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is recommended to be done after the surgery is successfully performed. Take note that there are about 50 to 80 percent of men have sperm in their semen after surgery, but less than half impregnate their partner within a year. About 25 to 40 percent of couples conceive with IVF or ICSI.
