Can a bisectimy be reversed?

Vasectomy????: Do you mean vasectomy? A vasectomy is the procedure to "tie off" and occlude the vas deferens, the tubes that transport sperm to the outside world via the ejaculate. A vasectomy is reversible through microsurgery, but the success rate is not great. Several factors affect success: length of time since the vasectomy, scar tissue formation, testicular ability to produce sperm again. See your doctor.

Yes, ...: Yes, vasectomy (I assumed) can be reversed under surgical microscope. But, its success heavily relies on surgeon's skill and the duration after vasectomy. For detail? Ask your intended Doc timely.
