A vasectomy is a permanent form of contraception for a man which involves cutting and tying the vas deferens to prevent sperm from exiting the penis during ejaculation. A vasectomy is a simple procedure which can be performed at a medical clinic using either general or local anaesthetic. A vasectomy reversal is, on the other hand, a much more complicated procedure with a 35% success rate. Vasectomy reversals may be requested in men who have previously had a vasectomy but have now decided to have a baby using natural methods. This section, headed by expert Consultant Urologist, Mr Vijay Sangay, outlines what a vasectomy reversal involves and if the procedure carries any side effects.
