Sperm make up only 2 to 5 per cent of the ejaculate so you will not be able to notice any difference in the volume of your ejaculate. The sperm, which are made in the testicles, cannot pass through the vas deferens once they have been cut and tied, so they are reabsorbed by the body.
It usually takes about ejaculations after the operation before you flush out any remaining sperm from each vas deferens. You should use an alternative method of contraception during this time. After months you should give a semen sample which will be tested to see if any sperm are still present in your ejaculate. More than 99 per cent of vasectomies are effective at preventing pregnancy.
Very rarely, the 2 cut ends of the vas deferens can join together and form an open channel for sperm again — usually in the first few months after the operation.
Having a vasectomy should always be viewed as a permanent measure. However, it can be possible to have a vasectomy reversed in an operation called a vasovastostomy. This operation is more complex than the original vasectomy and takes longer. It often needs to be done under general anaesthetic.
The surgeon has to find the 2 ends of the severed vas deferens and cut off the ties and any scar tissue. Then the 2 new ends have to be very carefully sewn together in a skilful operation. Various statistics are given for the proportion of reversals that are successful — success rates are higher the sooner the reversal is done after the original vasectomy.
Following micro-surgery to reverse a vasectomy, there is gradual recovery of sperm count in most men, but the level of recovery is variable. Factors such as time passed since vasectomy and age are 2 factors that may influence the level of recovery.

They will assess whether the wound has recovered and organize a sperm count. It is best to wait until this checkup before having unprotected sex again. Vasectomies are highly effective. After a full recovery from a vasectomy, there should be no impact on sexual functioning.
