Services for Vasectomy

What is a vasectomy?
​Vasectomy is a surgical procedure performed on male patients to cut the sperm tubes (vas deferens), resulting in permanent contraception.  
Before the procedure
​This method of male sterilisation is more than 99% effective and is deemed permanent. It is advisable to undergo a vasectomy if a man is certain he does not wish to have any more children. 

Vasectomy does not affect a man's sex drive or his ability to achieve erections and ejaculation.  
During the procedure
​Vasectomy is performed as a day surgery procedure either under General Anaesthesia or Local Anaesthesia. 

The operation usually takes half an hour. The effects of the local anaesthetic injected may wear off after 6 to 8 hours. The patient will be prescribed with painkillers and topical medication for wound care. The sutures used are dissolvable and do not require removal.  
After the procedure
​After vasectomy, men are required to undergo a semen test at three months post-operatively to ensure no remnant sperm is found in the tubes. Regular ejaculations (at least 20 times) with use of barrier contraception (e.g., condoms) are necessary until the semen test results are discussed with your urologist.
