What is Vasectomy

Vasectomy is a dependable method of birth control for men who think their family is complete and will not need children again. It is a simple 15 minute procedure. The objective is to prevent sperm from entering the semen. 95% of which is support fluid made by glands called prostate and seminal vesicles located in the pelvis behind and beneath the bladder

How Vasectomy Works

Vasectomy means removal of part of the vas. The vas (vas deferens to be medically correct) is the tube that carries sperm from the testis up into the groin and back towards the base of the penis. There the sperms are mixed with transport fluid from the prostate gland and enter the storage vessels (call seminal vesicles) where more fluid is added. This fluid (semen) is ready for ejaculation. Only 3% of the fluid ejaculated comes up the vas from the testis so after vasectomy there is no difference in the volume, colour or any other feature of the semen.

After vasectomy, sperms continue to be produced as normal in the testis but they remain trapped in the tubes where they are harmlessly absorbed by the body. Many millions of sperm are left in the reservoirs of the seminal vesicles and these are gradually washed away with every ejaculation. We arrange semen tests at the laboratory at 12 and 14 weeks after vasectomy to ensure that the semen contains fluid only and no sperms. It is recommended that couples have intercourse 3 times per week until submitting the first semen sample to ensure complete emptying of the store of sperms.
