A vasectomy has no direct bearing on sexual function. No better. No worse. The ability to obtain and maintain erections is unchanged. Since sperm comprise only 5% of the semen volume there is no noticeable change in the quantity or quality of the semen ejaculated. You will be like a Sunkist orange, all juice and no seeds. The force and timing of ejaculation are unchanged. No effect on testosterone levels, desire or libido occurs.

Many couples report a more relaxed and enjoyable sex life once the fear of pregnancy is gone, particularly once condoms are no longer required.

Marriage problems however, are rarely cured by vasectomy. A couple’s sexual problems, low desire or sexual avoidance may stem from fear of pregnancy, but stress, children, fatigue or poor communication can be at play as well. It would be wise to discuss these issues with your partner and your doctor and address them before the vasectomy, just to ensure you are not disappointed later because of unrealistic expectations.

Vasectomy does not protect against sexually transmitted diseases or AIDS. Condoms are therefore still required for sexually risky behaviour.

After a vasectomy the testicles continue to produce sperm but the body’s recycling team, in the form of white blood cells, migrate to the region, engulf and destroy the sperm and return the component molecules into general cellular building blocks via the lymphatic channels. This recycling of dead sperm is nothing new to your body. Prior to having a vasectomy, already about 20% of total sperm production is being recycled as they die off early in the scrotum due to being in some way defective. So blocking the vas just leads to more recycling happening as the normal sperm reach the end of their 3-month life expectancy
