SexSex after vasectomy reversal has to wait  until 2 weeks has passed, minimum. No exceptions. This also includes masterbation and ejaculation of any kind


Why no Sex?

To understand why sex is strongly discourage during the first two weeks after have a vasectomy reversal, it is helpful to recap over what happens when ejaculation takes place.

Ejaculation occurs in two phases. The first phase begins with sperm move along the epididymis and newly joined vas deferens towards the seminal vesicles and prostate. The ejaculated sperms combine with the fluid secreted by the seminal vesicles and the prostate gland in the urethra. The movement of the sperm from the epididymis to the seminal tract is facilitated by contraction of the epididymis.

The second phase begins with the ejaculate being expelled through the external urethra. This is achieved through rhythmic and continuous contraction of the seminal vesicles, prostate, urethra and the pelvic floor muscles that push the semen through the urethra and out of the urethral meatus (opening of the penis) with a certain amount of force.

So, as very fine sutures have been used to rejoin the vas deferens then time must be allowed to pass to stop any forces of any kind from breaking these sutures internally. In all  it takes around 2 weeks for the healing process to complete. At this point, if you feel comfortable, then you can resume intercourse.



After two weeks has passed since your vasectomy reversal, Mr Harriss advises that you have lots of sex without protection.


Common Anxieties

1.What about the old sperm?

Previously it has been asked that people are worried about having intercourse straight away because they are worried about the old sperm causing a bad pregnancy. The old sperm are actually dead and cannot fertilize an egg. Only healthy sperm can fertilize your partner’s egg.


2. When will the fertile sperm come through?

They can come through as soon as you begin having intercourse again.
