A vasectomy procedure does not always prove successful, and neither does a vasectomy reversal operation. Indeed, the success rates of vasectomy reversals can be very low.
The overall success rate of a vasectomy reversal is said to be up to 55% but this figure can be deceiving as each case can be very different. One individual may have a 50% chance of reversing the procedure but the next person may have a less than 10% chance of success.
Approximately 80% of vasectomy reversal patients will regain sperm in their semen. However, just over half of patients will make their partner pregnant in the two years following the surgical procedure.
There are many factors that affect your chances of a successful reversal, with the most significant being as follows:
The time since your vasectomy - the more time that has passed, the more scar tissue that will have developed in the tubes, and therefore the less chance of successful reversal.
The type of vasectomy being reversed and the technique used to do the reversal - some procedures are less difficult to reverse than others.
The presence of additional reproductive problems - these will invariably make successful reversal less likely.
And finally, a successful vasectomy reversal is measured in terms of whether the couple are able to become pregnant. Therefore, the chances of success will also depend on the female partner's age and fertility. Remember, the presence of sperm in the man's semen doesn't guarantee that the couple will fall pregnant.
