a “Surgical attempts to reconnect the [vas deferens] have a success rate of at least 40 percent, and there is some evidence that greater success may be achieved with improved microsurgical techniques. Nevertheless, sterilization by means of vasectomy should be considered permanent.” (Encyclopædia Britannica) “Sterilization should be regarded as a permanent procedure. Despite what the patient may have heard about reversal, reanastomosis is expensive, and success cannot be guaranteed. For women who undergo reversal of tubal sterilization, the risk of ectopic pregnancy is high.”​—Contemporary OB/​GYN, June 1998.
