In 1918 the first vasectomy on humans is performed for rejuvenation. This was done based on experiments of old senile rats that were transformed after obstructing the outflow from the testes. Two notable people, Sigmund Freud and WB Yeats had vasectomy performed for rejuvenation.
Twyman and Nelson reported a successful case of a vasectomy anastomosis known as a reversal in1938. The patient had a reversal 4 years after having an elective vasectomy. The procedure was recommended due to depression caused by the desire to father children. After the procedure the patient’s emotional condition improved and he was able to father children.
By 1948 the list of indications for vasectomy were: prevention of the insane, criminal or perverse producing offspring, the wife having precarious health and is unable or refuses to undergo tubal ligation, an agreement between the husband and wife to prevent pregnancy, to prevent epididymitis following prostrate surgery, male rejuvenation, and mass sterilization for the purpose of racial limitation/extermination.
In the 1950’s a case is reported of a vassoraphy or repair performed 10 years after the original vasectomy with complete function. The patient’s wife was able to become pregnant 6 months after the procedure. Vasectomy is becoming favorable for use for sterilization. By 1953, vasectomy procedures had been watched for a period of 30 years and were found to have no adverse side effects. Any complications were reported were a result of technical surgical errors. In 1955 Jhaver introduces the single incision, single stitch approach. The advantage being that a bilateral vasectomy was possible using one incision with less surgical trauma and post-operative care. He publishes his technique in 1958.
New techniques continue to appear for vasectomies. In 1967 a new technique is introduced in India by Kothari and Pardanani. They demonstrated that it’s possible to produce a sub fertile sperm count by using a synthetic thread to temporarily obstruct the vas deferens. Removing it would restore fertility. Based on two cases the thread was left in for 20 weeks and 6 weeks later fertility had returned to previous levels. No-scalpel vasectomy was developed in China in 1974 by Dr. Li Shungiang of Chongqing Family Planning Research Institute, Sichuan province. Tubal ligation was the most commonly used method of voluntary sterilization. Vasectomy was not popular with Chinese men. The new technique was minimally invasive with a much lower complication than the conventional method.
