[Defective sterility after vasectomy].

A 32 year old man inpregnated 2 women 5-1/2--7-1/2 months after he had undergone a vasectomy. The patient was revasectomized; no sperm granulomata or third ductus deferens was found. 2-3 cm of the ductus deferens was resected instead of 1-1/2 cm as in the earlier operation, and metal clips were used on the bisected ends instead of catgut. The patient did not win a lawsuit he filed against the hospital. It is recommended that all vasectomy patinets be informed that sterility may not be effected until up to 3 months after the operation. Patients should also be encouraged to have regular control check-ups after the operation.
