Abstract:
We performed microscopic sperm aspiration and IVF in 2 cases of distal vas obstruction. 4 cases or epididymal obstruction, 3 cases of congenital vas aplasia. The results were as follows ; 1. The fertilization was successful in 2 cases of distal vas obstruction(100%). 1 case of epididymal obstruction(25%). 1 case of congenital vas. aplasia(33.3%). 2. In 4 cases with Sertoli cell failure. the count and quality of aspirated sperm was lower than in 5 cases with normal hormonal study. The fertilization was successful in 1 case with Sertoli cell failure(25%) and 3 cases with normal hormonal study(60%). In conclusion. microscopic sperm aspiration and IVF proved helpful in treatment of patients with distal vas obstructin, congenital vas aplasia. but the vasoepididymostomy proved more helpful in treatment of patients with epididymal obstruction then microscopic sperm aspiration and IVF until now. When microscopic sperm aspiration and IVF is performed, it seems that in Sertoli cell failure group. there will be lesser fertilization success cases than in normal hormonal study group.
