title: [Improvement of male fertility through ligation of varicocele? A study of 100 subfertile varicocele patients three months after ligation (author's transl)].
abstract: With 100 subfertile varicocele patients, three months after ligation (high ligation of the left internal spermatic vein in accordance with Bernardi) had control spermiograms made. An improvement of sperm count (upgrade in a higher class according to MacLeod's partition) was found in 28% of the cases, whereas an improvement of progressive motility was found only in 13%. The percentage of patients reaching the normal value in sperm count of over 40 mill./ml increased from 23% to 39%. The increase in these patients came primarily from the class of 20--40 mill./ml. In progressive motility, there was an increase of patients reaching the standard value of over 40%, from 6 to 11. However, if sperm count and progressive motility together were evaluated in the individual patients after ligation, only 6 patients presented a normospermia, i.e. a sperm count of more than 40 mill./ml with normal progressive motility. Thus 94 of the 100 patients must be considered as subfertile three months after ligation. A significant fertility improvement through ligation of varicocele has not yet taken place.
