In a report of 192 cases of examinations of both husband and wife for cause of sterility, the husband was found at fault in 33 cases. In 31, few spermatozoa were present and in 2, none. The morphology of @entity1 spermatozoa is described in detail and the results of various staining methods compared. Numerous drawings illustrate observed variations in morphology. The common cause of @entity3893 is an obliterating @entity3892 , usually of gonorrheal origin. Permanent obliteration of the tube of the epididymis is exceptional rather than usual. Persistent obstruction is most often only in the tail of the epididymis. Motile spermatozoa may be found above the block. The obstructed area may be bypassed by attaching the vas to any part of the epididymis on the testicular side of the obstruction or to the vasa efferentia. This operation was successfully accomplished first in experiments on @entity235 . A trial operation was done on a @entity1 with a history of @entity3892 of gonorrheal origin followed by @entity47727 . The cut end of the vas deferens was implanted into an incision in the head of the epididymis and secured with @entity575 -wire sutures. Semen showed many spermatozoa 19 days postoperation. Whether the continuity of the duct will be permanently maintained was not determined.
