In 7 healthy adult males subjected to bilateral vasectomy spontaneous recanalisation of the divided vas deferens occurred. The vasa had been either resected and tied (3 Group I) or cut and tied (4 Group II). The operation was considered a failure if the wife became pregnant (3 men) or if sperm continued to be found in the ejaculate for longer than the 3-5 months usually considered necessary to empty the vesicles (4). In all 7 men reexplorations were performed and vas segments were removed from… Expand
Delayed spontaneous recanalization of the vas deferens
Eight patients were identified who had undergone successful vasectomy a mean of 4.6 years previously and in whom all were microscopically shown to have recurrent motile spermatozoa in their ejaculate, suggesting an aetiological link. Expand
Histology of the Divided Vas
Histologic studies were done after experimental vasectomy in the rat in order to investigate spontaneous reanastomosis of the vas after vasectomy; this condition was reported in a case whereExpand
Frequency and patterns of early recanalization after vasectomy
Presumed early recanalization was characterized by a very low sperm concentration within two weeks after vasectomy followed by return to large numbers of sperm over the next few weeks. Expand
Regeneration of vas deferens after vasectomy.
The conclusion from the analysis of factors responsible for this selectively proximal process is that sperm secretion was probably a major factor but was certainly not the only factor responsible. Expand
A clinical study of vasectomy failure and recanalization.
Although considered of secondary importance, good surgical technique subjectively measured by the minimal amount of accessory tissue attached to the excised vasa was also considered to aid in reducing the number of vasectomy failures. Expand
Spontaneous reanastomosis of the vas deferens after surgery: a case report.
From review of the literature it was concluded that the best preventive measure is light fulguration of the cut ends and then their separation by covering one cut end by its faschial sheath. Expand
On the surgery of the vas deferens
The technique of vasectomy is presented in which the stumps of the severed vas are exteriorised, and the most promising way seems to be the ligature of the vas which is then exteriorised and wrapped with skinflap. Expand
Does the type of suture material used for ligation of the vas deferens affect vasectomy success?
It is demonstrated that the type of suture material used for ligation of the vas deferens does affect the vasectomy success and the vasection failure rates for individual urologists increased significantly following introduction of Vicryl®. Expand
Experiences of vasectomy for voluntary sterilisation of males.
Voluntary sterilisation of men has increased considerably in Finland since June 1st, 1970, because of the new sterilisation law, and it is still more important to verify the sterility with postoperative sperm analyses. Expand
Late failure of vasectomy after two documented analyses showing azoospermic semen.
From April 1970 to December 1980, 14 047 men underwent vasectomy for sterilisation under local anaesthetic at this clinic, and the wives of six of these men subsequently became pregnant between 16 months and three years after vasectomy. Expand


Bilateral spontaneous reanastomosis of the ductus deferens.

It is emphasized that the vasectomist must explain the possibility of spontaneous reanastomosis of the surgically interrupted ductus deferens to the patient to avoid some of the marital discord that might occurr if the couple is unaware of the possibility. Expand

Because of the situation created in Europe by the mass sterilization procedures of bilateral vasoligation, or resection of the vas, this subject has recently been a matter of concern. Expand
Vasovasostomy: improved microsurgical technique.
2 microsurgical tehniques were employed in dog vasovasostomies and anastomoses patency with excellent morphological and functional repair was achieved, and more fibrosis and scar tissue was noted in dogs in which the first method was employed. Expand
Spermatic granulomas of the epididymis.
Spermatic granuloma probably begins as an inflammatory or traumatic epididymitis that permitted sperm to invade the tissues and play a part in the reestablishment of the spermatic duct after a vasectomy. Expand
Vasectomy for voluntary male sterilisation.
It seems that the number of ejaculations rather than the time interval is more important in achieving azoospermia in the ejaculate after vasectomy. Expand
