mately 500,000 procedures performed annually.1,2 Of these men, 2% to 6% will desire reversal of their vasectomy at a later time.3 Reasons include re-marriage, desire for further fertility, loss of a child, and chronic testicular pain. Vasectomy reversal can be performed in a variety of ways. Both macroand microsurgical techniques have been described and are currently being used by practicing ur...

PURPOSE We report on the early results of fibrin glue assisted, 3-suture microsurgical vasovasostomy (FGV) technique in humans. MATERIALS AND METHODS After Institutional Review Board approval, 42 patients were enrolled prospectively from October 2002 to March 2004. Patients underwent microsurgical 3-suture vasovasostomy with completion of the anastomosis with fibrin sealant. Patient and partn...

We read with great interest the paper by Wilson F. Busato Junior and colleagues (1). In this elegant study two techniques of vasovasostomy have been tested in a laboratory setting. One group of rats underwent “conventional” one-layer anastomosis on the left vas deferent, after transection on the right side; another group was evaluated for a simplified anastomosis performed with one anchor point...

Iatrogenic obstruction of the vas deferens within the inguinal canal can be managed by direct on-site vasovasostomy. However, in cases with large defect of the vas, the anastomosis may be under tension. Dissecting through the site of a previous hernia repair is tedious, and may lead to recurrence of the hernia. The present work reports an, first of a kind, alternative technique that avoids the ...

Male reproduction and male contraception form an important spectrum within men’s health. In this issue’s Views Reviews, four author groups detail new developments in vasectomy clinical practice guidelines, emerging investigational techniques the fields of hormonal nonhormonal contraception, useful paradigms for patient care when deciding between sperm extraction with vitro fertilization reversa...

objective: seeking for fertility after previous vasectomy is increasing. vasectomy may break the blood testis barrier and in this way the level of antisperm antibody increases. it is suggested that increase in antisperm antibody decreases spontaneous pregnancy even after successful vasovasostomy. in this study we evaluated antisperm antibody formation 3 months after vasectomy. method: this stud...

The technique and the results of microsurgical vasectomy reversal in a single-centre study over 18 years are presented. Both vasovasostomy (VV) and epididymovasostomy (EV) were carried out in a three-layer technique. With strict adherence to the strategy, end-to-end VV was only performed if spermatozoa had been demonstrated at the epididymal stump of the vas. In all other cases, EV was carried ...

The pancake problem, which has attracted considerable attention, concerns the number of prefix reversals needed to sort the elements of an arbitrary permutation. The number of prefix reversals to sort permutations is also the diameter of the often studied n-dimensional Pancake network. We consider restricted pancake problem, when only k of the possible n− 1 prefix reversals are allowed.
