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...

two hundred and forty patients, who had undergone vasectomy from 1977 to 1985 and subsequent vasovasostomy ,were studied for the presence of sperm-specific antibodies by using the kibrick's gelatin agglutination test. the number of successful pregnancies and the presence of agglutination were also considered in this survey. sixty-nine pregnancies occurred in total and agglutination was present ...

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.

A small personal series of vasovasostomies and a review of the literature on this subject are presented. The importance is stressed of good counselling before vasectomy is undertaken in the first place.

OBJECTIVE To compare the outcomes of macroscopic one-layer vasovasostomy (MOLVV) with those of two-layer microsurgical vasovasostomy (TLMVV). METHODS Standard TLMVV was performed in 112 men (Group 1), while MOLVV was performed in 94 patients. All of the MOLVVs were performed with number 1 nylon suture as a temporary stent. The outcome measures were as follows: patency rate, pregnancy rate, op...

OBJECTIVE To evaluate the application of a microsurgical two-layer anastomosis technique in the treatment of failed vasectomy reversal. METHODS A microsurgical two-layer anastomosis was used in a series of 24 patients with confirmed anastomotic obstruction after previous vasectomy reversal. The patients were followed up for 9 months to 6 years, and the efficacy of the procedure was evaluated ...

OBJECTIVE Microsurgical procedures are currently the gold standard for vasovasostomy with excellent results, but it takes an increased operative time demanding special training and experience in microsurgery. The objective of this study is to reach the same results with reduced operative time. MATERIALS AND METHODS Male adults Wistar rats were divided into 3 groups: I) 20 rats in control grou...
