Unilateral obstruction or injury to the vas deferens can result in significant injury to the contralateral testicle. Although various pathways have been proposed, the mechanism of contralateral testicular deterioration remains controversial. The present animal study was performed to evaluate the effects of unilateral vasectomy on ipsilateral and contralateral testicular histology and fertility ...

OBJECTIVE To compare pain, discomfort, complications and convalescence during and after vasectomy performed conventionally or using the Li 'no-scalpel' method. PATIENTS AND METHODS Between March 1993 and May 1995, 256 men were vasectomized at two city hospitals in Copenhagen; half of the patients underwent the conventional technique at one hospital and the remaining half the Li method at the ...

BACKGROUND We wanted to determine whether a saline flush during vasectomy would reduce the time needed to reach azoospermia. METHODS During vasectomy men were randomly assigned to flush the prostatic end of the vas deferens with 10 mL of normal saline (intervention group, n = 50), while the remaining men (n = 56) served as controls. Sperm counts were performed on the immediate postprocedure u...

Up to 6% of men who have undergone vasectomy will ultimately elect for reversal in the form of vasovasostomy or vasoepididymostomy for various reasons. Vasovasostomy performed to regain fertility is a technique that has undergone numerous advances during the last century, including the use of microsurgical equipment and principles to construct a meticulous anastomosis. It is important during va...

OBJECTIVES A number of researchers have reported that vasectomy is a risk factor for testicular cancer. However, this conclusion is inconsistent with a number of other published articles. Hence, we conducted this meta-analysis to assess whether vasectomy increases the risk of testicular cancer. MATERIALS AND METHODS We identified all related studies by searching the PubMed, Embase, and Cochra...

Vasectomy is a well accepted global contraceptive approach frequently associated with epididymal granuloma and sperm autoantibody formation. To understand the long-term sequelae of vasectomy, we investigated the early immune response in vasectomized mice. Vasectomy leads to rapid epithelial cell apoptosis and necrosis, persistent inflammation, and sperm granuloma formation in the epididymis. Va...

OBJECTIVE To evaluate cost per delivery using two different initial approaches to the treatment of postvasectomy infertility. DESIGN Model of expected costs and results in the United States in 1994. SETTING Men with postvasectomy infertility, evaluated and treated at centers with experience in vasectomy reversal or sperm retrieval and ICSI. PATIENT(S) Men with postvasectomy infertility, w...

Abstract Introduction The human microbiome has been implicated in a variety of clinical conditions. semen harvests compendium microorganisms that potentially originate different anatomic structures, such as the testis, prostate, and seminal vesicles. However, there is paucity data delineating significance male reproductive health, specifically testicular its role over microbiota. Objective To a...

The situation in Mexico followed a similar pattern. From 1980 to 1988, the Mexican Social Security Institute (the Instituto Mexicano de Seguro Social, or IMSS) performed fewer than 5,000 vasectomies per year. In 1989, the IMSS launched a program to open at least one no-scalpel vasectomy training center in each state. By September 1994, 44 centers had been established, 116 physicians had been tr...

Journal of Family Planning and Reproductive Health Care 2003: 29(2) Abstract Objective. To compare the intra-operative experience and postoperative sequelae between the standard Marie Stopes scalpel vasectomy procedure and electrocautery nonscalpel vasectomy (ENSV) techniques. Design. Randomised prospective comparative study. Setting. Marie Stopes vasectomy centres in the UK. Participants. A to...
