To establish the prevalence of vasitis nodosa in patients who had undergone vasectomy segments of vas deferens resected from 40 patients at the time of vasectomy reversal were examined histologically and immunohistochemically. The findings were correlated with clinical history and postoperative outcome. Controls comprised segments of normal vas deferens excised at vasectomy. Twenty of the 40 va...

Earth's history has been witness to recurrently alternating phases of catastrophic evolution and dominant tectonic deformations, contractions and extension of rifting and spreading leading to quasi-cyclic changes in sedimentary environment and various earth processes. Recent studies have shown quasi-periodicities of 32 2 Million years (Myr) in various endogenic (geomagnetic reversals, magmatic ...

OBJECTIVE Vasectomy, though in some cases are being confronted with irreversibility, has been accepted as an effective contraceptive method. It is estimated that near 2-6% of vasectomised men ultimately show a tendency to restore their fertility. In some cases, vasectomy has been considered as an irreversible procedure due to many post-vasectomy complications causing this debate. The aim of pre...

OBJECTIVE To evaluate the magnitude and range of complications encountered during no-scalpel vasectomy (NSV) and to identify any limiting factor or contraindication to NSV. SUBJECTS AND METHODS A total of 4255 men visiting a family welfare clinic of a city hospital in Delhi, India, or outpatients of the surgery department, opted for NSV; 4253 procedures were performed from September 1989 to D...

OBJECTIVES To determine the differences among the creatine kinase (CK) levels in the spermatozoa of subfertile men with mild, moderate, or severe oligospermia and to examine the differences in CK activity between infertile patients with various clinical diagnoses and a group of normal healthy donors (control). CK is a marker of sperm maturity that correlates with the sperm fertilizing capacity....

Variations in vasectomy techniques have failed to define a means of preventing postvasectomy pain syndrome. In addition, studies examining the pathophysiology of this condition have failed to elucidate a reproducible cause. Prevailing assumptions are focused upon epididymal congestion and obstruction.7 Potentially, up-and-coming techniques such as vasal occlusive gels, currently under developme...

Vasectomy is an elective surgical sterilization procedure for men that is intended to obstruct or remove a portion of both vas deferens, thereby preventing sperm from moving from the testes to the ejaculatory ducts. Although intended for permanent sterilization, vasectomy can be reversed in most men seeking to restore their fertility due to a change in marital status or reproductive goals. The ...

UNDERUTILIZATION OF VASECTOMY IN THE US Male sterilization through vasectomy is far less expensive, less invasive and safer than female sterilization through tubal ligation. Despite vasectomy's advantages, tubal ligation is utilized approximately three times as often, contributing to an overall underutilization of vasectomy in the US. The underutilization of vasectomy may be related to patient ...

Purpose To investigate the incidence, etiology, treatment indications, and outcomes regarding infertile male patients in Japan. Methods Between April, 2014 and March, 2015, the authors contacted 47 clinical specialists in male infertility who had been certified by the Japan Society for Reproductive Medicine. The participating clinicians were sent a questionnaire regarding information on their...
