UNLABELLED The incidence of vasal injury during inguinal herniorrhaphy is estimated at 0.5%. We sought to assess the patency rates and long-term fertility outcome after microsurgical repair of vasal obstruction related to prior inguinal herniorrhaphy. METHODS Twenty procedures were performed on 13 men diagnosed with infertility and vasal injury secondary to previous inguinal herniorrhaphy. Ei...

In this series we present the results of a retrospective analysis of 66 vasovasostomy procedures performed between 1983 and 1991. Obstructive intervals and serum antisperm antibodies were correlated with pregnancy and patency rates. With obstructive intervals of less than 5 years a patency rate of 100% (31/31) was obtained. Even more than 10 years after reversal, pregnancy occurred in 25% (2/8)...

vas was too long to anastomose with the proximal end of the vas, or if the distal vas end retreated into the pelvis and was inaccessible at the inguinal area. This procedure is the same as previously reported. 3 If no sperm were found in the fluid from the proximal vas end, a secondary epididymal obstruction was considered, and the modified transverse intussusception vasoepididymostomy (VE), wh...

PURPOSE The purpose of this study is to evaluate the preoperative factors that influenced postoperative sperm concentration after vasovasostomy. MATERIALS AND METHODS We retrospectively reviewed 97 consecutive single-layer vasovasostomy procedures performed by a single surgeon between March 2003 and September 2010. The patients were stratified into three groups based on sperm concentration at...

Paleomagnetic data on geomagnetic reversals are divided into two general categories: times of occurrence, and records of directional and/or intensity changes for transitions at individual locations. Despite considerable efforts expended in acquiring paleomagnetic reversal records, a detailed picture of the reversal process is still lacking, along with any means of clearly identifying when the m...

Vasectomy is a simple and reliable method of male contraception. A growing number of men after vasectomy request vasectomy reversal due to various reasons. The pregnancy rate is lower than the patency rate after vasovasostomy and the pregnancy rate is time dependent. In this study, we evaluated the influence of reproductive tract obstruction on expression of epididymal proteins and their restor...

PURPOSE Microsurgical vasovasostomy is associated with high patency and pregnancy rates, but is difficult and requires significant effort and time to learn. Therefore, we assessed a simplified loupe-assisted vasovasostomy method using a Prolene stent. MATERIALS AND METHODS The medical records of 82 patients who underwent loupe-assisted vasovasostomy with a Prolene stent by a single surgeon be...
