NCT05034406
Aim of this study is to examine the effects of subcutaneously applied local anesthetics at trocar site in combination with intraoperative intraperitoneal analgesia on duration and character of pain in pediatric patients undergoing laparoscopic varicocelectomy.
NCT04397887
The aim of the study is to assess if seminal TEX 101 can predict the restoration of spermatogenesis and appearance of sperms in the ejaculate after micro-surgical varicocelectomy among azoospermic patients.
NCT03079609
This study is to answer the question is there any relationship between viral ( HSV 1 , HSV 2 , HPV 6/11, CMV, HHV 6 , HHV 8, BKV) or bacterial (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum) infection and occurrence of varicocele in men.
NCT02983383
TAP block is the administration of local anesthetic agents into the anatomic neurofascial cavity between the internal oblique and transversus abdominis muscle in the antero-lateral region of the abdomen to block the anterior branches of the thoracic intercostal (T7-T12) and first lumbar (L1) nerves. TAP block may be a good method for postoperative pain control. We aim to show the effect of TAP block administration on analgesic consumption after varicocelectomy operations, side effects linked to analgesic use and analgesic quality.
NCT02033863
To collect confirmatory data in support of the safety and performance of the ArtVentive Medical Group Endoluminal Occlusion System.
NCT01296230
The purpose of this study is to determine if the pre-operative levels of sex-hormones can be used to identify the varicocele patients who can expect improvements in their semen parameters following varicocelectomy.
NCT00961558
A varicocele is the presence of dilated testicular veins in the scrotum. Although it is generally agreed that a varicocele is the most common identifiable pathology in infertile men (detected in up to 40% of men in some series of men with infertility), the influence of a varicocele on male fertility potential and role of varicocelectomy in restoring of fertility remain the subject of ongoing controversy. The present controversy on the effect of varicocelectomy on male fertility potential has led many clinicians to dismiss the diagnosis of a varicocele altogether and instead, offer alternative treatments to the couple. Many of these alternative therapies are expensive and risky for the patients and their children. Several recent reviews have critically examined the results of randomized, controlled trials of varicocelectomy on fertility potential. The effect of varicocelectomy on spontaneous pregnancy rates remains controversial. The investigators hypothesize that a varicocelectomy will result in a significant improvement in fertility and testicular function in infertile men with a clinical varicocele.
NCT00044369
Varicose veins in the scrotum (varicocele) are responsible for \>20% of male infertility in the US. Varicocele are associated with decreased sperm number and markedly reduced sperm fertilizing ability. Surgical repair or removal of varicocele restores fertility in only 1/3 of cases. The goal of this study is to identify markers that predict the outcome of variocele correction. This would offer considerable health cost savings. Based on preliminary findings, we will obtain testis biopsies and semen specimens from infertile men with varicocele and prospectively examining the levels of cadmium, a toxic metal, and expression of genes required for normal sperm function. The semen and biopsies will be obtained during clinically dictated procedures. Cadmium and gene expression will be compared with response to varicocele repair (i.e., increased sperm production; pregnancy).
