Active clinical trials for "Varicocele"

The purpose of this study is to determine whether high ligation of spermatic vein by open operation and microsurgery for patients with are effective in the treatment of varicocele and to determine which surgical option is better.

Two common SNPs are located in linkage disequilibrium in exon 10 of FSHR. The 2039 A>G variant is regularly analyzed to characterize the exon 10 haplotype. In the last years, it has been showed an influence of FSHR 2039 A>G on FSH levels, testicular volume, sperm concentration and the total sperm count. A recent Cochrane review showed a beneficial effect on live birth and pregnancy of gonadotrophin treatment for men with idiopathic male factor subfertility. Which FSHR polymorphism can benefit from FSH treatment is clinically very important, in particular for what regards nonidiopathic patients. In many andrological units, patients underwent adiuvant therapy with purified or recombinant FSH after varicocelectomy. FSH treatment in patients after varicocelectomy could improve spermatogenesis, but there aren't multicentric trials that confirm its validity. Usually, in our hospital only patients with a morphologic aspect of hypospermatogenesis underwent therapy with purified or recombinant FSH, because this therapy is not much useful in patient with Partial Sertoli-cell-only syndrome or maturation arrest. The purpose of our study is to correlate "non responder" patients who underwent FSH adiuvant therapy after varicocele surgery with a p.N680S FSHR polymorphism. Moreover the investigators suppose that "non responder" patients can beneficiate from a high-dose therapy with FSH. This is a prospective intervention study in which are recruited males with OligoAstenoTeratozoospermic (OAT) and varicocele. The partecipants will undergo subinguinal microsurgical varicocelectomy (Marmar technique) and needle aspiration testicular cytology (Foresta technique).

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.

This study will include cryopreserved sperm from infertile azoospermic men, with proven diagnosis of varicocele (clinical & sonographic), which will be used for ICSI in an ART program in Sohag. Patients personal and medical history and socio-demographic data will be retrieved from their saved medical files.

This study is to set the place of microsurgery in surgical treatment od varicocele in infertile male. Fourty patients will undergo microsurgical subinguinal varicocelectomy while the control group consisting of 20 patients wil undergo laparoscopic varicocelectomy.

For infertile men undergoing intracytoplasmic sperm injection (ICSI), data from retrospective studies suggested that varicocele repair may be beneficial and associated with improved livebirth and pregnancy rates, however, its role remains uncertain and disputed. To date, the investigators are not aware of published randomized controlled trail (RCT) that have evaluated whether varicocele repair would improve ICSI outcomes on patients with male-factor infertility.

To evaluate the benefits of laparoscopic Doppler ultrasound (LDU) assisted laparoscopic varicocelectomy (LV) and compare the surgical outcomes and complications between LDU assisted LV (LDU-LV) and microscopic subinguinal varicocelectomy for infertile patients with varicoceles.

Varicocele is a major contributor in male infertility. The improvement of sperm parameters after varicocelectomy supports this contribution. The pathophysiological mechanisms of varicocele-induced male infertility are still under investigation. Cystatin C (Cys C) and endoglin are secreted glycoproteins that recently linked to several cellular changes common in varicocele like apoptosis and autophagy.

The purpose of this study is to evaluate whether clinical varicoceles are associated with abnormal semen parameters and whether varicocelectomy could improve the semen parameter in patients unrelated with infertility.

The aim of this observational study was to evaluate, based on the intraoperative anesthetic that is routinely carried out at the Department of Day Surgery, the difference in timing of the patient's discharge from the hospital (ie when the patient has autonomous demabulation and urination spontaneous) in patients undergoing correction of varicocele according Marmar.
