Active clinical trials for "Varicocele"

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).

The purpose of this study is to observe the occurrence of adverse events of live attenuated varicella vaccine.

to evalute the effect inguinal and subinguinal approach of varicoceclectomy on semen parameter for patients complaining of varicocele with normal semen parameter (pain is the main complaint)

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.

To collect confirmatory data in support of the safety and performance of the ArtVentive Medical Group Endoluminal Occlusion System.

Testicular Cancer is the most prevalent malignancy among men between 20 and 34 years of age, with incidence rates rising in western countries including Israel. Cure rate of testicular cancer exceeds 90% with modern treatments. Thus issues such as quality of life (QoL), coping, effects on couple relationships, cognitive function, cognitive orientation and hormonal function become increasingly important. This study aims to assess all these issues using validated, reproducible questionnaires and hormonal plasma levels, and compare them between testicular cancer survivors and controls.

Prospective observational study. A varicocele is defined as a dilatation of the veins in the plexus pampiniformis in the testicles. Varicoceles are a diagnostic dilemma and a therapeutic challenge. Most of the boys with a varicocele don't show any symptoms, but approximately 15-20% experience some sort of infertility later during their life. There still isn't any consensus on when treating the patient is the right choice. Reliable scientific research about parameters able to predict the later stages of the boy with a varicocele is therefore needed. The purpose of this study is to how testicular growth could predict the outcome of boys with a varicocele. During this study, testicular growth in boys with and without a left-sided varicocele will be examined in different schools using ultrasound to measure the testicular volumes, the PRF and the TAI to be able to collect sufficient data with the purpose to be able to predict whether testicular growth is a significant predictor on the progression of a varicocele.
