Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for certified health advice, travels to or treatment by using a genuine physician. We are not physicians. Always consult your dr. on Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele conditions. Clinical Trials Search.org is a site committed to listing clinical research studies in human subjects. Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele Clinical research trials and Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele health trials occur in hundreds of cities throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectivity of new drugs. The propose of the studies / undertakings is to resolve certain human health questions. Clinical trials are a popular means for physicians, government agencies, and private sector companies to locate treatments for all sorts of conditions, including Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele. Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele Clinical Trials and other clinical trials permit volunteers to acquire medical treatment choices before they are available to the masses. Some times the test subjects obtain professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele clinical trial. Participants oftentimes recieve the most expert healthcare available for their Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele condition. Hazards are a reality, however, and can include extra or frequent physician visits, health risks (potentially life-endangering), and/or the treatment being uneffective. Trials are federally governed with rigorous guidelines to protect clinical trials subjects.

Role of the toxic metal cadmium in the mechanism producing infertility with a varicocele
For Condition: Male Infertility,Non-obstructive azoospermia,Varicocele,Hypospermatogenesis
Status: Recruiting
Sponsor(s): National Institute of Environmental Health Sciences (NIEHS) ,
Synopsis: 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).
