| Abstract | This study evaluated the relationship between pregnancy rate and semen cadmium concentration. This prospective and nonrandomized clinical study analyzed 341 male partners of infertile couples undergoing infertility evaluation and management. Semen samples were collected to analyze semen quality and cadmium concentrations. The main outcome was pregnancy during 60-day infertility treatment. Simple linear regression analysis revealed an association between semen cadmium concentration NS sperm count (r=-0.150, P=0.0416) in nonsmoking subjects (n=184). In both smokers and nonsmokers, semen cadmium concentrations were significantly higher in non-pregnant patients than in pregnant patients. In nonsmokers, Cox multi-variable fertility ratio analysis demonstrated an association between semen cadmium concentration and fertility (fertility ratio of log semen cadmium=0.24; 95% confidence intervals (CI)=0.12-0.47, P<0.0001) after adjusting for related variables. Each tenfold increase in semen cadmium concentration was associated with a 4.17-fold increase in infertility ratio in nonsmoking patients. In smokers, Cox multi-variable fertility ratio analysis demonstrated that sperm count and semen cadmium concentration are associated with fertility (fertility ratio of log semen cadmium=0.17; 95% CI=0.04-0.63, P=0.0085) after adjusting for related variables. In smokers, each tenfold increase in semen cadmium concentration was associated with a 5.88-fold increase in infertility ratio. In conclusion, low levels of cadmium accumulation in semen may contribute to male infertility by reducing sperm quality. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
