Male Infertility: Present and Future.

ABSTRACT

During the last decade, a sudden decline in human male fertility has become a global concern. Genetic, endocrine and life style related problems are generally considered to be the underlie causes. However, several cases have been reported where hormones fail to promote spermatogenesis. The reason of such reproductive malfunctioning leading to male infertility remains idiopathic. Therefore, a sincere attention with a coordinated multidisciplinary effort by the andrologists, urologists and basic scientists is needed to understand the regulation of the sperm production. Powerful tools like high through put gene expression analyses, genetically manipulated mouse models and tissue culture or transplantation based assays are now available, increasing the scope of a establishing a special line of therapy for idiopathic male infertility. In this review, we have briefly summarized various categories of male infertility with emphasis on current research advancement in this field.
