The Genetics of Infertility: Current Status of the Field.
نویسندگان
چکیده
Infertility is a relatively common health condition, affecting nearly 7% of all couples. Clinically, it is a highly heterogeneous pathology with a complex etiology that includes environmental and genetic factors. It has been estimated that nearly 50% of infertility cases are due to genetic defects. Hundreds of studies with animal knockout models convincingly showed infertility to be caused by gene defects, single or multiple. However, despite enormous efforts, progress in translating basic research findings into clinical studies has been challenging. The genetic causes remain unexplained for the vast majority of male or female infertility patients. A particular difficulty is the huge number of candidate genes to be studied; there are more than 2,300 genes expressed in the testis alone, and hundreds of those genes influence reproductive function in humans and could contribute to male infertility. At present, there are only a handful of genes or genetic defects that have been shown to cause, or to be strongly associated with, primary infertility. Yet, with completion of the human genome and progress in personalized medicine, the situation is rapidly changing. Indeed, there are 10-15 new gene tests, on average, being added to the clinical genetic testing list annually.

Introduction: Estimates show that about 3-7% of all couples or women around the world have an unsolved infertility problem. Interleukin-17 (IL-17) is a pro inflammatory cytokine involved in the expression of many inflammatory mediators. The aim of this study was to investigate the relationship between (rs2275913G/A) IL-17A gene polymorphism with infertility in women. Methods: This case-control...

Asthenozoospermia is one of the major causes of male infertility, the motility of the sperm is decreased or absent in these men. Male infertility occurs in approximately 50% of infertile couples and among the many genetic causes of infertility, we can mention cytogenetic abnormalities, gene defects, and epigenetic factors. The aberrant mRNA expression of some genes can also impair sperm motilit...
