Association between dopamine transporter gene () variants and infertility in the Turkish females.

Objective: Worldwide, approximately 10-15% of couples is affected by infertility and infertility is associated with disturbances in female and/or male reproductive systems. The aim of the current study is to investigate the relationship between DAT1 (SLC6A3) VNTR polymorphism with female infertility.

Methods: Genomic DNA extractions were performed in 98 fertile and 90 infertile females, 3' untranslated region (3' UTR) variable number tandem repeat (VNTR) polymorphism of DAT1/SLC6A3 was determined by the use of Polymerase Chain Reaction (PCR) method.
