Identification of g.170G>A and g.332G>A mutations in exon 3 of leptin gene (Bcnl and Cail) and their association with semen quality and testicular dimensions in Sanjabi rams.

The purpose of this study was to investigate leptin gene polymorphisms and their relationships with the characteristics of sperm quality and testicular dimensions. Semen samples were collected from 96 Sanjabi rams during autumn and spring seasons over two years. Simultaneously, the dimensions of length, width and scrotal circumference were measured.
