From: Genetics of the human Y chromosome and its association with male infertility
Association of gr/gr and b2/b3 deletions with male infertility. Data was obtained from previous studies [105, 126, 167, 188]. Data for gr/gr is derived out of 10,978 and 6704 Y chromosomes from infertile and fertile men respectively. For b2/b3 the data is derived out of 9981 and 5990 Y chromosomes from fertile and infertile men respectively. Infertile men could be oligozoospermic or azoospermic men. Fertile men would be normozoospermic/proven fertile men with unknown sperm counts. Data was divided based on continents or by race. * indicates value significantly different form fertile counterpart
