Average estimated puberty age and standard error (SE) in days, for the genotypes of the SNPs LHR-I499L and IGF1-SnaBI, and the haplotypes of GNRHR; and the P-val for the genotype effect in the model are presented for the two criterions for age of puberty are showed: i) estimated at Scrotal Circumference = 28 cm, ii) estimated at Sperm Motility = 10% and Sperm Concentration = 50 million
