2. Figure 1
Frequency distributions of androgen receptor CAG repeat length polymorphism in patients with endometriosis (n = 110) and without endometriosis (n = 99). The PCR products ranged in length from 168 bp (9 CAG repeats, genotype A) to 234 bp (31 CAG repeats, genotype W). The number demonstrates the percentage of individual genotype in each group (∗difference existed in the genotype M between both groups). All numbers above the bars are percentages.
