A CAG repeats length of AR gene in controls and polycystic ovary syndrome (PCOS). B CAG allele distribution. Frequency distribution of CAG allele in exon one of AR gene in PCOS cases and controls for short allele, long allele and biallelic average. The blue band represented controls and the red band represented PCOS cases. C CAG repeats length of AR gene in controls, L-AFC and H-AFC PCOS cases. P represented p value given by the least significance difference. L-AFC, low AFC (AFC < 20); H-AFC, high AFC (AFC ≥ 20). D CAG repeats length in AR gene in control, NHA and HA PCOS cases. NHA, non-hyperandrogenism; HA, hyperandrogenism
