Although no significant difference (P = 0.051) was observed between the LH levels in AA homozygotes (9.74 IU/L) and GG + GA heterozygotes (11.4 IU/L) in the PCOS group, the LH level is closely related to PCOS pathogenesis, as previously mentioned. This evidence concerns the gene PLOD1 and polycystic ovary syndrome.
