In the non-PCOS patients, there were significant relationships between LH and pain (n=87, rho=0.26, P=0.015),prolactin level and lubrication (n=85, rho=0.22, P=0.048),prolactin level and total FSFI (n=85, rho=0.22, P=0.045),and central obesity and arousal (n=93, rho=-0.26, P=0.013).In the PCOS group, marital duration and arousal (n=103,rho=-0.31, P=0.001), marital duration and total FSFI(n=103, rho=-0.25, P=0.013), and prolactin level and orgasm (n=114, rho=-0.23, P=0.012) were correlated. The gene discussed is PLOD1; the disease is polycystic ovary syndrome.
