ApoE genotypes are associated with age at natural menopause in Chinese females

“…In the present study, univariate analysis revealed that the number of pregnancies and live births were significantly associated with the timing of natural menopause, which is consistent with previous studies (Harlow and Signorello 2000;Hefler et al 2005).
