Gonadotropin values are presented as the mean ± standard deviation. Values in parentheses indicate the proportion (%) in each group. The concentrations of gonadotropin were compared using the Mann-Whitney U test. The proportions reporting menstrual disorders were compared using the chi-square test. A p-value < 0.05 was considered significant.
Abbreviations: LH: Luteinizing Hormone; FSH: Follicle Stimulating Hormone.
