Melatonin may directly affect the ovaries by regulating LH mRNA expression; melatonin treatment (10 pM-100 nM) increased the LH receptor mRNA expression in granulosa cells (Tamura et al. 2009). This confirms that higher levels of melatonin in the ovaries can be beneficial, but what concentrations are too high?
