One of maca's most renowned benefits is the enhancement of sexual desire and function for both men and women. Clinical trials confirm these properties, including maca's support for erectile function. Maca does not directly affect the level of sex hormones in the body. Rather, it seems to work on the glands that synchronize all hormones. This support for endocrine glands, including the adrenals and thyroid gland, may also contribute to maca's effects on stress, mood, energy, and endurance. Maca shares similar properties with red Korean ginseng, which also supports the endocrine glands.
