Lepidium meyenii (Maca) does not exert direct androgenic activities

Area of Science:

• Phytochemistry
• Endocrinology
• Pharmacology

Background:

• Maca (Lepidium meyenii) is a Peruvian plant root traditionally used for aphrodisiac and fertility benefits.
• Its purported effects suggest potential interactions with the human endocrine system.

Purpose of the Study:

• To investigate if Maca contains compounds that mimic testosterone.
• To test if Maca extracts can bind to the human androgen receptor.
• To determine if Maca influences steroid hormone signaling pathways.

Main Methods:

• Maca root was extracted using methanol, ethanol, hexane, and chloroform.
• The ability of these extracts to activate the glucocorticoid response element (GRE) was assessed in vitro.

Main Results:

• Maca extracts did not demonstrate the ability to regulate GRE activation.
• The study found no evidence of testosterone-like compounds in Maca extracts interacting with the androgen receptor pathway.

Conclusions:

• Maca extracts, under the tested conditions, do not appear to activate androgen receptor-mediated transcription.
• Additional research is required to identify specific Maca compounds responsible for observed in vivo effects.
