Objective. To determine the relationship between the consumption of maca, ginger, and ginseng and the relief of andropause symptoms in men over 45 years of age at the El Ermitaño market, Lima, 2025. Methodology. A hypothetical-deductive method was used, with a quantitative approach, correlational scope, cross-sectional design, and basic type. The study consisted of 159 men, and data was collected through a structured survey. Hypothesis testing was performed using Spearman's rho coefficient. Results: 42.8% of participants were between 52 and 56 years old, 28.9% had diabetes, and 28.3% were obese. Regarding the consumption of medicinal plants, 39.6% consumed maca regularly, 50.9% consumed ginger frequently, and 55.3% frequently used ginseng. Most participants perceived them as very safe and consumed them primarily in smoothies. Regarding perceived effectiveness, 53.5% considered maca very effective, 40.3% ginger, and 45.9% ginseng. Furthermore, 66.0% presented moderate symptoms of andropause. A significant relationship was found between the consumption of these plants and symptom relief (p = 0.000). Conclusion: A low, significant positive correlation (rho = 0.335) was identified between the consumption of maca, ginger, and ginseng and the improvement of andropause symptoms in the men evaluated.

Determinación cuantitativa de arsénico, cadmio y plomo en maca (Lepidium meyenii) expendida en el mercado 10 de Octubre durante el período de junio–octubre 2016
(Universidad Privada Norbert Wiener, 2016) Espinoza Dominguez, Judith; Quispe Huillca, Yessica; Lizano Gutiérrez, Jesús Víctor
Maca (Lepidium meyenii) is a plant that grows above 4000 meters of altitude in the Central Andes of Peru, presenting different varieties based on the color of its hypocotyl. For this reason, we conducted a study on 28 samples to quantitatively determine the concentration of Arsenic (As), Cadmium (Cd), and Lead (Pb) in maca (Lepidium meyenii) sold in the Mercado 10 de Octubre during the period of June–October 2016. The average concentration of Arsenic was 0.38 mg/kg with minimum figures of 0.17 mg/kg and maximum figures of 0.67 mg/kg. The average concentration of Cadmium was 0.32 mg/kg with minimum figures of 0.06 mg/kg and maximum figures of 0.62 mg/kg. The average concentration of Lead was 0.34 mg/kg with minimum figures of 0.12 mg/kg and maximum figures of 0.67 mg/kg. The values found were: 29% of the analyzed maca (Lepidium meyenii) samples exceeded the limit permitted by MERCOSUR for As (0.50 mg/kg). 14% of the Cd concentrations in maca exceeded the permitted value given by MERCOSUR for Cd (0.50 mg/kg), and 29% of the analyzed samples exceeded the permitted value given by MERCOSUR for Pb.
