PubMed indexes 8 records that name Maca Root and Testosterone together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Maca Root and Testosterone. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Reanalysis of the original serum sample using Elecsys Testosterone II assay, a higher affinity assay, revealed a total testosterone level of 2.9 nmol/l. It is important to exclude assay interference when testosterone level is greater than 5 nmol/l without supportive clinical signs.”
Names both Maca Root and Testosterone in its title.
“Logistic regression analysis showed that Maca has an independent effect on sexual desire at 8 and 12 weeks of treatment, and this effect is not because of changes in either Hamilton scores for depression or anxiety or serum testosterone and oestradiol levels. In conclusion, treatment with Maca improved sexual desire.”
Names both Maca Root and Testosterone in its title.
“Unexpectedly, malondialdehyde (MDA) increased starting from week 8 (W8) in the M60-treated group. In conclusion, Maca nano-emulsion can be recommended at a dose of 60 mg /buck / twice weekly for ten weeks to improve body weight, testosterone levels, and testicular blood supply as well as to enhance antioxidant capacity in New Zealand white bucks.”
Names both Maca Root and Testosterone in its title.
“The oral supplementation of 75 mg/kg of Maca extract in dogs can improve sperm parameters and increase serum testosterone concentrations, leading to improved reproductive capacity. The semen of subjects treated with oral Maca supplementation maintained its parameters stable for a longer period when stored compared to the semen of control subjects, demonstrating the beneficial effect of the use of this extract on male fertility.”
Names both Maca Root and Testosterone in its title.
“The results indicated that combination of maca and lycopene synergistically inhibits BPH in mice. Copyright © 2017 John Wiley & Sons, Ltd.”
Names both Maca Root and Testosterone in its title.
“The testosterone production by Leydig cells significantly increased when cultured with 22R-hydroxycholesterol or pregnenolone and tended to increase when cultured with hCG by feeding the extract powder. The results show that feeding the hydroalcoholic extract powder of maca for 6 weeks increases serum testosterone concentration associated with seminal vesicle stimulation in male rats, and this increase in testosterone level may be related to the enhanced ability of…”
Names both Maca Root and Testosterone in its title.
“In conclusion, RM administered from day 1 to day 14 reduced prostate size and zinc levels in rats where prostatic hyperplasia was induced with TE. Also, this experimental model could be used as accurately assay to determine the effect of maca obtained under different conditions and/or the effect of different products based on maca.”
Names both Maca Root and Testosterone in its title.
“Moreover, serum testosterone levels were not related to prostate or seminal vesicles weight in rats treated with vehicle and Red Maca. In conclusion, Red Maca administered orally in rats seems to exert an inhibitory effect at a level post DHT conversion, on the BPH-induced experimentally, although a direct measure of reductase action would still be required.”
Names both Maca Root and Testosterone in its title.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Maca Root, Testosterone, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
NutriStack is an informational and organizational tool, not a medical service, and not a substitute for professional advice. Always consult a qualified healthcare professional before starting, stopping, or changing any supplement or medication.
