My wife and I had been trying to conceive for 14 months without success. My semen analysis showed below-average sperm count (28 million/mL, reference >39) and motility (35%, reference >40%). My urologist recommended lifestyle changes and suggested trying maca supplementation based on several clinical trials showing improvements in semen parameters — specifically black maca, which had the strongest evidence for male fertility.
I started taking 2.5g of black maca powder daily, mixed into a protein shake after my morning workout. I also cleaned up my diet, started sleeping 8 hours, and cut alcohol to weekends only. So this was not a controlled experiment — multiple variables changed.
After 12 weeks, my repeat semen analysis showed sperm count of 48 million/mL and motility of 52%. Both parameters had improved significantly and were now within normal reference ranges. My urologist was encouraged but cautioned that the lifestyle changes likely contributed alongside the maca.
Beyond the lab numbers, I noticed increased libido, better energy levels, and what I can only describe as a general feeling of physical vitality. Whether that was the maca, the better sleep, or the reduced alcohol is impossible to say.
As of writing this, my wife is 11 weeks pregnant. I cannot attribute this to maca specifically — the timing coincided with many positive changes — but I am grateful for whatever combination of factors made the difference. I continue to take maca daily.
