Nearly half of all infertility cases are implicated by male factors, such as low testosterone levels and altered semen and sperm health. The purpose of this case series is to share the experience of two men taking a concentrated, highly bioavailable gelatinized form of specific phenotypes (sometimes referred to as colors) of Lepidium peruvianum (Maca-OG\u2122) to improve reproductive health. One man experienced an increase in total testosterone levels and fertility parameters, including sperm concentration, sperm motility, and total sperm count. The second experienced an increase in total testosterone levels, energy, mood, and sleep. This case series highlights a natural alternative for male health to support the body\u2019s production of testosterone, especially when hormone therapy is not medically indicated or desired by the patient, or there are concerns about hormone therapy reducing the body\u2019s production of testosterone.<\/jats:p>","DOI":"10.1177\/15579883241304570","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T06:11:27Z","timestamp":1733724687000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Optimizing Testosterone Levels and Fertility Outcomes: A Case Series on the Impact of\n                    <i>Lepidium peruvianum<\/i>\n                    (Maca-OG\n                    <sup>TM<\/sup>\n                    ) in Andropause and Sperm Dysfunction"],"prefix":"10.1177","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8167-0027","authenticated-orcid":false,"given":"Kim","family":"Ross","sequence":"first","affiliation":[{"name":"College of Nutrition, Sonoran University of Health Sciences, Tempe, AZ, USA"},{"name":"Symphony Natural Health, West Lake City, UT, USA"},{"name":"Symphony Natural Health Institute, West Lake City, UT, USA"},{"name":"Kim Ross Consulting LLC, Lakewood Ranch, FL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8898-650X","authenticated-orcid":false,"given":"Corey","family":"Schuler","sequence":"additional","affiliation":[{"name":"College of Nutrition, Sonoran University of Health Sciences, Tempe, AZ, USA"},{"name":"Symphony Natural Health, West Lake City, UT, USA"},{"name":"Synergy Family Physicians, PA, White Bear Lake, MN, USA"},{"name":"Augsburg University, Minneapolis, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Sklar","sequence":"additional","affiliation":[{"name":"Symphony Natural Health, West Lake City, UT, USA"},{"name":"Reproductive Wellness, Acupuncture and Integrative Medicine, Inc., San Diego, CA, USA"},{"name":"Rejoova, Inc., Westport, CT, USA"},{"name":"The Fertility Expert, Inc., San Diego, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,12,9]]},"reference":[{"key":"bibr1-15579883241304570","doi-asserted-by":"publisher","DOI":"10.3233\/HAB-240032"},{"key":"bibr2-15579883241304570","doi-asserted-by":"publisher","DOI":"10.1111\/and.13755"},{"key":"bibr3-15579883241304570","doi-asserted-by":"publisher","DOI":"10.3390\/genes9070335"},{"key":"bibr4-15579883241304570","doi-asserted-by":"publisher","DOI":"10.1002\/hsr2.2118"},{"key":"bibr5-15579883241304570","doi-asserted-by":"publisher","DOI":"10.1055\/a-1161-0372"},{"key":"bibr6-15579883241304570","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/193496"},{"key":"bibr7-15579883241304570","doi-asserted-by":"publisher","DOI":"10.1159\/000264618"},{"key":"bibr8-15579883241304570","doi-asserted-by":"publisher","DOI":"10.1016\/j.explore.2021.02.009"},{"key":"bibr9-15579883241304570","unstructured":"Leslie S., Soon-Sutton T., Khan M.
