A Mississippi State doctoral student has received national recognition from the Society for the Study of Reproduction.
Megan Patterson, a doctoral candidate and graduate research assistant in the Department of Animal and Dairy Sciences, has been selected as a Trainee Research Finalist for the 2026 SSR Annual Conference and is the recipient of the USDA Merit Award, which comes with a $500 stipend.
Patterson was chosen to present an oral presentation at the 2026 SSR Annual Conference, which will feature her research on how melatonin administration influences bull reproductive microbiota associated with sperm quality.
"The conference is one of the largest international events focused on reproductive biology, bringing together researchers and professionals from around the world," said Patterson. "I feel honored to receive this opportunity as the selection process is highly competitive."
During a 90-day trial, Patterson supplemented yearling bulls with melatonin, evaluating sperm quality, testicular artery blood flow, scrotal temperature and microbiome composition in both semen and the genital tract. The study found a 5% improvement in sperm motility as well as a decrease in pathogenic bacteria.
"These findings are among the first to demonstrate that nutritional supplementation can significantly alter the semen and reproductive tract microbiome in livestock," said Professor Caleb Lemley, a scientist in the university's Mississippi Agricultural and Forestry Experiment and Patterson's advisor. "Megan's recognition highlights the scientific significance and impact of her work within the field of reproductive biology."
Patterson earned her bachelor's and master's degrees in animal sciences from the University of Tennessee. She plans to graduate in August 2026 and pursue a career in research and development within the animal science industry.
