Sorry gentlemen but if you’re trying to conceive you may want to hold off on the bacon.
According to a new study from Harvard University, the intake of processed meat is associated with lower semen quality in men. Researchers from the Harvard School of Public Health presented on the link between bacon and male fertility at the 2013 American Society for Reproductive Medicine conference.
Drawing their male subjects from Massachusetts General Hospital Fertility Center, the team analyzed sperm samples of 156 volunteers and compared them to each participant’s food intake, as reported on a food intake questionnaire. After adjusting their statistical models for other factors, such as age and body mass index, the team found a negative association between processed meat — including hamburgers, hot dogs and bacon — and sperm quality.
“Processed meat was associated with lower sperm concentration and morphology,” lead researcher Dr. Myriam Afeiche, of the university’s Department of Nutrition, wrote in an email to The Huffington Post. (Morphology refers to the structure and appearance of the sperm.)
While the team found that eating more than one serving of bacon, or other processed meats, related to diminished semen quality, the study also noted a positive association between male fertility and fish consumption.
According to the research, white meat fish like cod and halibut were associated with a higher percentage of normal sperm. Salmon, tuna and other dark meat fish, on the other hand, were related to a higher total sperm count.
Though it seems the findings may add to the growing list of factors that can negatively affect the potency of little swimmers — like too much TV — Afeiche is hesitant to make any diet recommendations for men hoping to conceive, since data is limited.
“The existing literature on diet in general and semen quality is scarce,” Afeiche told HuffPost. “We’ll continue looking into this question including the possibility that it is not processed meats that is driving the association but what they are replacing.”
