We all know that sugar isn’t the best thing in the world for our health. In fact, most people, when asked will admit to a desire to cut back on their sugar, or acknowledge that sugar consumption is an unhealthy factor in their life. And many of us may hold the opinion that a little bit of sugar is okay, and it probably is, however, a recent study has shown that when it comes to fertility, as little as one sugar-sweetened beverage could decrease a couple’s ability to conceive.1 That’s right, men’s fertility seems to take a nosedive with sugary beverages, too.
Sugar-sweetened Beverage Study
The study was conducted at the Boston University School of Public Health (BUSPH) and published in Epidemiology. It found that the intake of one or more sugar-sweetened beverages per day, by either partner, was associated with a diminished chance of becoming pregnant. Sugar-sweetened beverages include sodas, energy drinks, sugar-sweetened sports drinks and sugar sweetened fruit juices.
It’s Important to Identify Controllable Risk Factors to Help Couples Conceive
It is estimated that infertility affects roughly 15 percent of couples in North America, and costs an estimated 5 billion dollars in health care costs annually. It is important to identify controllable risk factors such as diet to help couples conceive thus reducing the psychological and economic hardship on these individuals.
Pregnancy Study Online (PRESTO)
The study looked at information from the Pregnancy Study Online (PRESTO), an ongoing prospective cohort study of North American couples that is web-based. The researchers looked at 3,828 women (21-45 years) and 1,045 male partners (all couples were living in either the United States or Canada). Participants answered extensive surveys including medical history, diet, lifestyle factors including intake of sugar-sweetened beverages. Female individuals were asked to fill out follow-up surveys every 2 months for a year, or until pregnancy occurred.
Males and Females Consuming Sugar-Sweetened Beverages Are at Risk
Both male and female consumption of sugar-sweetened beverages correlated with a 20 percent reduction in fecundability – the average monthly probability of conception. Females who drank at least one soda a day lowered their likelihood of conception by 25 percent, and males by 33 percent. Intake of energy drinks was related to even larger reductions. Fruit juices and diet sodas were not associated with any significant changes.
Cutting Sugar is Low Hanging Fruit for Fertility Treatment
Given the excess sugar intake of many North American individuals, this is low hanging fruit for fertility treatment. Eliminating sugar as a first line aspect of fertility treatment may be beneficial, and certainly won’t harm anyone.

Node Smith, ND, is a naturopathic physician in Portland, OR and associate editor for NDNR. He has been instrumental in maintaining a firm connection to the philosophy and heritage of naturopathic medicine among the next generation of docs. He helped found the first multi-generational experiential retreat, which brings elders, alumni, and students together for a weekend camp-out where naturopathic medicine and medical philosophy are experienced in nature. Four years ago he helped found the non-profit, Association for Naturopathic ReVitalization (ANR), for which he serves as the board chairman. ANR has a mission to inspire health practitioners to embody the naturopathic principles through experiential education. Node also has a firm belief that the next era of naturopathic medicine will see a resurgence of in-patient facilities which use fasting, earthing, hydrotherapy and homeopathy to bring people back from chronic diseases of modern living; he is involved in numerous conversations and projects to bring about this vision.
