A recent scientific study has raised concerns about the potential impact of pesticide residue on fertility, particularly among women undergoing reproductive treatments.
The research, conducted under the Environment and Reproductive Health (EARTH) program and published in JAMA Internal Medicine, examined the relationship between pesticide exposure from fruits and vegetables and pregnancy outcomes in women receiving assisted reproductive technology treatments such as in vitro fertilization (IVF).
Researchers monitored more than 300 women who completed dietary assessments before beginning fertility treatments. Using data from the U.S. Department of Agriculture’s Pesticide Data Program, scientists estimated participants’ exposure to pesticide residues through commonly consumed produce.
According to the findings, women who frequently consumed fruits and vegetables with higher pesticide residue levels experienced lower pregnancy success rates compared to those who consumed lower-pesticide alternatives. The study reported reduced chances of both clinical pregnancy and live birth among participants with the highest estimated pesticide exposure.
Researchers also observed an increased likelihood of pregnancy loss among women consuming larger amounts of high-residue produce. However, replacing even one serving of high-pesticide fruits or vegetables with lower-residue options was associated with improved fertility outcomes.
Health experts note that pesticide exposure has previously been linked to reproductive and developmental concerns, though more studies are needed to fully understand long-term effects on fertility.
Produce identified in the study as having higher pesticide residue levels included strawberries, spinach, apples, grapes, potatoes, pears, peaches, and peppers. Lower-residue alternatives included avocados, onions, beans, lentils, cabbage, peas, and corn.
Medical professionals emphasize that fruits and vegetables remain essential components of a healthy diet and should not be avoided entirely. Instead, experts recommend thoroughly washing produce, diversifying food choices, and considering organic options for items known to carry higher pesticide residues.
The study has renewed discussions among public health advocates regarding food safety standards and the need for continued evaluation of pesticide exposure, particularly among individuals planning pregnancy or undergoing fertility treatment.
