The authors of the study, which is published in Human Reproduction, say their findings suggest that reducing the consumption of UPFs, especially around the time of conception and pregnancy, is better for both parents and embryos. https://medicalxpress.com/news/2026-03-ultra-foods-linked-fertility-embryonic.html Mon, 23 Mar 2026 20:00:02 EDT news693488659 Weight loss drugs have been linked to an increased risk of premature births among women who took them inadvertently just before or during early pregnancy to treat pre-existing diabetes. However, a large study of over 750,000 pregnancies found that there was no link to preterm births or other obstetric complications if the medication was being used to lose weight. The authors of the study, published in Human Reproduction Open, say their findings suggest that it is diabetes rather than the drugs that may be contributing to the increased risk of preterm births.
