A new study performed an “umbrella review” on the use of supplements for improving female infertility, finding that while studies show improvements in pregnancy outcomes, the quality of the data is low and “insufficient to recommend nutrient supplementation.”
Researchers in a 2023 study found that increasing female BMI resulted in decreased pregnancy and live birth rates after a single euploid transfer, while pregnancy loss rates increased. This effect was reduced in cases of male factor infertility only, suggesting that weight itself may not be responsible.
Researchers in a 2023 study combined the results of 74 studies to investigate what factors contribute to euploid live birth and miscarriage rates, identifying embryo quality, maternal age, specific diagnoses, repeat freeze/thaw, and other factors.
