Researchers in a 2023 study review the use of 27 IVF add-ons and provide recommendations by ESHRE, with only several that are recommended or could be considered for the general infertility population.
Researchers in a 2023 study found that live birth rates depend on a blastocyst’s grade, and not their day 3 grade, while miscarriage rates were affected due to day 3 cell number.
Researchers in a 2023 study found increased miscarriage rates with mosaic embryo transfers compared to euploids, with no differences in neonatal outcomes.
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 found that older women that are triggered earlier produce immature eggs that may be more competent than mature eggs after rescue IVM.
Researchers in a 2023 study used rescue IVM and found that many immature eggs became mature and had comparable fertilization and euploid rates to sibling mature eggs, although there was a decrease in blastocyst formation rates.
Researchers in a 2023 study found that probiotic supplementation had no impact on positive hCG pregnancy rates, but may improve miscarriage rates.
Researchers in a 2023 study found that embryos that take longer to develop had lower quality scores for both the ICM and trophectoderm, and had reduced clinical pregnancy and live birth rates.
This post reviews what research currently shows about the vaginal and endometrial microbiome and how it may relate to fertility and IVF outcomes. While Lactobacillus species are often considered beneficial and are commonly found in the reproductive tract, studies examining whether microbiome differences actually affect IVF success have produced mixed results.
Researchers in a 2023 study evaluated 34 common male fertility sperm supplement brands for safety and efficacy. They found that the majority exceeded the recommended daily allowance, with two that exceeded the tolerable upper intake level. Less than half had supporting studies for their use, with the overall quality of evidence being ranked as poor.
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.
Researchers in a 2023 study used a procedure called “rescue in vitro maturation” to culture immature eggs collected after retrieval overnight, and found that a high proportion became mature and had comparable fertilization to sibling mature eggs, with many going on to form euploids.
