Culturing immature eggs overnight by rescue IVM increases number of euploids in cycle

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.

The impact of the vaginal and endometrial microbiome on reproductive health and IVF outcomes

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.

Study reviews 34 common male fertility sperm supplement brands for safety, efficacy

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.

Meta-analysis combines 74 studies to examine factors linked to euploid transfer success

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.

Immature eggs cultured overnight by rescue IVM show promising IVF outcomes

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.

Survey examines the use and attitude of natural cycle FETs in US clinics

Researchers in a 2023 study share the results of a survey that evaluates the use and attitude of natural cycle FETs in US clinics, which some studies have recently shown can lead to improved pregnancy outcomes compared to medicated FETs.
