Researchers in a 2022 study found no benefit in patients who used the ERA after transferring a single euploid, even when accounting for a history of failed transfers.

What’s the ideal follicle size for IVF? Researchers in a 2022 study compared follicle size at the time of trigger and related it to rates for egg maturity, fertilization, good quality embryos and euploidy. They also examined the association between follicle size and age and BMI.
Researchers in a 2022 study examined the influence of paternal factors, such as semen parameters, paternal BMI and age, on aneuploidy.
Researchers in a 2022 study found that the combination of endometriosis and adenomyosis results in lower cumulative live birth rates after IVF, particularly in those with T2 high-signal intensity myometrial spots as evaluated by MRI.
Researchers in a 2022 study showed that extending embryo culture to day 7 increases the number of useable blastocysts, particularly for older women.
Researchers in a 2022 study reported on the outcomes of 144 “abnormal” embryos, consisting of aneuploids and mosaics, finding a single live birth with an aneuploid and more favorable results with mosaics.
Researchers in a 2021 review examined how sperm and eggs can sometimes be genetically incompatible, based on a group of proteins called human leukocyte antigens (HLA), which may lead to implantation failure or embryo arrest when they’re mismatched.
The post discusses various frozen embryo transfer protocols, which includes a medicated FET, natural cycle FET (true natural/modified natural), and mild ovarian stimulated FET, along with their scheduling. In addition, it examines whether one FET protocol is superior to another, the relevance of the corpus luteum in medicated vs natural cycle FETs, and optimal progesterone levels.
Researchers in a 2022 study compared the impact of endometrial thickness on pregnancy outcomes in fresh and frozen embryo transfer cycles.
