IVF
Researchers in a 2022 study compared outcomes from mature M2 eggs and M1-M2 eggs that underwent “rescue in vitro maturation” and found that M2 eggs had improved fertilization, blastocyst conversion and euploidy rates, with no difference in pregnancy or live birth rates.
Researchers in a 2022 study found that women with low β-hCG (<149 mUI/ml) are more likely to have a preterm delivery and abnormal placental pathologies compared to women with higher β-hCG.
Researchers in a 2022 study compared timing of euploid transfers and found that 160 h was optimal for modified natural FETs, while they found no optimal time for natural FETs.
Researchers in a 2022 study performed a systematic review and meta-analysis on women with endometriosis undergoing IVF and found no change in live birth rates, but an increased risk of obstetric and perinatal outcomes, however patients were diagnosed without laparoscopy and didn’t account for treated patients.
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.
