Live Birth Rates Independent of Sex-Steroid Levels in Dydrogesterone-Based Programmed-Ovulatory FET: A Shift in Luteal Support Monitoring?

Live Birth Rates Independent of Sex-Steroid Levels in Dydrogesterone-Based Programmed-Ovulatory FET: A Shift in Luteal Support Monitoring?

A multicentric study demonstrates that sex-steroid levels on the day of embryo transfer do not predict live birth rates in a novel programmed-ovulatory FET protocol using dydrogesterone, suggesting that routine hormonal monitoring may be unnecessary when corpus luteum function is preserved.
ICSI vs. Conventional IVF: New Evidence Suggests No Kinetic Advantage and Lower High-Quality Blastocyst Yield in Non-Male Factor Infertility

ICSI vs. Conventional IVF: New Evidence Suggests No Kinetic Advantage and Lower High-Quality Blastocyst Yield in Non-Male Factor Infertility

A secondary analysis of the multicentre INVICSI RCT reveals that ICSI results in fewer high-quality Day 5 blastocysts compared to conventional IVF in patients without severe male factor infertility, with no significant differences observed in embryo morphokinetics or cleavage patterns.
