PRP for Recurrent Implantation Failure: New Live Birth Data
A study of 230 women with recurrent implantation failure and endometrial thickness above 7 mm found live birth rates of 45.5% with PRP and 30.0% without it. Patient-selected treatment limits causal conclusions.

Salpingectomy Before IVF: Ovarian Response and Cycle Cancellation
After removal of one fallopian tube, a French study found less favorable follicle recruitment and more cancelled IVF cycles. Egg yields among women reaching retrieval were similar, and causation remains uncertain.

Endometrial Polyps Before IVF: When Does Removal Help?
Polyp removal improved pregnancy rates before IUI in one randomized trial, but its live-birth benefit before IVF remains unclear. The 2026 BFS guidance supports individualized decisions.

ERA After Failed IVF: No Clear Live-Birth Benefit in 1,312 Women
An accepted retrospective study found no significant overall benefit from ERA-guided transfer timing, despite identifying a displaced implantation window in nearly half of tested patients.

Sequential Blastocyst Transfer: Live-Birth Benefit Remains Unclear
In matched groups with previous failed transfers, transferring two blastocysts a day apart was associated with higher clinical pregnancy, but the overall live-birth difference was not significant.

Does PPOS Reduce Euploid Embryos? A 400-Woman IVF Trial
In a randomized trial of women undergoing PGT-A, PPOS and GnRH antagonist stimulation produced similar euploid blastocyst rates and first-transfer outcomes.

Freeze-All vs Fresh Embryo Transfer: What 4,064 IVF Patients Show
A meta-analysis of seven randomized trials found similar cumulative live-birth rates with freeze-all and fresh-transfer strategies, alongside lower OHSS risk with freeze-all.

Adenomyosis and IVF: Does Location Near the Endometrium Matter?
Adenomyosis may differ in its association with reproductive outcomes depending on its location and extent. Two conference abstracts examine junctional-zone involvement, implantation failure, pregnancy loss and live birth—but do not prove causation or a treatment benefit.

Endometriosis and IVF Implantation: Similar Outcomes After Embryo Matching
After matching age and the number and quality of frozen blastocysts, women with and without endometriosis had similar cumulative pregnancy and live birth rates. The retrospective study asks a specific question about the uterine lining.

FET Pretreatment for Endometriosis and Adenomyosis: Early Live Birth Evidence
A retrospective study of 51 women and 217 frozen embryo transfers linked two months of hormonal pretreatment with higher live birth odds. The finding is promising but does not establish a benefit for every patient.
