Rescue In Vitro Maturation of a Germinal Vesicle Oocyte Leading to Pregnancy in a Case of Unexplained Infertility.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rescue in vitro maturation (rescue-IVM) refers to the post-retrieval culture of immature oocytes - typically at the germinal vesicle (GV) or metaphase I (MI) stage - under laboratory conditions, allowing them to complete maturation to metaphase II (MII) and become suitable for fertilization. This case report presents a successful pregnancy following rescue-IVM and preimplantation genetic testing for aneuploidy (PGT-A) in a 35-year-old woman with unexplained infertility and a history of ectopic pregnancy. Immature GV-stage oocytes retrieved during in vitro fertilization (IVF) were cultured using standard protocols, and several progressed to MII without pharmacologic stimulation. Following delayed intracytoplasmic sperm injection (ICSI), two euploid blastocysts were obtained, one of which led to a viable singleton pregnancy. This case underscores the clinical relevance of rescue-IVM in IVF cycles with high proportions of immature oocytes, particularly in patients with diminished ovarian reserve or tubal factor infertility. It highlights the importance of individualized assisted reproductive technology (ART) strategies, and the potential of advanced embryology techniques - such as time-lapse monitoring and optimized ICSI timing - to improve outcomes in poor-prognosis cases.
