Effects of quercetin supplementation in aging mice on oocyte number, in vitro fertilization and embryo development outcomes.
Article in JBRA assisted reproduction, 2026. 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
objectiveTo investigate the effects of quercetin supplementation in aging mice on the oocyte number and in vitro fertilization outcomes.
methodsThirty-two to forty-week-old aging female mice were randomly assigned into two groups, with one receiving 0.2 mL water contains quercetin 30 mg/kg dissolve in DMSO orally via gavage for 21 consecutive days (n=38). The control group was given 0.2 mL of water containing DMSO without quercetin (n=37). In vitro fertilization was performed after exogenous ovarian stimulation. The outcome was oocyte number and quality, as indicated by oocyte fragmentation rate, fertilization rate, blastocyst formation rate, and blastocyst cell number.
resultsThere was no difference in the number of retrieved oocytes per mouse (17.4±2.6 and 16.2±1.7, p=0.694), oocyte fragmentation rate (30.8% and 26.7%, p=0.108), fertilization rate (43.5% and 43.1%, p=0.877) and blastocyst formation rate (32.6% and 33.9%, p=0.635) in the quercetin group compared to the control group. Likewise, the mean numbers of cells in the ICM, TE, and total cell number in blastocysts from both groups were not different.
conclusionsDietary quercetin supplementation did not improve either the quantity or quality of oocytes. Thus, quercetin supplementation did not improve IVF outcomes in aged mice. However, future studies should incorporate oxidative stress biomarkers to improve mechanistic understanding.
