The Influence of High-Normal Fasting Blood Glucose on Semen Quality, Embryonic Development, and Pregnancy Outcomes.

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
purposeTo investigate the correlation between male high-normal fasting blood glucose (FBG) and semen quality, embryonic development, and pregnancy outcomes of MATERIALS AND
methodsThis retrospective cohort study included 921 couples undergoing their first single blastocyst frozen-thawed embryo transfer cycles. Participants were divided into 4 groups depending on quartiles of male FBG (3.90-6.10 mmol/L): from the lowest Quartile 1 (Q1) to the highest Q4. Firstly, semen quality and reproductive outcomes were compared across groups. Next, based on male FBG quartiles, logistic regression models were performed to explore associations between FBG with semen quality and IVF/ICSI outcomes. Finally, with male FBG considered as continuous variables, generalized additive models (GAMs) were conducted to visualize the non-linear relationship of FBG with the outcomes. Primary outcome: live birth rate (LBR). Secondary outcomes: semen quality, embryonic development parameters, biochemical pregnancy rate (BPR), clinical pregnancy rate, miscarriage rate, and other pregnancy outcomes.
resultsHigher FBG quartiles exhibited significantly reduced sperm total motility, progressive motility, and progressive sperm count, alongside increased asthenozoospermia prevalence (p<0.05). BPRs rose from Q1 (4.4%) to Q4 (11.0%) (p=0.033), while LBR showed a declining trend from Q1 (46.7%) to Q4 (36.0%) (p=0.102). Regression analysis indicated that males in Q4 had a higher biochemical pregnancy risk and lower live birth likelihood (p-trend<0.05). GAMs revealed a dose-dependent increase in both asthenozoospermia and biochemical pregnancy risks with rising FBG levels.
conclusionsHigh-normal male FBG is significantly associated with both impaired semen quality (particularly asthenozoospermia) and adverse IVF/ICSI outcomes, including increased biochemical pregnancy risk and reduced LBRs. These findings highlight the significance of assessing paternal metabolic health and suggest that FBG screening may serve as a valuable tool for optimizing IVF/ICSI strategies and improving reproductive success.
