Optimizing Cryopreservation: The Effect of MitoTEMPO and Glycerol Ratios on Ram Semen Quality After Freezing and Thawing.

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
backgroundMitoTEMPO is an important mitochondrial targeted and ROS scavenging antioxidant. It is often used as antiviral, anticancer and immunomodulator agents. In addition, there are studies proving its positive effect on sperm after thawing.
objectivesThe aim of our study was to determine the effects of mitoTEMPO addition, which has strong antioxidant and cryoprotective properties in different glycerol ratios, on motility, kinematics, sperm quality and oxidative stress in spermatozoa after freezing and thawing. MATERIALS AND
methodsSemen was collected from seven rams twice a week for 3 weeks. The semen samples were pooled and extended using standard protocol. Experimental groups were formed (1 µM mitoTEMPO with 3% glycerol, 1 µM mitoTEMPO with 5% glycerol, 5 µM mitoTEMPO with 3% glycerol and 5 µM mitoTEMPO with 5% glycerol) and without (control with 3% glycerol and control with 5% glycerol) mitoTEMPO and they were frozen in mini straws. In this study, motility, kinematic parameters, plasma membrane integrity, mitochondrial membrane potential, acrosome integrity, viability, DNA fragmentation and oxidative stress parameters were determined.
resultsThe increases in total motility, increases in plasma membrane integrity ratio, decreases in MDA level and decreases in DNA damage ratio in mitoTEMPO groups were statistically significant (p < 0.05).
conclusionPost-thawed sperm, the addition of 1 µM mitoTEMPO to the 3% glycerol extender preserved the integrity of the spermatozoon membrane, increased total motility, prevented DNA damage and oxidative stress, and increased the rate of sperm with intact acrosome.
