Semen Quality, Hormonal Levels, and Androgen Receptor Gene Polymorphisms in a Population of Young Male Volunteers from Two Different Regions of Poland.

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
backgroundThe population of healthy Polish men has not been frequently and systematically investigated for fertility status. The aim of this study was to assess the quality of semen in a randomly recruited population of young males. The most important task was to find a relationship between semen parameters, sex hormones, and AR gene polymorphism. MATERIAL AND
methodsSemen and blood samples from young men from the Poznan (n=113) and Lublin regions (n=89) were collected for semen analysis, assessment of hormonal concentrations, and calculation of the CAG and GGN repeats of the AR gene.
resultsStatistical comparisons of the hormones and circulating proteins and the seminological parameters revealed significant differences between the regional groups of males studied. Among the correlations found, we emphasize the positive relationship between inhibin B levels and both the number of spermatozoa per ml (R=0.37; p=0.0001) and the total sperm concentration (R=0.40; p=0.00003). Positive correlations between IGF1 and sperm morphology was also found (R=0.40; p=0.000004). The mean number of CAG repeats in our tested groups was 21.93±2.79, in a range from 16 to 31. The mean number of GGN repeats was 23.2±1.66 and ranged from 16 to 29. Numerous significant correlations were found between CAG or GGN repeats and blood hormones or circulating proteins and semen parameters; however, Spearman's rank correlations revealed rather weak coefficients.
conclusionsThis report attempted to determine the quality of semen samples and sex hormones in a population of Polish young men. The results were found to be similar to data obtained in Scandinavia. The calculated means and range of CAG or GGN repeats of the AR gene in Polish males were similar to West European epidemiological data.
