Aim:
The purpose of the study was to present the scientific output of professors and doctors habilitatus and to assess the factors influencing scientific output.

Material and methods:
The data of scientific output (full text papers from the Web of Science and Scopus) of scientists were presented.

Results:
The mean scientist’s age was 55.7 ± 7.2 yrs, the mean age of receiving PhD 32.7 ± 3.2 yrs, the age of obtaining habilitation degree 45.8 ± 5.6 yrs, the age of attaining professorship 51.2 ± 5.9 yrs, the interval from PhD to habilitation 13.1 ± 4.9 yrs, the interval from habilitation to professorship 7.7 ± 2.7 yrs, the total number of publications 144.6 ± 124.2, the number of publications with an Impact Factor 33.8 ± 31.3, the total value of Impact Factor 61.7 ± 73.2, the citation index 387 ± 531 and index h 8.6 ± 5.3 according to the Web of Science, the citation index 513 ± 756 and index h 9.6 ± 6.0, according to Scopus, the citation index 411 ± 601 and index h 8.6 ± 5.2, according to Scopus without citations of all co-authors. In a correlation analysis, a lower age of habilitation (r ranged -0.29 to -0.36, p < 0.01) and of professorship (r ranged -0.31 to -0.42, p < 0.05) improved the scientific output. Shorter intervals from PhD to habilitation and from habilitation to professorship improved the scientific output as well (r ranged -0.25 to -0.34, p < 0.01, r ranged -0.41 to -0.53, p < 0.01, respectively).

Conclusions:
Scientific output increases with a lower age of habilitation and shorter intervals between PhD and habilitation and habilitation and professorship. The current results should help modify scientific politics supporting the total research impact of the whole division.
