PRL and type 1 diabetes mellitus: It should be noted that, although our group of patients was mostly comprised of women when performing the differential analysis of serum PRL concentrations between men and women, we did not find that gender influenced an increase in serum PRL concentration (T1D male 16.08 ± 13.3 ng/mL vs. T1D female 17.75 ± 14.70 ng/mL and healthy male 4.75 ± 2.42 ng/mL vs. healthy female 4.92 ± 3.65 ng/mL).
