| Summary: | The current study was undertaken to determine the 17-β Estradiol (E2) and Progesterone (P4) levels in different milk products and some baby follow-on milk samples collected from retail markets in Türkiye. For this purpose, a total of 50 samples from 8 different product groups with different fat levels, production technologies, and production series were analyzed for natural P4 and E2 levels using a commercial ELISA kit. The highest E2 level was determined in UHT whole milk (3%) (39.20 ± 6.73 pmol·L-1) while the lowest level was found in buttermilk (26.50 ± 1.85 pmol·L-1) samples. For P4 levels, the highest concentration were found in baby follow-on milk (<1 year old) (45.83 ± 2.95 nmol·L-1) and the lowest values were found in pasteurized milk samples (23.00 ± 6.66 nmol·L-1). Also, in this study, differences among the product groups for E2 and P4 were not found statistically (P>0.05). In conclusion, the natural P4 and E2 were detected in all milk and baby follow-on milks at various levels and generally their levels associated with the product fat level.
