- W2022853847 abstract "Caffeine is a widely consumed substance present in several beverages. There is an increasing consumption of energetic drinks, rich in caffeine, among young individuals in reproductive age. Caffeine has been described as a modulator of cellular metabolism. Hence, we hypothesized that it alters human Sertoli cells (hSCs) metabolism and oxidative profile, which are essential for spermatogenesis. For that purpose, hSCs were cultured with increasing doses of caffeine (5, 50, 500 μM). Caffeine at the lowest concentrations (5 and 50 μM) stimulated lactate production, but only hSCs exposed to 50 μM showed increased expression of glucose transporters (GLUTs). At the highest concentration (500 μM), caffeine stimulated LDH activity to sustain lactate production. Notably, the antioxidant capacity of hSCs decreased in a dose-dependent manner and SCs exposed to 500 μM caffeine presented a pro-oxidant potential, with a concurrent increase of protein oxidative damage. Hence, moderate consumption of caffeine appears to be safe to male reproductive health since it stimulates lactate production by SCs, which can promote germ cells survival. Nevertheless, caution should be taken by heavy consumers of energetic beverages and food supplemented with caffeine to avoid deleterious effects in hSCs functioning and thus, abnormal spermatogenesis." @default.
