Resistin belongs to adipokines – the group of hormones secreted mainly by the adipose tissue that can regulate not only energy homeostasis but also reproductive functions. We determined the presence of resistin in the uterus and its impact on the uterine steroidogenesis of pigs, an important farm animal. The obtained results suggest that resistin may interconnect metabolism and reproduction, and in the long-term perspective, these results may help improve farm animal breeding efficiency.
