Extract

It has been postulated that undernourishment could affect embryo survival through changes in the uterine environment (Abecia et al., 1995). Moreover, we have shown that undernourished ewes had higher plasma progesterone (P4) concentrations and a lower endometrial content of P4 (Lozano et al., 1998), suggesting that this lower endometrial content could be due to a decrease in the content of endometrial progesterone receptors (PR). The aim of this study was to investigate the effect of low and high levels of food intake on PR in different endometrial cell types.
