Gut microbiota, metabolome and hormone profiles associate with pregnancy-related biomarkers in sheep with frozen embryo transfer.
Recipients' gut microbiota and serum metabolites are linked to pregnancy outcomes in frozen embryo transfer (FET), but the underlying integrative mechanisms remain unclear. Here we compared the gut microbiome, serum metabolome, and reproductive hormones between pregnant (P group) and non-pregnant (N group) Small-Tailed...
