The effect of blood and mucus on the catheter on pregnancy outcomes in frozen-embryo transfer (FET) cycles remains relatively under-investigated. To evaluate the influence of the presence of blood and mucus on the transfer catheter, along with the characteristics of vaginal microbiota on pregnancy o...
