Vitrification can modify embryo cleavage stage after warming. Should we change endometrial preparation?
Our findings suggest that a majority of embryos will develop to morula/blastocyst stage after warming. VET results with morula/blastocysts, and after four days of progesterone supplementation, are better than with cleavage stage embryos.
Our acute studies revealed no improvement in eustachian ventilatory tube function with the administration of nasal decongestants.
