Fresh transfer of an average quality slow growing day-3 embryo versus frozen transfer in a poor responder: a clinical management dilemma

A common conundrum faced by clinicians is whether to go for fresh transfer or culture the embryos for future frozen transfer in a case of slow-growing embryo. This case report describes a successful pregnancy with the fresh transfer of a single day 3- 6-cell grade B embryo in a patient with poor ovarian reserve. Although more research is needed in this context, the fresh transfer can be considered as a treatment option in patients with optimal endometrium and well-controlled progesterone levels with slow-growing embryos.
