Embryo Implantation, Delayed

Blastocyst Implantation Inhibition; Blastocyst Implantation Suppression; Embryo Implantation Inhibition; Embryo Implantation Suppression; Blastocyst Implantations, Delayed; Delayed Blastocyst Implantation; Delayed Blastocyst Implantations
Delay in the attachment and implantation of BLASTOCYST to the uterine ENDOMETRIUM. The blastocyst remains unattached beyond the normal duration thus delaying embryonic development.
