Don't judge a book by its cover; a quintuplet pregnancy following transfer of five poor-quality embryos.
OBJECTIVE
To report a case of a quintuplet pregnancy following transfer of five poor-quality cellular-stage embryos.


METHODS
Case report.


METHODS
University of Toronto-affiliated infertility clinic.


METHODS
A 35-year-old female with a 2-year history of secondary infertility.


METHODS
Intracytoplasmic sperm injection and embryo transfer.


METHODS
Clinical pregnancy.


RESULTS
Quintuplet implantation with five fetal hearts.


CONCLUSIONS
Because the transfer of five poor embryos resulted in a quintuplet implantation, we recommend that embryos with significant morphologic abnormalities, especially in younger patients, be considered as viable embryos with implantation potential.
