Sextuplets: an unusual complication of single embryo transfer.
OBJECTIVE
To describe an unusual case of a sextuplet gestation after IVF and transfer of a single blastocyst.


METHODS
Case report.


METHODS
University-based IVF clinic.


METHODS
A 32-year-old female with secondary infertility undergoing IVF-ET.


METHODS
Transvaginal oocyte retrieval, transfer of a single blastocyst, and multifetal pregnancy reduction.


METHODS
Ultrasound determination of pregnancy viability.


RESULTS
Six intrauterine gestational sacs, each with a fetus having cardiac activity, reduced to a triplet gestation.


CONCLUSIONS
Physicians should consider advising patients undergoing IVF-ET to abstain from unprotected intercourse at least 4 days before the anticipated oocyte retrieval. Incomplete aspiration of ovarian follicles is uncommon but not rare and can lead to a higher order multiple pregnancy if recent unprotected intercourse has occurred in this setting.
