Objective:
To describe an unusual case of a sextuplet gestation after IVF and transfer of a single blastocyst.
Design:
Case report.
Setting:
University-based IVF clinic.
Patient(S):
A 32-year-old female with secondary infertility undergoing IVF-ET.
Intervention(S):
Transvaginal oocyte retrieval, transfer of a single blastocyst, and multifetal pregnancy reduction.
Main Outcome Measure(S):
Ultrasound determination of pregnancy viability.
Result(S):
Six intrauterine gestational sacs, each with a fetus having cardiac activity, reduced to a triplet gestation.
Conclusion(S):
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.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
