Abstract

OBJECTIVE:

To report a case of a successful pregnancy after trophectoderm biopsy and three-probe fluorescent in situ hybridization of a frozen blastocyst.

DESIGN:

Techniques and instrumentation.

SETTING:

A University Medical Center.

PATIENT(S):

Infertility patient desiring trophectoderm biopsy on frozen blastocyst for preimplantation testing, from an IVF cycle at a referring IVF program.

INTERVENTION(S):

Frozen blastocysts were thawed the evening before the planned transfer. Trophectoderm biopsy was performed in the morning. The fluorescent in situ hybridization results were obtained the same day; embryo transfer was performed under ultrasound guidance.

MAIN OUTCOME MEASUREMENT(S):

Serum betahCG and transvaginal ultrasound.

RESULT(S):

Positive betahCG and ongoing pregnancy.

CONCLUSION(S):

Trophectoderm biopsy can be used as a means for testing frozen blastocysts in patients with excess embryos cryopreserved on day 5 or 6 from previously preformed IVF cycles.
