CONCLUSIONS: Our result suggests that blastocyst formation from INVOCELL intravaginal culture performs slightly better than that of in vitro culture although overall number of usable blastocysts, blastocyst development rate per inseminated oocytes, and pregnancy outcomes are not significantly different.

USE OF INVOCELL INTRAVAGINAL EMBRYO CULTURE SYSTEM FOR FIVE DAYS OF INCUBATION: A PROSPECTIVE STUDY OF SAFETY AND TOLERABILITY.

CONCLUSIONS: In conclusion, our study demonstrates that the INVOcell system can be safely used for a 5-day embryo incubation without causing vaginal irritation or mucosal injury. Our results also verify that the system is well tolerated.

COMPARISON OF FROZEN EMBRYO TRANSFERS (FET) FOR INTRAVAGINAL CULTURE (IVC) AND TRADITIONAL IN VITRO FERTILIZATION (IVF).

CONCLUSIONS: For the first time an evaluation of FET’s for IVC as compared to IVF is shown in this study. This study shows that IVC derived embryos are comparable to conventional IVF derived embryos and a viable treatment option. With comparable outcomes and lower cost IVC embryos provide alternate treatment plan while increasing access to care with improved outcomes as compared to the low cost low success IUI and high cost high success IVF.

DUO INTRAVAGINAL CULTURE (IVC) PROVIDES A POTENTIALLY ADVANTAGEOUS SECOND SOURCE OF EMBRYOS FOR SAME-SEX FEMALE COUPLES.

Marin Fertility Center, Greenbrae, CA

CONCLUSIONS: Same-sex female couples utilizing IVC should consider each carrying an INVOcell device. This approach allows more eggs to be cultured per cycle, requires a minimal amount of extra pre- and post-IVC lab work and potentially safeguards against a poor outcome in the event that one culture system fails to yield any usable embryos.
