PURPOSE OF REVIEW: To discuss existing literature and current use of intravaginal culture (IVC) as an option for patients seeking fertility therapies.
RECENT FINDINGS: IVC is the combination of oocytes and sperm with culture media in a sealed device that is placed vaginally and left in place while fertilization and early embryo development occurs. Studies show that IVC is safe, well-tolerated, and has similar outcomes in patients as compared to standard in vitro fertilization techniques (conventional insemination and/or intracytoplasmic sperm injection). The new device, INVOcell, while recommended by the FDA for minimal stimulation and up to 72 h of culture and seven oocytes, has been used successfully with more oocytes and for 5 days (until blastocyst stage for transfer) in many centers. Live birth rates and neonatal outcomes are reassuring.
SUMMARY: Infertility is a common disease and the vast majority of patients globally will not seek care. IVC may improve access to care, lower costs, provide an alternative for patients who have ethical or religious concerns, and be an increasingly utilized option for those seeking ART therapies. It may also ease workflow burdens in labs where space, equipment, or highly trained lab staff are scarce. More data is warranted to track cumulative outcomes and optimize the ideal patient candidate, but it is a viable alternative in the armamentarium of fertility therapies.
