Experience with intravaginal culture for in vitro fertilization (IVF).
It has been reported that intravaginal culture (IVC) yields results comparable to those obtained with classic IVF techniques; furthermore, it can simplify and reduce the costs of the procedure. In our experience with IVC however, only 8 of 78 mature oocytes inseminated (10.2%) fertilized. Possible causes of this low fertilization rate were analyzed. In our opinion this new and attractive technique needs further evaluation before being extended to common clinical practice.
