Once the eggs are retrieved, and sperm is collected, they are placed into the INVOCell device. The INVOCell device is immediately positioned in the upper vaginal cavity for incubation, where natural fertilization and early development of the embryos take place. While original clinical studies showed the INVOCell procedure resulting in a lower pregnancy rate vs. standard IVF, more US clinics have gained experience are seeing similar success rates.
A traditional cycle with IVF involves stimulating a woman’s ovaries with injectable fertility medication. The ovaries then produce multiple follicles, and after about ten days, a final trigger injection is given to help mature the eggs. Then under sedation, in our surgery center, a needle is inserted through the back of your vagina, and your eggs are vacuumed out, combined with sperm, then placed inside an incubator in the laboratory. Your embryos grow for up to three to five days and are then transferred back into your uterus.
With INVOCell, a woman’s vagina, which is very temperature-controlled, is used as the embryo incubator. The embryos within the INVOCell device are allowed to develop from three to five days inside your vagina. Once removed, your embryos are examined and based on your age and prognosis, one or two embryos are transferred back inside your. The rest of your embryos can be frozen.
