INVO (intravaginal culture of oocytes), also called IVC (Intravaginal culture) is an abetted procedure of reproduction where early embryo development and oocyte fertilization are carried out inside a gas penetrable, air-free plastic tool or device that is placed into the maternal vaginal chamber for incubation. It is a device that helps the future mothers to participate in the evolution and growth of their own embryos present inside their body. The device is composed of an inner cavity with a protective outer rigid shell and a rotating valve.
It can be used for IVF (In Vitro Fertilization) cycles; whether with the mother's own eggs or any donor's eggs. It provides the same successful results as conventional treatments. It works in a very simple way:- when the requisite samples to produce embryos have been acquired or when the eggs have been impregnated in the laboratory, they together with culture medium are placed into the INVOcell device and then the device is inserted into the vagina of the mother and there it is kept for two to three days (for 72 hours culture period). Throughout this time, the mother can lead a practically normal life but she needs to elude taking bath, having intercourse or flying during those days on which she is wearing it.
When fertilisation takes place, it will be the mother's own heat which will supply the best conditions for the proper development of the embryos. Once they are set and ready, the doctor will remove the INVO from the mother's vagina to recover the embryos. The embryos are then evaluated under the microscope to choose the healthiest-looking ones to transfer them into the uterus. Within the uterus they will be embedded in order to begin developing.
Advantages of INVO are:
Disadvantages of INVO are:
The studies suggest that it could be a usable alternative choice for assisted reproduction. If you wish to discuss about any specific problem, you can consult a gynaecologist.
