What is In vitro maturation (IVM)?
In vitro maturation is a process of removing the eggs from the ovaries at a time when they are still not mature. Next the proper development to a mature state is done in a laboratory before fertilization. The difference between IVM and IVF is that in the first the eggs are immature at the stage of collection. Which means that the treated woman does not need as many medication before the egg collection.
You may be recommended to do IVM if you are susceptible to ovarian hyper-stimulation syndrome and in cases of the infertility being identified as a male factor infertility.
What thas In vitro maturation involve?
The procedure of IVM involves three steps which are:
- Eggs are collected when they are still immature at an earlier stage – this way less medication is needed.
- In the laboratory eggs are put in a dish in an incubator where they stay for 1 to 2 days until they are mature.
- Finally the eggs are fertilized when they are finally matured using the sperm of your partner or the donor. Next the embryos are cultured and transferred into the womb.
Chances of getting pregnant with IVM or similar to those using IVF. There are few additional risks when undergoing IVM like the fact that there are less eggs to be collected than in a IVF treatment and the general risk of using an aesthetic.
