In Vitro Fertilization (IVF) due to medical reasons

A woman has been having recurring miscarriages. She has had 4 miscarriages in 9 years. Between the first 2 miscarriages and the last 2 miscarriages she gave birth to a child who has been diagnosed with a genetic disorder which manifests as global developmental disorder.

After several consultations with gynaecologists, fertility specialists and genetic specialists, it has been determined that there are two highly likely reasons for the recurring miscarriages.
1. The shape of the womb which can be surgically corrected.
2. Genetic disorders which spontaneously occur when the embryo is formed (Both parents are not carrying any defective gene or any translocations).

The fact that she already has a child with a genetic disorder, there is a possibility of future children being born with a genetic disorder and/or miscarriages to recur.

She has been advised to pursue IVF. Whereby her eggs (number varies according to production in the ovary) are extracted and her husband’s sperm is taken and fertilization takes place outside the body (tube). The embryos are then tested for genetic disorders and the defective ones are discarded. The best one or two are implanted in the uterus and the rest of the non defective ones are kept safely for future use. If they are not used within a stipulated period they are discarded.

Due to the above medical reasons, is it permissible for the woman to pursue IVF treatment?
