Hi,
If your friend's wife is suffering from bilateral cornual block, the best option to go with will be IVF.
IVF treatment is one of major and effective treatments in infertility when other methods of assisted reproductive technology have failed. The stage of treatment involves hormonally controlling the ovulatory process, removing ova (eggs) from the woman's ovaries and allowing sperm fertilize them in a fluid medium. The fertilized egg (zygote) is then passed to the patient's uterus with the intent to establish a successful and healthy pregnancy.
