In case the patient has had a special child from the earlier pregnancy, it is highly advisable to get an embryo biopsy done to avoid complications in the future. Hence, the gynaecologists at the Nisha IVF Centre suggest patients with special child undergo this test and ensure they give birth to a healthy and normal child. Embryo Biopsy PGD – PGS refers to tests that determine the embryo’s health condition and is not affected by genetic disorders or a monogenic disease. This screening ensures that the IVF procedure proceeds with a healthy embryo to ensure a successful pregnancy.
