IVF at Sudha Sundar Clinic is a major treatment for infertility when other methods of assisted reproductive technology have failed. The process involves hormonally controlling the ovulatory process, removing ova (eggs) from the woman's ovaries, and letting sperm fertilise them in a fluid medium. The fertilised egg (zygote) is then transferred to the patient's uterus with the intent to establish a successful pregnancy.

IVF may be used to overcome female infertility in the woman due to problems of the fallopian tube, making fertilisation difficult.

IVF also avails for egg donation or surrogacy where the woman providing the egg isn't the same who will carry the pregnancy to term. This means that IVF can be used for females who have already gone through menopause. The donated oocyte can be fertilised in a crucible. If the fertilisation is successful, the zygote will be transferred into the uterus, within which it will develop into an embryo.

There are five basic steps in the IVF and embryo transfer process, which include the following:

Monitor and stimulate the development of healthy egg(s) in the ovaries.
Collect the eggs.
Secure the sperm.
Combine the eggs and sperm together in the laboratory and provide the appropriate environment for fertilization and early embryonic growth.
Transfer embryos into the uterus.
