IVM | In Vitro Maturation

In Vitro Maturation (IVM) is a revolutionary IVF treatment, which has been pioneered by our Scientific Director, Professor R C Chian. It involves the collection of immature eggs, which are then matured in the laboratory. By this method, it is possible to collect multiple eggs without giving hormone stimulation. We were the first IVF clinic in Europe to offer Natural Cycle IVF treatment with IVM.

What is IVM?

During each menstrual cycle, usually only a single follicle (egg sac) grows to the ovulation stage to release an egg for potential fertilisation. However, there are several small follicles called antral follicles in the ovary which contain immature eggs. With IVM these can be collected and matured in the laboratory using special and advanced culture conditions to create several embryos.

Natural IVF is less expensive per cycle than Stimulated IVF treatments as it does not require costly medication.

Who is IVM suitable for?

This treatment can be used for anyone who is ovulating and who is recommended to do IVM by one of our doctors. It can be particularly useful for people for whom time is short, or who are unable to take fertility medication (due to an oestrogen dependent tumour for example). 

Natural Cycle IVF with IVM is also a successful alternative for women with Polycystic Ovaries (PCO) or Polycystic Ovarian Syndrome (PCOS).

'A combination of three things attracted me to CREATE.'

The first one was their more natural and less invasive approach to IVF with reduced amount of drugs. Number two was the quality of their internationally renowned consultants, and number three was their treatment cost. Whilst success rates was also a factor of choice, it was not as important a criteria to me as I first anticipated when I found out the reported figures were often reflective of the clinics’ unwillingness to accept patients with very low chance of success and therefore could not be compared on a like-for-like basis.
