Many women want to avoid the use of fertility drugs, often due to an existing medical condition, and so undergo a different type of fertility treatment called In Vitro Maturation (IVM), which is also cheaper than IVF.

How does IVM work?

The main difference compared with IVF is that IVM doesn’t involve the use of fertility drugs. Instead, eggs are collected from the ovaries while they are still immature. They are then grown in a laboratory for one to two days before being fertilised and inserted into the womb.

Is IVM for me?

IVM is particularly suitable for people who prefer to avoid taking fertility drugs, or who are at increased risk of complications of the drugs due to an existing medical condition, such as the one in twenty women who have polycystic ovarian syndrome (PCOS). Not stimulating the ovaries means there is no risk of developing ovarian hyperstimulation syndrome (OHSS), which women with PCOS have a much greater chance of experiencing, and which sometimes requires hospital admission.

How do prices and success rates compare?

IVM is cheaper than IVF for the simple reason that no fertility drugs are required. These drugs can cost up to £2,000, which contributes to the higher cost of IVF.

Whilst IVM is safer, simpler and cheaper than IVF, it is around half as successful per cycle. This means that, for women under 35, the chance of having a baby is around 40% with one IVF cycle and 20% with IVM.  However, for many women it may be a more attractive ‘natural’ alternative.

Do you provide IVM treatment?

Yes – Oxford Fertility was the first clinic in the country to be permitted to offer IVM ten years ago and we’ve continued to pioneer the treatment.
