What is the Success Rate of IVF | IUI Success Rates Australia

Are you considering in-vitro fertilisation, commonly known as IVF? The success of this popular fertility treatment depends on a number of factors you need to be aware of, so it’s important to know them before deciding to start.

What is the Success Rate of IVF: The Factors?

Factor 1: Age

One of the most significant factors affecting the success of IVF is your age. Younger women benefit from higher rates of success, whilst older women can have fewer eggs or eggs of lower quality. Women under 35 who begin IVF cycles enjoy a 40% live birth success rate, whereas in women over 42 the figure is just 4%. However, there are other factors that can improve your chances.

Factor 2: Lifestyle habits

What is the success rate of IVF? Well, depending on how you live and the choices you make, it may be very different from person to person. If you want a child, it’s important you cut down on lifestyle factors that can harm your chances to have a baby. Smoking is a big risk to fertility, so stop immediately if you’re serious about conceiving. Most clinics require a woman to cease smoking at least three months before starting IVF treatment. Not convinced? Here are some smoking stats that might influence your decision:

  • Smokers need higher doses of fertility drugs
  • Smokers have lower implantation rates compared to non-smokers
  • Smokers require twice as many IVF attempts
  • Smokers also tend to experience more failed cycles

It’s also important to try and maintain a healthy weight if you’re overweight or underweight, as obesity can significantly harm your chances to conceive. Overweight women have less IVF success than non-overweight women, and underweight women also have problems.

Factor 3: Type of fertility problems

Male infertility problems can affect IVF success, but so can factors such as uterine abnormalities, fibroid tumours or exposure to DES. Ovulation is vital in the IVF process, so ovarian dysfunctions including high FSH levels indicate low ovarian reserves and reduce your overall chance of IVF success. Large amounts of ovarian stimulant drugs will also reduce IVF success.

Length of infertility is also a key IVF success factor – when both partners have been infertile your chances for success are lower depending on how long you’ve been infertile for.

Factor 3: Previous pregnancy

If you’ve been pregnant previously with the same partner currently undergoing IVF treatment, you’ll have a greater chance of success. However, recurrent miscarriages or a different partner to previous successful pregnancies may decrease the chances.

Factor 4: Donor eggs

Donor eggs are an important part of the IVF process and a key success factor. This is even more apparent if you’re aged between 35-40. Egg quality and the age of donors is an important element of success. Donor eggs from younger women can increase the chances of getting pregnant for older women. Some studies have reported 55% live birth rates for transfers that use fresh eggs/embryos.

 Factor 5: Choice of a fertility clinic

The place you actually attend for your IVF will also impact the chances of a successful conception. You need to carefully select the right centre and fertility specialist in order to avoid picking a clinic that has low rates of success. Some things to think about including the background, skills and experience of the staff at the clinic, as well as the live birth rate of the IVF cycles, started there. You should also ask about the rate of patients who have twins, triplets or other multiple births – and about the laboratory the clinic uses.

Some clinics are also specialists in areas you may find useful. For example, a clinic that specialises in IVF for older women may be helpful if you’re over 35.

Knowledge is vital and ensuring you know everything you can about what is the success rate of IVF and the factors that affect it will give you the best possible advantage. By knowing these factors and staying healthy, you’re giving yourself and your potential children the best chances. If you’d like to know more, contact Dr Jeffrey Persson today.
