If you are undergoing or planning to undergo an IVF treatment, the most confusing thing in your mind would be the ‘success rate’ of the procedure. Understanding the success rate is critical in selection of the right clinic and doctor. But first, let us understand what is the IVF procedure exactly.
Here are the steps involved in a successful IVF procedure.
- Stimulation of multiple follicles and eggs to develop
- Egg retrieval to source the eggs
- Artificial fertilization of eggs in the laboratory
- Transfer of embryo to the uterus
The first IVF baby, Louise Brown was born in 1978 in England. Since then hundreds and thousands of families have given birth to babies through IVF. Over 5 million kids have taken birth through IVF and the process has gotten more advanced and efficient with the availability of better technology.
IVF Success Rate
With truckloads of information available over the internet about the success rate of IVF, it has become really difficult to assume whether a piece of info is right or wrong.
The success rate of IVF treatment depends from person to person and a lot of factors play a major role in it as different people respond differently to an IVF treatment. Here are the few major factors which can affect the success of an IVF treatment process.
Factors including recurrent miscarriage or different partners may significantly reduce the success rate. Another factor is that if you has a normal pregnancy earlier, and are now undergoing the IVF process, then the chance of success become greater than normal.
Younger women have higher chances of IVF success in comparison to older women. With increasing age, number and quality of eggs deteriorate significantly. Women under 35 years are reported to have a success rate of around 40 percent while success rate in women above the age of 42 is found to be around 4 percent.
Type Of Fertility Problem
Health conditions like uterine abnormalities, low ovarian reserve, fibroid tumors or DES exposure are some of the factors which decrease the success rate of IVF. Apart from that, some infertility problems in males like low-quality of semen can also affect the outcome.
Chances are also low when both the partners are infertile.
Quality Of Donor Eggs
Donor eggs are used to increase the chances of IVF success for people who lie between 35 to 50 years of age bracket. Eggs of the younger donor are more likely to get fertilized.
Women who smoke have lesser chances of conceiving a baby and experience more failed fertilization cycles. Higher dosage of fertility drugs is given to a smoker to stimulate their ovaries. In many cases, they also need more IVF attempts than a non-smoker for successful implantation.
IVF success rate interpretation is tricky. Hence, while looking for an IVF clinic based on its success rate, consider these factors to make a fair choice.
- Compare the clinic’s success rate to national average success rate of all the clinics.
- Compare the total number of IVF cycles carried out against the number of successful IVF cycles.
- Number of women who had a live birth after being treated at the clinic.
