If you’re considering IVF to get pregnant, you need to know the latest in vitro fertilization success rates. After all, many factors affect your ability to pregnant, whether making a baby naturally or with IVF.
While it’s impossible to “guarantee” a healthy pregnancy, you can get a good idea of your chances of having a baby based on factors that contribute to reported IVF success rates. Learn about how Attain IVF Programs can increase your chance of IVF success.
4 key factors with IVF success rates
Different factors can affect in vitro fertilization success rates, including:
- Age and IVF. The younger the woman, the higher the IVF success rates. In vitro fertilization success rates decline with maternal age (if you use your own eggs). Lower IVF success rates are the result of a reduced chance of getting pregnant as well as a higher risk for miscarriage, especially after age 40.
Different fertility problems can lower in vitro fertilization success rates. For example, recurrent miscarriage, infertility in both the male and female, uterine abnormalities, blocked or absent tubes, ovarian dysfunction, or low sperm quality and mobility can result in lower IVF success rates.
- Lifestyle habits. Non-smokers and women at a normal body weight may have higher in vitro fertilization success rates. Women with a history of sexually transmitted diseases (STDs) and pelvic inflammatory disease (PID) may have lower IVF success rates.
- The fertility center data. Of course, high IVF success rates are what you want to see when you interview fertility centers. Yet it is important to dig deeper for the facts. Ask more questions to understand the way the IVF success rates are compiled and reported.
Fertility centers have different ways of reporting their IVF success rates. There is the success of achieving pregnancy and there is also the success of having a live birth. The delivery rate per embryo transfer is the true IVF success rate of the clinic, which means the take home baby.
When visiting a fertility clinic, ask for a breakdown of the reported IVF success rates by age and diagnosis. A comparison of the in vitro fertilization statistics against your personal fertility situation can give you a better idea of your possible outcome and IVF success rate.
In addition, a fertility clinic’s IVF success rate depends on factors such as the expertise of their staff, physicians, and laboratory. Some clinics specialize in certain fertility practices. Other clinics may take patients with a lower chance of getting pregnant or women over 40 who want to get pregnant. Both of these situations can affect their reported in vitro fertilization success rates.
What are the latest IVF success rates from the CDC?
The latest CDC data from 2007 reports that based on fresh embryos from non-donor eggs, the percentage of transfers resulting in live birth occurred in:
- 46% of women under 35
- 37% of women age 35-37
- 27% of women age 38-40
- 16% of women age 41-42
What about using frozen embryos from nondonor eggs?
The good news is that when using donor eggs, the age of the recipient does not affect IVF success rates.[i] Using frozen embryos from non-donor eggs, the latest IVF success rates that resulted in live births occurred in:
- 33.6% of women under 35
- 30% of women age 35-37
- 25% of women age 38-40
- 21% of women age 41-42
IVF success rate and multiple embryos
You may wonder if implanting more embryos might increase the chance of pregnancy and increase your IVF success rates. If you are under age 35, transferring more than 2 embryos does not appear to increase the chance of pregnancy. More embryos transferred does, however, increase the chance for a having multiple births.
Does the number of cycles affect IVF success rates?
Some recent findings show that couples who have completed 3 or more cycles of IVF without success may have a lower chance of pregnancy. However, several IVF attempts are recommended in order to achieve the maximum potential of this ART treatment.
Studies show that your chances of IVF success double when you commit to three IVF cycles. Attain IVF Programs provide a financial option that make a course-of-treatment plan affordable.
Although the chances of pregnancy stay the same with each IVF cycle, the accumulative chances increase with the more cycles performed. There also seems to be a slightly higher IVF success rate for those couples that have conceived and given birth using IVF in the past.
The bottom line on IVF success rates
The good news is more women are getting pregnant using IVF than ever before. Talk with your Reproductive Endocrinologist about your age, personal lifestyle habits, and other infertility problems. Ask about the in vitro fertilization success rates at the clinic you are considering. Then ask how these IVF success rates would apply to your personal situation.
