IVF success rates
If you are thinking about gestational surrogacy, you’re probably wondering how successful the in vitro fertilisation (IVF) procedure is. What are the chances of this procedure working? How long will it take for you to be able to see your new beautiful baby boy or girl? Here are some of the things that you should know about the IVF success rate and timescales.
IVF Success Rates
It is important to note that age is the main factor which determines whether or not your attempt at IVF will actually produce a baby. The younger the age of the woman whose eggs are being used for the procedure, the greater the rate of success. Success can be considered a live birth. According to the UK's Human Fertilisation and Embryology Authority, the following numbers show rates of success among women who tried the IVF procedure in 2006:
- Women who were younger than 35 had a 28.8% success rate
- Women who were between the ages of 35 and 37 had a 25.7% success rate
- Women who were between the ages of 38 and 39 had a 17.2% success rate
- Women who were between the ages of 40 and 42 had a 10.6% success rate
- Women who were between the ages of 43 and 44 had a 4.9% success rate
- Women who were over the age of 44 had a 0.08% success rate
Keep in mind that going through the procedure at the youngest age possible will increase your chances of success. Older woman may want to consider using an egg donor to increase their chances of conception. Otherwise, traditional surrogacy, in which the surrogate will be artificially inseminated, remains another option that may be viable.
Couples who are considering gestational surrogacy, are likely wondering how long the IVF procedure takes. The procedure will take a little longer than a month. Here is a breakdown of what happens during the IVF procedure to help you develop a better understanding of what happens during this time.
For the first two weeks, the woman will need to receive injections to suppress her natural cycle. After that, she will need to receive fertility hormones for about 12 days to increase the number of eggs that she is producing. An injection will be given to help the eggs mature about 38 hours, or two days, before the eggs will be collected. The eggs and sperm will remain in the laboratory for fertilisation for up to 20 hours. The fertilised eggs, which are now called embryos, will remain in an incubator for up to two days. Some clinics will allow the eggs to mature for up to six days before transferring them into the womb.
The fertility clinic will conduct test in the weeks after implanting the embryos in order to monitor their progress and to determine if the surrogate is pregnant. It is not until the stage of 12 to 15 weeks that the pregnancy is 'officially' confirmed, after the most significant risks of miscarriage have passed.
