While getting pregnant is still a problem for many women around the world, in vitro fertilization is one of the most successful ways at the present. But the question every couple raises is when they should stop. A new study shows that in vitro fertilization can be successful even after five attempts.
Until now, the couples who tried for three times the embryo transfers and didn’t succeed to get pregnant, were considered lost causes. The study published in the American Medical Association Journal shows that approximately two thirds of the women trying the vitro fertilization will get pregnant until the sixth attempt. Researchers say that women shouldn’t give up even after many attempts because some women get pregnant only after they have attempted nine times.
The study involved 157,000 women from the U.K., who underwent in vitro fertilization(IVF) from 2003 to 2010. After the first attempt 29,5% of women gave birth, after the fourth attempt 20,5%, 17,4% after the sixth attempt and 15,7% after the nine attempt.
Doctor Evan R. Myers says that this is the first time that results like this are known. Up until now after the third cycle of IVF, doctors recommended other ways like adoption or eggs donor. But now they encourage patients to go ahead and try as many times as possible.
Even though some people would be extremely happy with the results, other couples find the process really hard emotionally and some don’t have the means to repeat IVF over and over again. According to the American Society for Reproductive Medicine, an in vitro fertilization cycle costs 12,400$. The treatment also includes some risks like birth defects, ovarian cancer, ectopic pregnancy, multiple births, miscarriage and ovarian hyperstimulation syndrome.
The study also revealed that the age is an important factor. Among women younger than 40 years, 32,3% gave birth after the first attempt and 17% after the sixth. Women over 40 years didn’t have such good results, only 12,3% giving birth after the first cycle and after the sixth just 6,9%.
If the fertility problem was caused by the male, a treatment that involved injecting a sperm into each egg was done. By the sixth attempt, the chances of giving birth were up with 71%. When the women used a sperm donor, by the sixth attempt their chances grew with 81%.
Doctor Mark V. Sauer said that a study like this was really needed and praised it, saying that this will give accurate and up to date information to the people trying to get pregnant. Keep in mind that in vitro fertilization can be successful even after five attempts, but don’t forget that it can cost you up to 130,000 $.
