Undergoing assisted reproduction treatment can be exhausting and exhausting for the couple, as well as very expensive. Currently, in vitro fertilization treatments are limited to 3 or 4 attempts, but A new study supports expanding in vitro fertilization cycles beyond that number.
Couples who can persist and have the courage to do so are more likely to have a baby because repeated cycles of IVF continue to increase the probability of a live birth.
Usually, after 3 or 4 unsuccessful embryonic transfers, it is considered that there are "repeated implantation failures", but a new study by scientists from the University of Bristol, United Kingdom and published in the journal 'JAMA' concludes that keep trying it's worth it.
The results are quite encouraging. The study was conducted with 156,947 women who received 257,398 cycles of in vitro fertilization of ovarian stimulation between 2003 and 2010 and were followed until June 2012. The average age at the beginning of treatment was 35 years and the average duration of infertility For all cycles it was 4 years.
In all women, the live birth rate for the first cycle was 29.5 percent, staying above 20 percent in the fourth cycle. The live birth rate adjusted to the cumulative prognosis in all cycles continued to increase until the ninth cycle, with 65 percent of women getting a live child in the sixth cycle.
If we divide the results according to the age of the woman. In children under 40 years with their own oocytes (ovules), the rate of live births for the first cycle was 32 percent and remained above 20 percent until the fourth cycle. Six cycles achieved a cumulative adjusted live birth rate of 68 percent
For women 40 to 42 years of age, the live birth rate for the first cycle was 12 percent, with 6 cycles achieving a live birth rate adjusted to an accumulated prognosis of 31.5 percent.
