As a woman not ready to have children just yet and exploring options for preserving your fertility, one hesitation you may have is the fear that in vitro fertilization (IVF) and the fertility drugs used may have some impact on a child's health or mental health as they grow up.
There is good news on that front — very good news.
The first into IVF children's quality of life has found that adults who were born from IVF are just as well adjusted and satisfied with life as those conceived naturally. In addition, young IVF-conceived adults had more more positive perception of their environment, including of their safety, finances and learning opportunities.
The findings were presented by Melbourne, Australia, researchers at the Fertility Society of Australia's annual conference in New Zealand. They surveyed about 1,100 adults aged 18-29, half of whom were IVF-conceived.
In more good news out of Australia, researchers have debunked the theory that higher levels of hormones given to women for IVF lead to more chromosome abnormalities in the embryos. The research, performed by Genea, a fertility clinic in Sydney, involved 166 women under the age of 38 whose embryos underwent chromosomal analysis.
Aneuploidy (abnormal chromosomes) are the most common cause of miscarriages.
Still, IVF does pose some risks. Recent U.S. research presented at the American Academy of Pediatrics Conference, found that IVF may increase the risk of birth defects in the heart, eyes, reproductive organs and urinary systems.
In their study, researchers at the University of California, Los Angeles, found that 9 percent of infants born after IVF had birth defects compared to 6.6 percent of babies who were conceived naturally. It is possible that whatever was contributing to the parents' infertility migh have contributed to the birth defect risk.
It's important to note tha the overall risk of birth defects is sstill small. .
When the American Society for Reproductive Medicine (ASRM) lifted the "experimental" label for egg freezing, the researchers also reported that they had found no increases in birth defects, chromosomal abnormalities and developmental disorders among babies born using frozen eggs.
Still ASRM says that more long-term research is needed to determine if the rate of developmental anomalies among babies born from frozen eggs is similar to children born from frozen embryos.
