Adults conceived via IVF are well-adjusted with a positive perception of their environment
There are incessant attempts by mean-spirited people to find something wrong with IVF so the facts below might help shut their stupid cakeholes for a while
ADULTS who were born through IVF are just as well-adjusted and satisfied with life as those conceived naturally, the first longitudinal study into IVF children's quality of life has found.
The only significant difference discovered was that young IVF-conceived adults had a more positive perception of their environment, including of their safety, finances and learning opportunities.
Melbourne researchers surveyed about 1100 adults aged 18-29, half of whom were IVF-conceived, measuring 26 life quality factors including satisfaction with relationships, medical treatment needed, sleep and moods.
The research also took into account the person's work status, birth weight and their parents' financial situation.
The findings were presented at the Fertility Society of Australia's annual conference in New Zealand yesterday.
IVF experts say the findings are an important validation that the procedure is safe for children's social and psychological health in the long term.
The first generation of IVF babies are now starting to have their own children, including through artificial fertilisation.
"The results aren't surprising, because there's no doubt these kids were wanted," said Melbourne IVF's medical director Dr Lyndon Hale. "Common sense suggests that these kids would have lots of input from their parents."
The study was a collaboration between researchers from Monash and Melbourne IVF, the Murdoch Children's Research Institute, the Jean Hailes Research Unit, the Royal Women's Hospital and the University of Melbourne.
The mother's smile says it all
Bianca and Matt Smith's two children, nine-week-old Mason and 22-month-old Isla, were both long-awaited arrivals with the help of Melbourne IVF. Ms Smith, 35, said that after years of trying to conceive naturally, she was investing her energy in raising happy, well-adjusted children.
"You long for them for so long. You spend a lot of money and time going through a lot physically and emotionally, and it's all worth it," Ms Smith said.
Why you may NEVER shed those extra pounds: Being overweight can flick a switch that keeps you fat forever
One of the most frustrating mysteries of weight loss is why the pounds seem to inevitably pile back on, following a successful diet.
Researchers found that being obese can reset 'normal' body weight to a permanently elevated level.
Tests in mice found that the longer the animals remained overweight, the more likely their condition would become 'irreversible', making it difficult to maintain meaningful weight loss.
Study author Dr Malcolm Low, from the University of Michigan said: 'Our model demonstrates that obesity is in part a self-perpetuating disorder and the results further emphasise the importance of early intervention in childhood to try to prevent the condition whose effects can last a lifetime.
'Our new animal model will be useful in pinpointing the reasons why most adults find it exceedingly difficult to maintain meaningful weight loss from dieting and exercise alone.'
The researchers used a new model of obesity-programmed mice that allowed weight loss success to be tracked at different stages and ages by flipping a genetic switch that controls hunger. Turning on the switch right after weaning prevented the mice from overeating and ever becoming obese.
Similarly, mice that remained at a healthy weight into young adulthood by strict dieting alone were able to maintain normal weight without dieting after turning on the switch.
However, chronically overfed mice with the earliest onset of obesity never completely returned to normal weight after flipping the switch, despite marked reduction in food intake and increased activity.
The new findings may raise questions about the long-term success rate of severe calorie restriction and strenuous exercise used later in life to lose weight, such as the extreme regimens seen in the popular reality television show 'Biggest Loser.'
Dr Low said: 'Somewhere along the way, if obesity is allowed to continue, the body appears to flip a switch that re-programs to a heavier set weight.
'The exact mechanisms that cause this shift are still unknown and require much further study that will help us better understand why the regaining of weight seems almost unavoidable.'
The research was a result of a collaboration between the University of Michigan and the Argentina-based National Council of Science and Technology. It appeared online in the Journal of Clinical Investigation.
