Girls born small or underweight twice as likely to be infertile in adulthood

Girls born unexpectedly small or underweight seem to be twice as likely to have fertility problems in adulthood as those of normal size at birth, suggests research published in the online only journal BMJ Open.

Medical advances mean that more underweight and very small babies will survive into adulthood, which might therefore increase the prevalence of fertility problems, say the authors.

But as this is the first research of its kind, further studies will be needed before definitive conclusions can be drawn, they caution.

The researchers base their findings on 1206 women who were born in Sweden from 1973 onwards, and part of a straight couple seeking help for fertility problems at one major centre between 2005 and 2010.

The primary cause of infertility — female, combined, male or unexplained — was gleaned from the patients’ medical records, while details of their birth size, age, and weight were gathered from Sweden’s national medical birth register.

Infertility was attributed to female causes in 38.5% of the cases; male causes in just under 27%; combined causes in just under 7%; and unexplained in 28%.

Around two thirds of the women were of a healthy weight, while around one in four was overweight. One in 20 was obese while almost 2.5% were under weight.

Women whose infertility was attributable to a female cause tended to be heavier than average; excess weight is a known risk factor for infertility.

Just under 4% of the women had been born prematurely; a similar proportion were underweight at birth; while just under 6% were unexpectedly small babies.

Analysis of the data showed that women with fertility problems attributable to a female factor, were almost 2.5 times as likely to have been underweight at birth as those in whom the cause of infertility was attributable to a male factor or unexplained.

Similarly, these women were almost three times as likely to have been born unexpectedly small as those whose primary cause of infertility was unexplained.

These findings held true even after influential factors, including previous motherhood and current weight, were taken into account.

By way of possible explanation, the authors suggest that growth restriction in the womb might affect the developing reproductive organs as previous research has linked fetal growth restriction with reduced ovulation.

And other research has pointed to the fetal origins of some adult diseases, they add.

They caution that the sample size was relatively small and carried out in one geographical area in one country so may not be applicable elsewhere. Further research would be needed before definitive conclusions could be drawn, they say.

But they say that if the associations between low birthweight or small birth size and infertility are confirmed, this may have implications for the prevalence of infertility problems.

“As medical research and care advances, more infants will be born [with low birthweight or small

<p>Question by Joshua: Join fitness programs or not?
I’m a 5’5 male weighing 179lbs 19 years old. This is the heaviest I’ve ever been in my life. I’ve researched on some tips on how to lose weight. I’ve already started on a diet last week consisting of 5-6 light meals a day. I count my calories and I do moderate workouts once or twice a day. I cheat during weekends. This is my first time going on a diet and I’m not sure if what I’m doing is right. I would like to ask if I should join fitness programs like Weight Watchers or JennyCraig etc.
I have a large framesize. I have a goal of reaching at least 145-150 lbs by the end of April. I’m not working or going to school so I have all the time I could use.

    Awesome! I love a woman in good shape. If only there were more women in the
    world who actually take pride in their health & physical well-being. And
    you’d be surprised how much a little muscle mass can help burn fat and
    boost your metabolism. Its sad that most women are afraid to go and pick up
    weights because they’re somehow afraid of getting muscular like a guy,
    which will never happen anyway, and this foolish misconception just holds
    them back from their fat burning potential.

    This is also why women tend to age BADLY compared to men. They just don’t
    take care of themselves or take their health seriously. Once they hit
    37-40? Stick a fork in grandma. They’re not good for much else.

    they get a flat sexy upperbody, fantastic boobs and a wonderful ass. Only

    You won’t get motivated by this. You really get motivated by people who
    started from the bottem. These girls already have the body that you want! I
    dare you get more motivated by watching the progess when you see fat people
    transforming weeks after weeks into this! When i see normal people going
    for goal/sick pack etc.. i’m thinking ‘why don’t i begin doing these
    workouts’ but when i see people doing workouts that already got a six
    pack.. naah.. i give up. they already got it. But if i see the fat one
    transforming into the body you want. I think, i can do it too!

    Not necessary
    You’re on the right track, but need to make sure you are doing 5 days of weights and 5 days of cardio (atleast 15 minutes) those programs are still made by a corporation trying to make money. My mother runs marathons and a lady bigger than her told her she really needs to lose weight and she doesn’t.
    Figure out your BMR ( to maintain your current weight) it is really just as easy as that.
