Skinny women have low fertility

London:
Being too skinny is far worse for women than being too fat when
trying for a baby.
A study found that such women are less likely to become pregnant
than those who are overweight - including those classed as
dangerously obese.
Fertility specialist Richard Sherbahn, of the Advanced Fertility
Centre of Chicago, said the amount of attention paid to being
overweight meant that the perils of being underweight were being
largely ignored.
The problem was being exacerbated by the "size zero" culture in
girls and young women striving to emulate the skeletal look of
models and other celebrities, the Daily Mail reports.
Sherbahn crunched the figures on almost 2,500 sessions of in vitro
fertilisation (IVF) carried out at his clinic over an eight-year
period.
Being thin can lower the sex hormone oestrogen, making it harder
to get pregnant.
Sherbahn said that while some other studies had hinted that being
skinny may be worse for fertility than being fat, he was
"surprised" at the size of the effect.
It is known that being very thin can make it difficult to get
pregnant naturally, due to a drop in the female sex hormone
oestrogen.
Sherbahn said: "It could be in evolutionary terms that if people
were too thin that maybe food wasn't readily available and maybe
it wasn't the best time to reproduce and maybe the uterus wasn't
at its best."
He added that women were likely to be unaware that it can be more
damaging for their fertility to be too thin rather than too fat.
