Acupuncture
can increase the chances of getting pregnant for women
undergoing fertility treatment by 65%, a review of the evidence
concludes today. Acupuncture, which involves inserting fine
needles under the skin at particular points in the body
depending on the condition being treated, has long been used in
China to help with a range of diagnoses, including regulating
female reproduction. To establish how effective the treatment
is, doctors in the US collated evidence from all relevant,
well-conducted studies and published their conclusions in
today's British Medical Journal.
Eric
Manheimer, research associate at the centre for integrative
medicine at the University of Maryland school of medicine and
colleagues looked at seven studies. All had been published in
English since 2002 and conducted in four different western
countries. The trials involved 1,366 women undergoing in vitro
fertility treatment - where eggs and sperm are removed and mixed
in the laboratory and one or more resulting embryos returned to
the womb. In the trials some women were given genuine
acupuncture, others "sham" acupuncture, such as
putting needles in the wrong places, and some no treatment at
all. Overall the genuine acupuncture improved a woman's chances
of pregnancy by 65%.
All
the acupuncture took place within a day or so of embryo
transfer. Not all the pregnancies would have resulted in a live
birth. In trials where the clinic's pregnancy rate was already
high, there was a smaller, non-significant increase. Manheimer
said the results were not necessarily a reason for every
infertile woman to seek out acupuncture. "I think the
findings should be regarded as somewhat preliminary," he
said. "Acupuncture can improve the rates of pregnancy and
live birth. Some couples might want to choose acupuncture but
others might want to wait until further research has been
done." But Edzard Ernst, professor of complementary
medicine at the Peninsula medical school, Exeter, urged caution.
"IVF may not seem to be 'placebo-prone' but it probably is:
if women expect it to be helpful they are more relaxed, which in
turn would affect pregnancy rates." Manheimer argued a
placebo response was unlikely, arguing that acupuncture may
stimulate the body to produce neurotransmitters which influence
the menstrual cycle, ovulation and fertility. Copyright Guardian
