The term contraception
means 'against conception or fertilization'. Data published in the Journal of
Human Reproduction shows that about 36 percent of pregnancies across the world

A research conducted
by Kelly Cleland and colleagues of the Princeton University, New Jersey stated
that IUDs can be effectively and safely used as routine contraceptive method.

Unwanted pregnancy is
a serious health concern experienced by couples worldwide. Sufficient
protection is offered by emergency contraception methods. The study states,
"Emergency contraception offers women an important strategy to prevent
pregnancy after intercourse in cases of contraceptive accidents or non-use, or
in situations of sexual violence."
Presently, two forms
of emergency contraceptive measures are available-the IUDs and 'the morning
after pill'. Morning after pills contain 1.5 mg levonorgestrel, sold either in
one-pill or two-pill formulations. Mifepristone in small doses is used
extensively as an emergency contraception measure in China, Russia, India and
gathered data from various databases such as Global Health, Clinicaltrials.gov,
Medline, Wanfang Data (Chinese), Popline, and Weipu Data (Chinese). Studies
published in both Chinese and English were taken into consideration.
The study analyzed 42
studies from six nations that involved about 7,034 females who had some or the
other type of IUDs implanted.
The gap between
intercourse and insertion of IUD was up to around ten days. In majority of the
cases, IUDs were implanted within five days of intercourse. The pregnancy rate
with IUDs was 0.09 percent while with morning after pill it was 1 to 3 percent.
After an unprotected
and unsafe sexual act, IUDs are quite effective in preventing pregnancy or
conception. They are safe, highly effective and low in cost. They should be
considered as 'feasible option' for emergency contraception in couples having
The study revealed clear evidences of intrauterine
contraceptive methods being highly effective in preventing conception as 99.86
percent IUD users did not conceive after an unprotected sexual intercourse.
The researchers further said that the results cannot be specific due to lack of
proper information on fertile cycle days and IUD types.
It was concluded that
IUDs, wherever appropriate and feasible, should be routinely employed as an
effective option for emergency contraception.
