Providing advance emergency contraceptives has not been able to reduce the number of unwanted pregnancies, a new study published in The Cochrane Library said.
Researchers carried out trials among 7,695 women in India, China, Sweden and the US by providing a number of emergency contraceptives including the "morning after" pill that prevents unwanted pregnancies if consumed within three days of unprotected sex.
However the researchers found that women failed to take the pill even if they were readily available. The researchers speculated that women who were at a high risk of becoming pregnant were unlikely to take the pill compared to women who were at a low risk.
"Our review suggests that strategies for advance provision of emergency contraception which have been tested to date do not appear to reduce unintended pregnancy at the population level", lead researcher Chelsea Polis said.
