Low doses of aspirin could boost a woman's fertility, finds new research.
The reason for this could be that aspirin increases blood flow to the womb, the researchers said.
However, contrary to popular belief, taking the drug does not prevent miscarriage.
Researchers at the National Institutes of Health randomly assigned more than 1,000 women with a history of pregnancy loss either a low dose of aspirin daily or a placebo.
They then followed them for six months while they tried to conceive.
The researchers found there was no difference in the pregnancy loss rates between the two groups.
However, they found that women who had experienced a single, recent pregnancy loss had an increased rate of pregnancy and live birth while taking a daily aspirin tablet.
These women were classed as those who had lost a baby before four and a half months gestation within the past year.
Among these women, 78 percent became pregnant during the study, compared to 66 percent of those who took the placebo, said the study published in the journal The Lancet.
