Aspirin may boost pregnancy success
A study in the US found women taking 81mg of aspirin and folic acid every day, when trying to conceive, had a higher rate of conception and live births than women who did not take aspirin.
However, contrary to popular belief, researchers say taking the drug does not mean that you can prevent miscarriages.
It’s believed that aspirin may improve fertility and pregnancy success as it may increase blood flow to the womb.
Up to 1,078 women took part in the trial in the US, published in the Lancet, which found 58% of the aspirin-taking women gave birth compared to 53% of the group who didn’t.
The women were observed by doctors for six months as they tried to conceive and then for up to 32 weeks of their pregnancy.
The research found, however, live birth rates were even higher for women who had just one single miscarriage before 20 weeks pregnancy in the year previous to starting the trial.
Among this more narrowly defined group, 78% of those who took aspirin became pregnant, compared with 66% of those who took the placebo.
Also in this group of women, 62% of the aspirin takers and 53% of the placebo group gave birth.
Aspirin taking pre-pregnancy is less beneficial if you have had 1-2 previous miscarriages in the years previous.
Researchers said additional studies are needed to investigate the finding that aspirin taking after a single, recent pregnancy loss increased pregnancy and live birth rates.
The researchers called for additional research to determine if aspirin therapy might be helpful for improving fertility in other subgroups as well, such as women who can’t establish a pregnancy because the embryo fails to implant in the uterus.
Pregnancy loss occurred in 13% of women in the low-dose aspirin group, compared with12% of women in the placebo group, according to the research.
Up to 1,078 women took part in the trial, either taking the drug or else behaving as a control group.
