Macro shot of white asprin on white.If you are the average woman trying to conceive and want to know if taking a low-dose aspirin every day is a reliable fertility booster, then the answer is simple: not really. There is, however, a small group of women who might experience a fertility boost as a result of taking a daily low-dose aspirin. For these women, the answer is not nearly as simple.

It is a common practice for doctors to prescribe a low-dose aspirin to take daily when a woman has had a miscarriage and wants to conceive again. Until now, there hadn’t really been scientific evidence to support that aspirin helps — but the results from a new study might change that.

Researchers based in Bethesda, Maryland, conducted a study in which 1,000 women who had a history of miscarriage or stillbirth were given either a low-dose aspirin or a placebo. While the study found that the aspirin did not help reduce pregnancy loss overall, it was effective for one particular subgroup: women who had experienced a single miscarriage that occurred before 20 weeks of gestation in the past 12 months. The researchers found that 78 percent of the women in this subgroup who took aspirin got pregnant, verses 66 percent of the women who took the placebo. Of that same group, 62 percent went on to have live births, while 53 percent on the placebo did so.

Miscarriage is more common than most people think. Some estimates say 50 percent of pregnancies end in miscarriage, and other estimates are as high as 60 percent. Experts agree that most miscarriages are the result of abnormalities to the developing embryo, usually the result of chromosome irregularities. Many women who have a miscarriage go on to have successful pregnancies later on, however, with no additional problems.

The research is particularly helpful for women with a condition called antiphopholipid antibody syndrome (APS), an autoimmune disorder that can cause recurrent miscarriages (defined as two or more miscarriages in a row), as well as other problems like blood clots or low platelet counts. APS can prevent phospholipids, which hold dividing cells together and help the placenta grow into the wall of the uterus, from doing their job. Low-dose aspirin might be instrumental in preventing APS from impairing the phospholipids.

When you are trying to conceive, it is important to talk to your doctor about anything you think might give your fertility a boost, including taking a low-dose daily aspirin. If you are part of a specific group, this may in fact help you conceive. For most women, however, low-dose aspirin may help prevent a heart attack but will not help you achieve pregnancy.
