Millions of women struggle to get pregnant every year. Of those that do get pregnant, many will have a miscarriage. Doctors are working tirelessly to uncover new treatments and therapies that can help women become and stay pregnant more easily. Low dose aspirin has recently come into the spotlight as being a simple yet effective treatment.

History of Aspirin

Over the course of the past century, since it was first discovered, aspirin has enjoyed a roller-coaster ride of success. Once believed to be a wonder drug, capable of relieving practically any pain that ailed you, aspirin's popularity took a hit when it was connected to Reye's Syndrome in children. This caused medical professionals to stop prescribing aspirin as often.

Around 1971, use of low dose aspiring as a prophylactic treatment for cardiovascular disease and stroke was first presented. By 1983, low dose aspirin had become a popular therapeutic treatment for people with heart disease and high blood pressure. One low dose aspirin taken each day can help prevent heart attack and stroke. Additionally, an aspirin taken at the onset of a heart attack can help reduce the severity of the attack.

In the early 1990s, it was discovered that aspirin could be effective in helping women who are suffering from infertility to get and remain pregnant.

There are many causes of infertility in women, and nearly as many treatments to go along with them. Aspirin as a fertility aid is a newer development, only truly popular since the early 1990s. Aspirin is a blood thinner, and has shown promise in helping reduce the likelihood of a miscarriage in women suffering from certain clotting disorders. Thickening of the blood leads to clots forming around the placenta, which can render a pregnancy not viable. Taking aspiring prevents the blood from forming clots, increasing the odds of a successful pregnancy.

Aspirin is also being recommended for women who have suffered preeclampsia, a danger form of serious high blood pressure during pregnancy, in previous pregnancies. Taking low dose aspirin helps reduce the risk of preeclampsia developing again.

Other Benefits of Aspirin in Fertility

In 1999, studies conducted by Argentinian doctors and published in Fertility and Sterility--the journal of the American Society for Reproductive Medicine--found that low dose aspirin taken in conjunction with fertility medication appears to increase the odds of pregnancy by nearly half, as compared with taking just fertility medicine alone. Nearly 50 per cent of women taking the combination became pregnant in contrast with the less than 30 per cent that became pregnant taking only the fertility medication. It is believed that this improvement is due to the aspirin stimulating the ovaries to release more eggs.

Risks Of Taking Aspirin

As with any medication, there are some risks associated with taking low dose aspirin during pregnancy. Aspirin has been known to cause stomach upset, and pregnant women are extremely susceptible to this. If low dose aspirin is taken for a long period of time, it may actually inhibit the ability to get pregnant, as long term use appears to interrupt ovulation.

Dosage and Use of Aspirin

In order for low dose aspirin therapy to be effective in helping a woman to get or remain pregnant, she must begin taking it early in the pregnancy or before she becomes pregnant. The standard low dose is 81 mg.
