Aspirin could increase IVF success rate

Women undergoing in vitro fertilisation (IVF) could increase their chances of becoming pregnant if treated with low doses of aspirin, according to a study published in the May issue of Fertility and Sterility. Researchers at the CER Medical Institute in Buenos Aires, Argentina, compared a group of women who took a daily dose of aspirin whilst taking the ovulation-stimulation drugs normal to IVF with a control group who also underwent ovarian stimulation but took placebo pills instead. The researchers found that 45 percent of women in the aspirin group became pregnant compared with 28 percent in the control group. The study also showed that low doses of aspirin improved ovarian response, uterine and ovarian blood flow velocity, as well as the implantation and pregnancy rate.
