Abstract/OtherAbstract:
INTRODUCTION: The utility of an antithrombotic prophylaxis in Assisted Reproductive Technologies (ART) is highly debated. It has been hypothesised that specific effects of heparin on the coagulation system during implantation can improve the number of clinical pregnancies and live births.
MATERIALS AND METHODS: We studied a cohort of 327 women undergone at least 1 ART cycle before thrombophilia testing. Overall, a number of 751cycles was analysed. Low-Molecular-Weight Heparin (LMWH) and/or low-dose aspirin (ASA) were prescribed in 132 (17.6%) cycles. Furthermore, all the women underwent thrombophilia screening.
RESULTS: The univariate analysis showed that LMWH with/without ASA was significantly associated with both the outcomes clinical pregnancy and live birth, while the use of ASA was not associated with live birth. The logistic regression showed that the use of LMWH was significantly associated with both the outcomes, clinical pregnancy (OR: 6.0, 95%CI: 2.8-15.6) and live birth (OR: 10.7, 95%CI: 3.2-36.1). The type of ART procedure significantly influenced the likelihood of achieving clinical pregnancy.
CONCLUSIONS: Present findings suggest that LMWH alone or combined with ASA could have a role in fostering the implantation of embryos and improving the number of live births after ART.
