Since its development over 25 years ago, the use of assisted reproductive technology (ART) is on the increase. Along with its use, are also reports of thromboembolic complications (TEC); these events could resulted in significant maternal morbidity and even mortality. In this article, we reviewed the general principles of ART. We also performed a search of all published cases of TEC associated with ART, and summarized the results of studies investigating underlying hemostatic changes with ART. The goal of this article is to provide non-fertility specialists an understanding of ART, so as to better manage TEC when they occur in predisposed patients. The most common ART procedure performed today, is in-vitro fertilization-embryo transfer (IVF-ET). The process of IVF involves the use of exogeneous hormones to achieve cycle control, stimulate the ovaries, and support implantation. During this process, supraphysiological estradiol levels can result. One major complication of this intervention, ovarian hyperstimulation syndrome (OHSS), can be associated with both arterial and venous thrombotic complications. These events (especially venous thrombosis) have also been reported to occur weeks after OHSS has resolved; and they can present in unusual sites (upper extremities) resulting in treatment challenges. From current available studies, it is clear that with ovarian stimulation, both the coagulation and fibrinolytic systems are activated. This activation appears to be exaggerated and prolonged with the development of OHSS. Whether these changes are sufficient by themselves to explain the occurrence of TEC is yet unknown. Future studies should be focused on defining the frequency and risk factors of these complications; provide a closer examination of the resultant changes in the coagulation cascade during ART, OHSS and early pregnancy; and investigating the appropriate treatment and thromboprophylaxis for patients undergoing a procedure considered "elective".
