The results of several studies published over recent months have significantly contributed to our knowledge of the safety profile of oral estrogen-progestogen hormone therapies with respect to the venous system.
Combined hormonal contraceptionWith regard to the safety profile of hormonal contraception, the researchers, clinicians, and the non-medical media alike have been focusing primarily on the increased risk of venous thromboembolism (VTE) [1,2,3]. Until the mid-1990s, the increase in the risk of VTE during the use of combined oral hormonal contraception (COHC) was attributed solely to the prothrombotic effect of the synthetic estrogen contained in the
