A team of researchers has suggested that some progesterone-only hormonal contraceptives may carry similar clot risk to certain combined pills, according to theirstudy.The Danish scientists had examined the risk of developing venous thromboembolisms (VTEs) associated with different types of synthetic progesterone and oestrogen, such as norgestimate, levonorgestrel and desogestrel, as well as contraceptive methods, such as vaginal rings, pills and patches.Combined hormonal pills, specifically desogestrel, and the progesterone-only medroxyprogesterone (Depo-Provera) injection were shown to have the highest risk for clots.“What’s new here are the updated risk estimates for newer formulations, such as low-dose oestrogen pills, vaginal rings, and implants, that haven’t been as thoroughly studied in large population-based cohorts,” said Harman Gailan Hassan Yonis, MD, a professor at Aalborg University Hospital in Denmark, who led the research.Yonis and his team analysed health data from nearl...
