Does progesterone cause venous thromboembolism?

Collectively, progestin-only contraceptives were not associated with an increased risk of venous thromboembolism compared with non-users in a limited number of observational studies. In the subset of women in this analysis prescribed injectable progestins, there was an approximate twofold increase in thrombotic risk.
