BACKGROUND Epidemiological studies have shown that both the estrogen dose and progestogen type of oral contraceptives contribute to the increased risk of thrombosis in oral contraceptive users. Thrombin generation-based activated protein C (APC) sensitivity is a global test for the net prothrombotic effect of oral contraceptives and predicts the thrombotic risk. Our objective was to test the us...

Objective To estimate the potential impact of using hormonal contraceptives on rates of infection with human immunodeficiency virus type 1 (HIV-1) and on pregnancy rates by theoretically removing the use of hormonal contraceptives from a study population. Methods A prospective cohort study was conducted in 3704 HIVnegative women who were enrolled in two biomedical trials that tested two vaginal...

Hormonal contraceptives may be divided into combined estrogen-progestogen contraceptives (pills, skin patches, vaginal rings), progestogen-only contraceptives (pills, injections, implants, hormone spirals) and eme...

There is some evidence that endogenous progesterone and oestrogen levels influence asthma severity in females, but little is known about the effects of hormonal contraceptives. This study aimed to describe how females with asthma perceived the effects of hormonal contraceptives on symptom severity, and to describe the association between asthma severity and current use of hormonal contraceptive...

OBJECTIVES To improve access to contraceptives in remote and rural areas, sub-Saharan African countries are allowing community health workers (CHWs) to distribute hormonal contraceptives. Before offering hormonal contraceptives, CHWs must determine pregnancy status but often lack a reliable way to do so. No studies have evaluated the impact of providing CHWs with urine pregnancy test kits. We a...
