OBJECTIVE Depot medroxyprogesterone acetate (DMPA) reversibly reduces bone mineral density. To estimate the extent to which DMPA might increase fracture risk, we undertook a retrospective cohort study of fractures in DMPA users and users of non-DMPA contraceptives, using the General Practice Research Database. METHODS Eligible women were aged younger than 50 years at the qualifying first cont...

Young women using depot-medroxyprogesterone acetate (DMPA) contraception have low circulating estrogen and elevated synthetic progestin. Low estrogen and certain progestins have been shown to impact endothelial function even in young healthy women. The purpose of this study was to investigate how DMPA affects endothelial function and serum biomarkers of cardiovascular risk before and after acut...

INTRODUCTION HIV affects more women than any other life-threatening infectious agent, and most infections are sexually transmitted. HIV must breach the female genital tract mucosal barrier to establish systemic infection, and clinical studies indicate virus more easily evades this barrier in women using depot-medroxyprogesterone acetate (DMPA) and other injectable progestins for contraception. ...

We thank Dr Curry for an accurate summary of our study entitled ‘Use of depot medroxyprogesterone acetate contraception and incidence of bone fracture’. Nevertheless, we do not recommend more selective use of depot medroxyprogesterone acetate (DMPA) on account of fracture risk, as we believe that this recommendation would reduce access to an effective, safe contraceptive without actually reduci...

High discontinuation rates for depot medroxyprogesterone acetate (DMPA) in adolescents may contribute to the number of unintended pregnancies. Many cite vaginal bleeding as a reason for discontinuing DMPA use. In this study, we attempted to determine if treating DMPA-associated vaginal bleeding with monophasic oral contraceptive pills (OCP) raised continuation rates. A total of 131 patients who...

BACKGROUND Depot medroxyprogesterone acetate (DMPA) is a very popular hormonal contraceptive. Unpredictable bleeding disturbances are the main reasons for discontinuation and may be mediated through endometrial hormone receptors. This study was aimed to compare the expression of progesterone and estrogen receptors in the endometrium of bleeding DMPA users with that of amenorrhoeic DMPA users. ...
