The oestrogen 'sparing' effect of implanon: a case report and review.
This article presents a case study of the 'oestrogen sparing effect' of etonorgestrel especially high lighting its use in a patient with hypoestrogenism following long-term use of depomedroxyprogesterone acetate (DMPA); still wishing a long-term reversible method of contraception. There are studies demonstrating the effects of both DMPA and etonogestrel on estrogen status, but evidence is sparse, exploring the possibilities of usage of etonorgestrel following demonstration of hypo-oestrogenism with DMPA usage.
