Patricio Valdés Garc&i

Abstract

Although most studies show that breastfeeding delays the resumption of ovarian cyclicity and menses, Lactational Amenorrhea (LA) is its highly variable among different populations. Research has shown differences hormonal levels between fully nursing amenorrheic women and who those who recovered menses during the first six postpartum months: E2 levels or PRL/E2 ratio could be predictive of this condition. However, research about this phenomenon is not conclusive. Thus, this review article, through an analysis of secondary, summarizes the main factors involved in LA, considering its importance as a effective and natural contraception method.
