Impact of menstrual cycle phase and oral contraceptives on sleep and overnight memory consolidation.

ABSTRACT: Sleep spindles benefit declarative memory consolidation and are considered to be a biological marker for general cognitive abilities. However, the impact of sexual hormones and hormonal oral contraceptives (OCs) on these relationships are less clear. Thus, we here investigated the influence of endogenous progesterone levels of naturally cycling women and women using OCs on nocturnal sleep and overnight memory consolidation. Nineteen healthy women using OCs (M_Age  = 21.4, SD = 2.1 years) were compared to 43 healthy women with a natural menstrual cycle (follicular phase: n = 16, M_Age  = 21.4, SD = 3.1 years; luteal phase: n = 27, M_Age  = 22.5, SD = 3.6 years). Sleep spindle density and salivary progesterone were measured during an adaptation and an experiment
