“…Hormonal contraceptives (HC), and in particular combined oral contraceptives (COC), have been linked to changes in brain structure and function ( Porcu et al, 2019 ; Brønnick et al, 2020 ; Rehbein et al, 2021 ) and associated with behavioral changes, including women’s mental health ( Sundström-Poromaa, 2021 ), cognitive performance ( Warren et al, 2014 ), mate preferences ( Alvergne and Lummaa, 2010 ), and social and emotional functioning ( Montoya and Bos, 2017 ; Lewis et al, 2019 ). Considering the wide-spread use of HC, societal consequences have been intensively discussed ( Alvergne and Lummaa, 2010 ; Montoya and Bos, 2017 ; Sundström-Poromaa, 2021 ). Given the estrogenic actions of ethinylestradiol and other synthetic estrogens ( Stanczyk et al, 2013 ), as well as the progestogenic, androgenic, anti-androgenic, or mineralocorticoid properties of the various synthetic progestins contained in HC ( Sitruk-Ware, 2006 ; Griksiene et al, 2022 ), the described effects appear plausible.…”
