“…Chronic periodontitis (CP) is an inflammatory condition of the tooth supporting structures (cementum, gingiva, periodontal ligament, and alveolar bone) that if left untreated progresses to bone destruction and tooth loss (Ram, Parthiban, Sudhakar, Mithradas, & Prabhakar, 2015). The relationship between female sex hormones (estrogens) and periodontal disease in women during puberty, pregnancy, and menopause, or taking oral contraceptives has been widely reported (Jafri, Bhardwaj, Sawai, & Sultan, 2015; Shapiro & Freeman, 2014); however, only a limited number of studies (Daltaban, Saygun, & Bolu, 2006; Kuraner et al, 1991; Orwoll et al, 2009; Samietz et al, 2016; Singh, Makker, Tripathi, Singh, & Gupta, 2011; Steffens, Wang, et al, 2015; Vittek, Kirsch, Rappaport, Bergman, & Southren, 1984; Vittek, Rappaport, Gordon, Munnangi, & Southren, 1979) have investigated the association between testosterone levels in men and CP. ElAttar, Lin, and Tira (1982) reported testosterone inhibitory properties in vitro in the cyclooxygenase pathway of arachidonic acid metabolism in gingiva.…”
