The comorbidity between female sexual dysfunction (FSD) and major depressive disorder (MDD) is well documented; however, the mechanism(s) underlying the relationship between these disorders has not been defined. The literature has associated the adrenal hormones cortisol and dehydroepiandrosterone (DHEA) with FSD and MDD, suggesting a biological mechanism that may elucidate the comorbidity between these disorders. Based on evidence pointing to a high cortisol/DHEA ratio (C/D Ratio) in MDD and low DHEA in FSD, this study investigated if the potential association between a high C/D Ratio and FSD would be greater for women with a history of MDD when compared to women without a history of MDD. Two groups of women (MDD history group; control group), each with a range of sexual function, collected saliva samples, completed questionnaires, and participated in a clinical interview and a psychophysiological assessment. Results did not support the hypothesis that the relationship between the C/D Ratio and sexual function would be greater for women with a history of MDD. Relevant to the effects of hormones on sexual function, a higher C/D Ratio was associated with lower frequency of sexual activity and lower sexual assertiveness. Results also showed DHEA positively associated with overall frequency of sexual activity, while cortisol was associated with lower subjective assessment of sexual desire/arousal prior to erotic stimuli. Lastly, secondary analyses revealed a positive association between DHEA and frequency of sexual activity, which was mediated by women's sexual desire. These results suggest that the effects of the C/D Ratio on FSD are not associated with a history of MDD. Results also point to contrasting roles for C/D Ratio and DHEA in FSD. In particular, a high C/D Ratio may have inhibitory effects on frequency of sexual activity and sexual assertiveness, while high DHEA may have facilitatory effects on sexual activity frequency through heightened sexual desire. Lastly, high cortisol may predispose women to have a negative assessment of sexual stimuli. These findings contribute to a further understanding of the roles of the C/D Ratio, DHEA, and cortisol in female sexuality and offer support for future studies investigating the role of these hormones in FSD.

Since the late 1990s, researchers have reported a high degree of sexual dysfunction among American women that is associated with significant negative consequences (e.g., reduced quality of life and sexual satisfaction). In addition, sexual satisfaction is a primary factor in marital stability. Because of the widespread impact on both individual well-being and marital relationships, female sexual dysfunction is a significant public health problem. Most research has supported the predominance of psychocultural factors in women's sexual issues. Authenticity, defined by Kernis and Goldman as acting in accord with one's natural inclinations, is associated with increased well-being, but researchers have often overlooked it in the literature on female sexual dysfunction. This study, guided by Kernis and Goldman's authenticity theory, argued that gender culture impairs the ability of women to be authentic in the sexual realm, and, thereby, increases the risk of sexual problems. The purpose of this research study was to examine the relationship between authenticity, as measured by The Authenticity Inventory, Version 3, and female sexual dysfunction, as measured by The Female Sexual Function Index and The Female Sexual Distress Scale, Revised, in a group of 55 women attending an online university. The hypothesis was that women with higher rates of dysfunction and/or distress would score lower on authenticity. The results from a regression analysis did not reach significance and failed to confirm the hypothesis; however, there was an association between distress and dysfunction. This study contributes to social change by examining an association between authenticity and female sexual dysfunction that is of help to researchers and therapists working with women in the area of sexual health.
