Introduction: Sex steroids are important in female sexual function and dysfunction. Aim: To review the role of estrogens in the physiology and pathophysiology of female sexual functioning and the evidence for efficacy of estrogen therapy for female sexual dysfunction to update the previously published International Society of Sexual Medicine Consensus on this topic. Methods: Panel members reviewed the published literature using online databases for studies pertaining to estrogen in female sexual function and dysfunction. Attention was specifically given to clinical trials that had reported on sexual function outcomes in women treated with estrogen. Main Outcome Measures: Quality of data published in the literature and recommendations were based on the GRADES system. Results: Observational studies that have considered relationship factors and physical or mental health have reported that these factors contribute more to sexual functioning than menopausal status or estrogen levels. Few clinical trials have investigated estrogen therapy with sexual function as a primary outcome. The available data do not support systemic estrogen therapy for the treatment of female sexual dysfunction. Topical vaginal estrogen therapy improves sexual function in postmenopausal women with vulvovaginal atrophy (VVA) and is considered first-line treatment of VVA. Oral ospemifene, a selective estrogen receptor modulator, is effective for the treatment of VVA and might have independent systemic effects on female sexual function. Conclusion: For sexual problems, the treatment of VVA remains the most pertinent indication for estrogen therapy. When systemic symptoms are absent, estrogen therapy ideally can be administered by a vaginal preparation alone. Systemic estrogen therapy with combined estrogen and progestin in non-hysterectomized women is indicated for women who require treatment for vasomotor and/or other systemic estrogen deficiency symptoms. The improvement in well-being achieved by relief of vasomotor and other symptoms might improve libido in some women and abrogate further intervention. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 22-year-old woman with suffering with borderline personality disorder and polycystic ovary syndrome (PCOS). The case mentions that the woman has a history of sexual abuse by her stepfather and had multiple psychiatric hospitalizations for suicide attempts, ongoing self-harm and rapid mood swings. It also mentions that the patient received PCOS treatment of metformin, transdermal oestradiol and cyclical progesterone.

Increasing evidence from epidemiological, preclinical and clinical studies suggests that estrogens may exert psychoprotective effects in schizophrenia. Observations of gender differences in the onset and course of schizophrenia have prompted exploration of the effects of estrogen on the CNS. The aim of this paper is to provide an overview of different applications of adjunctive estrogen as a possible treatment for symptoms of schizophrenia in both men and women. Recent trials have suggested that estrogen augmentation therapy may be able to enhance the management of schizophrenia; however, the clinical application of estrogen as a treatment has been limited by potential side effects, the most worrying being breast and uterine cancer in women, and feminization in men. Selective estrogen receptor modulators (SERMs), however, may offer therapeutic benefits for both men and women with schizophrenia without posing threat to breast and uterine tissue and without feminizing effects. The use of estrogen opens up new possibilities for both men and women in the treatment of severe mental illnesses such as schizophrenia. With further preclinical and clinical research, it is hoped that this promising field of hormone modulation can continue to evolve and eventually be translated into real therapeutic potential.

Abstract: Transcranial direct current stimulation (tDCS) is a non‐invasive neuromodulatory technique. Responses to tDCS differ substantially between individuals. Sex hormones that modulate cortical excitability, such as estrogen, may contribute to this inter‐individual variability. The influence of estrogen on tDCS after‐effects has not yet been researched. This study aimed to investigate whether endogenous estrogen levels influence cortical response to tDCS. Data from 15 male and 14 female healthy adults were analyzed. Males completed one experimental session. Females completed two, one during the early follicular phase of the menstrual cycle when estrogen was low, one during the mid‐luteal phase when estrogen was high. Each session comprised 15‐min of anodal tDCS delivered to the left dorsolateral prefrontal cortex (DLPFC). Response to stimulation was assessed using electroencephalography with DLPFC transcranial magnetic stimulation (TMS) administered before, immediately after, and 20‐min after tDCS. Changes in amplitudes of N120 and P200 components of TMS‐evoked potentials over time were compared between males, women with low estrogen and women with high estrogen. Blood assays verified estrogen levels. Women with high estrogen demonstrated a significant increase in P200 amplitude at both time points and change over time was greater for the high estrogen group compared with males. No significant differences were observed between males and women with low estrogen, or between women with low and high estrogen. These preliminary results indicate that greater neuroplastic response to DLPFC tDCS is seen in highest compared with lowest estrogen states, suggesting that endogenous estrogen levels contribute to inter‐individual variability of tDCS outcomes.
