Abstract
Efficacy outcomes are only informative to the extent that they are validated. We examined the measurement properties of efficacy measures from the phase III ("RECONNECT") bremelanotide trials for hypoactive sexual desire disorder (HSDD) in women. Continuous efficacy outcomes, including a) the Female Sexual Function Index (FSFI) and its Desire domain (FSFI-D) and b) the Female Sexual Distress Scale-Desire/Arousal/Orgasm (FSDS-DAO) and its item assessing distress due to low desire (FSDS-DAO #13) have questionable, at best, validity evidence for women with HSDD. We found no validity evidence for previously published categorical treatment response outcomes from the RECONNECT trials. All efficacy results should be reported, but results on 8 of the 11 clinicaltrials.gov-specified efficacy outcomes were heretofore unpublished (including FSDS-DAO total score, FSFI total score, FSFI arousal domain, and items from the Female Sexual Encounter Profile-Revised). We analyzed these outcomes, upon which effect sizes ranged from nil to small. Several other continuous and categorical outcomes generated modest apparent benefits, though nearly all of these outcomes were likely derived post-hoc. Across RECONNECT trial data from two prior publications and the current study, bremelanotide's benefits are statistically modest and limited to outcomes for which scant evidence of validity among women with HSDD exists.

Abstract
Female sexual interest/arousal disorder (SIAD) is strongly influenced by interpersonal factors; however, there are no empirically-supported, couple-based sex therapy interventions for this disorder. This pre-registered study tested the feasibility of a cognitive-behavioral couple therapy (CBCT) intervention for SIAD. A sample of 19 couples in which a female partner was diagnosed with SIAD completed a 16-session CBCT intervention delivered online by therapists with PhD-level training in clinical psychology. Women with SIAD (Mage = 43.47, SD = 12.76) and their partners (Mage = 43.74, SD = 11.68) were in long-term relationships (M = 13.86, SD = 9.15). The CBCT sessions were video recorded and independently coded for treatment manual adherence and therapists reported on the completion of in-session and homework exercises. Participants completed measures of treatment satisfaction following the intervention as well as dyadic sexual desire (women with SIAD only) and sexual distress prior to treatment, post-treatment, and at 6 months follow-up. The therapists exhibited a high level of adherence to the treatment manual and couples had high rates of homework completion. Moreover, couples had low dropout rates, high attendance rates, and reported moderately high global treatment satisfaction and high satisfaction with virtual care. Women with SIAD reported large improvements in dyadic sexual desire and sexual distress from pre-treatment to post-treatment and pre-treatment to 6-month follow-up. Partners reported moderate and small improvements in sexual distress for post-treatment and 6-month follow-up, respectively. Results support the feasibility of an evidence-based CBCT intervention for SIAD and the need for a randomized clinical trial of the intervention.

Ventura-Aquino E, Ågmo A. The elusive concept of sexual motivation: can it be anchored in the nervous system? Front Neurosci 2023; 17:1285810.

Abstract
Sexual motivation is an abstract concept referring to the mechanisms determining the responsivity to sexually relevant stimuli. This responsivity determines the likelihood of producing a sexual response and the intensity of that response. Both responsivity to stimuli and the likelihood of making a response as well as the intensity of response are characteristics of an individual. Therefore, we need to assume that the concept of sexual motivation materializes in physiological mechanisms within the individual. The aim of the present communication is to analyze the requisites for the endeavor to materialize sexual motivation. The first requisite is to provide an operational definition, making the concept quantifiable. We show that parameters of copulatory behavior are inappropriate. We argue that the intensity of sexual approach behaviors provides the best estimate of sexual motivation in non-human animals, whereas the magnitude of genital responses is an exquisite indicator of human sexual motivation. Having assured how to quantify sexual motivation, we can then proceed to the search for physiological or neurobiological underpinnings. In fact, sexual motivation only manifests itself in animals exposed to appropriate amounts of gonadal hormones. In female rats, the estrogen receptor α in the ventrolateral part of the ventromedial nucleus of the hypothalamus is necessary for the expression of sexual approach behaviors. In male rats, androgen receptors within the medial preoptic area are crucial. Thus, in rats sexual motivation can be localized to specific brain structures, and even to specific cells within these structures. In humans, it is not even known if sexual motivation is materialized in the brain or in peripheral structures. Substantial efforts have been made to determine the relationship between the activity of neurotransmitters and the intensity of sexual motivation, particularly in rodents. The results of this effort have been meager. Likewise, efforts of finding drugs to stimulate sexual motivation, particularly in women complaining of low sexual desire, have produced dismal results. In sum, it appears that the abstract concept of sexual motivation can be reliably quantified, and the neurobiological bases can be described in non-human animals. In humans, objective quantification is feasible, but the neurobiological substrate remains enigmatic.

Abstract
Sexual motivation (desire) requires the simultaneous presence of an active central motive state and a stimulus with sexual significance. Once activated, sexual motivation leads to visceral responses and approach behaviors directed toward the emitter of the sexual stimulus. In humans, such behaviors follow cognitive evaluation of the context, including predictions of the approached individual's response. After successful approach and establishment of physical contact, manifest sexual activities may be initiated. Sexual interaction is associated with and followed by a state of positive affect in most animals, whereas aversive consequences may be experienced by humans. The affective reactions may become associated with stimuli present during sexual interaction, and these stimuli may thereby alter their incentive properties. Here we show how the incentive motivation model can be used to explain the origins and possible treatments of sexual dysfunctions, notably disorders of desire. We propose that associations formed between negative outcomes of sexual interaction and the salient stimuli, for example, the partner, underlies hypoactive desire disorder. Highly positive outcomes of sexual interaction enhance the incentive value of the stimuli present, and eventually lead to hyperactive sexual desire. Treatments aim to alter the impact of sexual incentives, mainly by modifying cognitive processes.

Abstract
Approximately 1 in 3 women experience low sexual desire. Despite this being a common concern, many women never seek professional help for their difficulties and will instead turn to online resources for information. We sought to address this need for digitally-accessible, evidence-based information on low sexual desire by creating a social media Knowledge Translation (KT) campaign called #DebunkingDesire. Our team led a 10 month social media campaign where our primary outcomes for the campaign were impressions, reach, and engagement. We generated over 300,000 social media impressions; appeared on 11 different podcasts that were listened to/downloaded 154,700 times; hosted and participated in eight online events; and attracted website users from 110 different countries. Over the course of the campaign we compiled lessons learned on what worked for disseminating our key messages and the importance of creating community for this population. These findings point to the utility of using social media as part of KT campaigns in sexual health, and to the importance of collaborating with patient partners and considering social media ads and podcasts to meet reach goals.

Expert Opin Pharmacother 2023; 24:135-143.

Abstract
INTRODUCTION Female sexual dysfunctions (FSDs) are common in women of any age and have a huge impact on quality of life and relationships. They have a multifaceted etiology limiting the development of pharmacotherapies with a high rate of effectiveness. Safety issues are also a concern. AREAS COVERED The authors report the most recent advances in pharmacotherapy for premenopausal and postmenopausal women with a main focus on hypoactive sexual desire disorders (HSDD) and associated sexual symptoms. Good levels of evidence have emerged for psychoactive agents, such as flibanserin and bremelanotide, as well as hormonal compounds (transdermal testosterone). The authors also report briefly on intravaginal DHEA (prasterone), local estrogen therapy (LET), and ospemifene to manage effectively vulvovaginal atrophy/genitourinary syndrome of menopause (VVA/GSM). In addition, they discuss promising therapeutic options highlighting the main reasons that hamper the availability of new labeled products. Finally, they include the importance of the multimodal approach to address FSDs. EXPERT OPINION Approved pharmacotherapies for FSD are limited. Validated multidimensional instruments and adequate objective measures of physical and mental responses to sexual external and internal incentives are mandatory to identify women suitable to chronic or on-demand treatments and to assess their pattern of response in research and practice.

Abstract
The spread of "cancel culture" related to sex and gender controversies in North America is examined as part of a larger movement to politicize sex research findings and certain sex and gender narratives as "correct" and "incorrect" from a so-called social justice standpoint. This binary is then used by academic administrators and empowered individuals or self-interest groups to reward or punish scholars for their viewpoints. The cases described by Meyer-Bahlburg, Lowrey, and Hooven are concrete examples of a growing "sexual McCarthyism" where empirical results are challenged by offended social justice "warriors" and embellished on social media into ad hominem attacks, to the point that it can damage-or even cancel-the careers of productive sexual scientists. This occurs largely out of fear on the part of academic administrators and lawyers charged with protecting the university from "brand damage" that might occur if the offending scholar is not dealt with. Sexual scientists are being vilified for research on sex differences, sex/gender assignment and subsequent causes for transitioning and/or de-transitioning, research that shows few or no untoward social or psychological effects of viewing pornography, research that debunks the notion of porn or sex "addiction," research showing the efficacy of medications to treat sexual desire disorders in women, research on "minor attracted persons" and even animal research that dares to show homologies to human sexual behavior. The silencing of empirical evidence and alternative viewpoints is contrary to the intellectual mission of universities and destructive to academic and political freedoms.
