A comprehensive history of injection therapy for erectile dysfunction, 1982-2023

INTRODUCTION

Although oral phosphodiesterase 5 inhibitors represent a first choice and long-term option for about half of all patients with erectile dysfunction (ED), self-injection therapy with vasoactive drugs remains a viable alternative for all those who are not reacting or cannot tolerate oral drug therapy. This current injection therapy has an interesting history beginning in 1982.

OBJECTIVES

To provide a comprehensive history of self-injection therapy from the very beginnings in 1982 by contemporary witnesses and some members of the International Society for Sexual Medicine's History Committee, a complete history of injection therapy is prepared from eyewitness accounts and review of the published literature on the subject, as well as an update of the current status of self-injection therapy.

METHODS

Published data on injection therapy, as a diagnostic and therapeutic tool for ED, were reviewed thoroughly by PubMed and Medline research from 1982 until June 2023. Early pioneers and witnesses added firsthand details to this historical review. Therapeutic reports of injection therapy were reviewed, and results of side effects and complications were thoroughly reviewed.

RESULTS

The pioneers of the first hours were Ronal Virag (1982) for papaverine, Giles Brindley (1983) for cavernosal alpha-blockade (phentolamine and phenoxybenzamine), Adrian Zorgniotti (1985) for papaverine/phentolamine, and Ganesan Adaikan and N. Ishii (1986) for prostaglandin E1. Moxisylyte (thymoxamine) was originally marketed but later withdrawn. The most common side effect is priapism, with the greatest risk of this from papaverine, which has modified its use for therapy. Currently, prostaglandin E1 and trimixes continue to be the agents of choice for diagnostic and therapeutic use in ED. A recent agent is a mixture of a vasoactive intestinal polypeptide (aviptadil) and phentolamine.

CONCLUSIONS

After 40 years, self-injection therapy represents the medication with the highest efficacy and reliability rates and remains a viable option for many couples with ED. The history of this therapy is rich.

Immunohistochemical staining with CD117 and PGP9.5 of excised vestibular tissue from patients with neuroproliferative vestibulodynia

BACKGROUND

Neuroproliferative vestibulodynia (NPV), a provoked genital pain characterized by severe allodynia and hyperalgesia, is confirmed in excised vestibular tissue by immunohistochemical staining (>8 CD117-positive immunostained cells/100× microscopic field) rather than by hematoxylin and eosin staining.

AIM

In this study we sought to assess immunostaining of tissue samples obtained during vestibulectomy surgery and to correlate results with patient outcomes.

METHODS

Patients (n = 65) meeting criteria for NPV who underwent vestibulectomy during the period from June 2019 through December 2022 formed the study cohort. We performed assessment of pathology of vestibular tissues by use of immunohistochemical staining, including quantitation of mast cells by CD117 (mast cell marker) and nerve fibers by protein gene product (PGP) 9.5 (neuronal marker). We analyzed 725 photomicrographs of immunostained tissue sections (100× and 200×) by manual counting and computer-assisted histometry and correlated these data to clinical assessments.

OUTCOMES

Outcomes included density of CD117 and PGP9.5 immunostaining in the 1:00-11:00 o'clock and 12:00 o'clock vestibular regions, and patient-reported outcomes assessing sexual function, pain, distress, and symptom improvement.

RESULTS

All 65 NPV patients (median age 26 years), 45 with lifelong and 20 with acquired NPV, had severe pain documented by PROs and vulvoscopy and had >8 CD117-immunopositive cells/100× microscopic field. Median cell count values were similar in the 1:00-11:00 o'clock and 12:00 vestibular regions (28.5 and 29.5/100× field, respectively). Likewise, the marker) and nerve fibers by protein gene product (PGP) 9.5 (neuronal marker). We analyzed 725 photomicrographs of immunostained tissue sections (100× and 200×) by manual counting and computer-assisted histometry and correlated these data to clinical assessments.

OUTCOMES

Outcomes included density of CD117 and PGP9.5 immunostaining in the 1:00-11:00 o'clock and 12:00 o'clock vestibular regions, and patient-reported outcomes assessing sexual function, pain, distress, and symptom improvement.

RESULTS

All 65 NPV patients (median age 26 years), 45 with lifelong and 20 with acquired NPV, had severe pain documented by PROs and vulvoscopy and had >8 CD117-immunopositive cells/100× microscopic field. Median cell count values were similar in the 1:00-11:00 o'clock and 12:00 vestibular regions (28.5 and 29.5/100× field, respectively). Likewise, the median area of CD117 immunostaining was similar in both regions (0.69% and 0.73%). The median area of PGP9.5 immunostaining was 0.47% and 0.31% in these same regions. Pain scores determined with cotton-tipped swab testing were nominally higher in lifelong vs acquired NPV patients, reaching statistical significance in the 1:00-11:00 o'clock region (P < .001). The median score for the McGill Pain Questionnaire affective subscale dimension was also significantly higher in lifelong vs acquired NPV patients (P = .011). No correlations were observed between hematoxylin and eosin results and density of mast cells or neuronal markers. Of note, 63% of the patient cohort reported having additional conditions associated with aberrant mast cell activity.

CLINICAL IMPLICATIONS

The pathology of NPV is primarily localized to the vestibular epithelial basement membrane and subepithelial stroma with no visible vulvoscopic findings, making clinical diagnosis challenging.

STRENGTHS AND LIMITATIONS

Strengths of this study include the large number of tissues examined with what is to our knowledge the first-ever assessment of the 12:00 vestibule. Major limitations are specimens from a single timepoint within the disease state and lack of control tissues.

CONCLUSIONS

Performing immunohistochemical staining of excised vestibular tissue with CD117 and PGP9.5 led to histometric confirmation of NPV, indications that NPV is a field disease involving all vestibular regions, validation for patients whose pain had been ignored and who had experienced negative psychosocial impact, and appreciation that such staining can advance knowledge.

Princeton IV consensus guidelines: PDE5 inhibitors and cardiac health

BACKGROUND

In 1999, 1 year after the approval of the first oral phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (ED), the first Princeton Consensus Conference was held to address the clinical management of men with ED who also had cardiovascular disease. These issues were readdressed in the second and third conferences. In the 13 years since the last Princeton Consensus Conference, the experience with PDE5 inhibitors is more robust, and recent new data have emerged regarding not only safety and drug-drug interactions, but also a potential cardioprotective effect of these drugs.

AIM

In March 2023, an interdisciplinary group of scientists and practitioners met for the fourth Princeton Consensus Guidelines at the Huntington Medical Research Institutes in Pasadena, California, to readdress the cardiovascular workup of men presenting with ED as well as the approach to treatment of ED in men with known cardiovascular disease.

METHOD

A series of lectures from experts in the field followed by Delphi-type discussions were developed to reach consensus.

OUTCOMES

Consensus was reached regarding a number of issues related to erectile dysfunction and the interaction with cardiovascular health and phosphodiesterase-5 inhibitors.

RESULTS

An algorithm based on recent recommendations of the American College of Cardiology and American Heart Association, including the use of computed tomography coronary artery calcium scoring, was integrated into the evaluation of men presenting with ED. Additionally, the issue of nitrate use was further considered in an algorithm regarding the treatment of ED patients with coronary artery disease. Other topics included the psychological effect of ED and the benefits of treating it; the mechanism of action of the PDE5 inhibitors; drug-drug interactions; optimizing use of a PDE5 inhibitors; rare adverse events; potential cardiovascular benefits observed in recent retrospective studies; adulteration of dietary supplements with PDE5 inhibitors; the pros and cons of over-the-counter PDE5 inhibitors; non-PDE5 inhibitor therapy for ED including restorative therapies such as stem cells, platelet-rich plasma, and shock therapy; other non-PDE5 inhibitor therapies, including injection therapy and penile prostheses; the issue of safety and effectiveness of PDE5 inhibitors in women; and recommendations for future studies in the field of sexual dysfunction and PDE5 inhibitor use were discussed.

CLINICAL IMPLICATIONS

Algorithms and tables were developed to help guide the clinician in dealing with the interaction of ED and cardiovascular risk and disease.

STRENGTHS AND LIMITATIONS

Strengths include the expertise of the participants and consensus recommendations. Limitations included that participants were from the United States only for this particular meeting.

CONCLUSION

The issue of the intersection between cardiovascular health and sexual health remains an important topic with new studies suggesting the cardiovascular safety of PDE5 inhibitors.

Health-Care Resource Utilization and Treatment Patterns in Men with Erectile Dysfunction and Benign Prostatic Hyperplasia-Associated Lower Urinary Tract Symptoms in the United States: A Retrospective Database Study

Objective

To compare health-care resource utilization (HCRU) outcomes in patients with erectile dysfunction (ED) and benign prostatic hyperplasia-associated lower urinary tract symptoms (BPH-LUTS) treated with tadalafil or non-phosphodiesterase-5 inhibitor (PDE5i), adherence to and persistence with tadalafil by dose in the United States (US).

Methods

This was a noninterventional, real-world evidence study of men (aged ≥45 years) with ED and BPH-LUTS treated with tadalafil or non-PDE5i. The IQVIA US PharMetrics Plus claims database was used. Outcomes included all-cause and disease-specific HCRU over a 12-month follow-up. Persistence with and adherence to tadalafil were evaluated stratified by dose (10 or 20 mg as needed; 2.5 or 5 mg as once daily [OD]).

Results

The final sample comprised 11,351 tadalafil and 48,722 non-PDE5i patients. For all-cause and disease-specific HCRU, including prescription fills, physician office visits, emergency room visits, laboratory tests, radiology examinations, outpatient surgical services, ancillary services, hospitalizations, mean number of utilizations, and proportions of patients with one or more utilizations, were lower for tadalafil compared with non-PDE5i patients. For all-cause HCRU, proportions of patients with one or more emergency room visits (18.6% vs 21.7%, p<0.0001) and outpatient surgical visits (63.0% vs 68.8%, p<0.0001) were significantly lower for tadalafil compared with non-PDE5i patients. For disease-specific HCRU, the proportion with one or more disease-specific physician office visits (55.1% vs 91.4%), laboratory tests (34.8% vs 58.2%), outpatient surgery (24.3% vs 38.9%), or outpatient ancillary services (18.0% vs 29.8%) were significantly lower for tadalafil compared with non-PDE5i patients (all comparisons, p<0.0001). Mean persistence days (179.8 vs 61.2), proportion persistence (35.8% vs 6.5%), and mean adherence (0.5 vs 0.2) were higher for tadalafil OD doses than as-needed tadalafil doses.

Conclusion

Patients on tadalafil demonstrated less HCRU and higher persistence and adherence (OD versus as-needed tadalafil) than non-PDE5i patients, which demonstrates its benefit in the management of ED and BPH-LUTS in the US.

Reduction in genital sexual arousal varies by type of oral contraceptive pill

BACKGROUND

Although oral contraceptive pills (OCPs) have been associated with decrements in self-reported genital arousal and vaginal lubrication, 1,2 little is known about how these outcomes vary across types of OCPs.

AIM

The present study examined differences in physiological lubrication and vaginal blood flow, as well as rates of self-reported vulvovaginal atrophy and female sexual arousal disorder, among women using OCPs with varying androgenic properties.

METHODS

Participants in this study were 130 women: 59 naturally cycling control women, 50 women taking androgenic OCPs, and 21 women taking antiandrogenic OCPs. Participants watched sexual films while their sexual arousal responses were measured, completed questionnaires, and participated in a clinical interview.

OUTCOMES

Vaginal blood flow, vaginal lubrication, self-reported vulvovaginal atrophy, and female sexual arousal disorder were assessed.

RESULTS

Results indicated deficits in vaginal pulse amplitude and lubrication for women taking either form of OCP, with marked inhibitory effects found in women taking antiandrogenic OCPs. Rates of self-reported vulvovaginal atrophy and female sexual arousal disorder were also significantly greater in the antiandrogenic group compared with the control group.

CLINICAL IMPLICATIONS

It is recommended that prescribing clinicians consult patients on such physiological effects of OCPs.

STRENGTHS AND LIMITATIONS

To our knowledge, this was the first study to compare multiple measures of physiological sexual arousal across groups of women taking OCPs with varying hormonal profiles. Because all OCPs included in this study contained low doses of ethinylestradiol, we were able to identify the specific effects of the androgenic properties on women's sexual arousal responses. However, the self-administered lubrication test strip was subject to user error. Additionally, the generalizability of findings is limited by the largely heterosexual and college-aged sample.

CONCLUSION

Compared with naturally cycling women, women taking OCPs that contain antiandrogenic progestins experienced decreased vaginal blood flow and lubrication as well as higher rates of self-reported vaginal bleeding and female sexual arousal disorder.

Vestibular tissue changes following administration of intravaginal prasterone: a vulvoscopic open-label pilot study in menopausal women with dyspareunia

Background

Prasterone, an intravaginal dyspareunia treatment in menopausal women, improves vaginal health through intracellular conversion of dehydroepiandrosterone into androgens and estrogens. Phase 3 trials for prasterone showed significant improvement in vaginal tissue health and reduction of pain.

Aim

To assess vestibular changes with daily use of intravaginal prasterone in menopausal women with moderate to severe dyspareunia.

Methods

This open-label prospective pilot study was conducted over 20 weeks. It included 11 menopausal women (median age, 56 years) who were treated daily with intravaginal inserts of 6.5-mg prasterone and assessed monthly. During vulvoscopy, vestibular pain was assessed by cotton-tipped swab testing, and vestibular and vaginal health was independently assessed with the Visual Scale (VS). In addition, vulvoscopic photographs were obtained and assessed via the Vulvoscopic Genital Tissue Appearance (VGTA) scale to evaluate overall genital tissue health. Mean changes from baseline for genital tissue health and pain assessments were analyzed by repeated measures 1-way analysis of variance, followed by a Dunnett post hoc test. Sexual event diaries were completed and adverse events recorded.

Outcomes

Outcomes included indices of genital tissue health: pain assessment by cotton-tipped swab testing, VS of the vestibule and vagina, VGTA, and sexual event diary.

Results

Aggregate scores from the cotton-tipped swab test progressively improved, reaching statistical significance at week 16, which was maintained through week 20 (-7.27, P = .019). VS scores significantly improved from baseline by week 4 and were maintained through week 20 for the vestibule (-3.00, P = .004) and vagina (-4.00, P = .002). An overall 1607 vulvoscopic photographs were examined; all showed reduction in vestibular erythema and pallor at the end of the study. The mean change from baseline at week 20 for the VGTA score was -7.9 (P = .0016). Intercourse associated with pain was reduced from 81.3% of initiated events during the first month of the study to 8.3% during the last month. Sexual activities that were discontinued due to discomfort were reduced from 45.8% to 6.3%. No prasterone-related serious adverse events were reported.

Clinical Implications

Prasterone, a safe and effective intravaginal hormone treatment, significantly improves vestibular health parameters.

Strengths and Limitations

Strengths are the prospective study design and the use of multiple outcome measures to assess vestibular tissue health and pain associated with sexual activity. Limitations are the small study cohort and use of nonvalidated outcome measures.

Conclusion

Our findings suggest that intravaginal prasterone exerts biologic activity on the androgenic endodermal vestibule, as the medication passes from vagina to vestibule, resulting in amelioration of pain associated with sexual activity.

Characterizing the innervation of the vulvar vestibule and the immunohistochemical features of neuroproliferative vestibulodynia

BACKGROUND

Provoked vestibulodynia (PVD) is a chronic pain condition characterized by allodynia localized to the vulvar vestibule. The finding of increased densities of nerve fibers in the vestibular mucosa of patients with PVD has led to the identification of a neuroproliferative subtype. The etiology of PVD, including neuroproliferative vestibulodynia (NPV), is not fully understood. The gross and microscopic innervation of the vulvar vestibule remains incompletely described, despite the preliminary data supporting the role of peripheral innervation in PVD.

AIM

To characterize the gross anatomic and microscopic innervation of the vulvar vestibule through cadaveric dissection and immunohistochemistry.

METHODS

The pudendal nerve and inferior hypogastric plexus (IHP) were dissected using 6 cadaveric donors. Histology and immunohistochemistry were used to confirm patterns of innervation identified gross anatomically. Immunohistochemistry was performed on vestibulectomy specimens obtained from 6 patients diagnosed with NPV and compared with cadaveric vestibular tissues.

OUTCOMES

Outcomes included (1) dissection of pelvic innervation and (2) immunohistochemical localization of markers for the following: general innervation protein gene product 9.5 (PGP9.5), sensory innervation (calcitonin gene-related peptide), autonomic innervation (vasoactive intestinal polypeptide, tyrosine hydroxylase), neuroproliferation (nerve growth factor [NGF]), and immune activation (C-kit).

RESULTS

Perineal (pudendal) nerve branches were traced to the external wall of the vulvar vestibule. Some anatomic heterogeneity was observed in perineal nerve-branching patterns. Fibers from the IHP were identified in close proximity to the vulvar vestibule. Autonomic and sensory nerve fibers were identified in both patient and cadaveric vulvar vestibule samples. Patient samples were characterized by the proliferation of PGP9.5-positive nerve fibers and C-kit-positive mast cells, which were in proximity to neve bundles and showed coexpression with putative NGF-positive cells. NGF expression was localized to a subset of nerves, including those that demonstrated co-expression of sensory and autonomic nerve markers. Increased densities of autonomic fibers positive for vasoactive intestinal polypeptide and tyrosine hydroxylase were observed in 1 patient sample.

CLINICAL TRANSLATION

Heterogeneity in gross and microscopic patterns of innervation could explain variability in clinical response to treatment and should be used to inform future therapeutic interventions.

STRENGTHS AND LIMITATIONS

This study used a combination of approaches to elucidate the innervation of the vulvar vestibule, including in NPV. The small sample size is a limitation.

CONCLUSION

The vulvar vestibule contains both sensory and autonomic innervation, which may originate from the pudendal nerve and IHP. Our results support the existence of a neuroproliferative subtype that is characterized by the proliferation of sensory and autonomic nerve fibers and neuroimmune interactions.

Patient and provider perspectives on LEEP/LLETZ treatment and outcomes: an interview study

BACKGROUND

The loop electrosurgical excision procedure (LEEP) and large loop excision of the transformation zone (LLETZ) effectively treat cervical dysplasia, though some women have reported negative outcomes postoperatively (e.g., sexual dysfunction, psychosexual sequalae). There is insufficient understanding of patient experiences with these symptoms and perspectives from the providers who perform LEEP/LLETZ.

AIM

To characterize the perceptions and experiences of LEEP/LLETZ treatment from providers and patients, including whether there is a characteristic symptom profile of women who report negative outcomes.

METHODS

Patients who had LEEP/LLETZ treatment and reported negative outcomes and providers who perform LEEP/LLETZ completed semistructured interviews about their perceptions and experiences, which were coded through thematic analysis (NVivo 12; QSR International). Patients also completed an online survey assessing demographics, medical history, and sexual function.

OUTCOMES

Outcomes included perspectives generated from patient and provider interviews regarding LEEP/LLETZ procedural outcomes, including symptoms and experiences related to sexual functioning.

RESULTS

Perspectives and experiences gathered from patient and provider interviews revealed misaligned narratives surrounding LEEP/LLETZ outcomes and treatment. We identified 4 overarching themes encapsulating provider and patient responses: Expectations for Preoperative Consultation; Procedure Experiences; Attitudes; and Resources. Patients reported a unique symptom profile and negative outcome experiences, namely surrounding domains of sexual functioning: decreased physical sensations, orgasm response, and vaginal discharge, as well as loss of arousal, interest, and desire. Patients described changes to overall quality of life, with impacts to interpersonal relationships. Patients discussed preferring open-ended and directed questions to comprehensively elucidate negative outcomes. Provider narratives outlined the current process of care, emphasizing limited experiences with adverse outcomes (e.g., sexual issues) and the use of open-ended questions during counseling. Providers described an evolving intention to create comfortable clinical spaces. Regarding pre- and postoperative resources, patients described seeking support from online patient groups, and providers disclosed limitations to providing resources.

CLINICAL IMPLICATIONS

Evidence of discordance between patient and provider perspectives of LEEP/LLETZ reveals a need to reassess clinical practices surrounding this procedure at the level of discussions regarding informed consent, sexual function, and available resources.

STRENGTHS AND LIMITATIONS

This study is the first to examine patient and provider perspectives on LEEP/LLETZ treatment. Only patients who self-report negative outcomes were recruited, to elicit narratives from this specific subpopulation.

CONCLUSION

Results indicate a characteristic symptom profile of women who undergo LEEP/LLETZ and report negative outcomes and that the perceptions of patients and providers differ regarding several aspects of the treatment experience, supporting the need for directed open conversation and comprehensive pre- and postoperative sexual counseling.

Lumbar endoscopic spine surgery for persistent genital arousal disorder/genitopelvic dysesthesia resulting from lumbosacral annular tear-induced sacral radiculopathy

BACKGROUND

Persistent genital arousal disorder/genitopelvic dysesthesia (PGAD/GPD) is characterized by distressing, abnormal genitopelvic sensations, especially unwanted arousal. In a subgroup of patients with PGAD/GPD, cauda equina Tarlov cyst-induced sacral radiculopathy has been reported to trigger the disorder. In our evaluation of lumbosacral magnetic resonance images in patients with PGAD/GPD and suspected sacral radiculopathy, some had no Tarlov cysts but showed lumbosacral disc annular tear pathology.

AIM

The aims were 2-fold: (1) to utilize a novel multidisciplinary step-care management algorithm designed to identify a subgroup of patients with PGAD/GPD and lumbosacral annular tear-induced sacral radiculopathy who could benefit from lumbar endoscopic spine surgery (LESS) and (2) to evaluate long-term safety and efficacy of LESS.

METHODS

Clinical data were collected on patients with PGAD/GPD who underwent LESS between 2016 and 2020 with at least 1-year follow-up. LESS was indicated because all had lumbosacral annular tear-induced sacral radiculopathy confirmed by our multidisciplinary management algorithm that included the following: step A, a detailed psychosocial and medical history; step B, noninvasive assessments for sacral radiculopathy; step C, targeted diagnostic transforaminal epidural spinal injections resulting in a temporary, clinically significant reduction of PGAD/GPD symptoms; and step D, surgical intervention with LESS and postoperative follow-up.

OUTCOMES

Treatment outcome was based on the validated Patient Global Impression of Improvement, measured at postoperative intervals.

RESULTS

Our cohort included 15 cisgendered women and 5 cisgendered men (mean ± SD age, 40.3 ± 16.8 years) with PGAD/GPD who fulfilled the criteria of lumbosacral annular tear-induced sacral radiculopathy based on our multidisciplinary management algorithm. Patients were followed for an average of 20 months (range, 12-37) post-LESS. Lumbosacral annular tear pathology was identified at multiple levels, the most common being L4-L5 and L5-S1. Twenty-two LESS procedures were performed in 20 patients. Overall, 80% (16/20) reported improvement on the Patient Global Impression of Improvement; 65% (13/20) reported improvement as much better or very much better. All patients were discharged the same day. There were no surgical complications.

CLINICAL IMPLICATIONS

Among the many recognized triggers for PGAD/GPD, this subgroup exhibited lumbosacral annular tear-induced sacral radiculopathy and experienced long-term alleviation of symptoms by LESS.

STRENGTHS AND LIMITATIONS

Strengths include long-term post-surgical follow-up and demonstration that LESS effectively treats patients with PGAD/GPD who have lumbosacral annular tear-induced sacral radiculopathy, as established by a multidisciplinary step-care management algorithm. Limitations include the small study cohort and the unavailability of a clinical measure specific for PGAD/GPD.

CONCLUSION

LESS is safe and effective in treating patients with PGAD/GPD who are diagnosed with lumbosacral annular tear-induced sacral radiculopathy.

Safety and efficacy of fractional CO2 laser treatment to the vestibule: a randomized, double-blind, sham-controlled, prospective 3-site clinical study in women with vestibular pain

BACKGROUND

Data are limited regarding fractional CO2 laser as a nonhormonal treatment for vestibular pain.

AIM

We sought to perform what is, to our knowledge, the first multisite prospective randomized, double-blind, sham-controlled clinical trial to assess the safety and efficacy of fractional CO2 laser treatment to the vestibule in women with vestibular pain.

METHODS

Subjects (n = 70) meeting inclusion/exclusion criteria at each of 3 sites were randomized 2:1 to active or sham (zero energy) fractional CO2 laser treatment using the vestibular probe (SmartXide2 V2LR - MonaLisa Touch, DEKA, Florence, Italy). Subjects in each treatment arm received 3 treatments 4 weeks apart. At the initial follow-up (week 12), subjects were unblinded and those initially assigned to sham started active treatment.

OUTCOMES

Outcome measures included changes from baseline in sexual activity diaries and scores for the Vulvoscopic Genital Tissue Appearance Scale (VGTA), vestibular cotton-tipped swab testing, McGill Pain Questionnaire, Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and the O'Leary-Sant voiding and pain indices, the Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI).

RESULTS

After active treatment, VGTA scores significantly improved in 5 parameters. Pain associated with cotton-tipped swab testing was significantly reduced at weeks 4 through 16 (mean change from baseline -0.64 [95% CI, -0.79 to -0.50] and -1.31 [95% CI, -1.46 to -1.16], respectively). FSFI pain domain scores improved significantly at weeks 12 and 16 (mean change from baseline 0.925 [95% CI, 0.10-1.75] and 1.22 [95% CI, 0.40-2.05], respectively). FSFI total scores increased significantly at weeks 12 and 16 (mean change from baseline 6.24 [95% CI, 2.64-9.85] and 4.96 [95% CI, 1.36-8.57], respectively). FSDS-R scores decreased significantly at weeks 12 and 16 (mean change from baseline -5.84 [95% CI, -8.80 to -2.87] and -9.15 [95% CI, -12.11 to -6.18], respectively). ICSI scores decreased significantly at weeks 12 and 16 (mean change from baseline -0.91 [95% CI, -1.65 to -0.18] and -0.754 [95% CI, -1.49 to -0.02], respectively). ICPI scores decreased significantly at week 16 (mean change from baseline -0.99 [95% CI, -1.63 to -0.34]). In contrast, there were no significant changes in outcomes in the sham arm. No serious adverse events occurred.

CLINICAL IMPLICATIONS

Fractional CO2 laser treatment in women with vestibular pain resulted in improvement from baseline in multiple key outcome measures of vestibular health.

STRENGTHS AND LIMITATIONS

Strengths of the study were that it was a multisite prospective randomized double-blind, sham-controlled clinical trial that included multiple measures related to vestibular pain and sexual function. Limitations were the nonvalidated primary outcome measure and limited study cohort.

CONCLUSION

Fractional CO2 laser therapy is a safe and effective nonhormonal treatment for vestibular pain.

The prostate in women: an updated histological and immunohistochemical profile of the female periurethral glands and their relationship to an implanted midurethral sling

BACKGROUND

There is evidence of glandular tissue in the region of the anterior vaginal wall-female periurethral tissue (AVW-FPT) that has similar morphology and immunohistochemistry to the prostate in men. Surgical injury to this tissue has been suggested as a potential cause of sexual dysfunction following midurethral sling (MUS) procedures. However, the anatomy and embryology of these glands have not been fully resolved. This has led to difficulties in classifying this tissue as a prostate and defining its clinical significance related to MUS procedures.

AIM

To describe the histological and immunohistochemical characteristics of the female periurethral glands using markers of prostate tissue and innervation and to examine their anatomical relationships to an implanted MUS.

METHODS

Using gross and fine dissection, the AVW-FPT was dissected from 9 cadavers. Prior to dissection, 2 cadavers underwent simulation of the MUS procedure by a urogynecologist. Samples were paraffin embedded and serially sectioned. Immunohistochemistry was performed using markers of prostate tissue and innervation.

OUTCOMES

Redundant immunohistochemical localization of markers for prostatic tissue and innervation of the glandular tissue of the AVW-FPT, including the region of MUS implantation.

RESULTS

Female periurethral glands were immunoreactive for markers of male prostatic tissue, including prostate-specific antigen, androgen receptor, HOXB13, and NKX3.1. Markers of innervation (protein gene product 9.5, choline acetyl transferase, and vasoactive intestinal polypeptide) also localized to certain regions of the glandular tissue and associated blood supply. Surgical simulation of the MUS procedure demonstrated that some periurethral glands are located in close proximity to an implanted sling.

CLINICAL TRANSLATION

The AVW-FPT contains glandular tissue in the surgical field of MUS implantation. Iatrogenic damage to the female periurethral glands and the associated innervation during surgery could explain the negative impacts on sexual dysfunction reported following MUS procedures.

STRENGTHS AND LIMITATIONS

This is the first study to characterize the female periurethral glands using markers of prostatic tissue in concert with markers of general and autonomic innervation and characterize their anatomical relationships within the surgical field of MUS implantation. The small sample size is a limitation of this study.

CONCLUSION

We provide further evidence that the AVW-FPT contains innervated glands that are phenotypically similar to the male prostate and may share a common embryonic origin. The microscopic and immunohistochemical features of the periurethral glands may be indicative of their functional capacity in sexual responses. The location of these glands in the surgical field of MUS procedures underscores the clinical significance of this tissue.

The contribution of the cervix to sexual response: an online survey study

BACKGROUND

The role of the cervix in sexual response has been poorly studied, despite previous research indicating that some women experience pleasurable sexual sensations from cervical stimulation; given previous reports of sexual issues after cervix electrocautery, it is possible that cervical injury may compromise the role of the cervix in sexual functioning.

AIM

The aims of this study were to examine locations of pleasurable sexual sensations, to identify sexual communication barriers, and to investigate if cervical procedures are associated with negative impacts on sexual function.

METHODS

Women with (n = 72) and without (n = 235) a history of a gynecological procedure completed an online survey assessing demographics, medical history, sexual function (including locations of sexual pleasure and pain on diagrams), and barriers. The procedure group was divided into subgroups of those who had experienced a cervical (n = 47) or noncervical (n = 25) procedure. Chi-square analyses and t tests were conducted.

OUTCOMES

Outcomes included locations and ratings of pleasurable and painful sexual stimulation, as well as sexual function.

RESULTS

Over 16% of participants reported experiencing some pleasurable sexual sensations from the cervix. The gynecological procedure group (n = 72) reported significantly higher pain in the vagina and lower rates of pleasure in their external genitals, vagina, deep vagina, anterior and posterior vaginal walls, and clitoris vs the non-gynecological procedure (n = 235) group. The gynecological procedure group and the cervical procedure subgroup (n = 47) reported significant decreases in desire, arousal, and lubrication and increased avoidance of sexual activity due to vaginal dryness. The gynecological procedure group reported significant pain with vaginal stimulation, whereas the cervical subgroup identified significant pain with cervical and clitoral stimulation.

CLINICAL IMPLICATIONS

Cervical stimulation elicits some pleasurable sexual sensations for many women, and gynecological procedures that affect the cervix are associated with pain and sexual issues; thus, health care providers should counsel patients about the possibility of related sexual concerns.

STRENGTHS AND LIMITATIONS

This study is the first to examine locations of pleasure and pain and experiences of sexual pleasure and function in participants who underwent a gynecological procedure. A hybrid measure was used to assess sexual issues, including symptoms of dysfunction.

CONCLUSION

Results indicate an association between cervical procedures and sexual issues, supporting the need to inform patients of this possibility following cervical procedures.

Effects of Flibanserin on Subdomain Scores of the Female Sexual Function Index in Women With Hypoactive Sexual Desire Disorder

INTRODUCTION

Flibanserin treatment increases sexual desire and satisfying sexual events while decreasing distress in certain women diagnosed with acquired, generalized hypoactive sexual desire disorder (HSDD). Additional aspects of sexual function and the time course of response have not been fully characterized.

AIM

To evaluate changes in sexual function assessed by the subdomains of the Female Sexual Function Index (FSFI) in women with HSDD treated with flibanserin.

METHODS

FSFI data pooled from 3 pivotal flibanserin trials in premenopausal women (flibanserin = 1,165; placebo = 1,203) and FSFI data from one complete flibanserin trial in postmenopausal women (flibanserin = 432; placebo = 463) were subjected to post-hoc analyses. For each FSFI subdomain, least squares mean change from baseline was calculated at each assessment visit (treatment weeks 4, 8, 16, 24) and treatment groups were compared using analysis of covariance. Standardized effect size (Cohen's d) was also determined for each FSFI subdomain.

MAIN OUTCOME MEASURE

Changes from baseline in FSFI subdomains.

RESULTS

Compared to placebo, both premenopausal (P < .02) and postmenopausal (P < .045) patients in the flibanserin group reported significantly greater increases over baseline in the FSFI subdomain scores of desire, arousal, lubrication, orgasm, and satisfaction. In premenopausal patients, significant improvements were observed at the first assessment of response (week 4) and were maintained through week 24. In postmenopausal patients, significant improvements were observed at week 4 for desire and arousal, while significant improvements in lubrication, orgasm, and satisfaction were observed at week 8. At week 24, excluding the pain subdomain, standardized effect sizes ranged from 0.18 to 0.28 in the premenopausal cohort and 0.12 to 0.29 in the postmenopausal cohort. In both pre- and postmenopausal patients, improvements in pain were smaller and largely undifferentiated between treatment groups.

CLINICAL IMPLICATIONS

While variations in time to response should be taken into consideration, on average, the beneficial impact of flibanserin on overall sexual function occurs within the first month of treatment. The data also suggest that the response to flibanserin is sustained for the duration of treatment.

STRENGTHS AND LIMITATIONS

Sexual function assessments were performed in a large cohort of 2,368 premenopausal women and 895 postmenopausal women. However, the FSFI assesses changes over a 1-month period and time points earlier than 4 weeks could not be assessed.

CONCLUSION

These analyses suggest that assessment of benefit of flibanserin in HSDD should include improvements across all domains of sexual function, not only desire. Simon JA, Clayton AH, Goldstein I, et al.

Clinical Significance of Shortened Penile Length and Alterations in Penile Length Following Treatment for Peyronie's Disease

INTRODUCTION

Across many cultures, penis size has been associated with virility, and concerns about penile length are commonplace. Peyronie's disease (PD) is a known acquired cause of penile shortening.

OBJECTIVES

This paper describes the psychosocial impacts of penile length on men and their partners, both generally and in men with PD, and evaluates the effect of PD treatments (eg, collagenase clostridium histolyticum , surgery, mechanical therapy) on this outcome measure.

METHODS

A PubMed database search was performed for English language articles through July 2021. Main outcome measures were association of penile length with emotional well-being, selfesteem, and relationship satisfaction in men with PD, and change from baseline penile length after treatment.

RESULTS

Shortened penile length caused by PD can negatively impact patient and partner quality of life, including effects on body image, emotional well-being, sexual function, and interpersonal relationships. In men with PD, studies have demonstrated an association between loss of penile length and emotional problems, reduced satisfaction with sexual performance, poor self-esteem, depression, and relationship difficulties. Loss of penile length can frequently occur after surgery for PD (including plication, plaque incision/excision with grafting, and penile implant). Advanced surgical techniques may preserve/increase penile length, but the increased risks associated with these complex procedures must be carefully considered. Treatment with collagenase clostridium histolyticum does not appear to negatively impact penile length, and 5-year follow-up data suggest potential longterm posttreatment improvements in this outcome measure. Penile traction therapy, either alone or as adjunctive therapy, may increase penile length in men with PD, but nonadherence may limit improvement.

CONCLUSION

Changes in penile length are important to many men, particularly those with PD, and should be considered during PD treatment selection. Penile length should be measured objectively before and after treatment for PD and should be included as an outcome measure in future studies on treatment effectiveness.

Should We Call It a Prostate? A Review of the Female Periurethral Glandular Tissue Morphology, Histochemistry, Nomenclature, and Role in Iatrogenic Sexual Dysfunction

INTRODUCTION

There is evidence of glandular tissue within the region of the anterior vaginal wall-female periurethral tissue (AVW-FPT) having similar morphology and immunohistochemistry to the prostate in men and having physiological roles in the female sexual response (FSR). Whether this tissue should be called a prostate in women has been debated. Iatrogenic injury to structures of the AVW-FPT, including these glands and the associated neurovasculature, could be a cause of female sexual dysfunction (FSD).

OBJECTIVES

To consolidate the current knowledge concerning the glandular tissue surrounding the urethra in women, evidence was reviewed to address whether: (i) these glands comprise the prostate in women, (ii) they have specific functions in the FSR, and (iii) injury to the AVW-FPT and prostate has sexual dysfunction as a likely outcome.

METHODS

A literature review was conducted using keywords including female prostate, Skene's/paraurethral glands, periurethral tissue, Gräfenberg (G)-spot, female ejaculation, mid-urethral sling (MUS), and sexual dysfunction.

RESULTS

Histological and immunohistochemical studies of the glandular tissue surrounding the urethra support the existence of prostate in women. Evidence suggests this tissue may have physiologically and clinically relevant autonomic and sensory innervation, and during sexual arousal may contribute to secretions involved in ejaculation and orgasm. Gaps in knowledge relating to the functional anatomy, physiological roles, and embryological origins of this tissue have impeded the acceptance of a prostate in women. Injury to the innervation, vasculature, and/or glandular tissue within the surgical field of MUS implantation suggests iatrogenic sexual dysfunction is plausible.

CONCLUSIONS

Continuing to advance our understanding of the morphology, histochemistry, and physiologic capacity of this glandular tissue will clarify the characterization of this tissue as the "prostate" involved in the FSR, and its role in FSD following surgical injury.

A new oral testosterone (TLANDO ® ) treatment regimen without dose titration requirement for male hypogonadism

Background

Male hypogonadism (testosterone level < 300 ng/dl) is a clinical syndrome that results from failure of the testis to produce physiological levels of testosterone. Most marketed testosterone replacement therapy products often require multiple dose adjustment clinic visits to achieve the desired, eugonadal testosterone levels.

Objective

To evaluate the efficacy and safety of a novel oral testosterone undecanoate therapy for the treatment of hypogonadism.

Material and methods

Ninety‐five (N = 95) hypogonadal men were enrolled in this open‐label, single‐arm, multicenter study in the United States (NCT03242590). Subjects received 225 mg of oral testosterone undecanoate (TLANDO) twice a day for 24 days without dose adjustment. Primary efficacy was percentages of subjects who achieved mean 24‐h testosterone levels within the eugonadal range and secondary efficacies were evaluated based on the upper limit of lab normal range of testosterone concentration.

Results

Subjects enrolled were on average age of 56 years, with about 17% of subjects older than 65 years. The mean body mass index was 32.8 kg/m². The baseline mean total testosterone values were below the normal range (202 ± 74 ng/dl). Post‐treatment with 450 mg testosterone undecanoate daily dose without dose adjustment, 80% of subjects (95% confidence interval of 72%–88%) achieved a testosterone Cavg in the normal range and restored testosterone levels to mean testosterone Cavg of 476 ± 184 ng/dl at steady state. Testosterone restoration was comparable to other approved testosterone replacement therapy products. TLANDO was well tolerated with no deaths, no drug‐related serious adverse events, and no hepatic adverse events.

Discussion and conclusions

TLANDO restored testosterone levels to the normal range in the majority of hypogonadal males. This new oral testosterone replacement therapy can provide an option for no‐titration oral testosterone replacement therapy. This therapy has the potential to improve patient compliance in testosterone replacement therapy.

Ovarian stimulation for fertility treatments and risk of breast cancer: a matched cohort study

STUDY QUESTION

Is there a difference in the breast cancer risk among women who underwent ART treatments compared to those who underwent medically assisted reproduction (MAR) infertility treatments or women of reproductive age in the general population?

SUMMARY ANSWER

The risk of breast cancer among women treated by ART was similar to the risk among women treated by MAR and women who did not undergo fertility treatments.

WHAT IS KNOWN ALREADY

Studies investigating breast cancer risk in women who have undergone fertility treatments have provided conflicting results.

STUDY DESIGN, SIZE, DURATION

A retrospective, population-based cohort study included women who underwent ART or MAR treatments and women who did not undergo fertility treatments from 1994 to 2019.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Women who underwent ART were matched one to one with women who underwent MAR treatments and one to one with woman from the general population of reproductive age, by year of birth and year of first delivery or nulliparity status. MAR women were also matched to ART women by treatment initiation calendar year. All included women were members of Maccabi Healthcare Services. Data regarding demographics, fertility treatments, BRCA mutation and possible confounders were obtained from the computerized database of electronic health records. The incidence of breast cancer after fertility treatments was compared to the matched controls.

MAIN RESULTS AND THE ROLE OF CHANCE

Of 8 25 721 women of reproductive age, 32 366 women who underwent ART were matched with patients treated by MAR (n = 32 366) and 32 366 women of reproductive age. A total of 984 women (1.0%) were diagnosed with breast cancer (mean follow-up period, 9.1 ± 6.3 years; interquartile range [IQR], 3.8-13.7 years). The incidence rates of breast cancer per 10 000 person-years were 11.9 (95% CI, 10.7-13.3), 10.7 (95% CI, 9.6-11.9) and 10.7 (95% CI, 9.6-12.0) in the ART group, MAR group and general population, respectively. The crude risk for breast cancer was similar in the ART group compared with the general population (hazard ratio (HR) = 1.10, 95% CI, 0.94-1.28) and in the ART group compared with the MAR group (HR = 1.00, 95% CI, 0.86-1.16). Further adjustment for age, BMI, smoking, socioeconomic status and parity did not substantially impact the hazard rates for breast cancer (ART vs general population: HR = 1.10, 95% CI, 0.94-1.28; ART vs MAR: HR = 0.99, 95% CI, 0.85-1.16). Among women diagnosed with breast cancer, the prevalence of BRCA1/2 mutations and tumour staging did not differ between the ART, MAR and general population groups. Among women who underwent ART, no correlation was found between breast cancer and the number of ART cycles or the use of recombinant medications or urine-derived medications.

LIMITATIONS, REASONS FOR CAUTION

The mean age of women at the end of follow-up was only 42 years thus the study was not powered to detect potential differences in the risk of postmenopausal breast cancer. In addition, we did not sub-classify the exposed patients by the reason for infertility.

WIDER IMPLICATIONS OF THE FINDINGS

Breast cancer incidence following ART was comparable to that in the general population or following MAR. Women undergoing fertility treatments and their clinicians may be reassured about the safety of assisted reproduction technologies in terms of premenopausal breast cancer risk.

Diagnostic criteria for enduring sexual dysfunction after treatment with antidepressants, finasteride and isotretinoin

BACKGROUND:

A set of enduring conditions have been reported in the literature involving persistent sexual dysfunction after discontinuation of serotonin reuptake inhibiting antidepressants, 5 alpha-reductase inhibitors and isotretinoin.

OBJECTIVE:

To develop diagnostic criteria for post-SSRI sexual dysfunction (PSSD), persistent genital arousal disorder (PGAD) following serotonin reuptake inhibitors, post-finasteride syndrome (PFS) and post-retinoid sexual dysfunction (PRSD).

METHODS:

The original draft was designed using data from two published case series (Hogan et al., 2014 and Healy et al., 2018), which represent the largest public collections of data on these enduring conditions. It was further developed with the involvement of a multidisciplinary panel of experts.

RESULTS:

A set of criteria were agreed upon for each of the above conditions. Features of PSSD, PFS and PRSD commonly include decreased genital and orgasmic sensation, decreased sexual desire and erectile dysfunction. Ancillary non-sexual symptoms vary depending on the specific condition but can include emotional blunting and cognitive impairment. PGAD presents with an almost mirror image of unwanted sensations of genital arousal or irritability in the absence of sexual desire. A new term, post-SSRI asexuality, is introduced to describe a dampening of sexual interest and pleasure resulting from a pre-natal or pre-teen exposure to a serotonin reuptake inhibitor.

CONCLUSIONS:

These criteria will help in both clinical and research settings. As with all criteria, they will likely need modification in the light of developments.

The Use of Pramipexole to Treat Persistent Genital Arousal Disorder: A Case Report

INTRODUCTION

Persistent Genital Arousal Disorder (PGAD) is defined as "spontaneous, intrusive, and unwanted genital arousal (tingling, throbbing, pulsating) in the absence of sexual interest and desire" and traditionally causes marked distress, embarrassment and shame. PGAD may be caused by starting, discontinuing, or making adjustments in certain antidepressants or other medications.

AIM

To report the case of a 36- year- old woman with PGAD, likely due to changes in her psychiatric medications, who was treated with pramipexole and experienced improvement in her PGAD symptoms.

METHODS

Patient self-report and literature review. Written informed consent was obtained from the patient.

MAIN OUTCOME MEASURE

Improvement in PGAD symptoms.

RESULTS

Patient reported improvement in her symptoms by "90%" on a low dose of pramipexole, although higher doses exacerbated her symptoms.

CONCLUSIONS

It is likely that an effective treatment window exists for the treatment of PGAD with drugs that possess the ability to exert their control of dopaminergic transmission. This includes direct acting receptor agonists like pramipexole, which produce feedback inhibition. Limitations to their efficacy then involve co-treatments that counteract their ability to exert a dampening effect on hyperstimulated dopamine transmission. It is recommended that clinicians be aware of drugs taken by patients to treat psychiatric disorders that could induce PGAD symptoms, drugs recently discontinued where a rebound effect could lead to PGAD symptoms, and drug mechanisms that could counteract the effect of treatments for PGAD.

Immunohistochemical Investigation of Autonomic and Sensory Innervation of Anterior Vaginal Wall Female Periurethral Tissue: A Study of the Surgical Field of Mid-Urethral Sling Surgery Using Cadaveric Simulation

BACKGROUND

Female sexual dysfunction, including female orgasm disorder, has been reported following mid-urethral sling (MUS) surgery to treat bothersome stress urinary incontinence. Anterior vaginal wall-female periurethral tissue (AVW-FPT) likely contains autonomic and sensory innervation involved in the female sexual response, and injury to these nerves may result from MUS implantation.

AIM

To characterize, using fresh cadaveric tissue, autonomic and sensory nerves in AVW- FPT using immunohistochemistry (IHC), and to assess their proximity to an implanted MUS.

METHODS

AVW-FPT was excised following careful dissection from four fresh cadavers. Prior to dissection, one cadaver underwent simulation of the MUS procedure by a urogynegologist, using a fascial sling. All samples were paraffin embedded, sectioned, and stained with hematoxylin. Serial sectioning and IHC were performed to identify nerves. IHC markers were used to characterize the sensory and autonomic innervation.

OUTCOMES

IHC localization of autonomic and sensory nerve markers consistent with neural tissue within the region of MUS implantation.

RESULTS

IHC of AVW-FPT using protein gene product 9.5 (PGP9.5), a general nerve stain, revealed innervation throughout the region targeted by the MUS implantation. More specifically, immunoreactivity for both autonomic (tyrosine hydroxylase, TH) and sensory (Na_v1.8 and S100ß) nerves were found in close proximity (<1 mm) to the implanted MUS. In addition, a subset of S100ß positive nerves also showed immunoreactivity for calcitonin gene-related peptide (CGRP). Combining the IHC findings with the surgical simulation of the MUS implantation revealed the potential for damage to both autonomic and sensory nerves as a direct result of the MUS procedure.

CLINICAL TRANSLATION

The identified autonomic and sensory nerves of the AVW-FPT may contribute to the female sexual response, and yet are potentially negatively impacted by MUS procedures. Given that surgeries performed on male genital tissue, including the prostate, may cause sexual dysfunction secondary to nerve damage, and that urologists routinely provide informed consent regarding this possibility, urogynaecologists are encouraged to obtain appropriate informed consent from prospective patients undergoing the MUS procedure.

STRENGTHS & LIMITATIONS

This is the first study to characterize the sensory and autonomic innervation within the surgical field of MUS implantation and demonstrate its relationship to an implanted MUS. The small sample size is a limitation of this study.

CONCLUSION

The present study provides evidence of potential injury to autonomic and sensory innervation of AVW-FPT as a consequence of MUS implantation, which may help explain the underlying mechanisms involved in the reported post-operative female sexual dysfunction in some women.

TLANDO, a Novel Oral TRT, Improves Sexual and Mental Domain Outcomes in Hypogonadal Men

Male hypogonadism is characterized by symptoms and deficiency (&lt;300 ng/dL) in levels of in total testosterone (TT), a critical hormone for sexual, cognitive, and body function and development. TLANDO, a testosterone undecanoate (TU) comprising lymphatically delivered oral testosterone replacement therapy (TRT) option not requiring dose titration, treatment has demonstrated effective restoration in hypogonadal men of TT levels to the eugonadal range in multiple clinical studies. TLANDO therapy resulted in decreased sex hormone binding globulin with increased free testosterone (FT). TLANDO’s unique delivery system enables consistent restoration of TT regardless of meal fat content. Moreover, TLANDO has shown potential to improve liver health through resolution of fatty liver disease in hypogonadal men and is not known to have any adverse liver effects. However, it is unclear if fixed dose TLANDO therapy without dose adjustment improves symptoms of psychosexual functions. The objective is to assess key sexual and mental domain Patient Reported Outcomes (PRO) post 52 weeks of treatment using TLANDO on the to-be-marketed dosing regimen in comparison with a widely used topical TRT, Androgel 1.62%. Data analysis was performed in in hypogonadal males post TLANDO treatment without dose adjustment, and in patients on the active control from a randomized, multi-center, open label, active controlled 52-week trial (SOAR, NCT02081300). Sexual and mental domain function PROs were measured at baseline (BL) and end of study (EOS) using Psychosexual Daily Questionnaire (PDQ) and Short Form (SF)-36 surveys and compared between TLANDO and active control. Post treatment with TLANDO dosing regimen not requiring dose titration, key sexual domain function PROs at week 52 were significantly (p&lt;0.05) improved from BL: positive mood (BL:4.5 vs EOS:5.1, p&lt;0.001), negative mood (1.8 vs 1.4, p&lt;0.01), overall sexual desire (2.5 vs 3.7, p&lt;0.001), sexual activity (2.5 vs 4.0, p&lt;0.001), highest pleasure with partner (2.0 vs 2.8, p=0.06), highest pleasure without partner (1.8 vs 2.4, p&lt;0.05), weekly maintained erection (3.3 vs 4.5, p&lt;0.001), and weekly full erection % (50.5% vs 68.9%, p&lt;0.001). Most sexual and mental function PROs were comparable to Androgel 1.62. TLANDO therapy was well tolerated through 52 weeks of treatment exposure. In conclusion, TLANDO, a novel easy to use and prescribe TRT not requiring dose titration, demonstrated improvement in sexual and mental PROs, a significant unmet need in hypogonadal males. Further placebo-controlled studies are warranted to better elucidate these improvements.

Efficacy and Safety of TLANDO, A Novel Oral Easy to Prescribe and Use TRT Option

Most widely used testosterone replacement therapy (TRT) products can be inconvenient and cumbersome topical and invasive injectable requiring dose adjustments to attain efficacy. In a pivotal study, a recently approved oral TRT only 26% of patients did not require any dose adjustment. Typically, patients start on a sub-therapeutic dose with gradual dose increases to attain efficacy resulting in additional visit(s) to clinic and pharmacy. Physician research data (N=402) suggested it typically takes 3-6 months of titrations to reach an efficacious dose for majority of patients, a significant barrier in effecting a switch without a period of “efficacy gap”. The requirement of additional visit(s) presents significant challenges for new and current patients desiring to start and to switch to a convenient TRT option, especially in the current COVID-19 pandemic. Recent reports suggest increase of disease severity/mortality in men with low testosterone is possibly due to underlying co-morbidities commonly associated with male hypogonadism. There remains a need for an effective, safe, and easy to use and prescribe product that does not require dose titration. TLANDO is a “triglyceride-free” oral single strength TRT with single dose designed to lymphatically deliver effective and safe levels of testosterone regardless of meal fat content. Moreover, dose titration is prone to some inherent titration decision errors and requires understanding of often complex titration rules. The objective is to assess whether TLANDO, an oral TRT without requiring dose titration, safely restores effective testosterone (T) levels in hypogonadal men. An open-label, single-arm, multicenter study (NCT03242590) was performed with TLANDO in hypogonadal males (N=95). Subjects received orally 225 mg twice a day testosterone undecanoate (TU) for 24 days without dose adjustment. Efficacy was evaluated by % of subjects who achieved daily T Cavg within the eugonadal range. Using 450mg daily dose without dose adjustment, 80% of subjects (95% CI of 72% to 88%) achieved a T Cavg in the normal range and safely restored with mean T Cavg of 476±184 ng/dL post steady state. T restoration was comparable to other non-oral TRT products. TLANDO was well tolerated with no deaths, no drug-related severe AEs, and no hepatic AEs. In conclusion, effective T restoration using TLANDO, an easy to use and prescribe oral TRT option, was confirmed. Minimal AEs were reported with no hepatic AEs. Upon approval, TLANDO will be the first convenient TRT option without requiring dose adjustments; therefore, enabling selection of an efficacious dose from the start of therapy. TLANDO is well suited for new or existing TRT patients desiring a convenient oral option.

International Society for the Study of Women's Sexual Health Clinical Practice Guideline for the Use of Systemic Testosterone for Hypoactive Sexual Desire Disorder in Women

AIM

To provide a clinical practice guideline for the use of testosterone including identification of patients, laboratory testing, dosing, post-treatment monitoring, and follow-up care in women with hypoactive sexual desire disorder (HSDD).

METHODS

The International Society for the Study of Women's Sexual Health appointed a multidisciplinary panel of experts who performed a literature review of original research, meta-analyses, review papers, and consensus guidelines regarding testosterone use in women. Consensus was reached using a modified Delphi method.

OUTCOMES

A clinically useful guideline following a biopsychosocial assessment and treatment approach for the safe and efficacious use of testosterone in women with HSDD was developed including measurement, indications, formulations, prescribing, dosing, monitoring, and follow-up.

RESULTS

Although the Global Position Statement endorses testosterone therapy for only postmenopausal women, limited data also support the use in late reproductive age premenopausal women, consistent with the International Society for the Study of Women's Sexual Health Process of Care for the Management of HSDD. Systemic transdermal testosterone is recommended for women with HSDD not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. Current available research supports a moderate therapeutic benefit. Safety data show no serious adverse events with physiologic testosterone use, but long-term safety has not been established. Before initiation of therapy, clinicians should provide an informed consent. Shared decision-making involves a comprehensive discussion of off-label use, as well as benefits and risks. A total testosterone level should not be used to diagnose HSDD, but as a baseline for monitoring. Government-approved transdermal male formulations can be used cautiously with dosing appropriate for women. Patients should be assessed for signs of androgen excess and total testosterone levels monitored to maintain concentrations in the physiologic premenopausal range. Compounded products cannot be recommended because of the lack of efficacy and safety data.

CLINICAL IMPLICATIONS

This clinical practice guideline provides standards for safely prescribing testosterone to women with HSDD, including identification of appropriate patients, dosing, and monitoring.

STRENGTHS AND LIMITATIONS

This evidence-based guideline builds on a recently published comprehensive meta-analysis and the Global Position Statement endorsed by numerous societies. The limitation is that testosterone therapy is not approved for women by most regulatory agencies, thereby making prescribing and proper dosing challenging.

CONCLUSION

Despite substantial evidence regarding safety, efficacy, and clinical use, access to testosterone therapy for the treatment of HSDD in women remains a significant unmet need.
