Analysis of hsa-miR-19a-3p and hsa-miR-19b-3p modulation and phosphodiesterase type 5 expression in the vaginal epithelium of premenopausal women with genital arousal disorder.

BACKGROUND: Few studies have investigated the role of the phosphodiesterase type 5A (PDE5A) isoenzyme in female genital tissue disorders, exclusively taken from cadavers, as well as the epigenetic mechanisms responsible for the regulation of PDE5A levels. AIM: The aim was to study the in vivo association between microRNA (miRNA) expression and the expression levels of PDE5A in women with female genital arousal disorder (FGAD) compared with healthy women. METHODS: Premenopausal women affected by FGAD (cases) and sexually healthy women (control group) underwent microbiopsy of the periclitoral anterior vaginal wall for the collection of tissue samples. Computational analyses were preliminarily performed in order to identify miRNAs involved in the modulation of PDE5A by using miRNA-messenger RNA interaction prediction tools. Differences in the expression levels of miRNAs and PDE5A were finally investigated in cases and control subjects by using the droplet digital polymerase chain reaction amplification system and stratifying women considering their age, number of pregnancies, and body mass index. OUTCOMES: Expression levels of miRNAs were able to target PDE5A and the tissue expression in women with FGAD compared with healthy women. RESULTS: The experimental analyses were performed on 22 (43.1%) cases and 29 (56.9%) control subjects. Two miRNAs with the highest interaction levels with PDE5A, hsa-miR-19a-3p (miR-19a) and hsa-miR-19b-3p (miR-19b), were identified and selected for validation analyses. A reduction of the expression levels of both miRNAs was observed in women with FGAD compared with the control subjects (P < .05). Moreover, PDE5A expression levels were higher in women with FGAD and lower in women without sexual dysfunctions (P < .05). Finally, a correlation between body mass index and the expression levels of miR-19a was found (P < .01). CLINICAL IMPLICATIONS: Women with FGAD had higher levels of PDE5 compared with control subjects; therefore, the administration of PDE5 inhibitors (PDE5 inhibitors) could be useful in women with FGAD. STRENGTHS AND LIMITATIONS: The strength of the current study was to analyze genital tissue obtained in vivo from premenopausal women. A limitation was to not investigate other factors, including endothelial nitric oxide synthetases, nitric oxide, and cyclic guanosine monophosphate. CONCLUSION: The results of the present study indicate that the modulation of selected miRNAs could influence PDE5A expression in genital tissues in healthy women or in those with FGAD. Such findings further suggest that treatment with PDE5 inhibitors, as a modulator of PDE5A expression, could be indicated for women with FGAD.

Primary vulvar endometriosis in postmenopausal woman: a case report and review of the literature.

Endometriosis is a benign, estrogen-dependent condition that commonly affects women during the reproductive age. Postmenopausal endometriosis is a rare condition because of the absence of estrogenic hormone production. Furthermore, extrapelvic endometriosis is a rare and complex phenomenon. For this reason, it is usually a misdiagnosed disease. An 84-year-old female patient with no medical history of endometriosis or dysmenorrhea and no hormone replacement therapy was found to have a 4.4×3 cm tender, mobile mass on the left labium majus detached from the underlying perineal muscle. The patient underwent surgical excision under sedation and local anesthesia. The mass was easily removed intact and was not adherent to the vagina or the perineal muscles. Surgical resection of the lesion should be performed in order to remove the lesion and to confirm the diagnosis histologically. The diagnosis of long-standing endometriotic cyst was made. Primary vulvo-perineal endometriosis is a rare and difficult diagnosis especially in postmenopausal women without previous surgical procedures and no history of endometriosis. A better awareness of symptoms and signs of uncommon locations of extrapelvic endometriosis should be encouraged in order to optimize patient care. Finally, more research is needed to elucidate the pathogenesis of endometriosis in postmenopausal women.

Vaginal health and quality of sexual life of postmenopausal women on hyaluronic acid and Biosaccharide Gum-1 vaginal gel.

OBJECTIVE: To evaluate the efficacy of daily vaginal gel containing hyaluronic acid (HA) and Biosaccharide Gum-1 (BG-1) on vulvovaginal atrophy (VVA) and on sexual function and quality of life (QoL). MATERIALS AND METHODS: One hundred-four postmenopausal women with VVA were enrolled in the nonrandomized comparison cohort study. Of them, 50 women on HA/BG-1 participated in the study group and 54 women on lubricants/moisturizers on-demand as a control group. The primary endpoint was the efficacy of the vaginal gel on VVA evaluated by the Vaginal Health Index (VHI) score. Secondary endpoints included sexual behavior by the self-administered female sexual function index (FSFI) questionnaire, and quality of life (QoL), by the Short Form-36 questionnaire (SF-36). RESULTS: All symptoms of AVV improved after 12 weeks of treatment in women on HA/BG-1. The VMI, although improved at the 12-week follow-up compared to baseline, it connoted a low estrogenic stimulation value. Sexual function improved significantly in women on HA/BG-1. Moreover, women reported a significant improvement in the somatic aspects of QoL. No benefits were obtained by the women in the control group. CONCLUSIONS: Treatment with HA/BG-1 could have used in postmenopausal women who complain of vaginal dryness. The amelioration of VVA-related signs could improve sexual function and QoL.

How Does Contraceptive Use Affect Women's Sexuality? A Novel Look at Sexual Acceptability.

Among the components of a healthy life, sexuality is essential, contributing to both the psychophysical and social well-being of women and, consequently, to their quality of life. A poorly investigated standpoint is the acceptability of contraceptive methods, both in terms of their tolerability and metabolic neutrality and in terms of their impact on sexual life. In this context, we will provide an overview of the different methods of contraception and their effects on female sexuality, from biological changes to organic, social, and psychological factors, which can all shape sexuality. A MEDLINE/PubMed review of the literature between 2010 and 2021 was conducted using the following key words and phrases: hormonal contraception, contraceptives, female sexual function, libido, sexual arousal and desire, and sexual pain. Recent studies have supported the effects of contraceptives on women's sexuality, describing a variety of positive and negative events in several domains of sexual function (desire, arousal, orgasm, pain, enjoyment). However, satisfaction with sexual activity depends on factors that extend beyond sexual functioning alone. A more holistic approach is needed to better understand the multitude of factors linked to women's sexuality and contraception. Contraceptive counseling must consider these important elements since they are closely related to good compliance and maximize non-contraceptive health benefits.

Effects of hormone therapy containing 2 mg drospirenone and 1 mg 17ß-estradiol on postmenopausal exacerbation of Meniere's disease: Preliminary study.

The present study aimed to evaluate the effects of 2 mg drospirenone (DRSP) and 1 mg 17ß-estradiol (E2) hormone therapy (HT) in combination with rehabilitation therapy for postmenopausal women with Meniere's disease (MD). The combined drug hormone treatment was denoted as DRSP/E2. A total of 65 postmenopausal female patients with MD and severe distress were enrolled in the present prospective study. A total of 31 women comprised the study group (group A), undergoing HT and rehabilitation therapy, whereas 34 women who opted for rehabilitation therapy alone comprised the control group (group B). Vestibular function and distress associated with MD were assessed by stabilometry and the Dizziness Handicap Inventory (DHI) questionnaire, respectively. The data were collected at baseline and during the 3- and 6-month follow-up visits. The areas of the stabilometric ellipses exhibited a higher reduction in group A compared with group B with regard to the baseline values at both follow-up assessments (P<0.001). At baseline, both groups exhibited severe self-perceived discomfort, with similar DHI scores of 72.3±3.7 (group A) and 70.6±3.9 (group B; P=0.07). At the 3-month follow-up, both groups underwent a gradual improvement, which was significantly higher in group A (47.5±3.7) compared with in group B (64.2±3.3; P<0.001). At the 6-month follow-up, the DHI scores were improved in group A (43.4±3.4) compared with in group B (58.5±3.1; P<0.001). Therefore, DRSP/E2 HT was effective in reducing the fluid overload, which is characteristic of MD. The findings of the present study demonstrated that integrated therapy based on the administration of DRSP/E2 HT and rehabilitation may be more effective compared with rehabilitation alone for the management of postmenopausal exacerbation of MD.
