Sexual Dysfunction Is a More Common Problem in Young Women with Type 1 Diabetes than in Healthy Women

Diabetes mellitus and female sexual response: what do animal models tell us?

BACKGROUND

One of the less explored effects of diabetes mellitus (DM) is female sexual dysfunction. Females of different species have been used as models.

AIM

To analyze the information of animal models of DM and female sexual response (FSR).

METHODS

The literature of FSR in models of DM was reviewed.

OUTCOMES

Paradigm- and diabetes-dependent changes have been found in various aspects of the FSR.

RESULTS

Females in a type 1 DM (DM1) model show a decrease in the number of proestrus events, and ovariectomized females treated with sex hormones have been used. In these females, a reduction in lordosis has been reported; in proceptivity, the data are contradictory. These females present a decrease in sexual motivation that was restored after exogenous insulin. In the type 2 DM (DM2) model, females show regular estrous cycles, normal levels of lordosis behavior, and, depending on the paradigm, decreased proceptivity. These females display normal preference for sexually active males or their olfactory cues when having free physical contact; they lose this preference when tested in paradigms where physical interaction is precluded.

CLINICAL TRANSLATION

Preclinical data showing the high deleterious effects of a DM1 model and the less drastic effects under a DM2 model are in accordance with clinical data revealing a much higher prevalence of sexual dysfunction in women with DM1 than DM2.

STRENGTHS AND LIMITATIONS

The main strength is the analysis of the changes in various components of FSR in 2 models of DM. The main limitation is the difficulty in extrapolating the data on FSR from rats to women and that most studies focus on evaluating the impact of severe or chronic-moderate hyperglycemia/hyperinsulinemia on the sexual response, without considering other pathophysiologic alterations generated by DM.

CONCLUSION

Females with severe hyperglycemia have a decrease in FSR, while those with moderate hyperglycemia show much less drastic effects.

Prevalence and associated factors of sexual dysfunction in premenopausal women with type 1 diabetes: A systematic review and meta-analysis

BACKGROUND

Sexual dysfunction (SD) in women with diabetes is a multifaceted complication driven by hormonal, neuropathic and psychosocial factors. It has been reported that the prevalence of SD is higher in women with type 1 diabetes compared to both women with type 2 diabetes and women without diabetes. However, prevalence estimates of SD in women with type 1 diabetes are variable, due to the heterogeneity of the conducted studies and the various confounding factors that are associated with SD.

AIM

This review aimed to estimate the prevalence of SD in premenopausal women with type 1 diabetes compared to women without diabetes; consider current methods for measuring SD; and identify factors associated with SD in women with type 1 diabetes.

METHOD

A systematic review of the literature was conducted. Four electronic databases (Embase, MEDLINE, CINAHL, PsycINFO) were searched between 15 March and 29 April 2022, the search was updated on 4 February 2023 to identify studies that assessed SD in women with type 1 diabetes.

FINDINGS

The search yielded in 1104 articles; of these, 180 were assessed for eligibility. A meta-analysis of eight eligible studies revealed that the odds of experiencing SD is three times higher in women with type 1 diabetes compared to women without diabetes (OR = 3.8 95%CI 1.8-8.0, p < 0.001). The most commonly used measure of SD was the female sexual function index (FSFI); in three studies, this was combined with the female sexual distress scale (FSDS). Factors that have shown significant association with SD are depression, anxiety and duration of diabetes.

CONCLUSION

This review has shown that SD is a significant issue for women with type 1 diabetes. These findings should encourage diabetes professionals and policymakers to give more attention to female SD (FSD) by incorporating it into care pathways and clinical guidelines.

Prevalence and predictors of sexual dysfunction in females with type 1 diabetes: a systematic review and meta-analysis

BACKGROUND

Several observational studies have explored the prevalence and predictors of female sexual dysfunction (FSD) among females with type 1 diabetes. However, no systematic review and meta-analysis of pooled data provide reliable estimates of FSD prevalence among females with type 1 diabetes.

AIM

To investigate the global prevalence of FSD, analyze the association between FSD risk and type 1 diabetes, and evaluate the predictors of FSD among females with type 1 diabetes.

METHODS

The study search of the present systematic review was conducted through the Wanfang Database, China National Knowledge Infrastructure, PubMed, and Embase from the inception date to February 28, 2023. Heterogeneity among the studies was analyzed with the Q and I2 tests. The sources of heterogeneity were detected through subgroup analyses and meta-regression.

OUTCOMES

Outcomes included the pooled prevalence of FSD among females with type 1 diabetes, the association between FSD risk and type 1 diabetes, and the predictors of FSD among females with type 1 diabetes.

RESULTS

The pooled prevalence of FSD among females with type 1 diabetes was 38.5% (95% CI, 32.1%-45.0%). The risk of FSD was higher in patients with type 1 diabetes than in healthy controls (odds ratio [OR], 3.77; 95% CI, 2.24-6.35). The significant predictors of FSD among females with type 1 diabetes were depression status (OR, 2.77; 95% CI, 1.29-5.93) and longer diabetes duration (OR, 1.19; 95% CI, 1.06-1.34).

CLINICAL IMPLICATIONS

Females with type 1 diabetes had a significantly increased prevalence of FSD, indicating that clinicians should be concerned about FSD among females with type 1 diabetes.

STRENGTHS AND LIMITATIONS

The strength of the present study is that it is the first systematic review and meta-analysis to investigate the global prevalence and predictors of FSD among females with type 1 diabetes. The limitation is that the results revealed significant heterogeneity after pooling the articles.

CONCLUSIONS

The present systematic review and meta-analysis revealed that the overall prevalence of FSD among females with type 1 diabetes was 38.5%, demonstrating a significant association between FSD risk and type 1 diabetes among females. Furthermore, we found that the significant predictors for FSD among females with type 1 diabetes were depression and a longer duration of diabetes.

Physical Activity Protects Women with Type 1 Diabetes from Sexual Dysfunctions

The aim of the study was to evaluate the relationship between physical activity and sexual function in women with type 1 diabetes mellitus (T1DM). The study group consisted of 171 women with T1DM. All the participants voluntarily filled out anonymous questionnaires. Women who were sexually inactive or had some psychological, psychiatric, or endocrine diseases were excluded from the analysis. The scores about sexual function were obtained using a Female Sexual Function Index (FSFI) questionnaire. Results equal to or below 26 points indicate clinically significant sexual dysfunction. Physical activity was measured by the International Physical Activity Questionnaire (IPAQ). Participants were divided into two groups depending on the Metabolic Equivalent of Task (MET-min/week) score with a cutoff point 3000 MET-min/week. Results above 3000 points indicate higher physical activity in woman. There were statistically significant differences in lubrication, orgasm, pain, satisfaction, and total score of FSFI. A positive correlation was revealed between results in total FSFI score and MET-min/week score (Rs = 0.18, p = 0.016). Univariate logistic regression does not show significant associations, but the multivariate logistic regression model shows an association between the MET-min/week and the total FSFI score. The higher the MET-min/week score, the higher the FSI score, and thus better sexual function.

Comparison of sexual functions in women with and without type 1 diabetes

OBJECTIVE

This study aimed to investigate female sexual function in patients with type 1 diabetes by comparing female sexual function index scores between women with and without type 1 diabetes.

METHODS

A total of 62 women with type 1 diabetes and 69 age-matched women without diabetes but with similar backgrounds were enrolled in the patient and control groups, respectively. All participants were sexually active and had no systemic diseases other than diabetes in the patient group.

RESULTS

The frequency of female sexual dysfunction was significantly higher, and the mean female sexual function index score was significantly lower in women with diabetes compared to the control group (p=0.01). There was a significant relationship between sexual dysfunction and duration of diabetes, glycosylated hemoglobin test, and body mass index (p<0.05).

CONCLUSION

This study demonstrates that female sexual dysfunction is more common among women with type 1 diabetes than among women without type 1 diabetes. Patients with type 1 diabetes should be evaluated in terms of sexual health. Health professionals should give more attention to and provide guidance regarding sexual function in women with type 1 diabetes.

Sexual dysfunction in women with type 1 diabetes in Norway: A qualitative study of women's experiences

AIM

The aim of this study was to explore the experiences of sexual health and sexual challenges in women with type 1 diabetes (T1D).

METHODS

We used a qualitative study design and conducted semistructured interviews with 15 women (26-57 years) with T1D. The participants were recruited based on their Female Sexual Function Index score that indicated sexual dysfunction. We used thematic analysis to analyse the data.

RESULTS

We generated three themes, each with subthemes: (1) Diabetes is present at all times (subthemes: having diabetes is onerous, and diabetes affects the relationship with my partner); (2) various challenges related to sexual health (subthemes: experiencing reduced sexual desire and physical challenges, and challenges related to sexual health affect the relationship with my partner); and (3) diabetes may affect sexual function (subthemes: glucose levels and technical devices may have an impact on sexual function, and sexual health should be addressed in diabetes follow-up).

CONCLUSIONS

The women with T1D experienced different challenges related to their sexual health. The most common were reduced sexual desire, vaginal dryness and pain during intercourse. The study emphasizes the importance of addressing sexual health in diabetes follow-up to provide comprehensive health services to people with diabetes.

Sexual dysfunction in women with type 1 diabetes in Norway: A cross-sectional study on the prevalence and associations with physical and psychosocial complications

AIM

To estimate the prevalence of sexual dysfunction in women with type 1 diabetes (T1D) compared with women without diabetes and to analyse associations between sexual dysfunction and the presence of chronic physical diabetes complications, diabetes distress and depression in women with T1D.

METHODS

This cross-sectional study was conducted in Norway, and 171 women with T1D and 60 controls completed the Female Sexual Function Index (FSFI) and the Hospital Anxiety and Depression Scale (HADS). Diabetes distress was assessed with the Problem Areas in Diabetes (PAID) scale. Data on diabetes complications were retrieved from medical records. We performed logistic regression to estimate differences in the prevalence of sexual dysfunction (defined as FSFI ≤26.55) between women with T1D and women without diabetes and to examine associations of sexual dysfunction with chronic diabetes complications, diabetes distress and depression in women with T1D.

RESULTS

The prevalence of sexual dysfunction was higher in women with T1D (50.3%) compared with the controls (35.0%; unadjusted odds ratio [OR] 1.89 [95% confidence interval (CI) 1.06-3.37]; adjusted OR 1.93 [1.05-3.56]). In women with T1D, sexual dysfunction was associated with both diabetes distress (adjusted OR 1.03 [1.01-1.05]) and depression (adjusted OR 1.28 [1.12-1.46]), but there were no clear associations with chronic diabetes complications (adjusted OR 1.46 [0.67-3.19]).

CONCLUSIONS

This study suggests that sexual dysfunction is more prevalent in women with T1D compared with women without diabetes. The study findings emphasize the importance of including sexual health in relation to diabetes distress and psychological aspects in diabetes care and future research.

Reduced sexual motivation of diabetic female rats: Restoration with insulin

The aim of this study was to evaluate female rat sexual motivation in a model of diabetes mellitus type 1. Severe hyperglycemia was induced in ovariectomized Wistar rats by injecting streptozotocin [STZ, 100 mg/kg, i.p.]. Ten days later, females received estradiol benzoate (10 μg/rat, s.c.) plus progesterone (3 mg/rat, s.c.). A group of STZ-treated animals was administered with insulin (2-4 U) every 12 h for 10 days, which normalized glucose levels. In the partner preference (PP) and sexual incentive motivation (SIM) tests, control females spent more time close to a sexually experienced male (SE) than with a castrated male (CM). STZ-treated females stayed the same amount of time with both stimuli, that is, they lost their sexual preference. We also evaluated the sense of smell using two behavioral tests, one related to sexual odors (SO) and another one to food odors (FO). In the SO test, control females spent more time sniffing the sawdust coming from cages that contained SE males; hyperglycemic females remained the same amount of time sniffing the sawdust of both stimuli: SE and CM. In the FO test, no differences were found between control and STZ-treated groups. Insulin treatment reverted the changes observed in hyperglycemic females in the PP, SIM and SO tests. These data suggest that severe hyperglycemia decreases sexual motivation and that insulin recovers such diminution.

Sexual Function and Sexual Quality of Life in Premenopausal Women with Controlled Type 1 and 2 Diabetes-Preliminary Study

Sexual dysfunction is more common in women with diabetes than in women without diabetes. The aim of the study was to determine sexual function and the level of the quality of sex life in premenopausal women with controlled, uncomplicated type 1 and type 2 diabetes taking into account the stages of the menstrual cycle and mood level. The study included 163 women with type 1 and type 2 diabetes and 115 controls without diabetes. Questionnaire studies were conducted using the following surveys: Demographic and Clinical Data Survey, Female Sexual Function Index, Sexual Quality of Life—Female, and Beck Depression Inventory. Both phases of the menstrual cycle—follicular and luteal—were included. It was shown that, in women with type 1 diabetes, sexual function decreased during the luteal phase in comparison with the follicular phase (p < 0.001). In the women with type 2 diabetes and in the controls, sexual function was comparable during both phases of the cycle (p > 0.05). In the women with uncomplicated controlled type 1 diabetes, sexual function and the sexual and relationship satisfaction changed depending on the phase of the menstrual cycle with a decrease during the luteal phase. Sexual function and the quality of the sex life of premenopausal women with controlled type 2 diabetes were comparable during both the follicular and the luteal phases. Sexual function in menstruating women with controlled type 2 diabetes decreased with age and a worsening mood.
