Effects of hyperthyroidism, hypothyroidism, and thyroid autoimmunity on female sexual function

Thyroid diseases and female sexual dysfunctions

INTRODUCTION

Female sexual dysfunctions (FSDs) have received little attention in the context of thyroid diseases, despite the high prevalence of both conditions.

OBJECTIVES

This review aims to update and summarize the state of knowledge on the association between thyroid diseases and FSDs and to investigate the complex mechanisms through which thyroid hormone imbalance can impact female sexual health in the context of the biopsychosocial model.

METHODS

A comprehensive literature search was performed through the PubMed, MEDLINE, and Scopus databases, using the following keywords: "female sexual function," "sexual dysfunction," "hypoactive sexual desire disorder," "thyroid disease," "thyroiditis," "hypothyroidism," and "hyperthyroidism."

RESULTS

To date, well-designed studies that describe the relationship between FSDs and thyroid disorders are lacking. However, despite the limitations on available studies, current data indicate that sexual alterations are frequently associated with thyroid diseases in women. A complex interplay of direct and indirect hormonal and nonhormonal mechanisms has been hypothesized, including hormonal changes, neurotransmitter imbalance, reduced nitric oxide release, mood disorders, and other systemic consequences of both hypothyroidism and hyperthyroidism. Thyroid hormone receptors have also been identified in the genitourinary system.

CONCLUSIONS

In a clinical setting, physicians should investigate the sexuality of patients consulting for thyroid disease. At the same time, an evaluation of thyroid function should be performed in patients presenting with FSD, especially after menopause, when the risk of thyroid diseases and FSDs increases strongly.

The impact of hyperthyroidism on sexual functions in men and women: a systematic review and meta-analysis

This study aimed to review the current knowledge on sexual dysfunction in men and women with hyperthyroidism through a systematic review and meta-analysis. Available clinical trials from the MEDLINE database were searched using a prerecorded protocol (Protocol Prospero ID: CRD42022340587), and obtained data were analyzed and reported according to the PRISMA guidelines. Pooled effect estimates were computed using a random-effects model. Twenty eligible studies were identified, of which 15 were included in this meta-analysis. The prevalence of erectile dysfunction was significantly higher in participants with hyperthyroidism than that in controls [odds ratio = 9.16 (95% confidence interval [CI], 5.0-16.5)]. Treatment of hyperthyroidism alone improved erectile functions [effect size, ES = 0.36 (95% CI, -0.01-72)] and mean intra-vaginal ejaculation latency time [ES = 0.63 (95% CI, 0.27-98)] among men with erectile dysfunction and/or premature ejaculation. The prevalence of premature ejaculation also decreased with treatment of hyperthyroidism [odds ratio = 0.11 (95% CI, 0.04-28). Women with hyperthyroidism demonstrated higher odds in female sexual dysfunction than controls [odds ratio = 4.34 (95% CI, 2.63-7.18)]. Female sexual function index scores in women with hyperthyroidism were also significantly lower than those in the controls with moderate effect sizes. An evident and reversible disruption of sexual functions under hyperthyroidism conditions was observed in both sexes.

Sexual Function and Depressive Symptoms in Young Women with Euthyroid Hashimoto's Thyroiditis Receiving Vitamin D, Selenomethionine and Myo-Inositol: A Pilot Study

Thyroid autoimmunity is associated with an increased risk of sexual dysfunction. The aim of this study was to compare sexual functioning and depressive symptoms in women with Hashimoto's thyroiditis receiving different treatments. The study included euthyroid women with autoimmune thyroiditis, untreated or receiving vitamin D, selenomethionine, or myo-inositol. Apart from measuring antibody titers and hormone levels, all participants completed questionnaires evaluating female sexual function (FSFI) and depressive symptoms (BDI-II). In untreated women, the overall FSFI scores and domain scores for desire, arousal, lubrication, and sexual satisfaction were lower than in women receiving vitamin D, selenomethionine, and myo-inositol. In the vitamin D-treated women, the total FSFI scores and scores for desire and arousal were higher than in women receiving the remaining micronutrients. The BDI-II score was lowest in the vitamin D-treated women and highest in the untreated patients with thyroiditis. Vitamin D-treated women were also characterized by lower antibody titers and higher testosterone levels than the women receiving the remaining micronutrients. There were no differences in sexual functioning and depressive symptoms between the selenomethionine- and myo-inositol-treated women. The study results suggest that although all antibody-lowering treatments are associated with better sexual functioning and well-being in young women with euthyroid autoimmune thyroiditis, the greatest benefits are observed in patients receiving vitamin D.

Vaginal estrogen and association with dementia: A nationwide population-based study

INTRODUCTION

Use of systemic hormone therapy has been positively associated with development of dementia. Little is known about the dose-dependent effect of vaginal estradiol on dementia risk.

METHODS

We assessed associations between cumulative dose of vaginal estradiol tablets and dementia in a case-control study nested in a nationwide Danish cohort of women aged 50 to 60 years at study initiation, who did not use systemic hormone therapy. Each case was age-matched to 10 female controls.

RESULTS

A total of 4574 dementia cases were matched to 45,740 controls. Cumulative use of vaginal estradiol tablets was not associated with all-cause dementia; adjusted hazard ratio 1.02 (95% confidence interval [CI] 0.89-1.18) for low dose (< 750 mcg), 1.07 (0.94-1.21) for medium dose (750-2000 mcg), and 0.93 (0.84-1.03) for high dose (> 2000 mcg). Similarly, Alzheimer's disease (AD) only was not associated with vaginal estradiol.

DISCUSSION

Exposure to vaginal estradiol tablets was not associated with all-cause dementia or AD only.

Is There an Association Between Hypothyroidism and Sexual Dysfunction: A Systematic Review and Cumulative Analysis

INTRODUCTION

Many investigators have found a detrimental effect on sexual functioning developed by hypothyroidism in both sexes, but a cumulative analysis has not been conducted.

AIM

This study aims to summarize and quantify the association between overt or subclinical hypothyroidism and the risk of sexual dysfunction (SD) through a meta-analysis.

METHODS

4 electronic databases were systematically searched. The quality of evidence was rated by the GRADE approach. This meta-analysis was registered on the PROSPERO (ID: CRD42020186967).

MAIN OUTCOME MEASURE

The strength of the relationship between overt/subclinical hypothyroidism and SD was quantified by presenting the relative risk (RR) with its 95% confidence interval (CI).

RESULTS

7 studies involving 460 patients with hypothyroidism and 2,143 healthy controls were included in this meta-analysis. Among the 7 included studies, 2 studies were provided the data of both overt and subclinical hypothyroidism. Pooled results from 4 included studies investigating overt hypothyroidism indicated that overt hypothyroidism led to significant SD in both sexes (RR = 2.26, 95% CI: 1.42 to 3.62, P = 0.001), while synthetic RR of 5 eligible studies reporting subclinical hypothyroidism failed to find a positive association between subclinical hypothyroidism and SD (RR = 1.3, 95% CI: 0.85 to 1.99, P = 0.229), irrespective of gender (all P > 0.05). Subgroup analyses revealed that women with overt hypothyroidism rather than men with overt hypothyroidism were correlated with a significant higher risk of SD. The quality of evidence in the study of overt hypothyroidism and subclinical hypothyroidism was considered low and moderate, respectively.

CONCLUSION

SD is a devastating problem in female patients with clinical hypothyroidism but insusceptible in either women or men with subclinical hypothyroidism. Clinicians should be aware of these phenomena and manage the sufferers accordingly in clinical practice. More rigorous studies are still needed to validate this evidence. Shen M, Li X, Wu W, et al.

Thermal Ablation for Papillary Thyroid Microcarcinoma: How Far We Have Come?

Purpose

Thermal ablation (TA), as one of the most currently remarkable technologies, has achieved great success in many malignant diseases including but not limited to hepatic and renal carcinoma. In recent years, this technology was gradually introduced to the treatment of papillary thyroid microcarcinoma (PTMC) and even papillary thyroid carcinoma (PTC). Thereby, we summarized the current progress of TA development in the treatment of PTMC.

Methods

The latest relevant literature from the PubMed database with keywords "thermal ablation", "papillary thyroid microcarcinoma", "microwave ablation", "radio-frequency ablation", and "laser ablation", among others, were comprehensively reviewed in this article. The follow-up outcomes of patients in these articles were analyzed.

Results

The efficacy and safety of TA including microwave ablation (MWA), laser ablation (LA), and radiofrequency ablation (RFA) in the treatment of PTC and PTC have been intensively studied. Based on existing clinical trials, the relatively long-term follow-up (range, from 6 to 64.2 months) results in MWA, LA, and RFA were satisfactory that tumor volume reduction rate (VRR) reached and even surpass 99%. Compared with routine surgery methods (total thyroidectomy and lobectomy), the incidence rate of complications was relatively lower and the recurrence rate of TA techniques was not statistically significant, whereas the operative time, blood loss, length of hospital stay, and hospital cost were significantly decreased.

Conclusion

TA presents the same satisfactory therapeutic effects but minimal postoperative trauma can significantly improve the patients' quality of life. However, future larger sample, multicenter, and prospective randomized controlled trials are urgently needed to validate the feasibility of TA in dealing with PTMC.

Association Between Overt Hyperthyroidism and Risk of Sexual Dysfunction in Both Sexes: A Systematic Review and Meta-Analysis

BACKGROUND

Numerous studies have shown the detrimental effects of overt hyperthyroidism on sexual functioning but a quantitative result has not yet been synthesized.

AIM

To conduct a systematic review and meta-analysis that quantifies the association between overt hyperthyroidism and the risk of sexual dysfunction (SD).

METHODS

A meta-analysis of studies in the literature published prior to February 1, 2020, from 4 electronic databases (MEDLINE, Embase, Cochrane Library databases, and PsychINFO) was conducted. All analyses were performed using the random-effects model comparing individuals with and without overt hyperthyroidism.

OUTCOMES

The strength of the association between overt hyperthyroidism and risk of SD was quantified by calculating the relative risk (RR) and the standard mean difierences with 95% CI. The quality of evidence for the reported outcome was based on the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Of 571 publications, a total of 7 studies involving 323,257 individuals were included. Synthetic results from 7 eligible studies indicated that overt hyperthyroidism led to significant SD in both sexes (pooled RR = 2.59, 95% CI: 1.3-5.17, P = .007; heterogeneity: I² = 98.8%, P < .001). When we analyzed the data of men and women independently, the pooled results consistently showed that men and women with overt hyperthyroidism were at over 2-fold higher risk of SD than the general populations (RR for males = 2.59, 95% CI: 1.03-6.52, P = .044; RR for females = 2.51, 95% CI: 1.47-4.28, P = .001). Combined standard mean diffierences from those studies providing the Female Sexual Function Index (FSFI) suggested that women with overt hyperthyroidism were associated with a significantly lower FSFI value in FSFI total scores, subscale sexual arousal, lubrication, orgasm, and satisfaction domain (all P < .05). The overall quality of evidence in our study was considered to be moderate.

CLINICAL IMPLICATIONS

Clinicians should know the detrimental effects of overt hyperthyroidism on sexual functioning in clinical practice. Measurement of thyroid hormones should be included in the assessment of patients presenting with SD when they show symptoms of clinical hyperthyroidism.

STRENGTHS & LIMITATIONS

This is the first meta-analysis quantifying the relationship between overt hyperthyroidism and the risks of SD. However, the combined results were derived from limited retrospective studies along with substantial heterogeneities.

CONCLUSION

Our study has confirmed the potentially devastating sexual health consequences caused by overt hyperthyroidism. However, additional rigorous studies with sizable samples are still needed to better elucidate this evidence. Pan Y, Xie Q, Zhang Z, et al.

Sexual Function in Levothyroxine-Treated Hypothyroid Women and Women without Hypothyroidism: A Case-Control

Background: Levothyroxine is the most common treatment to normalize thyroid hormones levels and to reduce primary hypothyroidism symptoms. Aim: To assess sexual function in women with levothyroxine-treated hypothyroidism and women without hypothyroidism. Methods: A case-control study was performed with 152 women with levothyroxine-treated hypothyroidism and 238 women without hypothyroidism. An online survey was used to collect socio-demographic data and the answers to the Women Sexual Function (WSF) questionnaire. Results: Women with levothyroxine-treated hypothyroidism showed a higher prevalence of sexual dysfunction than women in the control group (31.60% vs. 16.40%), furthermore the presence of hypothyroidism increased the risk of sexual dysfunction (p = 0.002, OR: 2.29 (1.36−3.88)). The most affected domains were ‘desire’ (p < 0.001), ‘arousal’ (p = 0.003) and ‘penetration pain’ (p = 0.020). In hypothyroid women, age increased the risk of sexual dysfunctions (p = 0.009, OR: 1.07 (1.01−1.12)), however when age was adjusted (ANCOVA) the sexual dysfunction remained in women with hypothyroidism in all domains. Conclusions: Hypothyroidism is associated with an increase in the prevalence of sexual dysfunction even if treated with levothyroxine and thyroid-stimulating hormone (TSH) levels are normalized. Relevance to clinical practice: Sexual function in hypothyroid women should be assessed before and after starting the treatment.

Effects of Hypothyroidism and Subclinical Hypothyroidism on Sexual Function: A Meta-Analysis of Studies Using the Female Sexual Function Index

Introduction

Hypothyroidism and subclinical hypothyroidism (SCH) are common metabolic diseases with severe psychological and physiological effects, which may be the risk factors of sexual dysfunction.

Aim

The purpose of this study is to explore the influence of hypothyroidism and SCH on female sexual function through systematic literature review.

Methods

Until February 2020, systematic searches were conducted on Pubmed, Web of Science, EMBASE, and Clinicalkey to obtain eligible studies to report the mean and standard deviation of Female Sexual Function Index (FSFI) in various fields in women with clinical hypothyroidism, SCH, and healthy controls. In accordance with the results of heterogeneity test, a random effect model or fixed effect model was selected to aggregate the scores of each field. The scores of female patients with hypothyroidism and healthy controls were compared using forest plot. Stata (version 15.1) uses meta-analysis.

Main Outcome Measure

Evaluation values of various fields of FSFI in clinical hypothyroidism, SCH, and healthy controls.

Results

This study included 7 studies, including 88 women with clinical hypothyroidism, 337 women with SCH, and 2056 healthy controls. Compared with healthy controls, patients with hypothyroidism scored lower in all FSFI dimensions (desire, arousal, lubrication, orgasm, satisfaction, and pain), especially in lubrication. And, only arousal and orgasm decreased in patients with SCH. Hypothyroidism (odds ratio = 3.912, P = .002) rather than SCH (odds ratio = 1.036, P = .886) was a risk factor for female sexual dysfunction.

Conclusion

Hypothyroidism does impair female sexual function to varying degrees. SCH has little effect on female sexual function. It is essential to measure and evaluate the thyroid function of women with sexual dysfunction regularly, which can help clinicians improve sexual function and sexual quality of life.

Sexual function and depressive symptoms in young women with overt hyperthyroidism

OBJECTIVE

Despite high prevalence in a female population, surprisingly little is known about sexual functioning of women with thyroid hyperfunction. This study was aimed at assessing female sexual function and depressive symptoms in women with overt hyperthyroidism of autoimmune and non-autoimmune origin.

STUDY DESIGN

The study included three age-matched groups of young women inhabiting the Upper Silesia (a selenium-deficient and iodine-sufficient area): individuals with overt hyperthyroidism induced by Graves' disease (group A, n = 31), women with overt hyperthyroidism caused by toxic multinodular goiter or toxic adenoma (group B, n = 30) and women with normal thyroid function (group C, n = 34). Apart from measuring serum hormone levels, serum antibody titers and determining calculated parameters of thyroid homeostasis, all women completed questionnaires evaluating femalesexual function (FSFI) and depressive symptoms (BDI-II).

RESULTS

The mean total FSFI score and all domain scores were lower while the overall BDI-II score was higher in both groups of women with overt hyperthyroidism than in the control group, and correlated with thyrotropin and free thyroid hormone levels, as well as with the SPINA-GT index. The FSFI score as well as domain scores for desire, arousal and sexual satisfaction were lower, while the BDI-II score was higher in group A than in group B. In group A, the total FSFI score, desire, arousal, sexual satisfaction and severity of depressive symptoms correlated with TRAb and TPOAb titers.

CONCLUSION

The obtained results suggest that excessive thyroid hormone production and thyroid autoimmunity have an additive effect on sexual functioning and mood.

Effect of Thyroid Hormone Derangements on Sexual Function in Men and Women

INTRODUCTION

Sexual dysfunction affects many people, with 33‒60% of women reporting sexual dysfunction and 8‒52% of men with erectile dysfunction or premature ejaculation. In an effort to determine the constellation of factors responsible for sexual dysfunction, the effect of thyroid hormone derangements has been of recent interest.

AIM

To investigate the associations between thyroid hormones and sexual dysfunction in women and men.

METHODS

Literature was reviewed to examine the effects of hypo- and hyperthyroidism on sexual function.

MAIN OUTCOME MEASURE

We present a summary of the effects of thyroid dysfunction on domains of sexual functioning.

RESULTS

Most studies demonstrate that men with hypo- and hyperthyroidism have increased rates of sexual dysfunction, including erectile dysfunction in men with hypothyroidism. However, studies vary on the strength of correlation between hormonal derangement and level of sexual dysfunction. In both men with hyper- and hypothyroidism, treating the thyroid disorder at least partially reverses sexual dysfunction. In contrast, the current literature provides no consensus on the effect of hypothyroidism, hyperthyroidism, or Hashimoto's thyroiditis on female sexual function. In studies that observed increased rates of sexual dysfunction in women with thyroid disorders, correction of the thyroid derangement resulted in resolution of some sexual dysfunction. Studies are also conflicted on whether there is a relationship between the degree of sexual dysfunction and the degree of hormone derangement in women. However, prior work has demonstrated a relationship between thyroid autoantibodies and sexual dysfunction in women.

CONCLUSION

Thyroid dysfunction is an important factor in the pathogenesis of sexual dysfunction in men and possibly women. Evidence suggests a reversibility of sexual dysfunction with correction of thyroid dysfunction, although the exact pathophysiology of thyroid-mediated sexual dysfunction remains unknown. However, current evidence supports thyroid derangements rather than autoantibodies as the causative factor in men, whereas autoantibodies appear to play a more prominent role in women.

Patients with Benign Thyroid Diseases Experience an Impaired Sex Life

BACKGROUND

This study aimed to characterize the frequency of self-reported thyroid-related impaired sex life in patients with thyroid diseases, to examine its clinical correlates and relationship with overall quality of life (QOL), and to investigate the effect of treatment.

PATIENTS AND METHODS

Two separate patient samples with benign thyroid diseases were investigated: a cross-sectional sample (759 women and 118 men) treated at two Danish university hospital outpatient clinics, in 2007-2008, and a longitudinal sample (358 women and 74 men) undergoing treatment at the abovementioned centers, during 2008-2012, evaluated before and 6 months after therapy. The thyroid-specific QOL questionnaire ThyPRO was used to measure patient-evaluated thyroid-related sex life impairment. Biochemical and clinical variables were analyzed (i.e., age, education, degree of thyroid dysfunction, comorbidity, serum thyrotropin, total thyroxine, and triiodothyronine, as well as thyroperoxidase and thyrotropin receptor antibody concentrations). The SF-36 Health Survey was used to analyze the effect of impaired sex life on overall QOL.

RESULTS

In the cross-sectional sample, 36% of women and 31% of men reported what they perceived to be thyroid-attributable impaired sex life. Women with autoimmune thyroid diseases reported more impairment than those with non-autoimmune thyroid diseases. In patients with Graves' disease lower levels of educational attainment and in patients with toxic nodular goiter comorbidities were associated with impaired sex life. Overall QOL was lower in patients with thyroid-related sex life impairment. In the longitudinal sample, 42% of women and 33% of men had impaired sex life at baseline, which improved at 6 months follow-up only in women and, when analyzing individual diagnoses separately, statistically significantly among those with autoimmune hypothyroidism. Sexual impairment was associated with low education in patients with toxic nodular goiter and with high plasma triiodothyronine concentrations in patients with Graves' disease. In autoimmune hypothyroidism, a younger age was associated with sex life impairment.

CONCLUSION

We found a high frequency of self-reported, thyroid-related sex life impairment in patients with benign thyroid diseases, especially in young women with autoimmune thyroid diseases. Self-perceived impaired sex life persisted in women treated for Graves' disease, suggesting that normalization of thyroid function was not sufficient to restore sexual function.

Sexual function and depressive symptoms in young women with hypothyroidism receiving levothyroxine/liothyronine combination therapy: a pilot study

Objective Even mild hypothyroidism in pre-menopausal women is accompanied by impaired sexual functioning. The study was aimed at comparing the effect of levothyroxine, administered alone or in combination with liothyronine, on sexual function and depressive symptoms in pre-menopausal women treated because of hypothyroidism. Methods This quasi-randomized, single-blind study included 39 young women receiving levothyroxine treatment who, despite thyrotropin and thyroid hormone levels within normal limits, still experienced clinical symptoms of hypothyroidism. These patients were divided into two groups: group A (n = 20) continued levothyroxine treatment, while group B (n = 19) received levothyroxine/liothyronine combination therapy. At the beginning of the study, and 6 months later, all participants of the study filled in questionnaires evaluating female sexual functioning (Female Sexual Function Index; FSFI) and the presence and severity of depressive symptoms (Beck Depression Inventory-Second Edition; BDI-II). Results The study was completed by 37 women. Baseline sexual functioning and depressive symptoms did not differ between the study groups. Neither the total FSFI score nor the domain scores changed throughout the study in women who continued levothyroxine treatment. Compared to levothyroxine administered alone, levothyroxine/liothyronine combination therapy increased scores for two domains: sexual desire and arousal, tended to increase the total FSFI score, as well as tended to decrease the overall BDI-II score. The effect of the combination therapy on sexual function correlated with a treatment-induced increase in serum levels of free triiodothyronine and testosterone. Conclusions The obtained results suggest that levothyroxine administered together with liothyronine is superior to levothyroxine administered alone in affecting female sexual functioning.

Elevated free triiodothyronine may lead to female sexual dysfunction in Chinese urban women: A hospital-based survey

Research on female sexual dysfunction (FSD) is limited, especially in China, due to conservative culture and beliefs. There has been a dearth of FSD screening research in China since the optimal cutoff value of the Chinese version of the Female Sexual Function Index (CVFSFI) was determined in 2014. At the same time, the relationship between thyroid hormones and FSD has seldom been explored in Chinese women. Therefore, hospital-based research was conducted to elucidate FSD frequency and risk factors. Women who underwent a check-up at the Health Promotion Center were approached to participate and, if consented, were enrolled in the study. Demographic and socioeconomic data was extracted. All participants completed the CVFSFI and Beck Depression Inventory (BDI) self-report questionnaires and underwent thyroid hormone tests. A total of 1119 participants were included in the final analysis, with a mean age of 38.6 ± 7.6 years and average CVFSFI score of 25.7 ± 3.9. The frequency of FSD among the participants in this hospital-based cross-sectional study was 26.5%. In addition to age, menopause, parity and depression status as risk factor, and annual income (40,000–100,000 RMB/year) and educational background (≥university) as protective factor, elevated free triiodothyronine (fT3) was identified as an independent risk factor of FSD.

Sexual function and depressive symptoms in young women with thyroid autoimmunity and subclinical hypothyroidism

OBJECTIVE

The results of few studies conducted to date suggest an increased prevalence of sexual dysfunction in patients with thyroid disorders.

DESIGN

The aim of this study was to compare female sexual function and depressive symptoms between women with autoimmune thyroid disease and with mild thyroid failure.

PATIENTS

The study included four groups of young women: euthyroid women with Hashimoto's thyroiditis (Group 1), women with nonautoimmune subclinical hypothyroidism (Group 2), women with autoimmune subclinical hypothyroidism (Group 3) and healthy euthyroid females without thyroid autoimmunity (Group 4).

MEASUREMENTS

Beyond measuring serum hormone levels and thyroid antibody titres, all enrolled women completed questionnaires evaluating female sexual function (Female Sexual Function Index - FSFI) and the presence and severity of depressive symptoms (Beck Depression Inventory-Second Edition - BDI-II).

RESULTS

The mean total FSFI score was lower in women with autoimmune hypothyroidism than in the remaining groups of women, as well as lower in Groups 1 and 2 than in Group 4. Compared to Group 4, three domains (sexual desire, lubrication and sexual satisfaction) were lower in Group 1, four domains (desire, arousal, lubrication and dyspareunia) in Group 2 and all FSFI domain scores in Group 3. The total BDI-II score was higher in Groups 1 and 2 than in Group 4, as well as higher in Group 3 than in the other groups of women.

CONCLUSIONS

The obtained results suggest that both thyroid autoimmunity and mild thyroid failure, particularly if they occur together, may negatively affect female sexual function and depressive symptoms.

Female sexual dysfunction in women with thyroid disorders

BACKGROUND

Few data exist on the prevalence of female sexual dysfunction (FSD) in thyroid disorders.

AIM

We evaluated FSD in women with thyroid diseases and in control age-matched healthy women to investigate the relationship between sexual function and thyroid hormones.

METHODS

One hundred and four women with thyroid diseases and 53 controls participated in the study. Eighteen with hyperthyroidism (Group 1), 22 hypothyroidism (Group 2), 45 Hashimoto's thyroiditis (Group 3), 19 nodular goiter (Group 4) underwent thyroid function evaluation and sonography. The Female Sexual Function Index (FSFI) assessed sexual function.

RESULTS

The prevalence of FSD was 46.1% in thyroid diseases and 20.7% in controls. Only in Group 4, the prevalence (68.4%) was significantly higher than in controls (p<0.005). The mean total FSFI score was 20.1 ± 7.1 in women with thyroid diseases and 25.6 ± 4.7 in the controls (p<0.001). Compared with controls, there was a significant decrease of desire in Group 2; desire, arousal and lubrication in Group 3; desire, arousal, lubrication, orgasm and satisfaction in Group 4. In thyroid diseases the prevalence of FSD was 53% and 42%, while in the controls was 55% and 20%, in menopausal and pre-menopausal groups, respectively. We found a significant inverse correlation between TSH and FSFI (r=-0.7, p=0.01) in Group 4, which showed the lowest FSFI score (17.8 ± 5.7) and the highest body mass index (28.4 ± 7.1 kg/m(2)).

CONCLUSIONS

Women with thyroid diseases present a higher prevalence of FSD than controls. Although our findings suggest a higher impairment of sexual function in Group 4 and a role for TSH in FSD, further researches are needed.
