Female sexual dysfunction after bariatric surgery in women with obesity: A systematic review and meta-analysis

Effects of bariatric surgery on sexual function and fertility: A narrative review

Obesity has emerged as a prevalent global health concern, with its detrimental effects on the reproductive system and sexual function garnering increasing attention. Both men and women affected by obesity face a heightened risk of fertility challenges and sexual dysfunction. Although fertility and sexual function are distinct topics, they are intricately linked and mutually influential in both medical and societal contexts. Bariatric surgery (BS) has generated promising results in alleviating sexual dysfunction and enhancing fertility, results which are often gender specific. In men, improvements in sexual function can often be attributed to weight loss and subsequent optimizations in sex hormone levels. However, improving female sexual function may be related to a range of factors beyond weight loss. Bariatric procedures have shown limited benefits for male fertility; in fact, in some situations it can even be detrimental, leading to a decrease in sperm count and quality. Conversely, BS may positively impact female fertility, improving pregnancy and neonatal outcomes. Nevertheless, it is essential to consider the potential risks related to the adverse effects of malnutrition and rapid weight loss following BS, making it advisable to wait for 12-18 months before attempting pregnancy.

Psychological symptoms and brain activity alterations in women with PCOS and their relation to the reduced quality of life: a narrative review

BACKGROUND

Polycystic ovary syndrome (PCOS) is the most common feminine endocrine disorder, characterized by androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. The negative impact of symptoms on the quality of life (QoL) of patients is still not clear.

PURPOSE

The present review aimed at studying the impact of the symptoms, the psychological symptoms, and brain alterations in women with PCOS.

METHODS

A systematic search was undertaken for studies that assessed the impact of PCOS symptoms on QoL, psychological symptoms, and brain alterations in PCOS patients.

RESULTS

Most of the information about QoL came from psychometric studies, which used culture-based questionnaires. Alterations of sleep quality, body image, and mood disorders can negatively affect the QoL of the patients. Sexual satisfaction and desire were affected by PCOS. Brain imaging studies showed functional alterations that are associated with impairments of visuospatial working memory, episodic and verbal memory, attention, and executive function.

CONCLUSIONS

Several factors can negatively influence the quality of life of the patients, and they are directly related to hyperandrogenism and the risk of infertility. In particular, obesity, hirsutism, acne, and the fear of infertility can have a direct impact on self-esteem and sexual function. Metabolic and psychiatric comorbidities, such as mood, anxiety, and eating disorders, can affect the well-being of the patients. Moreover, specific cognitive alterations, such as impairments in attention and memory, can limit PCOS patients in a series of aspects of daily life.

Sexual function in women with polycystic ovary syndrome: a systematic review and meta-analysis

BACKGROUND

Polycystic ovary syndrome (PCOS) is a common and distressing endocrine disorder associated with lower quality of life, subfertility, diabetes, cardiovascular disease, depression, anxiety, and eating disorders. PCOS characteristics, its comorbidities, and its treatment can potentially influence sexual function. However, studies on sexual function in women with PCOS are limited and contradictory.

OBJECTIVE AND RATIONALE

The aim was to perform a systematic review of the published literature on sexual function in women with PCOS and assess the quality of the research and certainty of outcomes, to inform the 2023 International Guidelines for the Assessment and Management of PCOS.

SEARCH METHODS

Eight electronic databases were searched until 1 June 2023. Studies reporting on sexual function using validated sexuality questionnaires or visual analogue scales (VAS) in PCOS populations were included. Random-effects models were used for meta-analysis comparing PCOS and non-PCOS groups with Hedges' g as the standardized mean difference. Study quality and certainty of outcomes were assessed by risk of bias assessments and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) method according to Cochrane. Funnel plots were visually inspected for publication bias.

OUTCOMES

There were 32 articles included, of which 28 used validated questionnaires and four used VAS. Pooled Female Sexual Function Index (FSFI) scores in random-effects models showed worse sexual function across most subdomains in women with PCOS, including arousal (Hedges's g [Hg] [95% CI] = -0.35 [-0.53, -0.17], I2 = 82%, P < 0.001), lubrication (Hg [95% CI] = -0.54 [-0.79, -0.30], I2 = 90%, P < 0.001), orgasm (Hg [95% CI] = -0.37 [-0.56, -0.19], I2 = 83%, P < 0.001), and pain (Hg [95% CI] = -0.36 [-0.59, -0.13] I2 = 90%, P < 0.001), as well as total sexual function (Hg [95% CI] = -0.75 [-1.37, -0.12], I2 = 98%, P  =  0.02) and sexual satisfaction (Hg [95% CI] = -0.31 [-0.45, -0.18], I2 = 68%, P < 0.001). Sensitivity and subgroup analyses based on fertility status and body mass index (BMI) did not alter the direction or significance of the results. Meta-analysis on the VAS studies demonstrated the negative impact of excess body hair on sexuality, lower sexual attractiveness, and lower sexual satisfaction in women with PCOS compared to controls, with no differences in the perceived importance of a satisfying sex life. No studies assessed sexual distress. GRADE assessments showed low certainty across all outcomes.

WIDER IMPLICATIONS

Psychosexual function appears to be impaired in those with PCOS, but there is a lack of evidence on the related distress scores, which are required to meet the criteria for psychosexual dysfunction. Health care professionals should discuss sexual function and distress and be aware of the multifactorial influences on sexual function in PCOS. Future research needs to assess both psychosexual function and distress to aid in understanding the degree of psychosexual dysfunction in PCOS. Finally, more diverse populations (e.g. non-heterosexual and more ethnically diverse groups) should be included in future studies and the efficacy of treatments for sexual dysfunction should also be assessed (e.g. lifestyle and pharmacological interventions).

Obesity management: sex-specific considerations

Obesity is a global health issue that has grown to epidemic proportions. According to World Health Organisation (WHO), overweight and obesity are responsible for more than 1.2 million deaths in Europe each year, representing > 13% of the region's total mortality. Highly processed, calorie-dense foods and reduced physical activity are considered as primary drivers of obesity, but genetic predisposition also plays a significant role. Notably, obesity is more prevalent in women than in men in most countries, and several obesity-related comorbidities exhibit sex-specific pathways. Treatment indication depends on BMI (body mass index), as well as existing comorbidities and risk factors. To reduce obesity-associated comorbidities, a permanent reduction in body weight of (at least) 5-10% is recommended. Treatment guidelines suggest an escalating stepwise approach including lifestyle intervention, pharmacotherapy, and bariatric-metabolic surgery. As cumulative evidence suggests differences in weight loss outcomes, there is growing interest in sex-specific considerations in obesity management. However, most trials do not report weight loss or changes in body composition separately for women and men. Here, we discuss state-of-the-art obesity management and focus on current data about the impact of sex on weight loss outcomes.

Obesity and sexual health: focus on postmenopausal women

Menopause is a cardiometabolic transition with many women experiencing weight gain and redistribution of body fat. Hormonal changes may affect also several dimensions of well-being, including sexual function, with a high rate of female sexual dysfunction (FSD), which displays a multifactorial etiology. The most important biological factors range from chronic low-grade inflammation, associated with hypertrophic adipocytes that may translate into endothelial dysfunction and compromised blood flow through the genitourinary system, to insulin resistance and other neuroendocrine mechanisms targeting the sexual response. Psychosocial factors include poor body image, mood disorders, low self-esteem and life satisfaction, as well as partner's health and quality of relationship, and social stigma. Even unhealthy lifestyle, chronic conditions and putative weight-promoting medications may play a role. The aim of the present narrative review is to update and summarize the state of the art on the link between obesity and FSD in postmenopausal women, pointing to the paucity of high-quality studies and the need for further research with validated end points to assess both biomarkers of obesity and FSD. In addition, we provide general information on the diagnosis and treatment of FSD at menopause with a focus on dietary interventions, physical activity, anti-obesity drugs and bariatric surgery.

Association between obesity and female sexual dysfunction: a review

INTRODUCTION

Obesity is a global health crisis that has been growing over the past few decades. The economic burden associated with obesity is substantial as it is associated with multiple disabling chronic diseases, such as cardiovascular disease, certain cancers, osteoarthritis, chronic pain, and mental illness. Obesity is known to be a risk factor for sexual dysfunction in men, but this association is less well understood in women.

AIMS

To provide a narrative review of the available literature on the relationship between overweight/obesity and female sexual dysfunction, elaborate on the possible mechanisms explaining this association, and discuss the effects of weight loss on sexual function in those with obesity.

METHODS

A search of the medical literature was carried out in PubMed and Medline, focusing on original research and systematic reviews of original research on obesity and sexual function in women.

RESULTS

The relationship between obesity and female sexual function is not consistent across studies. While women with obesity are more likely to have worse sexual function and avoid sexual activity, many studies have failed to identify these associations. Lifestyle changes resulting in weight loss lead to better sexual function, and bariatric surgery has been shown to improve sexual function in the first couple of years following the procedure; yet, the long-term effects of weight loss and bariatric surgery are still uncertain.

CONCLUSIONS

The evidence on the relationship between obesity and female sexual function is mixed. Nevertheless, weight loss has been shown to improve sexual function in women with obesity. The impact of weight loss medications and the long-term effect of bariatric surgery on female sexual function require further study.

Sexuality and self-concept of morbidly obese women who are sexually attracted to men after bariatric surgery: a phenomenological study

BACKGROUND

Morbid Obesity (MO) is a public health problem that affects a person's physical, psychological and sexual well-being. Women with MO are affected by their body image and self-concept, and obesity stigma may affect women in social and sexual relationships.

OBJECTIVE

To describe and understand the experiences of morbidly obese heterosexual women (who are sexually attracted to men) in relation to their body image and sexuality after bariatric surgery.

METHODOLOGY

Qualitative study using Merleau-Ponty's hermeneutic phenomenology as a philosophical framework. Data collection took place between 2020 and 2021 in a southern Spanish province. A total of 22 in-depth interviews were conducted using open-ended questions until data saturation was reached.

RESULTS

Two main themes were identified: (1) "Escaping from a cruel environment": weight loss to increase self-esteem; with the sub-themes: 'I love myself now', and 'Body image and social relationships; a vicious circle; (2) "Now, I am truly me": accepting my body to reclaim my sexuality, with the sub-themes: 'The body as the focal point of sexuality', and 'When regaining your sex drive reignites your sex life and relationship'.

CONCLUSION

Weight loss and body acceptance radically change morbidly obese women's sex lives after bariatric surgery. They rediscover their bodies, have increased self-esteem, and see improvements in their social relationships and sexuality. These women feel seen, loved and desired, and now value their body image and femininity. As they go through continuous improvements following bariatric surgery, they gradually regain self-esteem, acceptance of their bodies and control over their sex life. Even though the women's partners benefit from these improvements, they seem to be afraid of being left.

Embracing the Pros and Cons of the New Weight Loss Medications (Semaglutide, Tirzepatide, Etc.)

PURPOSE OF REVIEW

The history of multiple weight loss medications has been a concerning paradox based on an increased cardiovascular risk despite significant reductions in adipose tissue and weight. A new class of weight loss medications could change this past narrative based on early preliminary results of cardiovascular risk (not events-still need to be determined) and weight reduction in non-diabetics that acutely competes with results achieved with bariatric surgery. The purpose of this review is to provide a comprehensive summary of the advantages and disadvantages of these newer medications, and how they could impact urology.

RECENT FINDINGS

Weight loss of - 15 to - 20% compared to baseline has become plausible in the short-term and preliminary guidance to reduce acute and chronic adverse events are receiving attention. However, the cost, access, conflicts of interest, supply chain, life-long adherence issues, and the long-term diverse implications on mental and physical health when exposed to this class of medications (GLP-1 agonists) are unknown. The profound caloric reductions should also result in baseline or ongoing nutritional deficiency testing, and general and specific dietary recommendations, which could theoretically mimic some bariatric surgery pre- and post-surgical protocols but has yet to be studied. Regardless, the potential impact of these medicines within a variety of medical specialties needs clinical research. Current and future lifestyle interventions, dietary patterns, and medicines in the weight loss category need to be held to a paradigm whereby cardiovascular health should improve with significant weight loss without a negative impact on mental health. In urology, the ability to impact cancer risk, ED, FSD, incontinence, infertility, nephrolithiasis, and multiple other endpoints are plausible (based on bariatric surgery data) but need preliminary clinical research. Other medicines with a similar or even larger potential impact are in clinical trials, and thus, a concise overview for clinicians and researchers was needed for objective guidance. Currently, comprehensive lifestyle changes utilized with and without these medications continue to garner positive mental, physical, and legacy effects, which suggest that they are as necessary as ever in the treatment of the numerous conditions impacted by unhealthy weight gain.

Effect of Surgically Induced Weight Loss on Pelvic Organ Prolapse: A Meta-analysis

INTRODUCTION

Bariatric surgery alleviates certain aspects of pelvic floor disorder, but the effect on pelvic organ prolapse (POP) is unclear. To assess the effect of bariatric surgery on POP we conducted the present meta-analysis and firstly performed a subgroup analysis based on the duration of follow-up.

METHODS

Four databases including PubMed, The Cochrane Library, Web of Science, and Embase were searched to identify relevant studies published before February 24, 2023. The main outcome was the prevalence and severity of POP symptoms before and after bariatric surgery. Then we assessed the heterogeneity, publication bias and performed subgroup analyses based on follow-up time, study quality and region.

RESULTS

Eleven studies with a total of 696 participants met the inclusion criteria. The results showed that the prevalence of POP decreased after bariatric surgery (odds ratio[OR] = 2.29, 95% confidence interval[CI]: 1.05, 5.01; P = 0.04, I2 = 78%), with significant differences observed both at 3-6 months (OR = 2.24, 95% CI: 1.25, 4.01; P = 0.007, I2 = 59%) and 12 months (OR = 4.64, 95% CI: 2.83, 7.58; P < 0.0001, I2 = 0%) of follow-up compared with pre-surgery. Pelvic Organ Prolapse Distress Inventory scores 6-item also decreased after bariatric surgery (mean difference [MD] = 2.11, 95% CI: 0.32, 3.89; P = 0.02, I2 = 55%) with significant differences observed both at 3-6 months (MD = 3.72; 95% CI: [0.10, 7.34], P = 0.04, I2 = 70%) and ≥ 12 months (MD = 3.24; 95% CI: [0.56, 5.91], P = 0.02, I2 = 56%) of follow-up.

CONCLUSION

Bariatric surgery alleviated POP symptoms in women with obesity both during short-term (3-6 months) and long-term (≥ 12 months) follow-up.

Sexual Function and Satisfaction in the Context of Obesity

PURPOSE OF REVIEW

Sexual dysfunction is commonly associated with overweight/obesity, but the underlying physiological and psychosocial mechanisms are not fully understood. This review contextualizes the obesity-sexual (dys)function relationship, describes recent insights from the medical and social science literature, and suggests opportunities for continued research.

RECENT FINDINGS

Although sexual dysfunction has been historically evaluated as a consequence/outcome of obesity, it is increasingly considered as a harbinger of future metabolic comorbidities, including type 2 diabetes and cardiovascular disease. Body image dissatisfaction is a consistent predictor for lower sexual satisfaction across BMI categories, likely mediated by cognitive distraction during partnered sex. To fully capture the relationship between obesity and sexual dysfunction, multidisciplinary research approaches are warranted. While clinically significant weight loss tends to improve sexual functioning for women and men, higher body image satisfaction may independently promote sexual function and satisfaction without concomitant weight loss.

The global prevalence of sexual dysfunction in obese and overweight women: a systematic review and meta-analysis

BACKGROUND

Obesity is a pressing public health risk issue worldwide. Women, in particular, face a higher risk of obesity. Recent research has highlighted the association between obesity and female sexual dysfunction. Therefore, the objective of this study is to investigate the global prevalence of sexual dysfunction in obese and overweight women through a systematic review and meta-analysis.

METHODS

In this study, a systematic search was conducted across electronic databases, including PubMed, Scopus, Web of Science, Embase, ScienceDirect, and Google Scholar. The search aimed to identify studies published between December 2000 and August 2022 that reported metabolic syndrome's impact on female sexual dysfunction.

RESULTS

The review included nine studies with a sample size of 1508 obese women. The I2 heterogeneity index indicated high heterogeneity (I2: 97.5). As a result, the random effects method was used to analyze the data. Based on this meta-analysis, the prevalence of sexual dysfunction in women with obesity was reported as 49.7% (95%CI: 35.8-63.5). Furthermore, the review comprised five studies involving 1411 overweight women. The I2 heterogeneity test demonstrated high heterogeneity (I2: 96.6). Consequently, the random effects model was used to analyze the results. According to the meta-analysis, the prevalence of sexual dysfunction in overweight women was 26.9% (95% CI: 13.5-46.5).

CONCLUSION

Based on the results of this study, it has been reported that being overweight and particularly obese is an important factor affecting women's sexual dysfunction. Therefore, health policymakers must acknowledge the significance of this issue in order to raise awareness in society about its detrimental effect on the female population.

The Paradox of Sexual Dysfunction Observed during Pregnancy

The aim of this study is to analyze the evolution of sexual function throughout pregnancy and highlight the predicting factors of sexual dysfunction in pregnant women. Our study included 144 participants, aged 16 to 45. Patients were evaluated three times during pregnancy by filling out the Female Sexual Function Index (FSFI) and the Body Exposure in Sexual Activities Questionnaire (BESAQ). At the time of the last evaluation, we asked patients to also fill out Beck's Depression Inventory (BDI-II) and a questionnaire regarding their psychological status and relationship satisfaction. We observed that the FSFI lubrication, satisfaction, and pain domains and the FSFI total score significantly decreased from the 1st to the 3rd evaluation. We observed that an increase in BDI score and the presence of abortion in the patient's history increase the risk of developing female sexual dysfunction (FSD). Higher BMIs were found to be a protective factor against FSD, as was being unmarried. The relationship satisfaction score was found to be an independent predictor of FSD. These findings support previous studies that indicate that pregnancy and postpartum sexuality are multifaceted phenomena and that psycho-social factors have a greater impact on sexuality than biological factors.

Benefits and Risks of Bariatric Surgery on Women's Reproductive Health: a Narrative Review

Bariatric surgery (BS) is escalating as the most efficient and endurable therapy for severe obesity. Women's reproductive health is essential to women's quality of life and is receiving increasing attention. However, despite the high prevalence of BS among women, the effect of BS on reproductive health remains underemphasis. The purpose of this narrative review is to provide an overview of BS on women's reproductive health, including their reproductive health before, during, and after pregnancy. Although limited attention has been given, current evidence highlights the substantial implications of bariatric surgery on reproductive health and reminds us of the importance of adopting decision-making conversations about reproductive health before bariatric surgery.
