Sexual Dysfunction in Chronically Medicated Male Inpatients With Schizophrenia: Prevalence, Risk Factors, Clinical Manifestations, and Response to Sexual Arousal

Predictors of sexual activity and function in women and men with multiple sclerosis - a preliminary study

Introduction

The aim of the study was to determine predictors of sexual activity and function in patients with multiple sclerosis (MS).

Material and methods

A total of 134 MS patients were included in the study. Sexual activity and function were assessed by the Changes in Sexual Functioning Questionnaire (CSFQ). Symptoms of sexual dysfunction related to multiple sclerosis (the Multiple Sclerosis Intimacy and Sexuality Questionnaire-19; MSISQ-19), disability status in multiple sclerosis (the Expanded Disability Status Scale; EDSS), gender and age were also taken into account.

Results

This analysis indicated that all predictors (gender, age, EDSS score, and all three MSISQ-19 subscales) were significantly associated with the explained variable (sexual activity and function) in the expected direction. Finally, hierarchical regression showed that significant predictors of sexual activity and function were: (a) male gender, (b) age (negative relationship), and (c) primary sexual dysfunction symptoms (negative relationship).

Conclusions

Sexual activity and function can be predicted by using the MSISQ-19, which makes it a useful tool for communication between clinicians and patients.

The effect of calcium oxalate stones and uric acid stones on male sexual function

PURPOSE

This study compared the effects of calcium oxalate stones and uric acid stones on male sexual function.

METHODS

We enrolled 100 patients with ureteral stones. According to the composition of the stones, they were divided into the calcium oxalate stone group and the uric acid stone group. All patients underwent ureteroscopic holmium laser lithotripsy. General data such as age, body mass index, course of disease, stone diameter, and degree of renal hydronephrosis were compared. Sperm parameters, including sperm density, sperm viability, and sperm deformity rate, as well as International Index of Erectile Function-5 questionnaire (IIEF-5) scores, and Quality of Life (QOL) scores, were measured and compared before and 6 weeks after the surgery.

RESULTS

There were no statistically significant differences in general data and sperm parameters between the two groups before the surgery (P > 0.05). However, there were significantly lower IIEF scores but significantly higher QOL scores in the uric acid stone group. In the calcium oxalate stone group, there were no statistically significant differences in sperm parameters, IIEF score, and QOL score before and after the surgery (P > 0.05). In the uric acid stone group, there were no statistically significant differences in sperm parameters before and after surgery (P > 0.05), whereas there were significantly higher IIEF scores but significantly lower QOL scores after the surgery (P < 0.05). The prevalence of erectile dysfunction (ED) in the uric acid stone group was 38.18% (21/55), which was significantly higher compared to 20.00% (9/45) in the calcium oxalate stone group (P < 0.05). The multivariate binary logistic regression analysis showed that the independent risk factor related to ED was uric acid stones (odds ratio: 2.637, 95% confidence interval 1.040-6.689, P = 0.041). No statistically significant differences were found in sperm parameters between patients with and without ED.

CONCLUSION

Compared with the calcium oxalate stone group, patients with uric acid stones had a higher prevalence of ED and poorer sexual performance.

Prevalence of sexual dysfunction in Chinese patients with schizophrenia: a systematic review and meta-analysis

Background

There may be a higher risk of sexual dysfunction in the schizophrenia population. China has made significant contributions to the global community of patients with schizophrenia. Currently, there is no estimation of the prevalence of sexual dysfunction in Chinese patients with schizophrenia.

Aim

We conducted a meta-analysis to pool the evaluated prevalence of sexual dysfunction in Chinese patients with schizophrenia.

Methods

We systematically searched PubMed, Web of Science, Embase, PsycINFO, China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang Medical Network, and Huayi Academic Literature Database from inception to September 2023. Meta-analysis was conducted with R version 4.3.1.

Outcomes

To examine the pooled prevalence of sexual dysfunctions among Chinese patients with schizophrenia.

Results

In our meta-analysis, we included 16 studies with 5417 participants, among whom 1727 experienced sexual dysfunction. The results of the meta-analysis reveal that the prevalence of sexual dysfunction in Chinese patients with schizophrenia is 50.43% (95% CI, 37.86%-62.95%). Subgroup analysis results indicate that various factors-including the specific type of dysfunction, duration of illness, assessment tools, mean ages, study region, gender, research setting, marital status, publication years, and type of antipsychotics-all have a particular impact on the occurrence rate of sexual dysfunction in Chinese patients with schizophrenia. Female patients had a slightly higher prevalence of sexual dysfunction than male patients (65.22% vs 54.84%).

Clinical Implications

The findings of this study can be used in high-quality nursing care for the schizophrenia population, particularly for the care of specific sexual dysfunction nursing.

Strengths and Limitations

This meta-analysis is the first to evaluate the prevalence of sexual dysfunction in China among patients with schizophrenia. The limited number of studies is the most important limitation.

Conclusions

The pooled prevalence of sexual dysfunction in Chinese patients with schizophrenia is relatively high, and the prevention and intervention of individual sexual dysfunctions in schizophrenia are advised.
