Risk Factors Affecting Decreased Libido Among Middle-Aged to Elderly Men; Nocturnal Voiding is an Independent Risk Factor of Decreased Libido

Prevalence and predictors of unrecognised low sexual desire/interest in men with new onset erectile dysfunction: findings from a cross-sectional, real-life study

The interrelationship between male sexual desire and erectile dysfunction (ED) has been scantly investigated. Thus, we aimed at investigating the prevalence of and the predictors of unrecognised low sexual desire/interest (uLSD/I) in a cohort of men with new onset ED. Complete data from 1587 men seeking for first medical help for ED between 2010 and 2021 were analysed. Comorbidities were scored with the Charlson Comorbidity Index (CCI). At entrance, all patients were asked to self-report low sexual desire/interest and completed the International Index of Erectile Function (IIEF) and the Beck Depression Inventory (BDI) (depressive symptoms scored as BDI ≥ 11). The IIEF-erectile function (IIEF-EF) domain was categorised according to Cappelleri's criteria. The median value of the IIEF-sexual desire domain (IIEF-SD) was used to dichotomise men with uLSD/I along with ED (IIEF-SD < 7) vs. ED-only (IIEF-SD ≥ 7). Circulating hormones were measured in every patient. Hypogonadism was defined as total testosterone (tT) <3.0 ng/mL. Descriptive statistics and logistic regression models tested the association between clinical variables and uLSD/I. Of 1197 patients not self-reporting LSD/I, 369 (30.8%) had IIEF-SD < 7. Patients with ED + uLSD/I were older [median (IQR) 54(41-63) vs. 49(36-59) years], had lower IIEF-EF [10.5(5-22) vs. 22(11-28)] but higher BDI [6(3-12) vs. 4(1-8)] and lower tT [4.3(3.2-5.7) vs. 4.8(3.2-6.3) ng/mL] compared to ED-only men (all p < 0.05). Overall, ED + uLSD/I men had higher rate of severe ED (49.9% vs. 23.9%), and of BDI ≥ 11 (30.6% vs. 18.2%) (all p < 0.05). At multivariable logistic regression analysis, lower tT (OR: 0.82), lower IIEF-EF scores (OR:0.95) and BDI ≥ 11 (OR:2.51) were independently associated with ED + uLSD/I, after accounting for age (all p < 0.05). Almost 30% of men seeking first medical help for ED-only had also uLSD/I. Men with both conditions were older, had higher rates of severe ED and more depressive symptoms. A detailed investigation of sexual desire should be always included in men self-complaining only of ED.

Symptomatic dermographism in Chinese population: an epidemiological study of hospital-based multicenter questionnaire survey

OBJECTIVE

There are few epidemiological studies on SD in China. This study aims to clarify the epidemic distribution characteristics of SD in China and provide ideas and clues for the prevention and treatment of the disease.

METHODS

The cross-sectional study was conducted in 2019 based on the hospital's epidemiological questionnaire. All enrolled patients completed a specific survey with 39 questions, related to demographic characteristics and the relative symptoms. Demographics, disease symptoms were characterized with descriptive statistics. The differences in the symptoms between different genders, disease courses, and regions were compared.

RESULTS

A total of 1800 patients were recruited, of which 615 patients were diagnosed with SD. Among 615 SD patients, the proportion of patients with chronic spontaneous urticaria was the highest, with 437 cases (71.1%). There is a female predominance (female/male ratio is 1.27:1), but there is no statistically significant difference between genders. The average disease course was 2.23 years. Among them, 429 patients had a course less than one year, accounting for about 2/3, and patients with a course more than one year accounted for less than 1/3. The clinical characteristics of patients with different course of disease were statistically different. The initial age is mainly concentrated in the 20-40 years old, accounting for 46.5% (286) of the total number. There are certain differences in incidence due to the different geographical conditions in north and south. Multiple types of urticaria may coexist in the same patient, and the number of patients with multiple urticaria is higher than the number of patients with simple SD. There are differences in the clinical manifestations of SD between north and south.

CONCLUSIONS

Environmental factors may affect the occurrence of SD, which may have a similar etiology to other types of urticaria and the cause of SD can be explored from more perspectives.
