“…Dietary supplements for sexual enhancement were most used among males aged 20–29 years, with a decreasing trend according to age advancement, even though the prevalence of erectile dysfunction (ED) increasing in correlation to age has been previously reported [22,23,24]. The proportion of moderate-to-severe ED among men who lived with their spouses varied from 1.8% in the age group of 20–29 years to 64.3% in those over 70 years [22].…”

Are There Adverse Events after the Use of Sexual Enhancement Nutrition Supplements? A Nationwide Online Survey from Japan

et al. 2019

Dozens of safety alerts for sexual enhancement and weight loss dietary supplements have been launched from the government not only in Japan but also overseas. However, adverse events have been reported only for the use of weight loss supplements, and the prevalence of use and adverse events in sexual enhancement supplements is not known in Japan. To address this issue, we assessed the situation of sexual enhancement supplement use through a nationwide online survey. The prevalence of sexual enhancement supplement use among males was 23.0%. Use of these supplements was higher among younger people than among older people (p < 0.001). In total, 17.6% of users had experienced adverse events, but 58.3% of them did not consult about the events with anybody because of the temporality of their symptoms and their sense of shame. In addition, eight supplement products were found to be possible adulterated supplements in this survey. It is necessary to inform the public about the risk of sexual enhancement supplement use and also prepare a place for consultation on media channels that younger people are more familiar with, in order to monitor adverse events while also preserving their privacy.

“…The clinical approach to SED is still to be defined, as only few studies have evaluated non-ED conditions. A recent 15-year observational study conducted in Japanese men showed an association between penile rigidity decrement in each decade of life (40 s, 50 s, 60 s, and 70 s) and dissatisfaction with their own sexual function (except from men 70 years and above); this association was shown whether or not patients met the criteria for classical ED [26]. An objective quantification of penile rigidity (thus to find even slight differences in rigidity among the spectrum of non-ED patients) could be obtained through imaging techniques, such as virtual touch tissue quantification (VTTQ).…”

Purpose: The aim of this study was to compare the initial request for sexual consultation with the final diagnosis and to evaluate the limits of the active andrological anamnesis concerning unclassified male sexual dysfunction. Methods: In this 12-year observational retrospective study, we collected data from patients referring to an andrological outpatient clinic, evaluating the requests, perceptions, needs, and self-diagnosis at their first visit and comparing them with the final diagnosis reached after a complete clinical, laboratory, and instrumental investigation. Results: A total of 11,200 patients were evaluated. The main request of andrological consultation was erectile dysfunction (ED) (52%), followed by premature ejaculation (PE) (28%), and low sexual desire (11.5%). Among the patients seeking help for ED, about 30% were ultimately found to have a different type of dysfunction and 24% were diagnosed with an “unmet need”, which included issues not present in the current nosography nonetheless affecting sexual and relational life. Among the patients referring for PE, the final diagnosis was lifelong PE for the large majority of them, regardless of whether initially they thought to have an acquired form. Several of those who sought consultation for acquired PE were frequently found to be able to compensate for lifelong PE by a subsequent coitus or were able to induce orgasm in the partner with different modalities. Among the patients referring for low sexual desire, only 57.5% were confirmed to have it; 23% had ED and 18.5% showed a raised threshold of penile sensitivity. Conclusions: The results of this study show that the reason for consultation is frequently misleading and raise the relevance of being aware of the so-called “unmet needs” and to discuss with the patient and the couple to explore the sexual history behind the self-diagnosis. These findings also suggest the need to expand the current taxonomy of male sexual dysfunctions.

“…Among them, 398 patients who originally had impaired preoperative sexual function (IIEF-5 score, <12 points) and 38 patients who did not answer the questionnaire 12 months after surgery were excluded. Erectile dysfunction severity is typically classified into 5 categories based on IIEF-5 scores: severe (5-7), moderate (8)(9)(10)(11), mild-to-moderate (12)(13)(14)(15)(16), mild (17)(18)(19)(20)(21), and no ED (22)(23)(24)(25). The average IIEF-5 score for a 50-year-old Japanese man has been reported as 16 points.…”

Background We investigated potential disparities in health-related quality of life, particularly concerning urinary function, between patients with preserved and those with impaired sexual function after robot-assisted radical prostatectomy (RARP). Materials and methods Between December 2012 and April 2020, 704 men underwent RARP in our hospital. This study included 155 patients with a preoperative 5-item International Index of Erectile Function (IIEF-5) of ≥12 points and an assessable IIEF-5 at 12 months postoperatively. Health-related quality of life was assessed using the 8-item Short-Form Health Survey and Expanded Prostate Cancer Index Composite (EPIC) preoperatively and at 3, 6, and 12 months postoperatively. A logistic regression analysis and Wilcoxon rank sum tests were performed. Results Patients were grouped according to the median IIEF-5 score 12 months after surgery: those with preserved sexual function (n = 71) and those with impaired sexual function (n = 84). The mental component summary of the 8-item Short-Form Health Survey was better in the group with preserved sexual function at 6 months postoperatively than in the group with impaired sexual function (p < 0.01). In the EPIC, the group with preserved sexual function performed better not only in the sexual domain but also in the urinary domain at all time points compared with the group with impaired sexual function (p < 0.01). In the comparison of the urinary subdomains of the EPIC, there were no significant differences in urinary function or incontinence, but there were significant differences in urinary distress and irritative/obstructive scores (p < 0.01). Conclusions Patients with preserved postoperative sexual function after RARP showed better urinary function than those with impaired sexual function. Hence, preserved sexual function is closely associated with urinary function.
