Introduction
Prior research conducted on treatment of erectile dysfunction (ED) has been derived from surveys involving relatively small populations of men. There are needs for large population-based studies in this area. Our study addresses that need.
Aim
The aim of this study was to characterize ED treatment among a large population of men.
Methods
Patients ≥30 years in commercial insurance dataset with diagnosis code for ED during 12-month period ending June 2011 were identified. Men were considered “treated” if prescription was filled for phosphodiesterase type 5 inhibitor (PDE5i), injection or urethral prostaglandins, or androgen replacement (ART) during study period. “Untreated” patients received the diagnosis but did not fill prescription. Statistical analyses were used to compare prescription frequency with clinical characteristics, including age and comorbidities.
Main Outcome Measures
ED treatment rates among large population of insured men, treatment types employed, patient demographics, associated medical comorbidities of this population, and prescriber details were the main outcome measures.
Results
Only 25.4% of 6,228,509 men with ED were treated during study period. While PDE5is were the most commonly prescribed medical therapy (75.2%), ART was utilized as monotherapy or in combination therapy in 30.6% of men. ART was significantly (P < 0.0001) more frequently used in men <40 and >65 years. Although ED frequency was associated with increased age and number of comorbidities, men >60 years were significantly (P < 0.0001) less likely to be treated compared with men aged 40–59 years. Additionally, treatment frequency did not vary as a function of number of comorbidities. However, compared with men with prostate cancer, men with comorbid hypogonadism, sleep disorders, benign prostatic hyperplasia, or components of metabolic syndrome were (P < 0.0001) more likely to be treated.
Conclusions
Despite high prevalence of ED with age and comorbidities, most men continue receiving no treatment. Although benefits of medical intervention for ED are well-recognized, many barriers to treatment continually exist including physician, patient and partner preference and knowledge.
BackgroundTimed and frequent intercourse around the time of female ovulation is recommended to improve conception. Although a significant number of articles have examined how the length of abstinence affects these semen analysis, the effects of frequent (daily) ejaculation has not been rigorously studied.MethodsTwenty normal men were recruited for daily ejaculation over 14 consecutive days, after a 3–5 days abstinence period. Semen samples were collected at the beginning of the study (day 1) and then on days 3, 7 and 14. In addition to the standard semen analysis, markers of sperm DNA quality were assessed.ResultsThe mean age of men completing the study was 25 years (range, 23–33 years). Significant decreases were observed in mean semen volume, total motile count (TMC) and sperm concentration during the study period without significant changes in motility or morphology. A large initial change in ejaculate volume, TMC and sperm concentration provided the primary difference in these values over the study period, with a plateau in values after this initial decrease (after study day 3). Metrics of DNA integrity did not change in a statistically or clinically meaningful way during the study period.ConclusionsWhile a small study, this represents the most extensive examination of sperm quality with daily ejaculation. These findings generally support an approach of a short period of abstinence followed by daily copulation around ovulation to maximize the number of sperm available and optimize conception.
Metanephric adenomas are a rare neoplasm of the kidney with less than 200 cases reported. We report a case of a metanephric adenoma incidentally found on imaging in a 52-year-old Hispanic female and treated with robot-assisted laparoscopic partial nephrectomy. A brief review of the literature is also included.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
