ABSTRACT
Objective
The purpose of this study is to systematically investigate the effects of administering a daily dose of 5mg tadalafil on ejaculatory timing, erectile function, and the presence of lower urinary tract symptoms (LUTS) in men diagnosed with erectile dysfunction. Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, has previously been shown to positively influence erectile function, but its role in ejaculatory timing and LUTS requires further exploration.
Materials and Methods
This study enrolled 60 men clinically diagnosed with erectile dysfunction. Participants were provided with 5mg tadalafil daily, adhering to a treatment plan that lasted three months. The effectiveness of the treatment was evaluated through several validated measures, including the International Index of Erectile Function questionnaire-5 (IIEF-5), which assesses erectile function; the intravaginal ejaculatory latency time (IELT), which measures ejaculatory timing; and the International Prostate Symptoms Scores (IPSS), which assesses urinary symptoms. Blood samples were collected to analyze levels of fasting glucose, testosterone, and lipid profiles, which could correlate with the outcomes measured. Statistical evaluations were conducted using independent-samples t-tests to compare the pre-treatment scores with post-treatment scores across the participant sample.
Results
The men participating in the study had a mean age of 50.4 years (±7.9). Initial assessments indicated an average IELT of 2.2 minutes, an IIEF-5 score of 9.5 suggesting moderate erectile dysfunction, and an IPSS score of 14.1 indicating a significant presence of urinary symptoms. Following the treatment, the IELT increased to an average of 3.4 minutes, while the IIEF-5 score improved to 16.1, and the IPSS score decreased to 10.4, with all changes demonstrating statistical significance (p < 0.01). These results confirm a marked enhancement in both ejaculatory timing and erectile function post-treatment, highlighting the effectiveness of tadalafil in this patient population.
Conclusion
The findings of this study provide compelling evidence that daily administration of 5mg tadalafil significantly enhances both ejaculatory latency and erectile functioning in men diagnosed with erectile dysfunction. These results advocate for the inclusion of tadalafil in clinical practices aimed at treating these overlapping sexual health concerns, supporting its dual efficacy as an effective therapeutic option.

INTRODUCTION
Erectile dysfunction (ED) is a widespread health issue affecting a significant number of men globally, often coexisting with premature ejaculation (PE). Epidemiological studies suggest that about 30% of men experiencing ED also report concomitant challenges with premature ejaculation. This investigation seeks to examine the application of 5mg tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, in improving sexual function, particularly in men presenting with both erectile dysfunction and premature ejaculation.
The ramifications of ED extend beyond the physical, substantially affecting a man's quality of life, instigating psychological issues such as anxiety and diminished self-esteem. Tadalafil has garnered attention as a favored treatment modality for erectile dysfunction owing to its favorable pharmacokinetic profile and prolonged duration of action. Accumulating literature proposes that tadalafil could also prolong ejaculatory latency, positioning it as a multifaceted treatment option for sexual dysfunction.
MATERIALS AND METHODS
The participant cohort was recruited from a urology outpatient clinic from January 2015 to January 2016. Inclusion criteria mandated a formal diagnosis of erectile dysfunction in accordance with the International Classification of Diseases guidelines. Exclusion parameters encompassed patients engaged in concurrent treatments for sexual dysfunction, as well as those with significant comorbidities that could interfere with the study outcomes.
Following approval from the local ethics committee, informed consent was obtained from all participants. Comprehensive baseline evaluations incorporated detailed medical histories, physical examinations, and laboratory tests to measure testosterone and other pertinent biomarkers. Blood samples were drawn after a 12-hour fasting period to determine glucose and lipid profiles.
During the intervention period, subjects were administered 5mg of tadalafil daily for three months. The effectiveness of this pharmacological intervention was gauged through the IIEF-5 questionnaire and IELT assessments, collaboratively recorded by the participants' partners during sexual encounters.
Statistical Analysis
For statistical analysis, SPSS software was utilized to perform comparative evaluations of pre- and post-treatment metrics. Changes were scrutinized using paired t-tests and Wilcoxon signed-rank tests where pertinent. A p-value of less than 0.05 was designated as statistically significant, underscoring the robustness of the results.
RESULTS
The study enrolled 60 participants reporting a mean age of 50.4 years. Post-treatment evaluations revealed statistically significant enhancements in IELT (p < 0.001), IIEF-5 scores (p < 0.001), and IPSS (p < 0.001). Participants reported mild and transient side effects, predominantly headaches and gastrointestinal issues, which were self-resolving.
Table Summary:
| Measure | Pre-treatment | Post-treatment |
|---|---|---|
| IELT (minutes) | 2.2 ± 1.4 | 3.4 ± 1.9 |
| IIEF-5 | 9.5 ± 3.7 | 16.1 ± 4.7 |
| IPSS | 14.1 ± 4.5 | 10.4 ± 3.8 |
DISCUSSION
This study validates the clinical utility of 5mg tadalafil not only for addressing erectile dysfunction but also for enhancing ejaculatory control. These findings are congruent with prior research illustrating a positive association between PDE5 inhibitors and overall sexual satisfaction. The physiological mechanism underpinning these improvements relates to enhanced blood flow, which is likely to facilitate both erectile function and ejaculatory latency.
Future longitudinal studies are essential to substantiate these findings and broaden the understanding of tadalafil's long-term benefits on sexual health across diverse populations. A deeper investigation into the potential mechanisms by which tadalafil influences ejaculatory timing and sexual satisfaction will also be crucial in establishing a comprehensive treatment paradigm for affected individuals.
CONCLUSION
A daily dose of 5mg tadalafil emerges as an effective therapeutic option for men experiencing erectile dysfunction, demonstrating significant improvements in both erectile capability and ejaculatory latency. These results advocate for the incorporation of tadalafil into treatment protocols tailored for patients grappling with the dual challenges of erectile dysfunction and premature ejaculation.
