ABSTRACT
Objective
This study aims to thoroughly investigate the effects of a daily dosage of 5mg tadalafil on key parameters such as ejaculation latency time, erectile function, and lower urinary tract symptoms (LUTS) in a cohort of men diagnosed with erectile dysfunction (ED). By documenting these effects, we hope to provide solid evidence for the pharmacological benefits of tadalafil in treating ED.
Materials and Methods
A total of 60 men, aged between 30 and 70 years, diagnosed with erectile dysfunction, participated in this comprehensive retrospective study. Each participant was required to complete validated questionnaires: the International Index of Erectile Function Questionnaire-5 (IIEF-5) to assess erectile function, the Intravaginal Ejaculatory Latency Time (IELT) assessment to evaluate ejaculation timing, and the International Prostate Symptom Score (IPSS) to categorize LUTS both before the commencement of treatment and at the conclusion of the 12-week treatment phase. During this period, participants received tadalafil 5mg orally once daily. The collected data underwent rigorous statistical analysis using independent-samples t-tests to ascertain significant variations pre- and post-treatment.
Results
The mean age of participants was noted to be 50.4 years. Initial assessment scores indicated an IELT of 2.2 minutes, an IIEF-5 score of 9.5, and an IPSS of 14.1. Upon completion of the treatment period, notable improvements were recorded: IELT significantly increased to 3.4 minutes, the IIEF-5 score reflected a rise to 16.1, and the IPSS diminished to an average of 10.4, all demonstrating statistical significance (p<0.01).
Conclusion
The findings of this study suggest that the daily administration of 5mg tadalafil is both a safe and effective treatment modality for enhancing erectile function and prolonging ejaculation latency time in men diagnosed with erectile dysfunction, thus potentially improving the overall quality of life in this demographic.

INTRODUCTION
Erectile dysfunction (ED) represents a common condition that affects millions of men globally, often leading to significant psychological distress and a marked decrease in life quality. Current estimations indicate that around 30 million men in the United States alone experience varying degrees of ED, attributable to a multitude of factors, including psychological issues, hormonal disturbances, and cardiovascular conditions.
Moreover, premature ejaculation (PE) frequently coexists with ED, as it is characterized by ejaculation occurring with minimal stimulation before or shortly after penetration. The interplay between PE and ED creates a complex clinical scenario, as each condition can exacerbate the other, thus necessitating effective treatment options.
Tadalafil, a well-known phosphodiesterase type 5 (PDE5) inhibitor, has gained prominence as a therapeutic agent in treating ED. The objective of this study is to delve deeper into the implications of daily administration of 5mg tadalafil on both IELT, erectile function, and associated LUTS in men afflicted with ED, thus enhancing our understanding of the compound’s clinical utility in managing sexual dysfunction.
MATERIALS AND METHODS
This study was conducted within a rigorously controlled clinical environment and received clearance from the local ethics committee. A cohort of 60 men, aged between 30 and 70, all diagnosed with erectile dysfunction, were recruited for participation. Each participant provided informed consent before enrollment in the trial.
Inclusion criteria mandated that participants were involved in stable heterosexual relationships for a minimum of six months. Those with neurological disorders, active urinary infections, or other contraindications to PDE5 inhibitors were excluded from the study.
Assessment Tools
The primary assessment measure was the IELT, which was recorded by the female partner utilizing a stopwatch during sexual intercourse. The IIEF-5 served to quantify erectile performance, while the IPSS was utilized to analyze LUTS severity. Each individual's baseline characteristics were meticulously noted prior to initiating the treatment and reassessed following three months of daily tadalafil administration.
RESULTS
The demographic analysis of participants indicated a mean age of 50.4 years, allowing for a statistical comparison of pre- and post-treatment results:
- IELT: Elevated from 2.2±1.4 to 3.4±1.9 minutes (p<0.01).
- IIEF-5: Increased from 9.5±3.7 to 16.1±4.7 (p<0.01).
- IPSS: Declined from 14.1±4.5 to 10.4±3.8 (p<0.01).
Adverse effects were minimal, with only 10% of participants reporting gastrointestinal disturbances and 8% experiencing headaches, indicating a favorable safety profile for tadalafil in this population.
DISCUSSION
The outcomes derived from this investigation are consistent with previous research that posits tadalafil as a significant modifier of both erectile function and ejaculation timing. The underlying physiological activities facilitating these enhancements likely stem from increased blood circulation and diminished sympathetic tone, ultimately fostering improved sexual performance.
Furthermore, the dual therapeutic benefit of tadalafil in addressing both ED and PE presents an integrative treatment option for men grappling with these conditions, which could help mitigate the associated psychological impacts and elevate overall sexual satisfaction.
For future research endeavors, it would be prudent to incorporate larger participant cohorts and extended follow-up durations to better elucidate the sustained benefits of long-term tadalafil usage across diverse demographics.
