Fact check: What is the average ejaculation time for men in their 20s versus 50s?

1. Summary of the results

Based on the available research, there is clear evidence that ejaculation time decreases with age. The most comprehensive data comes from a multinational population survey which found that the median intravaginal ejaculation latency time (IELT) was 6.5 minutes for men aged 18-30 years compared to 4.3 minutes for men older than 51 years ^[1]. This represents a significant decrease of approximately 2.2 minutes between younger and older age groups.

A Korean study examining ejaculatory control found that men in their 20s scored 6.3 ± 2.3 points for control over ejaculation, while men in their 50s or older scored 5.6 ± 2.5 points, indicating decreased control with advancing age ^[2]. Additionally, research suggests that more men are classified as having premature ejaculation in the 60-79 years age group compared to the 40-59 years age group, further supporting the age-related decline in ejaculatory function ^[3].

2. Missing context/alternative viewpoints

The original question lacks important contextual information about what constitutes "normal" ejaculation time. A Japanese study found that the estimated mean intromission time was 14.5 minutes for males, which is significantly longer than the ejaculation latency times reported in other studies ^[4]. This discrepancy highlights the difference between total intercourse duration and actual ejaculation latency time.

The research also reveals that premature ejaculation is a complex condition with multiple contributing factors beyond age. Several sources discuss comprehensive management approaches and diagnostic criteria ^{[5] [6] [7]}, suggesting that age is just one factor among many that influence ejaculatory function. The pathophysiology involves neurobiological, psychological, and relationship factors that may vary significantly between individuals regardless of age.

3. Potential misinformation/bias in the original statement

The original question assumes that there are established "average" ejaculation times for specific age groups, but the research shows considerable individual variation within age groups. The question also fails to distinguish between different types of ejaculatory measurements - whether referring to intravaginal ejaculation latency time, total intercourse duration, or subjective control over ejaculation.

The framing of the question may perpetuate performance anxiety by suggesting there are specific benchmarks men should meet based on their age. The research indicates that ejaculatory function exists on a spectrum and that clinical significance depends on distress and relationship satisfaction rather than adherence to age-based averages ^{[5] [6] [7]}.

Furthermore, the question doesn't acknowledge that cultural and methodological differences between studies can significantly impact reported times, as evidenced by the variation between the Japanese study's findings ^[4] and the multinational survey results ^[1].
