Ejaculation and testosterone

A low level of testosterone is associated with reduced volume in ejaculation and delayed ejaculation. High levels of testosterone are associated with premature ejaculation (Corona et al, 2025). Premature ejaculation, in turn, may influence orgasmic pleasure.

They found that testosterone levels rose significantly at ejaculation and returned to pre-ejaculation levels 10 minutes later. Cortisol and prolactin levels rose before erection, at ejaculation

One common cause of weak ejaculation is low testosterone levels. Testosterone replacement therapy may be recommended for individuals with this hormonal imbalance. According to the World Health Organization, testosterone replacement therapy can help improve sexual function, including ejaculation, in men with low testosterone levels.

Some studies have suggested that testosterone levels may influence ejaculation latency, which is the time from vaginal penetration to ejaculation. One study conducted in 2025 found that men with premature ejaculation had significantly higher levels of testosterone compared to men without the condition.

Premature ejaculation. Delayed or slowed ejaculation. Low testosterone These include mirtazapine (Remeron) and bupropion (Wellbutrin).

Ejaculation has been historically associated with a decline in testosterone levels, leading to the belief that frequent ejaculation may have adverse effects on testosterone production and virility. However, recent scientific research suggests that the impact of ejaculation on testosterone levels is relatively short-lived and does not have

A quick background on the science: It has been shown in rats, and now also in other mammals, that there is a decrease in androgen receptors (testosterone is an androgen, so basically they're less sensitive to testosterone) after ejaculation. This means that your brain absorbs less testosterone after ejaculation.

High testosterone and premature ejaculation. Some research suggests testosterone levels that are too high, from testosterone replacement therapy (TRT) or anabolic steroid use, can cause premature ejaculation. For starters, testosterone directly affects libido, the desire to have sex, and arousal.

Low testosterone levels can lead to a decrease in the strength and intensity of ejaculation, making it less satisfying. Some men with low testosterone may also experience delayed ejaculation or an inability to ejaculate during intercourse. For example, TRT might lead to an increase in ejaculation volume for some men, while others might not
