This guide will help you find out. Quittr’s quit porn can help you quit porn and improve your Semen Retention Power.

What Is in Semen and How Much Energy Does It Contain?
Semen is not just sperm. Sperm cells make up only about 3-5% of the total semen volume. The rest is made up of various fluids and compounds secreted by the seminal vesicles, prostate gland, and bulbourethral glands. Here's a breakdown:
Sperm Cells
The reproductive cells are produced in the testicles.
Fructose
A type of sugar that provides fuel for sperm mobility.
Proteins and Enzymes
Help maintain the semen’s stability and sperm function.
Minerals Like Zinc and Selenium:
Necessary for reproductive health and antioxidant defense.
Vitamins Such as Vitamin C and B12
Offer protective benefits to sperm.
Magnesium and Calcium
Involved in motility and fluid balance. In total, semen is a nutrient-dense fluid, but only in trace amounts.
How Many Calories Are in Semen?
Numerous sources estimate that each ejaculation contains between 5 to 25 calories, depending on volume and individual health factors.
Volume
The average semen volume per ejaculation is around 3 to 5 milliliters (mL), but it can range from 1.5 to 7.6 mL. Nutritional content per teaspoon (~5 mL) includes:
About 0.5 grams of protein
Small amounts of sugars, enzymes, and minerals
Total estimated caloric value: 5–25 calories
These numbers are not substantial in terms of energy expenditure. Twenty-five calories are equivalent to walking for 5 minutes.
What About the Energy in Sperm?
Some NoFap and retention advocates talk about losing “life force” or “vital energy” through sperm release. Scientifically, each sperm cell contains energy in the form of ATP (adenosine triphosphate), which powers its tail (flagellum) to swim. However, this energy is microscopic and used internally by the sperm cell for movement. It’s not something the body “loses” in a way that affects your metabolic health. Even though a single ejaculation may release tens to hundreds of millions of sperm cells, the collective energy loss is still minimal.
Does Ejaculation Deplete the Body?
While ejaculation does involve the release of nutrients and energy-rich compounds, the actual nutrient and energy loss is negligible for most healthy individuals. Your body constantly replenishes these materials through diet and internal recycling processes.
However
Chronic over-ejaculation (e.g., multiple times per day, daily over months) may contribute to

How Much Energy Do You Lose When You Ejaculate?
How Many Calories Does Ejaculation Burn?
Each ejaculation contains roughly 5–25 calories. This depends on several factors, including semen volume (typically 3–5 mL, sometimes up to 7 mL), nutritional content (including proteins, sugars, and trace minerals), hydration, and overall health. To put that in perspective: 5–25 calories is equivalent to a few bites of an apple, climbing stairs for 1–2 minutes, or stretching/light walking for 5 minutes. So, no ejaculation does not burn hundreds of calories or physically exhaust your body in measurable metabolic terms.
What Nutrients Are Lost During Ejaculation?
Semen includes proteins, zinc, selenium, vitamin C, fructose, enzymes, and more. These are essential nutrients, but the quantity in semen is tiny. For instance, each ejaculation contains about 0.5 grams of protein, with trace minerals that are easily replaced through food. Your body naturally replenishes sperm and seminal fluid continuously, just like skin cells or red blood cells. Unless you’re severely malnourished, the nutrient loss from ejaculating isn’t biologically harmful.
Why Do You Feel ‘Drained’ After Orgasm?
It’s not physical energy loss. It’s all in your brain. After orgasm, your body releases a surge of neurochemicals, including prolactin, dopamine, oxytocin, and serotonin. Prolactin creates a feeling of satisfaction, but it also suppresses dopamine. With your dopamine levels dropping, it’s normal to experience a temporary decline in motivation, drive, and energy. Oxytocin and serotonin are calming chemicals that make you want to relax, sleep, or disengage. These post-ejaculatory neurochemical shifts are the real reason why you may feel tired, dull, or less sharp after orgasm, not the caloric loss. It’s not your “life force” leaving; it’s your brain shifting out of a high-stimulus dopamine state, similar to how you feel after bingeing on junk food or finishing a video game marathon.
The Real Risk of Frequent Ejaculation
While a single ejaculation doesn’t “drain” you, frequent, compulsive ejaculation especially with porn or edging can have effects. These include lower baseline dopamine sensitivity, decreased motivation and discipline, mood swings or “flatline” periods, and reduced sexual satisfaction in real life. Fatigue caused by disrupted sleep, not ejaculation itself, is also common. This is especially so for those who are addicted to porn, rely on masturbation for emotional coping, or edge for hours without release. In such cases, it’s not the ejaculation that’s hurting you; it’s the mental patterns and overstimulation behind it.

How Pornography Rewires Your Brain
Excessive ejaculation, especially when it’s tied to pornography, doesn’t drain you because you “lost calories” or “gave away vital nutrients.” The real hit comes from the way chronic high-stimulus arousal rewires your dopamine system.
Porn-Induced Dopamine Addiction
Super-normal Stimulus
Streaming sites deliver unlimited novelty (genres, tabs, clips). Each click releases a fresh surge of dopamine, far higher than what the brain evolved to handle.
Dopamine Spike
After orgasm, dopamine plummets, prolactin rises, and the brain’s reward circuit enters a refractory lull. This is why you feel foggy or unmotivated right after release.
Compulsive Loop
The steeper the crash, the more your brain screams for another hit. Over time, you’re not chasing pleasure, you’re running from the low.
Expert Insight
Dr. Anna Lembke (Stanford psychiatrist, Dopamine Nation) “The binge/crash cycle of modern digital pornography mimics substance addiction. We see tolerance, withdrawal, and craving but the drug is novelty and neurochemical intensity.”
Reward Desensitization & Motivation Suppression
Down-Regulated Dopamine Receptors
Your nucleus accumbens (reward hub) becomes less sensitive. The same clip no longer excites; you need edgier content or longer sessions.
Reduced Baseline Motivation
Because everyday rewards (work, study, socializing) produce normal dopamine levels, they now feel flat, tedious, or stressful.
Executive-Function Fatigue
Prefrontal cortex activity decreases, eroding impulse control and focus. You promise “just five minutes,” then binge for an hour. A 2016 fMRI study in JAMA Psychiatry showed lower gray-matter density in the reward circuits of high-frequency porn users, correlating with diminished motivation in non-sexual tasks.
The Energy & Mood Cost of Over-Ejaculation
Morning-after Lethargy
Not due to lost calories, but to neurochemical depletion.
Mood Swings
High-dopamine–low-dopamine whiplash manifests as irritability, anxiety, or mild depression.
Willpower Drain
Each crash weakens the prefrontal “brake,” making relapse more likely and delaying real-world goals.

Energy Loss After Over-Ejaculation
So, how much energy is lost in sperm? Studies estimate that a single ejaculation can yield about 15 calories. That’s roughly equivalent to eating two almonds or one fresh green bean. No euphoric pleasure or cool nutrients can compensate for the blow to your brain’s reward circuitry.

Semen contains a shocking amount of energy. Sperm is composed of 50% fructose, which provides fuel for the sperm and also gives semen its sweet taste. Fructose is a sugar, and just like glucose, it provides energy for the body. The amount of energy contained in sperm can vary. It is estimated that each ejaculation contains around 15 calories of energy.
While this number may not seem like a lot, it takes energy to produce sperm, and a healthy male will produce anywhere from 1,500 to 2,000 sperm per second. One sperm may only contain a fraction of a calorie of energy, but if you consider how many sperm are in a single ejaculation, the count is in the millions. Even if you are not concerned about the energy contained in sperm, the fact that sperm contain nutrients that the body can use should be enough to make you think twice about pornography and semen retention.
