The Surprising Health Benefits of Semen

Cum. Jizz. Seed. Erectoplasm. Whatever you call it, semen plays an integral role in the process of human conception. Depending on who (and what) you’re into, it might also be a big part of your sex life. The benefits of sex are in many cases quite obvious—it feels good, it can lower stress, deepen your relationships, yada yada yada—but it also turns out that semen (and in particular, some of the compounds found in sperm) may have some pretty significant health advantages, too.

Spermidine: The Holy Grail of Anti-Aging?

Back in 2009, an article entitled “Induction of autophagy by spermidine promotes longevity” was published in the journal Nature Cell Biology. In it, scientists concluded that the application of spermidine extends the lifespan of human immune cells and inhibits oxidative stress in aging mice. 

What Is Spermidine?


Spermidine is a polyamine compound that can be found in ribosomes and living tissues, including semen. Even prior to 2009, research had already shown that spermidine is involved in important biochemical processes on a cellular and molecular level. In particular, spermidine promotes a process called autophagy, in which cells remove unnecessary or defective components and break them down for recycling. Evidence has also suggested that spermidine plays a role in reducing inflammation, metabolizing lipids, and regulating cell growth. 

How Can Spermidine Prevent Aging?

A more recent article published in 2019 in the journal Health Management argues that spermidine supplementation could be key to promoting healthier aging and increasing longevity, particularly in regards to cardiac function. Although humans are living longer, age-related maladies like cardiovascular disease and metabolic disorders have proven formidable challenges to quality of life as people age.

In mice, spermidine supplementation has had promising results, prolonging aged mice’s lifespan by as much as 10%. Some scientists believe that lifelong supplementation could increase that to as much as 15% or even 25%. 

Preclinical testing shows that spermidine-supplemented diets can improve diastolic function, reduce hypertrophy, lower cardiomyocyte stiffness, enhance mitochondrial function, delay the development of high blood pressure, and reduce chronic inflammation. It may even promote human hair growth

Is Spermidine Only Found in Sperm?

Anyone who’s not into swallowing can breathe a sigh of relief. Consuming semen is far from the only way you can add spermidine to your health regimen. In fact, don’t go making a semen smoothie just yet—you’d need to consume about a gallon to reap any real health benefits. On the plus side, spermidine is a naturally occurring chemical compound in the following foods:

Wheat germ Dried soybeans Aged cheddar
Mushrooms Rice bran Chicken liver
Green peas Mangoes Chickpeas
Cooked cauliflower Cooked broccoli

Another way to increase your spermidine consumption is to take a spermidine dietary supplement. Early clinical trials seem to indicate that spermidine carries a low risk of toxicity, but you should still consult your doctor before beginning any new medication or supplement to discuss any possible side effects or drug interactions.

Does Semen Offer Other Health Benefits?

health benefits of semen

Although swallowing semen every time you have sex isn’t likely to put the brakes on aging, it does seem that there could be some other health benefits of semen for men and women alike. The average ejaculation often contains about a teaspoon of semen. In that one teaspoon, though, you’ll find vital nutrients like Vitamin C, protein, zinc, calcium, and potassium. While giving good head* won’t replace eating well and taking your vitamins, swallowing just might give your immune system a little boost. 

*Remember to always practice safe sex. Engaging in oral sex with an untested partner can result in the spread of STDs like HPV, chlamydia, gonorrhea, or genital herpes.

Swallowing Semen Can Benefit Pregnant Women

In pregnant women, swallowing semen after oral sex may reduce the risk of preeclampsia by keeping blood pressure low. Preeclampsia is a potentially harmful complication that results from high blood pressure that occurs in women who previously had normal blood pressure.  Researchers theorize that paternal semen could essentially adapt an expectant mother’s immune system to prepare it for the foreign proteins present in sperm and by extension, the placenta and fetus. 

In a similar vein, a study by psychologist Gordon Gallup suggested that ingesting semen may even help reduce instances of morning sickness in pregnant women.  

Semen Contains Mood-Boosting Compounds

In addition to vital nutrients, semen also contains hormones and neurotransmitters like cortisol, oxytocin, melatonin, and serotonin. Again, there’s probably not enough of these compounds to replace your antidepressant with a daily dose of semen, but adding it to your sex regimen probably won’t hurt, either.

Ejaculating More Often Can Decrease the Risk of Prostate Cancer

The health benefits of semen don’t stop at consuming it. It turns out that the simple act of ejaculating can be quite beneficial to men’s health. A Harvard ejaculation study found a link between increased instances of ejaculation and a decreased risk of prostate cancer. 

The study included ejaculations from sexual intercourse, nocturnal emissions, and masturbation. According to the study, men who ejaculated 21 or more times a month had a 31% lower risk of prostate cancer. All the more reason to love thy partner (and thyself).
