Can Sperm Make Your Beard Grow? 3 Facts Explained

can sperm make beard grow

With increased claims of sperm benefits for skin and hair care and growth. I did some digging to find out whether the same can be said about beards. Here are my findings.

Can sperm make your beard or hair grow? Applying sperm can help grow a beard. Sperm promotes facial hair growth through Spermidine, a constituent of semen that stimulates beard elongation, promotes keratin production, prolongs the growth phase, and inhibits the beard shedding phase.

Read on to find out how spermidine contained in the sperm can possibly help with beard growth.

Sperm and beard growth

The growth of facial hair is stimulatedOpens in a new tab. by the two beard hormones (Testosterone and dihydrotestosterone aka DHT), plus your genes.

For a beard to grow testosterone is converted to DHT. DHT binds into beard follicles and promotes growth.

Low levels of beard growth hormones can be the reason you are not able to achieve your beard growth goals.

Secondly, genes aka androgen receptors that are not sensitive enough to beard growth hormones may be affecting your beard growth.

Whereas beard growth is entirely dependant on genes and beard growth hormones.

Anything that can prolong the beard growth phase and prevent the resting phase or even strengthen your beards can come a long way to helping you grow a beard.

Sperm for hair and beard growth       

There are tons of anecdotal claims that sperm is beneficial to hair, teeth, and skin. But for a long time, there has been no scientific research to support these claims until 2011.

Given that the most regenerating cells need polyamines, researchers set out to investigate how polyamine would affect human hair follicles, given that they are highly regenerative cells.

One of the constituents of sperm is spermidine/ spermineOpens in a new tab., and spermidine is one of the polyamines.

This research published hereOpens in a new tab. was performed in situ, meaning in the hair follicles through topical application.

Given that, inhibiting the synthesis of polyamine was found to negatively affect hair growth in mice and the fact that polyamines play a crucial role in the growth of sheep hair.

The researchers hypothesized that spermidine a polyamine can also improve hair growth in human beings.

The results of the study were:

When spermidine was applied to human hair, it stimulated hair shaft elongation.

A spermidine treatment for 6 days continuously leads to hair shaft elongation.

At the same time, the 6 days spermidine treatment also led to a prolonged growth phase of hair follicles commonly known as anaphase.

The researchers also noted that the hair produced was also well pigmented.

Hair follicles entering the resting stage of hair (the stage where hair does not grow), greatly reduced. Which meant, hair entering telogen the shedding phase was also reduced.

This in simpler terms means that applying spermidine will greatly make you grow more hair and shed little hair, which is what we all want.

Researchers also realized that spermidine also increases the production of keratin, by stimulating, the cells that produce keratin known as keratinocytes.

Keratine is one of the proteins that is contained in hair, this means the increased production of keratin leads to increased production of more hair that is longer and stronger.

How sperm promotes hair growth

Sperm promotes hair growth by:

  • Prolonging anagen phase (hair growth phase)
  • preventing the catagen phase (hair resting phase)
  • preventing the telogen phase (hair shedding phase)
  • Promotes hair shaft elongation
  • Promotes the production of keratin

These facts can help reduce hair loss caused by stress and androgens.

But how do these facts help grow a beard you may ask?

How sperm promotes beard growth

Does sperm help beard grow?

Well, as mentioned earlier, the growth of a beard is determined by genes and beard growth hormones.

What I did not mention is that the DHT inhibitors (one of the beard growth hormones), can actually affect your beard growth negatively.

Fortunately, spermidine is not a DHT inhibitor. Therefore, we can conclude that applying either spermidine on itself or sperm can help you grow facial hair.

Spermidine or sperm will prolong the growth phase of your beard, prevent the shedding phase, and ensure your beard grows longer and stronger.

How to use spermidine for beard growth

There are better and more efficient ways to grow a beard rather than using sperm.

These methods include Rogaine, which has been proven by research to help grow facial hair even in men who have not been able to grow a beard naturally.

However, if you choose to use sperm for beard growth, be sure to consult a doctor. Unsafe sperm can infect you with an STD.

You can also opt to buy synthetically made spermidine. You should apply spermidine on your skin for 6 days before you start seeing any change.

How can you stop excessive hair growth?

Based on the same researchOpens in a new tab., the researchers found out that if you apply eflornithine topically it acts as an inhibitor of the biosynthesis of polyamine and can control excessive growth of hair or beard. eflornithine inhibits the growth of hair and decreases the production of keratin.

Does semen retention (SR) help in growing facial hair?

Based on several studies semen retention could help with growing facial hair. I did not find any research studies that were purposely focused on this topic.

However, I found a few studies whose findings can validate the theoretical part of the claim.

For instance, based on this researchOpens in a new tab. conducted to evaluate the characteristics of semen, based on how long a man abstained from sex.

The study found that when a man abstains for less than a day, the motility of the sperm is increased as compared to abstaining longer. Basically, this means that reducing the abstaining period results in increased sperm quality.

Another independent studyOpens in a new tab. conducted to investigate how abstinence affects the quality of testosterone revealed that a high period of abstinence resulted in increased concentration of testosterone in men.

Semen retention does help in growing facial hair by improving the quality of semen. High-quality semen has high-quality spermidine which has been proven to stimulate and promote beard growth.

A Word of Caution Using Sperm for Beard Growth

It is important to note that, semen can pass sexually transmitted diseases and HIV/AIDS. Therefore, utmost care should be taken before choosing to undergo this route for beard growth.
