What Is Sperm Volume?

Like other parameters related to sperm, sperm volume is also crucial for male fertility. It determines the amount of sperm that enters the female reproductive tract in each sex session. Since many factors can impact sperm volume, it is important to continue checking it from time to time.

This article will guide you about the average sperm volume you should expect and how to increase it.

Is Sperm Volume Same As Seminal Volume?

Sperm volume is a misnomer for the amount of semen per ejaculate. The quantity of your sperm is measured in either sperm concentration or total sperm count.

The volume unit is always about the semen. In this article, semen volume will be used for your convenience.

Semen is whitish-grey fluid men produce during orgasm. It is a carrier truck for your sperm load and contains essential tools to keep them intact.

The average semen volume in healthy young males is approximately 2 to 5 cubic centimeters. For perspective, it roughly equals up to a teaspoon in quantity.

The amount varies from person to person. It also differs for each ejaculation session in the same individual, depending on the abstinence and overall health.

How Does Ejaculation Happen?

Producing adequate seminal volume is not enough for fertility. You should also be able to exhibit it through ejaculation. Therefore, these two stages are crucial for semen volume monitoring:


Emission is a process in which your seminal fluid collects in the urethral bulb present at the base of your penis. It is sort of an assembly point for your sperm. Whatever the volume accumulates in the urethral bulb will be the total amount coming out during an orgasm.


Expulsion defines your orgasm. It occurs when sexual stimulation of the penis contracts your pelvic muscles forcefully. These powerful contractions push the seminal fluid through the urethra and out of the penis.

How Far Can a Man Shoot - Does it matter?

It is a common point of discussion among men but has no place in science. The media and porn industry portray that the pressure of your ejaculate (or intensity of expulsion) somehow determines your fertility.

This notion originates because sperm have to travel in the female reproductive tract to reach fertilization. Apparently, the higher the pressure, the longer the distance it can cover; hence, easier fertilization.

But there is no science or evidence to back it up.

Your sperm cells have built-in apparatus that help to move in the reproductive tract. So, no matter how far a man can shoot, if his sperm cells are defective, he cannot achieve pregnancy.

Contrarily, the volume of your semen actually matters. It determines the health of your sperm cells because it has protective nutrients in it.

Healthier the sperm, higher the sperm motility and sperm quality. So, they are more likely to survive the rough and tough journey through the female reproductive tract and reach the ovum.

How Can I Check My Semen Volume?

You can do it by taking a semen analysis test. Order an in-home semen analysis testing kit and check your ejaculate sample for an exact idea.

According to the National Institute of Health (NIH) and World Health Organization, the average volume ranges from 1.5 to 5 milliliters per orgasm.

If your semen volume is lower than 1.5mL, you might have an underlying health condition and need further investigation.

What Causes The Variability in Semen Volume?

You may sometimes wonder why your semen volume is low.

The following factors might cause a prominent variability in your semen volume:

  • Your testes produce 60% of seminal fluid. The rest of the supply comes from the prostate and bulbourethral glands. Any infection or disease in these structures can decrease your load.
  • Inadequate abstinence time or excessive masturbation significantly impacts the semen volume. According to research, the sperm volume increases by 11% in the first four days after ejaculation. So, take a gap for 2 to 3 days, at least, between subsequent ejaculations.
  • Your refractory period is a restart button. It is the period after an orgasm when men do not feel sexual pleasure. The reason is that your seminal glands are at work and producing semen for the next session. Shorter refractory periods lead to low sperm volume.
  • An absence of vas deference at birth makes emission impossible. The semen does not collect in the urethral bulb, leading to low semen volume later in life. This decrease is significant enough to cause infertility in men.
  • Due to obstruction of the urethra or previous surgeries, retrograde ejaculation may happen. It is a defect of the expulsion phase of orgasm. Semen backtracks and goes into the urinary bladder instead of moving through the urethra. No expulsion occurs; hence, semen volume is low or absent.
  • Hypogonadism is a condition that refers to low testosterone levels in the body. As testosterone is responsible for sexual development, its unavailability does not form seminal glands. The other signs of testosterone may vary from a simple lack of sex drive to small testes.

What Are Various Ways To Improve Seminal Volume?

Before you indulge in pill-popping for improving semen volume, you need to separate reality from the hype. Your sperm volume is low only if it is scarcer than 1/4th of a tablespoon.

Here are some tips on how to increase your sperm volume:

  • The research suggests that selenium supplementation has a role in increasing semen volume. Contrary to common belief, zinc, folic acid, coQ-10, and anti-oxidants have no documented role in improving semen volume.
  • Evidence suggests that the N.stevia herb increases semen volume along with other sperm parameters. It is available in many supplements tweaked for male reproductive health.
  • Add probiotics to your diet. The research proves that probiotics like flortec have a noticeable positive impact in increasing your sperm volume.
  • Apart from these supplements, a healthy lifestyle with a nutritious diet and regular exercise leads to a better seminal fluid volume.

Does My Biological Clock Affect Sperm Volume?

According to experts, men experience a significant decrease in semen volume with increasing age. It is due to declining testosterone levels, especially after 45 years.

To overcome this time clock, you need to move one step ahead of it. You can do it by freezing your sperm when they have an adequate semen volume.

Sperm freezing does not affect sperm quality during the thawing process and keeps semen volume intact. So, you can rest your mind about fertility and secure it by sperm freezing.

Some sperm is lost and damaged during the transport, storage, freezing, and thawing process. The semen analysis reflects values at the time of the analysis, after transport and before freezing. These values will decrease throughout the freezing and thawing process. A semen analysis alone cannot be used to predict fertility.
