Below is an online calculator that will tell you how much semen will be ejaculated in a year based on the frequency of daily ejaculations and number of men you wish to enter for comparison.    The default amount is one man ejaculating once per day who will then produce 2.15 gallons of semen in a year.

The single biggest factor in quantity is the period of time since last ejaculation. If you ejaculate several times in rapid succession, you might only produce a few drops by the last one, but if you wait a few days, that amount will go up to more like two tablespoons.

Some people mistakenly believe that drinking lots of fluids or eating certain foods will increase the volume, but semen is not like urine: It is not coming from the digestive or urinary system. The bulk of semen is comprised of secretion from the prostate gland.

About the only other thing that has any influence on the volume of your semen is how much stimulation you get before having an orgasm. If you prolong it (and include things like prostate massage), you might see an increase in volume. But genetics also seem to play a large role. So you will probably never get up to porn star levels -- but their "money shots" are often done using fake semen (condensed milk being a favorite) anyway.  (Website where this information was originally obtained no longer exists - was thriveonline.com)


Semen contains aboutonia, ascorbic acid, blood-group antigens, calcium, chlorine, cholesterol, choline, citric acid, creatine, deoxyribonucleic acid, fructose, glutathione, hyaluronidase, inositol, lactic acid, magnesium, nitrogen, phosphorus, potassium, purine, pyrimidine, pyruvic acid, sodium, sorbitol, spermidine, spermine, urea, uric acid, vitamin B12, and zinc -- but all in very modest quantities. Some of this is designed to nourish the semen in route, while other ingredients are designed to neutralize the acidic environment of the vagina (which would normally be inhospitable to sperm).

In case you are wondering, most of these ingredients are indeed very healthy, and an average ejaculation contains only about 15 calories.


To Fill A Bathtub....

It would take a man 17.5 years to ejaculate enough semen to fill the average bathtub assuming he ejaculated once per day, everyday, during that 17.5 year period.   (average bathtub holds 35 gallons of water.
Stadium Becomes Cum Bowl....

If you filled a 65,000 seat stadium with men and had them ejaculate while there, they'd produce 381 gallons of semen
NFL Game Day Cum Pig....

If you had each NFL professional football player in the NFL ejaculate prior to game time, they'd produce at minimum 8 gallons of semen on any given Sunday.
High Seas Semen....

If you had every male crew member on a nuclear powered United States Navy Aircraft carrier ejaculate at once they'd produce 20 gallons of semen; if you added their fighter wing staff, there would be another 12 gallons of semen milked.
A Cum Drum....

If a man were to ejaculate once a day for 25 years, he'd have filled 1, 42 gallon drums and have started on his 2nd.
One Container for the Trip and Back....

If a man were to ejaculate once a day for 1 year, he'd have filled 2, 1 gallon gasoline containers.
Holy Cum, Batman!

If half of the men in the United States (approximately 62.5 million men) ejaculated simultaneously, 366,211 gallons of semen would be ejaculated which would result in over 8,700 barrels of semen (like barrels of oil) to be ejaculated or over 10,460 bathtubs to be filled on one night!
Holy Cum, Batman - Imagine a Month!....

If half the men in the United States were to continue to ejaculate once a day for a month, more semen would be ejaculated than there was oil spilled by the Exxon Valdez in Alaska!
So Much Cum!   So Little Time!....

If the 125 million or so men living in the United States were to have ejaculated once per week during a 25 year period in their lifetime, there would have been 400 million gallons of semen produced.
