One ejaculation, which is from 4 to 7 cc of semen. This is then, if used and stored for AI, is divided up into straws according to what each straw should hold. Usually, each straw will hold around 0.5 cc to 1.5 cc of semen.
Probably not . . . they produce a clear fluid that preceeds male ejaculation in order to lubricate the urethra, neutralize traces of acidic urine, and generally clean the urethra out prior to ejaculation. There are 2 of them, each side of the base of the penis, and are commonly know as Cowper's glands.
During ejaculation, a man can release between 1.5 to 5 milliliters of semen, which can contain millions of sperm. However, only a small fraction of this sperm will actually reach the egg during fertilization.
A liter is quite a large volume. The average man only produces a few tablespoons of semen every day.
If you ejaculate several times a day, the volume of semen in each ejaculation will decrease somewhat. Other than that, there is no adverse effect.
One amount of ejaculate may contain between 40 million to 600 million sperm depending on the volume and the length of time stored before ejaculating. It varies by lifetime. One estimate is 18 trillion sperm.
Repeated ejaculation over a short period of time will have the effect of reducing the volume of semen and somewhat affect the number of sperm cells present in each successive ejaculation. The body however, produces enough of each that even a miniscule amount of ejaculate has the capability of producing a pregnancy. Depending on the overall age and health, the refractory period the body needs to build up to full capacity again, can range from only an hour to several days. Someone would have to masturbate or have intercourse repeatedly, to the point of injury, before he would completely stop producing any semen or sperm cells during ejaculation.
Lets think about that, we are talking about comparing 1/4 ounce of liquid semen ( about 10 grams of protein) to an 8-12 ounce piece of beef ( 80 grams of protein) ..NO SEMEN doesn't come close to the beef! I was amused to find a forum that asked young guys how much semen is in each ejaculation, some thought it was 3-4 ounces.. that's a shot glass X 2! It is a very small amount, 1/2 ounce is a HUGE ejaculation.
There are 5 tablespoons in 75mL. Each tablespoon is 15mL.
It depends, some 14 years old guys won't be able to ejaculate yet, whereas some others can shoot a great amount. As a 14 yo teen myself, I shoot between 8 and 11 spurts (I think it's the average for a teenager) of semen per ejaculation, but each person is different.
You get the other 23 from the opposite sex. The semen and the egg combines and gets 46 chromosomes. If each gamete contained 46 chromosomes, the zygote would contain 92 chromosomes.
Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and empty into the urethra at the Colliculus seminalis. During ejaculation, semen passes through the ducts and exits the body via the penis.
