Approx. 1,000,000 sperm are released during one ejaculation period.
At that age you will not have any unless you have started puberty early. Everyone is different.
If the semen of the male comes in contact with the vagina of a female, there is always a chance of pregnancy.
normal according to the body mass index for 5'8" is 125 pounds to 158 pounds. . . if you are an athlete more of your weight is probably muscle so what is normal may be heavier.
The male to female human sex ratio varies, due to demographics, environment, sex deterministic abortion, and imbalance in the male/female sperm viability ratio. The secondary ratio of boys to girls is about 105 to 100, or about 0.525 male. Estimates of the current birth sex ratio is about 0.535 male. The current global sex ratio (population) is about 0.507 male (2010) to 0.508 male (projected 2011).
A normal white blood cell count for an 18 year old male is between 4,500 and 10,000 white blood cells per microliter. If you have low blood cells, it is called leukopenia.
The prostate makes semen which is ejaculated at male orgasm. Semen's purpose is to carry sperm cells that are made in the testes.
That is the fluid called semen, the male ejaculate.
Sperm carries the male DNA, while semen is the fluid that the sperm swim in from the male into the female.
In a normal, healthy, post-pubescent male, semen and/or sperm cells are produced continuously. If not used in their normal manner, the sperm cells will gradually die and be reabsorbed into the body.
Semen is sperm mixed with other secretions of the male reproductive system. Sperm is formed in the seminiferous tubules of the male testis. As Sperm leaves the body it passes through the prostate gland. The sperm is mixed with a milky white substance that is used to neutralize the acidity of the vagina allowing protection for the sperm. Then this mixture passes through the seminal vesicles where it is then mixed with fructose to provide energy for the sperm. Right before the sperm mixture is ejaculated out of the male penis, the bulbourethral glands send out a "pre-ejaculation" that neutralizes traces of acidic urine in the male urethra. All of that mixed together is known as semen.
male semen carries the sperm
Sperm are produced in the male testicle (testis). Sperm cells are only the smallest part of the fluid that is ejaculated. The fluids from various glands (seminal vesicles, prostate, and Cowper's gland) are added to the sperm as the sperm are ejaculated.
The fluids in the semen provide an environment in which sperm are able to swim. Semen also contain nutrients that the moving sperm use as a source of energy. It took me a while to find the answer!
sperm or male reproductive cells.
No. The function of semen is to nourish sperm to keep them alive long enough to make a female pregnant, and it is produced and ejaculated by the male only. The only exception to this is in primitive species such as snails and slugs which are hermaphrodites. Adult snails and slugs have both male and female reproductive organs and when they mate they exchange sperm so that each goes and lays eggs. This is not truly an example of semen from a female because slugs and snails are neither male nor female.
Semen is the term for the mixture of fluid and sperm
The largest amount of semen ever ejaculated was over 400 gallons form a blue whale but I'm not sure what the largest amount is for a male human maybe about 1/4 of a liter
