Only to a degree. If you have a certain size and they get smaller, you might have some fertility or hormonal issues. But overall, testicle size does not affect the amount of semen you produce.
No, the size is irrelevant for having sex.
Assuming this question means: "at what age should a man expect to be able to produce semen", then the answer is "early in the onset of puberty". Puberty in boys begins at the age of 13, on average. It is known that the testes produce sperm even before substantial ejaculation is possible (most of the semen is fluid produced by the prostate, not the testes), but ejaculation is possible in most boys early in puberty. From puberty and over the next 5 or 6 years, the testes grow and most of the growth is in sperm producing tissue. Thus it can be assumed that fertility is greater at age 18, than it is at age 13, though most boys are probably at least minimally fertile (capable of impregnating a female) at beginning of puberty.
the average man has around 3 tablespoons of semen he can ejaculate.
The man's semen can be analyzed in a lab to see the viability of his semen.
An infected man typically has chlamydia in his semen. Chlamydial infection can ascend to the prostate, epididymis, and testes, and can directly affect the quality of sperm. Scarring in the male reproductive tract can affect sperm count. See related link.
It would depend on the size of the balls, and the size of the rectum in question.
A man's testes can hold between 80 and 100 million sperm if he is healthy.
Well If youre a woman you should not have any semen. so if you have semen you are a man.
Not with his own semen. Though if he came into contact with another man's semen (having sex with another man or even a woman who recently had sex), then the "foreign" semen could impregnate the woman.
No, swallowing a man's semen will not have any medical effect on the couple's connection.
If a man wears a 50 to 52 in Russian jeans his American size will range from 34 to 37. It will depend on the brand and also the fit of the jeans.
I semen made through the day or only when a man is to reach orgasm?
