Fertility is related to the amount of semen and not to its colour on a ejaculation. Less than 3.5 ml indicates an unfertile male.
No.
No you just have not matured enough yet
Yes. A tired man can still produce semen. It might take more effort but as long as he can put semen into a woman's vagina, she can become pregnant.
you won't be able to have children. most people produce at least some sperm, but sometimes it is not enough or the sperm isn't viable. talking to the doctor about possible problems will help, as your semen can be tested for sperm content. most people that don't produce sperm to have children can still have normal sex like everyone else though.
Women do not make sperm only men do.
Females do not produce sperm or semen. They produce a liquid when sexually excited, but it has no sperm in it. Edited: Neil L No one said it was actually sperm or semen the question was what is it called. Males produce the listed terms while female ejaculation has no specific term. However the contractual term for the reciprocating relevant event associated with SPERM would be ovum or egg but this is not the same as the fluid produced during sexual activities for a female as semen is for a male. Semen for a male also does not necessarily carry sperm as a male will still produce this even after a vasectomy. These two terms are separate in definition but related in event.
Children are not as fully developed as adults, adults can produce children Children are still growing and forming until they reach adulthood.
If you wait long enough, every gelding will lose the ability to produce offspring after a few months. A test called a Semen Evaluation can be done to see if he is still fertile.
semen has a small amount of blood in it so the HIV is still in the blood but is carried by the semen to your partner.
If you are 15 years old, and you have never ejaculated, then you have started puberty late. But try masturbating for a long period of time and if sperm still does not come out then you have not yet developed sperms, and nothing can be done about it. You will start to produce sperm in your semen as you grow older. At first when masturbating you will have dry climax's, then you will progress to have some fluid which will be semen, this is usually whitish and sticky, it may be almost clear. Later as you mature you will produce sperm in the semen. It all happens during puberty. If you are 15 now you should be well away in a years time.
Semen is the total ejaculate. The sperm content in the ejaculate is a tiny part (about 5% of the total volume, the rest is lubricating fluids and nourishment for the sperm while it is on its way. Semen content and semen volume would be two different things & your question is ambiguous. If the sperm content of the semen is low you wouldn't be able to conceive children. If the volume is low, you just wouldn't have much ejaculation. you could still have an orgasm, just wouldn't be much semen there.
Sperm make up a tiny volume of semen, but the testes still do produce some seminal fluids. After a vasectomy, you'll probably have less volume, but it probably won't be noticeable. The prostate gland, and cowpers gland are still fully active and connected post vasectomy, and they make the bulk of semen. It's the removal of the prostate that effects volume the most. After it's removal, many men experience "dry" orgasm.
