Yes, sperm is needed for conception and pregnancy. The sperm must be delivered to the egg either naturally or with medical help. Without a sperm, the egg cannot be fertilized.
Yes, you do. You need several million to be considered fertile, even though (usually) only one sperm fertilises the egg.
A sperm must join with an egg for a woman to get pregnant.
No. Sexual reproduction needs genetic material from male and female.
No. That is not possible. Even the vise versa is also not possible. both man and woman is necessary for pregnancy to take place. That's the beauty of nature.
Humans essentially can not.
No you can not.
Yes, men can it's called shooting blanks.
You mean 'Semen', not sperm. Sperm are invisible and semen is the liquid that carries sperm cells out of the man's body. Yes, clear semen is normal. So is white, cloudy semen.
Sperm are continually formed and stored. A man who does not produce sperm is said to be sterile. However, the man can still produce semen, but without sperm in it. A man can ejaculate semen without sperm--IF he is not producing sperm. The only way to know if a man is truly sterile is for a doctor to order a sperm count.Note: Men and women can have a nearly "dry" orgasm. The urge and feeling of partial orgasm may happen, but with little to no fluid. This is not usually a cause for concern if it only happens occasionally. Older men and women--over 50 years old-- may experience dry or drier orgasms more than younger persons.
She can't.Its impossible without a man She can involve just the sperm without the rest of the man by going to a sperm back or being artificially inseminated. But she definitely needs spermatazoa, and only men produce them.
The man's semen can be analyzed in a lab to see the viability of his semen.
It usually does unless the man is infertile.
You mean, "Semen". Semen is the whitish, thickish fluid that carries the sperm cells (short for spermatazoa) out of a man's body. I have heard it said that semen is somewhat nutritional, but there can't be much taste to it, or the sperm could not live in it. Semen is completely harmless when swallowed.
It's the woman that enter menopause and she does not produce seminal fluid - that is what the man is doing incl sperm. She will continue to produce discharge though but since the hormonal level changes some women find them more dry then before.
Hi iam a 19 year old boy, my penis is only 4 inch is this normal.
No. It would be impossible. They are necessary in the production of sperm and without sperm no child can be produced. The lack of any testicular tissue would also cause a reduction of testosterone.
There are two types of chromosome, called X and Y. Semen contains X sperm and Y sperm. If the Y sperm fertilises the female ovum, the child will be male. If the X sperm fertilises the female ovum, the child will be female. A man's chromosomes will be XY and a woman's chromosomes will be XX. The man's sperm always determines the gender of the baby.
Sperm is produce continuously by the body
Ejaculation is when a man reaches orgasm and releases his sperm-containing semen.
