What type of sperm must fertile as egg to result in a female child?
The sperm must have an X chromosome as opposed to a Y chromosome.
How long sperm can survive in the female body depends on how healthy the sperm are and whether the female is fertile at the time. If there is fertile quality cervical mucus present then sperm can potential survive for up to a week within her body.
The sperm which has got X chromosome in it. Fortunately it is not possible to isolate such types of sperms. It will be better that you do not have the technology to determine the sex of the child by way of selecting the sperms. Technology have already disturbed the sex ratio is some countries of the world.
No, the sperm must be deposited in the vagina while the female is fertile for her to become pregnant.
X Chromosome results in a female Y Chromosome results in a male All sperm are either going to be an X or Y chromosome All eggs are X chromosome only
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.
No. An egg, which is produced by a female, must be inseminated by sperm, which is produced by the male.
Females' eggs always provide an X. If the sperm is X, the child is female (XX); if it is Y, the child is male (XY).
Yes, definately. In some cases, when a couple wants a child, the male cannot ejaculate sperm. As such, there are donors of sperm. The sperm is just put in the female reproductive organ and the female falls pregnant
Female humans have two X chromosomes, males have one X and on Y. The female contributes one X to the child. The male contributes either an X or a Y. This determines the sex of the child. If the sperm carries a Y chromosome, the child will be male, if the sperm carries an X chromosome the child will be female.
It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed… Read More
i think you mean a 'surrogate mum' If so, this is a fertile female who carries and gives birth to a baby for a lady who (usually for medical reasons) can not do so herself. The surrogate female becomes pregnant usually via AI (Artificial Insemination) of the father-to-be's sperm, carries the child, and upon birth, hands the child over to the couple.
Not without the help of a man at some point. Allowing for normal fertile females, either of them can carry a child, but you still have to have sperm to fertilize the egg.
Because male has sperm cell while female has ovum cell
no that is not possible. The man has a penis and a women has a vigina and the male can produce sperm and a female can't she has an egg that when a couple have relationships sperm transport to the egg of the female.
One mating can produce fertile eggs for up to 10 days without a repeat mating.
No, sperm are produced by males in their testes. Sperm is only produced by males, female produce ovum, or eggs. When a spem and an ovum come together the result is a baby.
A female cannot get pregnant during menstruation as there is no egg present to fertilize. However a woman can get pregnant as a result of sex on her period as if her cycle is short there may be fertile cervical mucus present that could keep sperm alive long enough to still be around when she ovulates after menstruation.
before a woman conceived a male child, you have to have sex close to ur ovulation so that if the egg drop the male sperm will be there to meet the eeg. because male sperm die quickly than the female sperm.
If most human offspring receive 23 chromosomes from the mother how many chromosomes do they receive from the father?
23 from the father. If the sperm contains a X chromosome the child will be female...if its a Y sperm the child will be male.
Teen sperm is very fertile. Age only has any significance on fertility of sperm with regard to some much older men, like your grandad for instance!
Yes. You need both the egg and the sperm to produce a fertilized egg which will result in an embryo who will be born. The female has the eggs and the males have the sperm, so you need both present.
The Male's sperm has to enter the woman during time of ovulation. The sperm travels through the Fallopian tubes of the female and inseminates the egg and creates a fertile egg which later attaches to the uterine wall.
Fertile men should have sperm that is between light gray to off-white. There is not a perfect color that will indicate fertility.
it should still be fertile if u put it in water its not
A female does not have sperm. Sperm is found in males only. Sperm is used to get the female pregnant.
Sperm and an egg coming together will produce a living fetus after the sperm (Male sex cell) breaches the egg (Female sex cell)
The sex determination as male or female child depends on the presence of Y or x chromosome in the sperm of the father. If the male gamete (sperm) contributed by the father has Y chromosome fertilizing the egg of the mother, a male child will take birth anf if the fertilizing sperm has x chromosome, it will be a female child. A mother always contributes the X chromosome whereas father may contribute X or Y… Read More
Only males have sperm. There is no such thing as female sperm.
When a fertile sperm reaches near a mature unfertilized egg, the capability of sperm to pears through the egg cell wall and discharge its nucleus makes it possible to fertilize the egg. This union of male and female gametes to form zygote is called fertilization.
A male would have to deposit his sperm within the female's reproductive tract during the same time that the female releases a fertile egg from her ovary.
Usually, yes. As long as the remaining testicle is fertile, and the man is producing sperm actively, he should be able to reproduce. As long as sperm is being produced and the man is able to ejaculate normally, there is no reason he should be unable to have a child. The second testicle is really only there as a backup; only one is needed to house sperm.
Although only males produce sperm, that does not mean that all sperm is male. There are two types of sperm: male and female. Male sperm carry the 'y' chromosome; female sperm carry the 'x' chromosome. If all sperm where male, then there would be no females born. Thus, the difference between male and female sperm is that male sperm carries the 'y' chromosome and produces male offspring and female sperm carries the 'x' chromosome and… Read More
If you havent gone through puberty, then your testis are not mature to make healthy fertile sperm. So even if you ejaculate it will not be fertile.
Sperm is neither male nor female, it is a single cell - the egg determines whether the baby will be male or female. The sperm is the male sex cell, and it has two chromosomes ..... one "X" chromosome and one "Y" chromosome. Females have 2 "X" chromosomes. If the male sperm fertilizes the female egg with an "X" chromosome, the resulting baby will be a girl, but if the male sperm fertilizes the egg… Read More
The male is in posession of the Testes, which produce sperm. Sperm can have either chromosone which results in the gender of the baby - X, or Y. You only need one Y chromosone for the child to result in a male, and two X for a female to be produced. There is a 50/50 chance of either. There are fewer sperm carrying X but they are faster than the sperm carrying Y, thus the… Read More
What the fek is female sperm? Youre stupid.
Sperm of a fertile male.
male and female gametes form a zygote which is an offspring from the sperm cell (father ) and egg cell (mother ) . a zygote ( child ) is what is formmed when there is a sexual intercourse between mother and father ( the egg and sperm cell fuse ! )
You can't conceive during menstruation, but you can as a result of sex during menstruation. When menstruating there is no egg present to fertilize, but you may be fertile thanks to fertile cervical mucus that could keep sperm alive long enough to still be around when you do ovulate.
It varies among species of ducks. Some female species can store sperm for a week or less, while others can store sperm for 100 days or more. For those ducks storing for a week or less, pairs often continue to mate throughout follicle development. This ensures the female has sperm available to fertilize the eggs as they leave the ovaries and have viable eggs.
Some men may be impotent, usually a result of having a low sperm count.
Just mixing their sperm is not enough to create a child. The only way to create a fetus is to have a female gamete - i.e. egg - fertilised by a male gamete - i.e. sperm. So the two men could mix their sperm, but they would not know which had fertilised the egg, and would not know who the father would be.
In males, the testis become larger and can produce mature sperm. in males, the ovaries become fertile. Only fertile sperm and eggs can reproduce.
Sex determination is a chance event. Neither parent is in control of this process. If a sperm containing an X chromosome fertilizes an ovum, a female child results. If a sperm containing an Y chromosome fertilizes an ovum, a male child results. No one can tell which sperm is going to fertilize the ovum. Therefore, neither parent can be blamed.
depends on the type of dog and if the woman is able to be fertilized. the dogs penis pushes into the female womans vagina until it reaches the cervix. and the dogs penis grows until it gets stuck behind the womans cervix while he pumps his sperm into her there is a chance the female woman will become pregnant if the sperm mixes with the zygote she will become fertile because she is full of… Read More
The female body does not release or have "sperm" - women have "eggs" that the mans sperm fertilizes to achieve conception.
Sex is determined by the sperm cell that fertalized it. The egg supplies an X chromosome, and the sperm cell supplieds an X or a Y chromosome. If the result is XX, it is female, if it is XY, it is male.
It doesn't depend on how much of sperm is produced for a man to be fertile but it depends on the quality of the sperm. Many lifestyle factors affect the quality of sperm, eg. Smoking, excessive alcohol intake , temperature at which the testicles are kept at, etc.
Male sperm swimm, Female ovum do not swimm.
Like all other animals there are female Sperm whales.
