Most men with Klinefelter syndrome don’t produce much or any sperm. A lack of sperm can make it hard to father children, but it’s not impossible. Fertility treatment can help some men become fathers.
Can a girl have Klinefelter’s syndrome
Klinefelter syndrome (47,XXY) results from an additional X chromosome on an XY background; therefore, this condition affects only males.
Can females have Y chromosome
The Y chromosome spans more than 59 million building blocks of DNA (base pairs) and represents almost 2 percent of the total DNA in cells. Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.
What if a girl has XY chromosomes
Women with CAIS are born with an XY chromosome pair. … They can, however, respond to the estrogens that their testes produce so they develop physically as women and undergo a feminizing puberty. Since they do not have ovaries or a uterus and do not menstruate they cannot have children.
What decides if a baby is a boy or girl
Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother’s X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother’s to make a boy (XY).

Is it 50/50 Boy or girl
My general response is that it’s a 50/50 chance that a woman will have a boy or a girl. But that’s not exactly true – there’s actually a slight bias toward male births. The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO).
Are XYY males infertile
Nonmosaic 47, XYY syndrome is an aneuploidy of sex chromosomes. It is often associated with male infertility. In our study the incidence rate was 0.1% (21/19,842) which is in accordance with a previously reported incidence rate.
Is it possible to have an XY female in humans
Girls with Swyer syndrome have an XY chromosomal makeup (as boys normally do) instead of an XX chromosomal makeup (as girls normally do). Despite having the XY chromosomal makeup, girls with Swyer syndrome look female and have functional female genitalia and structures including a vagina, uterus and fallopian tubes.
Does XY mean boy or girl
XY system In humans, females are XX and males are XY.
What is the gender of YY
Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome. This condition is also sometimes called Jacob’s syndrome, XYY karyotype, or YY syndrome.
What is the chromosome of a girl
Typically, biologically female individuals have two X chromosomes (XX) while those who are biologically male have one X and one Y chromosome (XY). However, there are exceptions to this rule. Biologically female people inherit an X chromosome from their father, and the other X chromosome from their mother.
What are the two sexes
Society typically tells us that there are two sexes: male and female. You may also be familiar with the fact that some people are intersex, or have a difference of sexual development (DSD).
Does DNA determine gender
It’s easy enough to determine basic physical sex with a quick scan for X and Y chromosomes. That can also determine some gender disorders, most commonly XXY—or a person who is superficially male, but carries an extra X, or female, chromosome.
What is an XY woman
Sex chromosomes usually determine whether you are female or male. Women are XX. Men are XY. … They grow up as women with a woman’s body, and most only discover well into puberty that they are different.

What increases your chances of having a girl
According to this method, to increase the chance of having a girl, you should have intercourse about 2 to 4 days before ovulation.
