23 chromosomes
50 % of human sperm Cells are an X chromosome, the other half are a Y chromosome: {diploid = 2n = 1 chromosome pair; haploid = n = 1 chromosome - including the meiotic single chromosome = n}. All sperm and egg Cells carry one set each of n (23 single) chromosomes. When a sperm and an egg combine either: a) a sperm Cell with the X chromosome merges with the [X-chromosome] egg Cell and the baby will be a girl; or b) a sperm Cell with the Y chromosome merges with the egg Cell and the baby will be a boy.
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
The chromosome number 23 is found in human sex cells, such as eggs (in females) and sperm (in males). These cells are known as haploid cells, containing half the normal number of chromosomes found in somatic cells.
It's determined by the genetic chromosome of the sperm. Women have only one X chromosome in the egg (both egg and sperm have 23 pairs of chromosomes, which unite to form 46). On the other hand, men have either X or Y chromosomes. If an egg (X chromosome) joins with an X chromosome sperm, the result will be a girl. If an egg (X chromosome) joins with a Y chromosome sperm, the result will be a boy. In other words: the guy determines the sex of a baby :)
No, the father's sperm carries either an X or Y chromosome, but it is the mother's egg that ultimately determines the gender of the child. If the egg is fertilized by a sperm with an X chromosome, the child will be female, and if it is fertilized by a sperm with a Y chromosome, the child will be male.
Yes.
By human egg cell I guess you mean the oocyte (the one produced by the mother). The oocyte always carries the X chromosome, the sperm can either carry the Y or the X chromosome. Interestingly, the sperm which carries the Y is actually quicker than the one carrying the X, maybe because the X chromosome is far larger. So, if the Y chromosome sperm reaches the egg first, the child will be a boy (XY), and if the X chromosome sperm beats him to it, the child will be a girl (XX).

An egg will have the X chromosome and the sperm will have an X or Y chromosome.

23 in both Egg Cells and Sperm Cells.
It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy.

Y chromosome. When a sperm with a Y chromosome fertilizes an egg, the resulting offspring is male. On the other hand, if a sperm with an X chromosome fertilizes the egg, the offspring will be female.
Yes, it is true that a man's sperm cells determine the sex of a child. Sperm carries either an X or a Y chromosome; if the sperm fertilizes an egg with an X chromosome, the child will be female (XX), and if it fertilizes an egg with a Y chromosome, the child will be male (XY). Therefore, it is the combination of the sperm's chromosome and the egg's chromosome that ultimately determines the child's sex.

The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
