secondary oocytes are haploid cells carrying 23 chromosomes. After fertilization by sperm a Zygote is formed with a diploid number 46.
The gametes, namely sperm and egg cells (oocytes).
The gametes (sperm and unfertilized egg, or ovum).In humans, body cells are diploid. To form gametes, specialized cells in the gonads (primary spermatocytes in males, and primary oocytes in females) must go through meiosis.Strictly, there are more than two types of cell that are haploid. The cells formed by meiosis I are haploid, and these are (in males) secondary spermatocytes, and (in females) secondary oocytes. These divide (meiosis II) to form more haploid cells that differentiate into the gametes.The secondary spermatocytes, secondary oocytes, and gametes are the only haploid cells in humans. In other organisms, it can be quite another story!

ovum is the product after the secondary oocyte fuses with sperm
Semen, the fluid that carries sperm out of the body, is not alive. The sperm are the tiny swimmers in the semen that can cause pregnancy, and they are indeed alive for awhile out side the man's body.
Yes, water also is in composition of sperm.
If you are male past the age of puberty, and stil alive, you have sperm.
no. because once it is exposed to air it will automatically die.
It prevents secondary fertilization by another sperm cell.
