The sperm usually meets the egg in the upper part of the fallopian tube.
Progesterone keeps the endometrium thick and ready for implantation.
A sharp rise in LH around the middle of the cycle makes the mature follicle release the egg.
Sperm are made in the coiled seminiferous tubules of the testes.
Meiosis I and II give four haploid cells, and each becomes a sperm.
Divisions of an oocyte are uneven. Only one large egg forms and the other cells are small polar bodies.
In flowering plants one sperm fertilises the egg and the other joins the central cell.
A sperm nucleus fuses with the two polar nuclei, giving a triploid endosperm tissue that feeds the embryo.
Human chorionic gonadotropin (hCG) is made by the developing placenta and appears in the urine of pregnant women.
