Fusion of a female and male gamete (both haploid) to form a diploid zygote, which develops into a new individual.
Process of conception in which the sperm penetrates the egg (ovum).
The process that starts when a sperm contacts an ovum. It ends with the intermingling of chromosomes from both the sperm and ovum to produce a full set of chromosomes - 46 in most humans. The result is a zygote, often popularly referred to as a "fertilized ovum." If it has two X chromosomes, then the zygote is a female; if it has an X and Y, it is male. This is generally regarded as the start of pregnancy within the pro-life movement. Physicians and the pro-choice movement regard the start of pregnancy when the fertilized ovum attaches itself to the wall of the uterus.
