Fertilization is defined as the process of union of two germ cells, egg and sperm, whereby the somatic chromosome number is restored and the development of a new individual exhibiting characteristics of the species is initiated.
During intercourse, when sperm leave the penis, they don't head straight to the uterus. In this course, some sperm attach to oviduct epithelial cells in the fallopian tubes or get stored in tiny chambers called crypts until fertilization primetime: ovulation.
