sperm into the vagina and swim up the cervix into the fallopian tubes. when the sperm reach the egg they cluster around it and one of them gets through the egg membrane. the egg membrane changes to stop any more sperm getting in. the nucleus of the sperm fuses with the nucleus of the egg this is called fertillisation. the egg and sperm become a zygote and the zygote divides and becomes a ball of cells (morula). after 7 days the ball of cells reaches the uterus and implants itself into the lining which is called implantation.
