@dr_uu0: The journey of sperm begins after ejaculation, when millions of sperm cells enter the female reproductive system. They travel through the vagina, pass the cervix, and swim into the uterus. Only a few survive the long, challenging path to the fallopian tubes, where an egg may be waiting. One sperm successfully penetrates the egg, leading to fertilization and the start of a new life.#3danimation #Science #anatomy
