semen and the ovum are not human life. Not until the egg/ovum become fertilized and attach itself to the uterus wall. That's when life begins. Everything before that is not life but actions that flush the system to prepare the equipment /tools . It's maintenance for the reproductive system, to keep it in good running condition for when the zygote is formed. This cartoon would appeal to adult children who still giggle at the words penis and vagina.
