Reproductive System, part 1 – Female Reproductive System: Crash Course A&P #40

Human reproduction is complicated an important, and it’s going to take a four part series for us to cover it. Today, we’re kicking that off with the female reproductive system, starting with how sex hormones affect oogenesis and ovulation, continuing through how the ovarian and menstrual cycles mature and release oocytes, and create a comfy uterine environment for a fertilized egg.

    genitalia surgically altered (circumcised) and not in it’s NATURAL form?
