      Human reproductive organs

      Lesson details

      Learning outcome

      I can identify the organs of the human male and female reproductive system and describe the roles of the parts.

      Key learning points

      1. The function of the male reproductive system is to produce sperm cells.
      2. Sperm cells are made and stored in the testes.
      3. Females are born with all their eggs inside their ovaries, each month an egg is released.
      4. The testes and the ovaries make hormones.
      5. The male and female reproductive systems must work together to produce offspring.

      Keywords

      • Testes - The testes (singular testis) produce sperm and male sex hormones.

      • Penis - The penis is a male sex organ used for sexual intercourse and to release urine.

      • Ovaries - The ovaries (plural ovary) contain and release egg cells, and release female sex hormones.

      • Uterus - The uterus is a muscular bag where the fetus develops before birth.

      • Vagina - The vagina is a muscular tube used for sexual intercourse and childbirth.

      Common misconception

      Male reproductive systems are bigger and more complex than females, that they are totally separate systems.

      Show female and male systems next to each other and how they work together as a unit to produce offspring.

      Teacher tip

      Focus on the role of the systems in reproduction only, explaining the role of the systems in producing offspring.
