    Study Notes

    Sexual Development

    • Sexual development in the embryo and fetus is determined by the sperm's chromosome.
    • A sperm carrying an X chromosome will result in female development (ovaries).
    • A sperm carrying a Y chromosome will result in male development (testes).
    • Puberty is a period of rapid physical and sexual development. It begins at different ages for boys and girls.
