Puberty

  1. 1. Created by: Brenda Yubi and Valeria Quinn
  2. 2. What is puberty?  Puberty is the period in children's lives when they experience physical changes by which their bodies eventually become adult bodies that are capable of reproducing.
  3. 3. What is the difference between male and female puberty?  Girls start puberty about one to two years earlier than boys.  Girls generally complete puberty in a shorter time than boys.  Girls reach adult height and reproductive maturity approximately 4 years after the physical changes of puberty appear.  Boys continue to grow for about 6 years after the first visible changes of puberty.  A girl's puberty general spans from the ages of 9 to 14.  A boy's puberty generally spans from the ages of 10 to 17. Experts say this longer span is probably why adult males are generally taller than adult females.
  4. 4. What happens during a girl's puberty?  Sexual organs - the girl's clitoris (a small and sensitive part of the female genitals which is part of the vulva) and the uterus (womb) will grow.  Menstruation begins - one of the first things that happens during a girl's puberty is the start of her monthly menstrual cycle. When periods start it means that the girl is becoming a woman and she can become pregnant.  Breast changes - the girl's breast will start to grow. A small and sometimes painful lump may be felt just below the nipple when her breasts start to develop - this is normal.  Vaginal discharge - vaginal discharge may start or change  Body hair - hair will begin to grow in her pubic area - firstly along the labia (the lips that are part of the external female sexual organs, known as the vulva), and then under her arms and on her legs.
  5. 5. What happens during a boy's puberty?  Scrotum, testicles and penis - the boy's scrotum will begin to thin and redden and his testicles will grow. Later, usually around the age of 13 (this can vary) his penis will grow and lengthen while the testicles will continue to grow.  Voice change - as the voice box (larynx) gets bigger and the muscles or vocal cords grow, the boy's voice will "break" or "crack". This is normal. Eventually the boy's voice will become deeper.  Wet dreams - boys may ejaculate during their sleep and wake up in the morning with damp sheets and pajamas. This does not mean the boy was having a sexual dream. It is important that his loved ones explain to him that they understand that he cannot prevent them from happening. Wet dreams are just part of growing up.  Involuntary erections - during puberty boys will have spontaneous erections. These will occur without the penis being touched and without sexual thoughts triggering them. These may be embarrassing if they happen in public. This is a natural part of growing up.
  6. 6. What causes puberty?  Genes - experts say that puberty starts with a single gene called KiSS1. This gene is present in our bodies at birth and produces another gene called GPR54. GPR54 lies dormant in the body for many years until kisspeptin - chemicals produced by the KiSS1 gene - activate it. Activated GPR54 stimulates the brain to produce GnRH (gonadotropin-releasing hormone) - a powerful hormone. GnRH causes other glands in the body, such as the testes in boys and ovaries in girls to release other hormones.  Hormones - the testes produce testosterone which encourages the development of the testicles and penis, muscle growth, hair growth, and the deepening of the male voice. The female ovaries also produce testosterone, in much smaller amounts - and it is used to help maintain muscle mass and bone strength. The ovaries produce estradiol which stimulates breast growth, the female reproductive system, as well as regulating the monthly menstrual cycle.
  7. 7. Neurohormonal process The endocrine reproductive system consists of the hypothalamus, the pituitary, the gonads, and the adrenal glands, with input and regulation from many other body systems. True puberty is often termed "central puberty" because it begins as a process of the central nervous system. A simple description of hormonal puberty is as follows:  The brain's hypothalamus begins to release pulses of GnRH.  Cells in the anterior pituitary respond by secreting LH and FSH into the circulation.  The ovaries or testes respond to the rising amounts of LH and FSH by growing and beginning to produce estradiol and testosterone.
  8. 8. Taking care of your body!!
  9. 9. Shower Adolescents during puberty may want to start taking a daily shower or bath if they don`t already. This can keep the body clean and reduce the smell from the sweat.
  10. 10. Deodorant and antiperspirants  The change with hormones will cause adolescents to sweat more and for sweat to have a stroger odor. Daily baths and showers help with the smell as well as deodorants and antiperspirants.
  11. 11. Hair Your hair may be more oily than it used to. Washing it more often can help mantain less oily.
  12. 12. Skin  With the increase of oil on the skin it is important to wash your face twice a day with a facial soap can help keep things under control.
  13. 13. Teeth/Dental Brush and floss twice a day to mantain good health.
