Changes in Adolescence

• The teen years are a time of rapid changes.
• Puberty is the stage of growth and development
  when the body becomes capable of producing
  offspring.

  physical, mental/emotional, and social changes
  occur. Changes take place at all stages of the
  life cycle, beginning at birth.

5
Changes in Adolescence

• Many of the changes during adolescence are
  brought about by hormones, chemical substances
  produced in certain glands that help to regulate
  the way your body functions.
• Hormones are produced by the glands of the
  endocrine system.

6
The Endocrine System (contd.)
7
Changes in Adolescence

• In females, estrogen is a hormone produced by the
  ovaries that stimulates the development of female
  secondary sex characteristics
• In males, testosterone is a hormone produced by
  the testes that stimulates the development of
  male secondary sex characteristics

8
Changes in Adolescence

• Emotional changes
• As hormone levels change, teenagers may
  experience sudden mood changes
• Strong attraction for another person

9
Physical Changes in Adolescence

• Boys and girls mature and grow at different rates
  and at different ages during puberty..

  of 12 to 15.

10
Physical Changes in Adolescence

12
The Reproductive System

• The Reproductive System consists of the organs in
  the in the body involved in producing offspring.
• Female
• external organs (the vulva)
• Internal organs ovaries, fallopian tube, uterus
• Male
• External organ penis, scrotum
• Internal organs testes, vas deferens, seminal
  vesicles, Cowpers glands, prostrate gland

13
The Female Reproductive System

• Ovaries are the female reproductive glands that
  produce ova and estrogen.
• Ovulation is the release of a mature ovum from
  the ovaries. (generally monthly during a regular
  menstrual cycle).
• If fertilization occurs, it generally occurs in
  the Fallopian tube.
• The uterus is a muscular organ that receives and
  supports the fertilized ovum during pregnancy and
  contracts during childbirth to help with delivery.

14
The Female Reproductive System

• The Menstrual Cycle
• The menstrual cycle generally occurs over 28
  days. This means that a female will menstruate or
  have her period approximately every 28 days.
  However, many teens have irregular cycles and the
  length of their menstrual cycle varies.
• Menstruation last approximately 5 days. However,
  this too may vary.

16
The Male Reproductive System

• Sperm are produced in the testes and are the male

• Semen is the fluid that is released by the
  reproductive tract. Semen contains sperm and
  fluids from the seminal vesicles, prostrate
  gland, and Cowpers glands.
• (See pages 236-37 for additional information)

18
Conception

• Conception or fertilization is the union of an
  ovum and a sperm
• In the female body, one ovum matures and is
  released from the ovary each month.
• As the ovum moves through the Fallopian tube, it
  can be fertilized if sperm are present
• After conception, a fertilized ovum grows
  (divides) and moves through the Fallopian tube.
• This cluster of cells attaches to the lining of
  the uterus and continues to grow.
• A developing baby through the second month of
  growth after conception is called an embryo .
• A developing baby from the 9th week to birth is
  called a fetus.
