1. Physical Development

2. Identify the important parts of the male and female reproductive system

3. Female Sexual System Bartholin’s Gland Cervix Clitoris Fallopian Tubes
Fimbriae Hymen
Labia majora Labia Minora
Ova Ovaries
Pituitary gland Ureter
Urethra Uterus
Vulva Mons Pubis (mons veneris)

4. Male Sexual System Cowper’s glands Epidydmis Foreskin Glans Penis
Pituitary Gland Prostate
glands Scrotum
Testes Ureter
Urethra Vas deferens

5. Pubertal Myths Puberty starts at one point in time
Puberty Strikes without warning
Puberty is the result of raging hormones

6. Endocrine System regulated by endocrine glands
pituitary is the master, secretes gonadotropins
around age 7, LH and FSH release in sleep occurs
LH stimulates testosterone production that causes genital growth, body hair, and change of voice (in males).
FSH stimulates testicle growth and sperm production
Lh= lutenizing hormone
FSH= follicle-stimulating hormone

7. Females store LH in early adolescence
FSH makes ovaries release hormone resulting in breast development, increased body hair and menstruation.

8. Genetic Influences Most changes in puberty caused by genetics.
Genes have most influence on rate of growth and weight.
Body hair and menarche also genetic based

9. Nutrition
Secular trend: a steady drop in the average age of menarche over the last 100 years, may be leveling off.
Poor nutrition can delay or suppress menstruation

10. Sequence of Male Pubertal Change
Testicular enlargement
change in texture and color of scrotum
Increased growth of penis (about 12.5 years)
Growth of pubic hair
growth spurt of height
First ejaculation (semenarche)
Seminal fluid is infertile at this time
Growth of axillary hair

11. Growth of facial hair
Breaking of voice
Breast changes
differentiate from gynecomastia
More penile growth, prostate growth and seminal vesicles
Hair growth from pubic area to naval
Start of recession of hairline

12. Sequence of Female Pubertal Change
Growth spurt: height, weight, fat on hips
Growth of breasts, includes some enlargement of areola
Growth of vagina and change of pH balance
Growth of pubic hair, approximately 6 months after breast buds develop
Continued growth of breasts and pubic hair

13. Growth of uterus
Enlargement of ovaries
Menarche, simultaneous with rapid decline in height growth spurt
Fertility: months after menarche

14. male issues penis size (performance) unwanted erections (unruly penis)
nocturnal emissions (wet dreams)
ejaculation (masturbation)
body size, strength (steroids)

15. male issues voice changes, mannerisms estrogenic onset (gynecomastia)
“success objects” - success enhances desirability
always horny, always ready
desire for contact comfort (love) disguised as sex

16. Female Issues female issues
breast, buttocks, thighs, legs (size, shape)
menstruation (“the curse”)
genital hygiene
“attractiveness” (face, general body)
fear of fat (80% diet, eating disorders)

17. female issues androgenic onset (hairy, acne) “sex objects”;
eager, knowing but not too willing
success is unattractive; down play success
desire for sex disguised as contact comfort (love)

18. Contrast of male and female changes
Growth spurt in girls begins on average 2 years earlier
No event in male development is directly comparable to menarche (?)
Genital development is somewhat earlier in girls than boys
Tanner’s Sexual Maturity Scale identified development in various areas

19. Timing and Puberty Normal range is very broad
The individual’s perception of normality is more influential than objective measures
Maturity of appearance effects how adolescents are treated
Early maturing is positive for males, and may be negative for females
Late maturing is difficult for both boys and girls- but long term may be associated with positive outcomes.

20. Body Image
Self-concept and self-esteem are tied to how we believe others see us
Adolescents are generally critical of their own appearance
Girls are far more likely to suffer from poor body image
Males are more focused on appearing strong
