The glans (the rounded head of the penis) is a highly sensitive, important component in
sexual arousal
Circumcision, the surgical removal of the foreskin of the penis, occurs in approximately
9% of newborn males in Canada
Circumcision
Some suggest that the procedure promotes cleanliness and reduces the risk of urinary
tract infections in newborns and the risk of STIs in later life
Opponents of circumcision state that it is an unnecessary surgical procedure that causes
pain and puts the baby at risk for complications
Hormones and the Reproductive Life Cycle
Testes create androgens; testosterone
Ovaries create estrogens and progestins; progesterone
Adrenal glands produce androgens in males and females
Pituitary gland regulates hormones of testes, ovaries, and adrenal glands
Hypothalamus controls hormones of the pituitary gland
Differentiation of the Embryo
Sex chromosomes (X and Y) determine an individuals biological sex at the time of
conception
Genetic sex dictates whether the undifferentiated gonads become ovaries or testes.
Female Sexual Maturation
Puberty is the period of biological maturation during adolescence
Progesterone induces the development of female secondary sex characteristics during
puberty, regulates menstrual cycle, and sustains pregnancy
Female Sexual Maturation
Physical changes include breast development, rounding of the hips & buttocks
The beginning of the menstrual cycle, or menarche, is a major landmark of puberty
Menstrual Problems
Dysmenorrhea is painful or problematic menstruation
Premenstrual tension, premenstrual syndrome (PMS), & premenstrual dysphoric
disorder (PMDD) all vary in severity of symptoms, appear before the onset of menses
and disappear within a few days after the start of menstruation
Menstrual Problems
Strategies to provide relief:
Limit salt intake
Exercise
Don’t use alcohol or tobacco
Eat a nutritious diet
Relax
Male Sexual Maturation
Testicular growth is the first obvious sign
