Unit 3 - Adolescents - Part 1 Flashcards
What age does female puberty begin?
8-10 years. Female puberty onset is linked to weight, so the heavier she is the earlier the onset.
What is Gonadotropin-releasing hormone (GnRH)?
- A hormone released by the hypothalamus in both male and female puberty.
- GnRH acts on the anterior pituitary gland causing it to release Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
What does Follicle Stimulating Hormone (FSH) do in male puberty?
FSH regulates the function of the testes so that sperm production can begin
What does Luteinizing Hormone (LH) do in male puberty?
LH promotes testosterone production in the testes
What is Spermarche and when does it occur?
Spermarche (first ejactulation) typically occurs between the ages of 12 and 13
What is testosterone responsible for?
- Maturation of the sperm
Secondary sex characteristics and sex drive - This includes muscle growth,
- hair development,
- lowering of voice (growth of larynx)
- oil secretion (acne).
When do males enter puberty?
9-16 years
What does Follicle Stimulating Hormone (FSH) do in female puberty?
FSH and LH both target the ovaries. They both stimulate the developing follicles (eggs) to release estrogen.
What does Luteinizing Hormone (LH) do in female puberty?
LH stimulates the corpus luteum to secrete progesterone and some estrogen
What is estrogen?
Estrogen is responsible for the menstrual cycle, including ovulation, as well as secondary sex characteristics.
Secondary sex development in females includes
- distribution of fat
- development of breasts
- widening of hips
What is menrache?
- first menstrual period
- occurs between 10 and 17
- usually takes a year for the menstrual cycle to follow a pattern and for the female to be considered fertile
Why is mood affected during puberty?
- Shifting levels of hormones in the body, along with other changes are often responsible for this
- Adolescents respond differently to the rapid changes in their bodies. Often, they are self conscious
_______________________ - Typically, males who develop early are more confident and independent than other males.
- Females who develop early, tend to be more self conscious and embarrassed.
Sex vs Gender?
- Sex is assigned based on appearance of a person’s external anatomy at birth (penis or vagina)
- Gender is an identity that the person senses internally - non-biological
What is intersex?
- People who are intersex have genitals, chromosomes or reproductive organs that don’t fit into a male/female sex binary.
- Their genitals might not match their reproductive organs, or they may have traits of both.
- Being intersex may be evident at birth, childhood, later in adulthood or never.
What are gender roles?
- The pattern of masculine or feminine behaviour of an individual that is
defined by a particular culture and that is largely determined by a person’s upbringing - Gender roles give meaning to sexual gendered identity
What are gender stereotypes?
- Gender Stereotypes: an oversimplified or distorted generalization about the characteristics of men and women
- When gender roles become so rigid and engrained they become stereotypes
- Ex. Pink for girls, blue for boys. Kitchen toys for girls, car toys for boys.
What is gender intensification hypothesis?
- Idea that pressures to behave in sex-appropriate ways intensify during adolescence
- The intensification is believed to be temporary and more influential for females
- This could result from social pressure
