1 Psychology 320: Psychology of Gender and Sex Differences Lecture 3
2 Introduction 1.What is gender? (continued)
3 By the end of today’s class, you should be able to: 1. generate examples of intersexuality and gender variance. 2. discuss the causes, symptoms, and therapeutic options for Turner’s syndrome and Androgen Insensitivity syndrome. 3. describe third genders identified in other cultures.
4 Examples of intersexuality: What is gender? (continued)
5 Results from a missing or damaged X chromosome (XO) in females. Turner’s Syndrome Individuals with Turner’s syndrome develop female external genitalia, but do not develop functional ovaries. Incidence: 1/2500 – 1/5000 live births.
7 Symptoms: Short stature Webbed neck Lymphedema Shield shaped chest Widely-spaced nipples Low hairline Atypical ears Cubitus valgus Increased weight Reproductive sterility Amenorrhea Poor breast development Horseshoe kidney Visual impairments Cardiovascular malformations Spatial perception deficits
8 Webbed neck Shield-shaped chest Widespread nipples Atypical ears An Infant with Turner’s Syndrome
9 A Child with Turner’s Syndrome A = Webbed neck B = Cubitis valgus C = Lymphedema
12 Occurs among XY individuals whose cells are insensitive to androgens. Due to the presence of a Y chromosome, androgen- secreting testes develop in the fetus; however, the body does not respond to these androgens. Androgen Insensitivity Syndrome (AIS) As a result, external genitalia appear female. Prevalence: 1/13,000 – 1/65,000
13 Symptoms: Amenorrhea Reproductive sterility Undescended testes Shortened vagina Little or no body hair Tend to exceed societal standards of beauty for females.
14 Adults with AIS
15 Therapeutic options: Masculinizing hormones are ineffective; vaginoplasty may be performed. Most individuals with AIS report satisfaction with a female gender identity.
