  1. Chapter 5Gender Issues

  2. Sex and GenderDefinitions • Sex • genetic, anatomical • Gender • psychosocial meaning of maleness and femaleness • Gender Identity • subjective sense of being male or female • Gender (Sex) Role • cultural norms for male and female behavior

  3. Gender-Identity Formation • Typical prenatal differentiation • 23 human chromosomes • 22 autosomes and 1 sex chromosome • Chromosomal sex • XX: female XY: male • DSS gene on X • SRY gene on Y

  4. Typical Prenatal Differentiation

  5. Typical Prenatal Differentiation • Gonadal sex • Ovaries or testes • Hormonal sex • Estrogens and androgens

  6. Typical Prenatal Differentiation • Internal structures • Müllerian duct • Males – Vas deferens, seminal vesicles, ejaculatory duct • Wolffian duct • Females – Fallopian tubes, uterus, inner 1/3 vagina • External structures • Genital tubercle • Clitoris or penis • Labioscrotal swelling • Labia or scrotum

  7. Prenatal Differentiation of Internal Structures

  8. Prenatal Differentiation of External Genitals

  9. Homologous Sex Organs

  10. Sex Differentiation Of The Brain • Hypothalamus • Differentiates in pregnancy • Directs production of sex hormones • May influence sex differences and sexual functioning • Cerebral hemispheres • Corpus callosum

  11. Parts of the Brain

  12. Atypical Prenatal Differentiation • Intersexed • True hermaphrodites • Pseudohermaphrodites • Sex chromosome disorders • Turner’s syndrome XO • Klinefelter’s syndrome XXY

  13. Atypical Prenatal Differentiation • Disorders affecting prenatal hormonal processes • Androgen insensitivity syndrome (AIS) • Fetally androgenized females • DHT-deficient males

  14. Atypical Prenatal Differentiation

  15. Social Learning Influences on Gender Identity • Firm gender identity by age 3 • Mead study • Culture determines gender role • Long-term case studies by Money • Psychosexually neutral at birth • Follow-up of Money’s cases by Diamond • Another case often overlooked (Bradley) • Long-term problems with surgical reassignment

  16. The Interactional Model • Nature • Biological determinants • Nurture • Social learning and the environment • Acknowledge the interaction of both • Relative roles are still unclear

  17. Transsexualism and Transgenderism • Transexualism • Gender identity is opposite to biological sex • Transgendered • Appearance and/or behavior does not conform to traditional gender roles • Variations of transgendered behaviors • Intersexed people • Gender Identity vs. sexual orientation

  18. Transsexualism • Etiology • Options • Gender blending/cross-dressing • Psychotherapy • Sex reassignment • Outcomes

  19. Gender Roles • Gender-based stereotypes (North American) • Males • Independent and aggressive • Females • Dependent and submissive • Recent trend away from rigid stereotypes • Women less entrenched than men in rigid gender-role stereotypes • Ethnic variation in gender roles

  20. Gender RolesAgents of Socialization • Parental expectations • Peers • School teachers and textbooks • Television and gender-based stereotypes • Religious training

  21. Gender Role Expectations • Women undersexed, men oversexed • Men initiate, women receive • Women as controllers, men as movers • Men are unemotional and strong • Women are nurturing and supportive

  22. AndrogynyTranscending Gender Roles • Having characteristics of both sexes • Benefits • Drawbacks • May show more flexibility and comfort with sexuality

  23. Chapter 6Sexual Arousal and Response

  24. The Brain and Sexual Arousal • Cerebral cortex (mental events) • Reasoning, language, and imagination • Limbic system and sexual behavior • Hypothalamus • Neurotransmitters • Dopamine facilitates sexual arousal • Serotonin inhibits sexual arousal

  25. The Limbic System and Sexual Behavior

  26. The Senses and Sexual Arousal • All sensory systems can contribute to arousal • Touch is the dominant “sexual sense” • Primary erogenous zones • Secondary erogenous zones • Vision usually next in dominance • Visual stimuli • Men self-report higher arousal than women • Women and men have similar physiological responses

  27. Other Senses and Sexual Arousal • Smell may arouse or offend • Pheromones • Taste plays a minor role • Hearing plays a variable role

  28. Aphrodisiacs • Substances believed to arouse sexual desire or increase capacity for sexual activity • Food • Drugs and alcohol • Yohimbine • No clear evidence of genuine aphrodisiac qualities • Role of expectations

  29. Anaphrodisiacs • Inhibits sexual behavior • Drugs (e.g. opiates, tranquilizers) • Antihypertensives, antidepressants & antipsychotics • Birth control pills • Nicotine • Constricts blood flow • Possibly reduces circulating testosterone

  30. The Role of Hormones in Sexual Behavior • Steroid hormones • Androgens (including testosterone) • Produced by testes, adrenal glands, and ovaries • Estrogens • Produced by ovaries and testes • Women and men produce both types • Neuropeptide hormones • Oxytocin

  31. Sex Hormones in Male Sexual Behavior • Testosterone • Linked to sexual desire and genital sensitivity • Castration leads to reduced sexual desire • Antiandrogen drugs • Hypogonadism

  32. Sex Hormones in Female Sexual Behavior • Estrogens • Overall link between estrogen and female sexual behavior is unclear • Estrogen Therapy (ET) • Testosterone • Role as major libido hormone in females

  33. How Much Testosterone Is Necessary? • Two forms of testosterone (free and bound) • Free testosterone linked to libido • Although women have less free testosterone, their cells are more sensitive to it than men’s • Too much testosterone is linked to adverse effects • Testosterone levels decrease with age • Fairly rapid decrease for women at menopause; more gradual decline for men • Testosterone Replacement Therapy

  34. Oxytocin and Sexual Behavior • Secreted during cuddling and physical intimacy • Increased skin sensitivity • High levels associated with orgasmic release for women and men • For women, stimulates contractions of uterine wall during orgasm

  35. Sexual Response

  36. Sexual Response • Master’s and Johnson’s Four Phases • Excitement • Plateau • Orgasm • Resolution

  37. Sexual Response • Master’s and Johnson’s Four Phase Model • Phases of physiological responses • Two basic physiological processes • Vasocongestion • Myotonia

  38. Sexual Response Cycle

  39. Female Sexual Response

  40. Male Sexual Response

  41. Orgasm • Shortest phase of sexual response cycle • Men and women’s subjective descriptions of orgasm are similar • Most female orgasms result from stimulation of the clitoris • Grafenberg spot • Area on lower front wall of vagina • Sensitive to pressure • Sometimes results in “ejaculation”

  42. Sex Differences in Sexual Response • Greater variability in female response • Male refractory period • Women can experience multiple orgasms

  43. Aging & Sexual Response Cycle • Older women • Response cycle continues, but with decreased intensity • Excitement: • Vaginal lubrication begins more slowly, reduced amount • Plateau: • decreased vagina flexibility • Orgasm: • number of uterine contractions decrease • Resolution: • occurs more rapidly

  44. Aging and the Sexual Response Cycle • Older men • Response cycle continues, with changes in intensity and duration of response • Excitement: • lengthened time to erection • Plateau: • able to sustain plateau phase longer • Orgasm: • reduced muscular contractions and force of ejaculation • Resolution: • occurs more rapidly • refractory period lengthens

  45. Age-Related Changes in the Sexual Response Cycle

  46. Chapter 7Love and Communication in Intimate Relationships

  47. What Is Love? • Difficult to define and/or measure • Special attitude with behavioral and emotional components • Different things to different people • Difficult to measure

  48. Types of Love • Passionate Love • Also known as romantic love or infatuation • Intense psychological feelings • Generalized physiological arousal • Strong sexual desire • Avoid conflict • Feelings of completeness • Short-lived

  49. Types of Love • Companionate Love • Less intense than passionate love • Friendly affection and deep attachment • Familiarity and tolerance for short-comings • More enduring than passionate love

  50. Sternberg’s Triangular Theory of Love
