Topic 3 – Anatomy

Outline

 

 

Topic 4

Initial arousal

Brain:

Kaplan’s three-stage model (1979)

 

Masters and Johnson’s four-phase model

 

 

  1. Excitement phase (min-hour)
    1. Myotonia, vasoconstriction, increase in heart rate (HR) & blood pressure (BP)
    2. Sex flush
    3. M – erection
    4. F – vaginal lubrication, genital swilling
  2. Plateau phase (minutes)
    1. Increases in vasocongestion, myotonia, heart rate, & BP
    2. F- orgasmic platform swells (female)
    3. Rapid breathing & heart rate, BP increases
  3. Orgasmic phase (seconds
    1. Muscle spasms, BP & HR peak
    2. M – 1st stage emission (contractions push seminal fluid into urethral bulb), 2nd stage is expulsions, ejaculation
    3. F – 3 to 15 contractions of pelvic & vaginal muscles (uterus & anal sphincter contract rhythmically
    4. The complexity of female orgasm
      1. Freud (1905) Three Essays on the Theory of Sexuality
        1. Two-orgasm theory (clitoral, vaginal)
      2. Singer & Singer (1978) – Vulval, Uterine, Blended
  4. Resolution Phase (min to hours)
    1. Body gradually returns to its pre-aroused state
    2. Takes longer w/o orgasm
    3. Blood released from engorged areas, myotonia, dissipates and BP, HR, & respirations return
    4. M- following an orgasm, not responsive to stimulation (varies)
    5. F- multiple orgasms possible
