    Study Notes

    Primary Sex Characteristics

    • Develop in the embryo
    • Directly involved in reproduction
    • Females develop ovaries, uterus, cervix and vagina.
    • Males develop testes, penis, scrotum and prostate glands

    Secondary Sex Characteristics

    • Develop during puberty
    • Not directly involved in reproduction
    • These are the visible physical changes that differentiate males and females
    • They are influenced by hormones

    Stages of the Human Sexual Response

    • Excitement phase
      • Increased heart rate and breathing
      • Muscle tension
      • Genital swelling
      • Vaginal lubrication in females
      • Testicular swelling in males
    • Plateau phase
      • Intensified arousal
      • Clitoral sensitivity/retraction in females
      • Muscle spasms in both genders
      • Testicles retract in males
      • Increased cardiovascular response
    • Orgasm phase
      • Involuntary muscle contractions
      • Peak heart rate and breathing
      • Release of sexual tension
      • Ejaculation in males
      • Vaginal or uterine contractions in females
      • Feelings of pleasure
    • Resolution phase
      • Return to normal body state
      • Sense of well-being
      • Fatigue
      • Refractory period (men)
      • Multiple orgasms are possible (women)

    Brain and Sexual Behavior

    • Cerebral cortex: Controls sexual thoughts and fantasies
    • Hypothalamus: Controls sexual function and hormone secretion
    • Limbic system: Controls emotions and feelings
    • Pituitary gland: Secretes hormones

    Hormones & Sexual Behavior

    • Oxytocin: "Love hormone" released during orgasm, promotes closeness and bonding
    • FSH (Follicle-Stimulating Hormone): Triggers ovulation, peaks during fertility
    • LH (Luteinizing Hormone): Regulates testosterone production, a key driver of male motivation
    • Vasopressin: Boosts male arousal, enhances sexual motivation
    • Estrogen: Regulates female sexual desire
    • Progesterone: Regulates female sexual desire

    Types of Love

    • Lust: Erotic passion, driven by testosterone in men and estrogen in women
    • Attraction: Romantic passion, characterized by a craving for the partner's presence, excitement, and shared experiences
    • Attachment: Commitment, desire for a lasting bond, commitment to building a family

    Additional Notes

    • SRY gene triggers male development
    • Without the SRY gene, the body will develop as female
    • The brain controls sexual responses, emotions, and hormonal release
    • Erogenous zones are sensitive areas of the body that enhance sexual pleasure
    • Puberty is a period of rapid changes, development of reproductive and secondary traits
