    ◦    Shaft: Body of the clitoris.

    ◦    Clitoral Hood: Skin covering the clitoris.

    ◦    Cavernous Bodies: Erectile tissue that swells during arousal.

    •    Vestibular Bulbs: Erectile tissue around the vaginal opening, aiding in lubrication and swelling.

    •    Bartholin’s Glands: Glands that secrete mucus for lubrication.

    •    Vestibule: Area between the labia minora, contains urethra and vaginal openings.

    •    Perineum: Area between the vulva and anus, involved in childbirth.

Female Internal Organs:

    •    Vagina: Muscular canal, serves as birth canal and menstrual passage.

    •    Hymen: Thin membrane at vaginal opening, not a reliable virginity indicator.

    •    Spongy Body: Surrounds urethra, contributes to erection.

    •    Urethra: Carries urine and semen out of the body.

    •    Testes: Produce sperm and testosterone.

Male Internal Structures:

    •    Epididymis: Tube where sperm mature and are stored.

    •    Vas Deferens: Tubes carrying sperm to the ejaculatory ducts.

    •    Seminal Vesicles: Produce fluid rich in fructose for sperm energy.

    •    Prostate Gland: Produces fluid for semen.

    •    Cowper’s Glands: Secrete pre-ejaculatory fluid for lubrication.

Sexual Response Cycle:

    •    Masters & Johnson: Excitement, Plateau, Orgasm, and Resolution.

    •    Kaplan’s Model: Adds Desire phase.

    •    Basson’s Model: Focuses on Intimacy and long-term relationships.

Prenatal Sexual Differentiation:

    •    Chromosomes: XX (female) or XY (male).

    •    Gonads: Develop into ovaries (XX) or testes (XY).

    •    Ducts: Wolffian (male) and Müllerian (female) ducts.

    •    Hormones: Testosterone for male development, absence for female.

    •    External Genitalia: Develop from genital tubercle, influenced by hormones.

    •    The clitoris is the main pleasure center for women.

    •    Vagina serves as both birth canal and menstrual passage.

    •    Prostate enlargement is common with age.

    •    Endometriosis involves abnormal endometrial tissue growth.

    •    Vasectomy is a sterilization procedure involving cutting the vas deferens.
