Chapter ThreeFemale Anatomy, Physiology, and Sexual Response


Female External Anatomy and Physiology - 1

• External Female Genitalia



• Vulva

The external female genitalia

• Mons Veneris

The soft cushion of fatty tissue that lies over the pubic symphysis (joint between the left and right pubic bones)



• Labia Labia Majora

Two elongated folds of fatty tissue that extend from the mons veneris to the perineum

Perineum

The area of skin between the opening of the vagina and the anus

Labia Minora

Two smaller elongated folds of fatty tissue that enfold the urethral and vaginal openings



• Anatomy of the Clitoris



• Clitoris

Sensory organ located at the top of the labia minora of the female genitalia

• Vaginal Opening Vestibule

The smooth tissue surrounding a woman’s urethral opening Introitus

The vaginal opening

• Urethral Opening Urethra

Short tube that connects the bladder with the urethral opening



• Internal and External Anatomy of the Female Breast



• Breast Self-Exam



• The Female Breasts

The female breasts are designed to provide milk for infants and young children.

• Personal Choices: Breast Self-Examination and Mammogram

Breast cancer is the most common cancer in women.

Most breast lumps are discovered by women themselves.


Female Internal Anatomy and Physiology - 1

• Female Reproductive Anatomy



• Vagina

A 3- to 5-inch long muscular tube that extends from the vulva to the cervix of the uterus.

• The “G Spot”

An alleged highly sensitive area on the front wall of the vagina 1 to 2 inches into the vaginal canal.

• Uterus

The womb; a hollow, muscular organ in which a fertilized egg may implant and develop.



• Personal Choices: Pap Smear Test and Pelvic Exam

Pap smear test: Procedure in which surface cells are scraped from the vaginal walls and cervix and examined under a microscope to detect the presence of cancer.

• Fallopian Tubes

Tubes that transport the ovum from an ovary to the uterus.



• Ovaries

Female gonads that produce 1) ova and 2) estrogen and progesterone.

• Menstruation/Menses: The sloughing off of blood, mucus, and lining of the uterus.

Menarche: First menstruation

• Menstrual Suppression: The use of hormones to suppress menstruation for therapeutic reasons


Problems of the Menstrual Cycle

• Oligomenorrhea: Irregular cycles

• Amenorrhea: Absence of menstruation for 3 or more months

• Dysmenorrhea: Painful menstruation

• Premenstrual syndrome: Physical and psychological symptoms caused by hormonal from ovulation to menstruation

• Premenstrual dysphoric disorder: Proposed diagnosis indicating severe PMS


Models of Sexual Response - 1

• Masters and Johnson’s Four-Stage Model of Sexual Response Excitement Plateau Orgasm Resolution

• Helen Kaplan’s Three-Stage Model of Sexual Response Desire Excitement Orgasm


Models of Sexual Response - 2

• Basson’s Contemporary Model of Sexual Response

Emphasizes that psychological factors, as well as biological factors, affect the processing of sexual stimuli

• Personal Choices: Engaging in Sexual Behavior When Desire Is Low

It is not unusual when one partner wants to engage in sex and the other does not.

As many as 30 to 40% of women in nonclinical samples report that they have low sexual desire.


Hormones and Sexual Response - 1

• Endocrine System


Hormones and Sexual Response - 2

• Hormone

Chemical messenger that travels from cell to cell via the bloodstream.

The reproductive hormones (estrogens, progesterone, and androgens) are mainly produced in the gonads.

The reproductive hormones influence reproductive development through organizing and activating effects.


Pheromones, Aphrodisiacs, and Sexual Response

• Pheromones

Chemicals secreted by an animal (or person) that influence the behavior or development of others of that species.

• Aphrodisiac

Any food, drink, drug, scent, or device that arouses and increases sexual desire.

Damiana: Primary agent identified as a sexual stimulant for women
