• 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

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

• Vagina
A 3- to 5-inch long muscular tube that extends from the vulva to the cervix of the uterus.
• The “G Spot”

• 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

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
Copyright Atomic Dog Publishing, 2004
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
