Study Notes

Male Reproductive System

The vas deferens is a coiled duct where sperm cells are stored after production.
Pregnancy duration is approximately 260 days, starting from fertilization to birth.
Semen is produced by the prostate gland and seminal vesicles, which nourish sperm cells.
Each ejaculation contains around 300 to 500 million sperm cells.
Sperm cells can survive up to 48 hours within the uterus.

Sexual Response Cycle

The sexual response cycle includes four phases: excitement, plateau, orgasm, and resolution.
The excitement phase marks the beginning of sexual arousal, with physiological changes like increased pulse and blood pressure.
The plateau phase involves further physical changes, such as heightened sensitivity in sexual organs and increased heart rate.
The orgasm phase involves muscle contractions and ejaculation in men, and potential multiple orgasms in women.
The resolution phase is where the body returns to its normal state post-orgasm.

Sexual Arousal

Sexual arousal is complex and can be triggered by stimulating erogenous zones, such as the genitals, mouth, and breasts.
Masturbation is a common form of sexual stimulation that is less influenced by the presence of a partner.
Sexual fantasies are significant to arousal; men typically report more fantasies and a higher frequency of sexual desire compared to women.

Components of Love

Robert Sternberg's theory identifies three components of love: intimacy, passion, and commitment.
Intimacy encompasses feelings of closeness and connection.
Passion includes romantic attraction and physical desire.
Commitment involves the decision to love and maintain that love, forming different types of romantic love based on these components.

Material Self and Identity

The material self represents identity through possessions, including body and clothing, which are influenced by peer groups, especially among adolescents.
Clothing choices symbolize social status and are seen as important identifiers.
Material possessions such as homes, cars, and pets are extensions of self-identity, reflecting social status and personal achievement.

Consumer Culture

Consumer culture emphasizes the importance of material possessions in defining identity and social status.
It involves a social arrangement reliant on the consumption of products, mediated through markets.
Russell Belk's work highlights that material possessions correlate with hard work and success, influencing how success is measured.
A consumerist society focuses on extensive spending and energy on acquiring more possessions, which drives individuals to seek higher achievements.
