Adolescence begins with puberty between ages 9-14 when a burst of hormones activates testes maturation. The testes, located in the scrotum, produce sperm through spermatogenesis and male sex hormones. Sperm travel through the epididymis, vas deferens, and urethra, mixing with secretions from accessory glands to form semen, which is ejaculated through the penis.General anatomy of the male reproductive system

The male reproductive system produces and transports sperm. During puberty, the testes enlarge and begin producing testosterone and sperm through spermatogenesis within the seminiferous tubules. Mature sperm pass through the epididymis, vas deferens, and urethra to be ejaculated with fluids from the seminal vesicles, prostate, and bulbourethral glands. The penis becomes erect through increased blood flow, allowing for sexual intercourse and delivery of sperm.The male reproductive system

The male reproductive system consists of both internal and external organs. The external organs include the testicles, which produce sperm and testosterone, and the penis. The internal organs include the vas deferens, which carry sperm from the epididymis to the urethra, the seminal vesicles, which secrete fluid to nourish sperm, and the prostate gland, which produces fluid to activate sperm. During ejaculation, muscles contract to push sperm and fluids through the urethra.MALE REPRODUCTIVE SYSTEM

The male reproductive system consists of both primary and secondary organs. The primary organs are the testes, which produce sperm and the hormone testosterone. Secondary organs include ducts like the epididymis and vas deferens that transport sperm, as well as accessory glands like the seminal vesicles and prostate gland that provide fluids to nourish and protect sperm. The external genitalia are the penis and scrotum. The primary roles of the male reproductive system are production and transportation of sperm and depositing sperm in the female reproductive tract during sexual intercourse.Male reproductive system

The male reproductive system undergoes significant changes during puberty due to increased hormone production. This causes enlargement of the testes and genitals. Sperm are produced in the testes through spermatogenesis, a process where diploid cells undergo meiosis to become haploid sperm. Mature sperm are stored in the epididymis and travel through ducts to be ejaculated through the urethra.Male reproductive system

The male reproductive system undergoes significant changes during adolescence due to a burst of hormones that activate the maturation of the testes and lead to physical changes like growth of the genitals and body hair. Sperm production begins in the seminiferous tubules of the testes where spermatogonia undergo mitosis and meiosis to form haploid spermatids and eventually mature sperm. The sperm travel through the epididymis, vas deferens, and urethra where secretions from accessory glands form semen. During ejaculation, sperm are propelled from the body through the urethra by contractions of the penis.Male reproductive system

The major components of the male reproductive system are the testes, epididymis, ductus deferens, and ejaculatory duct on each side. The scrotum contains the testes and is divided into two compartments. The testes develop in the abdomen and descend into the scrotum before birth. Within the testes are seminiferous tubules that produce sperm. The epididymis is a coiled duct that courses along the testes where sperm mature. Blood flows into the testes via the testicular artery and drains via the testicular veins. The penis contains three cylinders of erectile tissue and transmits semen and urine.Male reproductive system

The male reproductive system has the sole function of producing sperm and delivering it to females. The testes produce sperm through spermatogenesis within seminiferous tubules. Mature sperm travel through the epididymis, vas deferens, seminal vesicles, prostate gland, and urethra, where they mix with fluids before being ejaculated via the penis. The process takes about 74 days and requires a temperature slightly below normal body heat.Male reproductive system anatomy

2. Gametes have half the number of chromosomes (haploid) compared to normal body cells (diploid) to ensure the new individual formed after fertilization has the full chromosome number.
3. The male reproductive system includes testes, sperm ducts, penis and glands that produce semen. The female system includes ovaries, oviducts, uterus and vagina. Both systems undergo changes during puberty to become reproductively mature.Reproduction.pptx

1. To produce gametes (sperm and eggs) through processes like spermatogenesis and oogenesis
2. To support the development of offspring through gestation and birth
3. To ensure genetic variation between parents and offspring through meiosis and sexual reproduction
The male reproductive system includes testes, which produce sperm and hormones, and organs like the penis and vas deferens that work together to deliver sperm to the female reproductive tract during intercourse. The female reproductive system includes ovaries, which produce eggs, and a uterus that supports pregnancy and childbirth.

This chapter discusses sexually explicit materials, prostitution, and sex laws in the United States. It notes that the US sex industry is worth billions annually and views on sexually explicit content vary widely. Pornography is depicted negatively while erotica is seen positively. Prostitution involves the exchange of sex for money or goods, and those in prostitution often face abuse and health risks like HIV. Laws around obscenity, child protection, and prostitution are debated as views on sexuality and what is considered "victimless" vary greatly within societies and cultures.strong6_ppt_ch16

HIV/AIDS is caused by the human immunodeficiency virus (HIV) which weakens the immune system and allows opportunistic infections. It was first observed in the 1980s and has since caused over 25 million deaths globally, with about 40 million people currently living with HIV. The virus is transmitted through sexual contact, sharing needles, or from mother to child during birth or breastfeeding. While treatment can suppress HIV and reduce transmission, prevention through testing and safe practices is the best way to end the pandemic.strong6_ppt_ch15

Sexual expression involves behaviors and feelings related to revealing one's sexuality. While youthfulness and health are universally considered attractive traits, attractiveness standards vary across cultures. Sexual scripts organize our expressions and have cultural, intrapersonal, and interpersonal components. Autoeroticism includes solitary sexual activities like fantasizing, masturbating, and erotic dreams. Sexual behaviors with others range from non-genital touching and kissing to oral-genital contact, intercourse, and anal eroticism.strong6_ppt_ch08

Sexuality changes across adulthood. In early adulthood, people establish their sexual orientation and identity, develop intimate relationships, and make choices around fertility. In middle adulthood, marital sexuality may decrease in frequency over time while dating and cohabitation become more common for singles and divorced individuals. In late adulthood, biological changes can impact sexuality but emotional and relational aspects remain important, and many still find sexual activity and satisfaction regardless of age.strong6_ppt_ch06

Gender and gender roles can be complex topics with biological, social, and cultural components. Biologically, sex is determined by genetic or anatomical characteristics, while gender refers to social and cultural roles associated with being male or female. Gender identity develops from a combination of biological and environmental factors. Traditional Western views emphasized polar masculine and feminine traits and roles, but modern perspectives recognize more fluidity and diversity in gender expressions. Conditions like intersexuality or transgenderism also show that biological sex and gender identity do not always align.strong6_ppt_ch03

- 2. Male Sex Organs: What Are They for? Sex organs serve a reproductive function Also serve other functions: Bringing pleasure to self Giving pleasure to others May serve to attract potential sexual partners Sharing of genital sexuality can play a bonding role in relationships
- 3. External Structures The penis The scrotum
- 4. The Penis Penis: from Latin word for tail organ through which sperm and urine pass Three main sections: Root: attaches penis within the pelvic cavity Shaft: contains 3 parallel columns of erectile tissue Corpora cavernosa: 2 columns along the front surface Corpus spongiosum: runs beneath corpora cavernosa, also forms the glans
- 5. The Penis Glans penis: head of penis; most sensitive Corona: rim at base of the glans Frenulum: on underside of penis; triangle of sensitive skin Foreskin: sleeve-like covering of the glans Circumcision Urethra : a tube that transports urine and semen When penis erect, urinary duct is blocked
- 6. The Penis: Myths Penis size not linked to body size or weight, muscular structure, race or ethnicity or sexual orientation No relationship between penis size and ability to have sexual intercourse or satisfy a partner
- 7. The Scrotum A pouch of skin that holds the two testicles Scrotum skin more heavily pigmented Sparsely covered with hair Divided in the middle by a ridge of skin Testicle temperature control: 93 属F
- 8. Internal Structures Testes: Two major functions: sperm and hormone production Shaped like olives; 1.5 long and 1 diameter. Size and weight decrease as men age Not usually symmetrical in the way they hang Suspended by spermatic cord Within each testicle, there are about 1000 Seminiferous tubules: Production of sperm takes place in these tubes
- 9. Internal Structures Epididymis C shaped structure on the back of the teste Sperm mature in vas deferens Vas Deferens The ducts that carry sperm from testicles to urethra for ejaculation Vas deferens joins the ejaculatory duct within prostate gland
- 10. Internal Structures Seminal vesicles Secrete fluid that makes up 60% of semen Prostate gland Secretes fluid that makes up 30-35% of semen Can be stimulated in anal play Cowpers (bulbourethral) glands Secrete thick clear mucus prior to ejaculation Urethra

- 12. Male Sexual Physiology Production of hormones Spermatogenesis
- 13. Male Reproductive Hormones Testosterone Acts on seminiferous tubules to produce sperm Regulates sex drive Is responsible for development of secondary sex characteristics in puberty Influences growth of bones and muscle mass
- 14. Spermatogenesis Ongoing process from puberty onward Sperm produced within seminiferous tubules of testicles (64-72 days) Several 100 million sperm produced daily 20 days for sperm to travel through epididymis During this time they become fertile and motile Upon ejaculation, sperm expelled through urethra by muscular contractions
- 15. Male Sexual Response Erection Blood vessels expand and increase blood in penis Veins that normally carry blood out are compressed, leading to engorgement of penis Secretions from Cowpers glands appear at tip
- 16. Ejaculation and Orgasm Emission stage Sperm sent into vas deferens Rhythmic contractions begin Feeling of ejaculatory inevitability Expulsion stage Rapid contractions Semen spurts from urethral opening Orgasm Intensely pleasurable physical sensations that usually accompany ejaculation Followed by refractory period
