CHAPTER II: LESSON 2 PHYSICAL AND SEXUAL SELF  OBJECTIVES ◼ Discuss the developmental aspect of the reproductive system ◼ Describe the erogenous zones ◼ Explain human sexual behavior ◼ Characterize the diversity of sexual behavior ◼ Identify Sexually Transmitted Diseases ◼ Differentiate natural and artificial methods of contraception  REMINDER I want to make it clear that when approaching this topic on the sexual self, it should not just be as a biological process, but as a preparation to entering into and sustain an intimate, happy, and long time relationships in the future.  PHYSICAL DEVELOPMENT The beginning of adolescence is marked by rapid physical changes including: 1. Maturation of the reproductive system 2. Development of different sex characteristics  SEX CHARACTERISTICS 1. Primary Sex Characteristics - Physical characteristics that are present at birth.  SEX CHARACTERISTICS 1. Secondary Sex Characteristics - Develop during the onset of puberty. Women Men Enlargement of breasts Testicular growth Menstrual Cycle Sperm production Widening of hips Facial hair & other body hair Enlargement of buttocks Deepening of voice Growth of pubic hair  Hormones Natural substance that is produced in the body. It influence the way the body grows or develop. TYPES OF HORMONES 1. Testosterone 2. Estrogen 3. Progesterone REPRODUCTIVE ORGAN ABNORMALITIES Any intervention with the normal pattern of sex hormone production in the embryo results to abnormalities  REPRODUCTIVE ORGAN ABNORMALITIES 1. Pseudo hermaphrodite Individuals having accessory reproductive structures that do not match their gonads. Those who have reproductive organs opposite of the development of their body structure.  REPRODUCTIVE ORGAN ABNORMALITIES 2. Hermaphrodite Individuals who possess both ovarian and testicular tissues.  REPRODUCTIVE ORGAN ABNORMALITIES 3. Cryptorchidism Male testes formed in the abdominal cavity failed to descend to enter the scrotum.  REPRODUCTIVE ORGAN ABNORMALITIES 4. Phimosis Narrowing of foreskin of the male rep. structure and misplaced urethral openings.  DISEASES ASSOCIATED WITH THE REPRODUCTIVE SYSTEM Women Men Common inflammatory conditions: Vaginal Infections, if left untreated may lead to sterility. Prostatitis Urethritis Epididymitis Orchiditis Neoplasm – Abnormal growth of tissue and a characteristic of cancer. (eg Breast cancer, Cervix cancer, Prostate cancer)  Menopause Females no longer experience menstruation and is incapable of childbearing. Unlike Males, their reproductive capability seems unending and can still produce offspring.  Erogenous zones Parts of the body that are primarily receptive and increase sexual arousal when touched in a sexual manner. Common erogenous zone: *Mouth *Breasts *Genitals *Anus * They vary from person to one another  Human Sexual Behavior - Any activity (Solitary / Sociosexual) that induces sexual arousal. TYPES OF SEXUAL BEHAVIOR 1. Solitary Behavior Self gratification means self stimulation that leads to sexual arousal and sexual climax. Usually happens privately.  Human Sexual Behavior TYPES OF SEXUAL BEHAVIOR 2. Sociosexual Behavior Sexual activity between only one male and one female (Heterosexual behavior) or male to male and female to female (Homosexual behavior).  OTHER TERMS Petting Coitus When 2 people kiss and touch Insertion of male reproductive each other in a sexual manner prior organ to female reproductive to coitus.. organ.  Physiology of Human Sexual Response 1. Excitement Phase Abrupt and intense pleasure, increase in pulse rate, contractions of female organ and ejaculation of the male organ. May only last for few seconds. 2. Plateau Phase Generally of brief duration, is continued, orgasm usually occurs.  Physiology of Human Sexual Response 3. Sexual Climax Increase in pulse and blood pressure. Increased skin temperature, flushing and swelling of all distensible parts. Secretion of genital fluids, vaginal expansion, and increase in muscle tension. 4. Resolution Phase Return to normal or subnormal physiological state. Males return to normal while females are physically capable of repeated orgasms without intervening rest period required by males. SEXUAL PROBLEMS  Sexual Problems 1. Premature emission of semen Ejaculation happens sooner and occurs when a man reaches orgasm and ejaculate without control.  Sexual Problems 2. Erectile impotence Inability to get or keep erection firm enough to have sexual intercourse.  Sexual Problems 3. Ejaculatory impotence Inability to ejaculate in coitus.  Sexual Problems 4. Vaginismus Strong spasm of pelvic musculature constricting the female reproductive organ so that penetration is painful or impossible.  Sexually Transmitted Diseases Infections transmitted from an infected person to an uninfected person through sexual contact. * Chlamydia * Gonorrhea * Human Papillomavirus (HPV) * Herpes Simplex Virus (HSV) * Trichomonas Vaginalis * Syphilis * Chanchroid  CONTRACEPTIONS 1. Natural Method Preventing pregnancy without the use of medications or physical devices and helps people to know when to have a safe sexual intercourse. 2. Artificial Method Any product, procedure or practice that uses artificial or unnatural means to prevent pregnancy.  Natural Methods of Contraception 1. Abstinence Refraining from sexual intercourse and is the most effective natural birth control. 2. Calendar Method Also known as “Rhythm method”. Withholding coitus during the days that the woman is fertile..  Natural Methods of Contraception 3. Basal Body Temperature It indicates the woman’s temperature at rest. A slight decrease of temperature followed by a gradual increase in the BBT can be a sign that a woman has ovulated. 4. Cervical Mucus Method Basis of this method is change in cervical mucus during ovulation. Woman is fertile as long as the cervical mucus is copious and watery.  Natural Methods of Contraception 5. Symptothermal Method Combination of BBT Method and cervical mucus method. She should abstain coitus 3 days after rise in temperature / 4th day after the peak of mucus change. 6. Ovulation Detection Over- the-counter kit requiring a urine sample of a woman.  Natural Methods of Contraception 7. Coitus Interruptus (Withdrawal) Oldest method in preventing conception. Man withdraws the moment he ejaculates to emit spermatozoa outside of the female organ.  Artificial Methods of Contraception 1. Oral Contraceptives Also known as Pills. Suggested that a woman takes the first pill on the 1st Sunday after beginning of menstrual flow. 2. Transdermal Patch It contains both estrogen and progesterone. The woman should apply one patch every week for 3 weeks (upper/outer arm, upper torso, abdomen, buttocks). 4th week no patch because menstrual flow would occur  Artificial Methods of Contraception 3. Vaginal Ring Silicon ring inserted into the female reproductive organ , remains for 3 weeks and will be removed on the 4th week. 4. Subdermal Implants Two rod like implants inserted under the skin of the female during menses / 7th day of menstruation.  Artificial Methods of Contraception 5. Hormonal Injections Given once every 12 weeks intramuscularly. This prevents ovulation. 6. Intrauterine Device Small T-shaped object inserted into the uterus through the female reproductive organ. Inserted after a woman’s menstrual flow.  Artificial Methods of Contraception 7. Chemical Barriers Used to cause death of sperms before they can enter the cervix. (eg spermicides) 8. Diaphragm Circular rubber disk should be placed before coitus. It inhibits the entrance of sperm into the female reproductive organ. fitted only by physician  Artificial Methods of Contraception 9. Cervical Cap Made of soft rubber and fitted on the rim of the cervix. Shaped like a thimble with a thin rim and could stay in place for not more than 48 hours. 10. Male condoms Latex or synthetic rubber sheath place on the erect male reproductive organ before coitus to trap the sperm during ejaculation.  Artificial Methods of Contraception 11. Female condoms Latex rubber sheaths pre-lubricated with spermicide. Bound by 2 rings. Prevents fertilization of the egg by the sperm cells. 12. Surgical Methods On vasectomy, small incision is mad eon each side of the scrotum and blocked the passage of the sperm - END -
