  • 1. HumAN Sexuality By: Miss Shenell A. Delfin Lecturer NCM 101
  • 2.
    • A dirty book is rarely dusty
  • 3. Introduction of Human sexuality
    • It is the process by which people experience and express themselves as sexual beings.
    • Sexuality has been a consistent focus of curiosity, interest, and analysis to humankind.
  • 4. Aspects of sexual behavior Philosophical Sociological Psychological Anatomical Physiological Cognitive Learning Cultural Political Legal Moral Ethical Theological Spiritual Religious
  • 5. Anatomical and physiological aspect
  • 6. Teng-teng Va-jj Meet your new friends!!
  • 7. Key terms:
    • Adrenarche- development of pubic and axilliary hair
    • Thelarche- beginning of breast development
    • Menarche- first menstrual period
    • Gonad- is a body system that produces sex cells.
    • Oocytes- cells that develop into eggs
  • 8.
    • Oogenesis- the process where mature egg cells are produced in the ovary.
    • Spermatogenesis- production of sperm
    • Aspermia- absence of sperm
    • Oligospermia- fewer than 20 million sperms per ml
    • Gynecology- study of female reproductive system
    • Andrology- study of male reproductive system
    • Obstetrics- study on women during pregnancy & childbirth
  • 9. Biological Bases of Human Sexuality
    • Genetic basis
      • XX = female
      • XY = male
    • Gonadal basis- ovary & testis
    • Structural development
      • Male genital development
      • Female genital development
    • Biological sexuality and the childhood years
    • Puberty
      • Females: Menarche & telarche
      • Males:
  • 10. Note homology between the penis and clitoris and between the scrotum and the labia majora.
  • 11. Male Reproductive System
    • Testes
      • Firm, smooth and egg shape
      • Leydig’s cells- production of testosterone
      • Seminiferous tubule- production of spermatozoa
    • Scrotum- support the testes & regulate temperature of the sperm
    • DUCTS
    • Epididymis- carries away sperm from testes
    • Vas deferens- carries sperm from epididymis
    • Seminal vesicles- a gland that secrete a viscous portion of semen,high in basic sugar, protein, &prostaglandin
  • 12. Male Reproductive System
    • Ejaculatory ducts- empties the fluid from the seminal vesicles and pass through the prostate gland to urethra.
    • Prostate gland- secretes thin alkaline fluid that protects sperm from being immobilized.
    • Cowpers gland- secretes alkaline fluid that ensure the safe passage of spermatozoa.
    • Semen is derive from the prostate gland 60 %, seminal vesicles 30 %, epididymis 5%, & cowpers gland 5 %
  • 13. Male Reproductive System
  • 14. Role of androgen
    • Levels of the primary androgenic hormone, testosterone are low in males until puberty.
    • 12-14 years old the testosterone level rise to influence the further development of the testes, scrotum, penis, prostate and seminal vesicles; the appearance of male pubic hair, axilliary, and facial hair; laryngeal enlargement, voice change & production/maturation of spermatozoa.
  • 15. Male reproductive hormones Hormone Where produced Functions Testosterone Testes, adrenal glands Stimulate sperm production, secondary sex characteristics, sex drives GnRh Hypothalamus Stimulate pituitary during sperm production FSH Pituitary Sperm production in testes LH Pituitary Stimulates testosterone production within testes Inhibin Testes Regulates sperm production by inhiting release of FSH Relaxin Prostate Increase sperm motility

  • 20.  
  • 21. Female Reproductive System
    • Mons pubis- protect the junction of the pubic bone from trauma
    • Labia majora- enclosing the clitoris, urethral opening, & vaginal entrance
    • Labia minora- smaller folds that is sensitive to touch & swell during sexual arousal, doubling or tripling in size.
    • Clitoris- center of sexual arousal , concentration of nerve endings & sensitive to stimulation.
    • Vestibule- encloses labia minora
  • 22. Female Reproductive System
    • Bartholin’s gland- secretes small amount of moisture during arousal.
    • Hymen- (named for the roman God of marriage) thin membrane covering the introitus.
    • Introitus- opening of the vagina
    • Vagina- (latin word sheath) 2 reproductive fxn: encompasses the penis during coitus & birth canal through which an infant is born.
  • 23.  
  • 24. Female Reproductive System
    • Uterus- or womb. Expands during pregnancy to the size of a football or larger.
    • Cervix- pear-shaped tapered end extending down and opening of vagina
    • Ovaries- female gonad that produces gametes. Hormone production: estrogen & progesterone
    • Fallopian tubes- convey the ovum from the ovaries to the uterus & to provide place for fertilization.
  • 25.  
  • 26. Female Reproductive System
  • 27. Role of estrogen
    • When triggered @ puberty by FSH, ovarian follicles in females begin to excrete high levels of hormone estrogen (3 compounds: estrone E1, estraidol E2, estriol E3)
    • This increase influence the development of uterus, fallopian tubes, & vagina; typical female fat distribution & hair patterns; breast development (thelarche).
  • 28. Female reproductive hormones Hormone Where produced Functions Estrogen(estradiol, estrone, estriol) Ovaries, adrenal glands, placenta during pregnancy Promotes maturation of reproductive organs, secondary sex characteristics,& GD during puberty; regulates menstrual cycle; sustains pregnancy Progesterone Ovaries, adrenal glands Promotes breast dev’t, maintains uterine lining, regulates menstrual cycle GnRH- gonadotropin-releasing hormone Hypothalamus Promotes maturation of gonads, regulates menstrual cycle FSH Pituitary Regulates ovarian fxn and maturation of follicles
  • 29. Female reproductive hormones Hormone Where produced Functions LH Pituitary Assist in production of estrogen & progesterone, regulates maturation of ovarian follicle, triggers ovulation HCG- human chorionic gonadotropin Embryo and placenta Helps sustain pregnancy Testosterone Adrenal glands & ovaries Helps stimulate sexual interest Oxytocin Hypothalamus Stimulate uterine contraction during childbirth prolactin pituitary Stimulates milk production

  • 32. Menstrual cycle
    • Menstrual cycle is a periodic uterine bleeding in response to cyclic hormonal changes. It is the process that allows conception and implantation of new life.
    • Phases of menstrual cycle:
    • Proliferative phase- days 6-14
    • Secretory phase- days 15-21
    • Pre-menstrual phase- days 22-28
    • Menstrual phase- days 1-5
  • 33. Proliferative phase
    • Immediately after menstruation
    • Hypothalamus (GnRH)
    • Anterior Pituitary gland(stimulate)
    • Secretion of FSH
    • Produce estrogen
    • Thickening of the endometrium
    • Estrogen increase in the blood stream
  • 34.
    • Suppresses the secretion of the FSH
    • Favors the secretion of the LH produced by PG
    • Graaffian follicle burst
    • Ovum degenerates into the fallopian tube
    • LH stimulates ovulation
    • Secretory phase
  • 35. Secretory phase
    • After ovulation,LH initiates the production of progesterone
    • Initiates the development of corpus luteum
    • Cavity of graafian follicle replaced by corpus luteum
    • Secretes progesterone and some estrogen
    • Acts on endometrium
    • Pre-menstrual phase
  • 36. Pre-Menstrual phase
    • If fertilization occurs
    • Corpus luteum will stimulate the production of progesterone
    • Endometrium becomes thicker and vascular
    • Ready for implantation
  • 37. Pre-menstrual phase
    • If fertilization does not occur
    • Corpus luteum begins to regress
    • Menstrual phase
  • 38. Menstrual phase
    • Corpus luteum degenerates
    • Decrease production of hormones in the endometrium
    • Blood levels of estrogen & progesterone drops

  • 45. Human
    • Reproduction
  • 46. Reproductive Process: The Implications of Cooperation Between the Sexes
    • The sperm enters the cell wall of the ovum and fertilizes the nucleus, starting the process of mitosis that will lead to the embryo, fetus, and infant (upper left)
    • Of course, there are misconceptions as to the facts of life. . . (upper right)
  • 47. Psychological and sociological aspect
  • 48. Sex, gender, and gender roles: what’s the difference?
    • Sex- refers to whether one is biologically female or male, based on genetic and anatomical sex.
    • Genetic sex- refers to one’s chromosomal and hormonal sex characteristics.
    • Anatomical sex- refers to physical sex: gonads, uterus, vulva, vagina, penis and so on.
  • 49. Sex, gender, and gender roles: what’s the difference?
    • Gender- is femininity or masculinity, the social and cultural characteristics associated with biological sex.
    • Gender identity- is the gender a person believes him or herself to be.
    • Gender role s- the way that a person acts as a female or male. Public expression of gender identity.
  • 50. Sex, gender, and gender roles: what’s the difference?
    • Gender-role stereotype- is a rigidly held over simplified, and over generalized belief that all males and females possess distinct psychological & behavioral traits.
    • Examples:
    • “ women are more interested in relationship than sex”
    • “ men who wear pink shirt are gays”
    • “ males are generally taller than females”
    • “ men: sex first love later, women: love first sex later”

    • Commodification
    • Ex. Advertisements using bodies of women in wine commercials
    • subordination
    • Ex. In some families, the decision of the father is final & absolute, even if it is against the wife or children
  • 52. Sexual Orientation
    • Sexual orientation describes the object of a person's sexual impulses:
      • - Heterosexual (opposite sex),
    • - Homosexual (same sex),
    • - Bisexual (both sexes). - Transexuality (desire to be a member of the opposite sex)
  • 53.
    • A “masculine” man is attracted to women.
    • A “feminine” woman is attracted to men.
    • “ If a man is gay, he cannot be masculine.”
    • “ if a woman is lesbian, she cannot be feminine.”
  • 54. Theories of gender role development
    • Cognitive – Development theory – process that gender – role development emerges through children's growing cognitive awareness of their identity.
    • Behavioral theory – gender role behavior are conditioned by the environment. 
    • Social – Learning theory – gender – role are learned through invitation of sex-typed behaviors.
    • Identification theory – a psychoanalytic theory that suggest a child develops a gender role by interacting closely with and emulating the behavior of the parent of the same sex.

    • Same-sex marriages- ???????
  • 61. Clitoridectomy and Circumcision
    • Clitoridectomy is the removal of the clitoris in women; it eliminates sexual pleasure
    • Often, the term “circumcision” is applied to both women and men, but it obscures the distinction; in men, only the foreskin of the penis is opened and removed.
    • Above: Kipsigis girls (in veils) of East Africa are preparing for clitoridectomy.
    • Often, parts of the vulva are sewn afterward to ensure virginity.
    • Circumcision in males has also been questioned as a valid practice as well, as suggested in this political cartoon.
  • 62.  
  • 63. Female genital mutilation with clitoris possibly removed and labia sewed shut (female circumcision) Opening left for menstrual blood to escape.

  • 73. Four-phase cycle of Physiological Responses
    • Phase-1
    Desire Orgasm Excitement Resolution Phase-2 Phase-3 Phase-4 Plateau phase
  • 74. Four-phase cycle of Physiological Responses The sequence of responses can overlap and fluctuate
  • 75. Phase 1: Desire
    • The desire (or appetitive) phase, identified solely through physiology, reflects the psychiatric concern with motivations , drives , and personality .
    • The phase is characterized by sexual fantasies and the desire to have sexual activity .
  • 76. Phase 2: Excitement
    • The excitement and arousal phase, brought on by psychological stimulation (fantasy or the presence of a love object) or physiological stimulation ( Foreplays-stroking or kissing) or a combination of the two, consists of a subjective sense of pleasure.
  • 77. Phase 3: Orgasm
    • Peaking of sexual pleasure,
    • Release of sexual tension
    • Rhythmic contraction of the perineal muscles and the pelvic reproductive organs.
    • A subjective sense of ejaculatory inevitability triggers men's orgasms. The forceful emission of semen. 4 to 5 rhythmic spasms of the prostate, seminal vesicles, vas, and urethra.
    • In women, orgasm is characterized by 3 to 15 involuntary contractions of the lower third of the vagina and by strong sustained contractions of the uterus, flowing from the fundus downward to the cervix.
  • 78. Phase 4: Resolution
    • Resolution consists of the disgorgement of blood from the genitalia (detumescence). Body back to its resting state.
    • If orgasm occurs: resolution is rapid, a subjective sense of well-being, general and muscular relaxation.
    • If orgasm does not occur : resolution may take from 2 to 6 hours and may be associated with irritability and discomfort.
    • After orgasm, men have a refractory period (several minutes to many hours) when they cannot be stimulated to further orgasm. Women do not have a refractory period and are capable of multiple and successive orgasms.
