  1. The Plumbing Sexual Anatomy and Disorders of Sexual Development

  2. Female Anatomy

  3. Female Reproductive System in Context

  4. This is not a vagina

  5. The Clitoral Complex

  6. THE HORMONES   Endocrine glands secrete their product into the system 1.      Hypothalamus –structure in the brain that controls the pituitary gland 2.      Pituitary—pea shaped gland, base of brain, master gland, stimulates all the other glands

  7.   Hormones Gonadotropins—sex hormones secreted by pituitary that stimulates the gonads to produce hormones. a)     Follicle Stimulating Hormone (FSH) – released by pituitary, instructs the ovaries to prepare an egg to be released b)     Lutenizing Hormone (LH)—stimulates ovulation c)     Prolactin – pituitary hormone, stimulates production of milk from mammaries

  8. Sex Hormones Estrogen—produced by ovaries *level in blood controls menstrual cycle* Progesterone—released by corpus lutuem to signal endometrium to develop in preparation for a zygote Androgens –“male” sex hormones

  9. MENSTRUATION Menstrual phsiology -If zygote not implanted then no hormones to sustain corpus luteum, so it disintegrates. -With no progesterone being released menstruation is then signaled Phases of the menstrual cycle 1. Proliferative phase 2. Secretory/Luteal phase 3. Ovulatory phase 4. Menstrual phase

  10. A.    Effects of menstruation on the body and mind B.     Menstrual problems 1.      Dysmenorrhea 2.      Amenorrhea 3.      Premenstrual syndrome (PMS) 4.      Endometriosis C.The menstrual cycle and sex increased HIV

  17. Instead

  18. The Keeper

  19. Washable Pads

  20. MENOPAUSE Symptoms of perimenopause and menopause Treatment for menopause • Estrogen Replacement Therapy - HRT

  21. THE BREASTS

  22. Breast Problems 1.      The breasts a)     Breast cancer b)     Cysts c)     Fibroidenoma non cancerous tumor d)     Nipple discharge e)     Breast abscess

  23. Male Anatomy

  24. The internal genitals 1. The urethra 2. The corpora cavernosa and corpus spongiosum – fill with blood, erection 3. The testis a)     Vas deferens -- tube through which sperm is passed b)     Seminiferous tubules – structures in the testicles that actually produce sperm c)     Epididymis -- where sperm are stored and nourished

  25. The pathway of sperm a)     Seminal vesicles sacs that secrete nutrients to sperm b)    Ampulla where sperm are provided with nutrients from the seminal vesicles c)     Prostate gland structure that secretes fluid into semen before ejaculation. d)    Cowper’s gland pre-ejaculate e)Ejaculation and orgasm expulsion of semen from penis and peak of sexual tension, sensory pleasure

  26. The external genitals

  27. Circumcision

  28. Foreskin Restoration • National Organization for Foreskin Restoration - http://www.norm.org/ • Why? Increase sensation, feeling of having been robbed of sexual pleasure

  29. Homemade device foreskin stretching • Two year process • http://www.foreskinrestore.com/

  30. Erection + Ejaculation • Most often, stimulation of an erection plays a big part in ejaculation • HOWEVER ejaculation can happen without an erection • Stimulation of the prostate is one way this can happen

  31. Sperm • Mature sperm .0024 inches • Acrosome, head, neck, midpiece and tail • Adult male produces over 100 million sperm cells each day

  32. Ejaculation • Muscle contractions • 300 million sperm expelled in a single ejac. • Valve to bladder closes to prevent passage of urine • A tablespoon of semen contains approximately six calories. Semen does contain protein, but it also contains all kinds of chemicals and minerals, including water, sugar, calcium, chlorine, magnesium, nitrogen, vitamin B12, and zinc. But it does not contain enough of any of these things to be considered "nutritious."

  33. HORMONES A. PUBERTY 1.      Releasing factors 2.      Estrogen/progesterone 3.      Testosterone B.Male climacteric (male menopause)

  34. Erectile dysfunction • hormone supplements • therapy • vacuums • injections • implants • surgery • pellets and…

  35. Homologous Reproductive Structures • Homologous: corresponding in structure and in origin, but not necessarily in function • Essentially, body parts that develop from same origins
