  1. 1. The Reproductive System Nelia B. Perez RN, MSN Academic Coordinator College of Nursing
  2. 2. REPRODUCTIVE SYSTEM: FEMALE
  3. 3. Ovary = primary sex organ: paired, <ul><li>Produce eggs (ova) & secretes estrogen & progesterone </li></ul><ul><li>Posterior pelvic wall </li></ul><ul><li>Supported parietal peritoneum = broad ligament </li></ul>
  4. 4. Ovary – cont. <ul><li>Consists of four layers; </li></ul><ul><ul><li>1. Superficial (Germinal) Epithelium - single layer of cuboidal cells, thin outermost </li></ul></ul><ul><ul><li>2. Tunica Albuginea - a collagenous C.T. </li></ul></ul><ul><ul><li>3. Cortex – primary substance of the ovary </li></ul></ul><ul><ul><li>4. Medulla - innermost, vascular area </li></ul></ul>
  5. 5. Oogenesis: egg formation <ul><li>Before birth - Ovary contains about one  million oogonia (immature egg cells, 46 chromosomes). </li></ul><ul><li>At birth - SOME of the oogonia grow and begin into the 1st Meiotic division but stop in Prophase I = Primary Oocytes. </li></ul><ul><li>Primordial Follicle = The immature Primary Oocyte + flattened, randomly-arranged Follicle Cells </li></ul>
  6. 6. Oogenesis <ul><li>Puberty – (Primary Follicle formation) FSH stimulates some Primordial Follicles to grow bigger by developing numerous layers of uniformly-arranged, cuboidal Follicle Cells surrounding a Primary Oocyte   </li></ul>
  7. 7. Oogenesis <ul><li>Secondary Follicle formation -LH stimulates, the Follicle Cells to secrete a nutritive fluid which collects into several fluid-filled cavities called Vesicles which aggregate together to form an Antrum (fluid-filled cavity). Also, a protective layer develops around the Primary Oocyte = Zona Pellucida. The Primary Oocyte plus the Antrum, multiple layers of Granulosa Cells, and the Zona Pellucida = Secondary Follicle. </li></ul>
  8. 8. Oogenesis <ul><li>With continued hormonal stimulation, the Granulosa (Follicle) Cells continue to increase in number and to secrete the nutritive fluid, and the Antrum enlarges to its maximum size. At this stage, the follicle is known as a Graafian (Mature, Vesicular) Follicle.   </li></ul><ul><li>In the Graafian Follicle, under the influence of LH , the Primary Oocyte undergoes completion of the 1st meiotic division & begins into the 2nd meiotic division, but stops in Metaphase II = Secondary Oocyte   </li></ul>
  9. 9. Oogenesis -menstruation <ul><li>Once a month (at approximately day 14 of the normal 28 day cycle), under the influence of LH, the Graafian Follicle is induced to rupture = Ovulation. </li></ul><ul><li>  A Secondary Oocyte is released, surrounded by: </li></ul><ul><ul><li>1. Zona pellucida - a protective gel layer made by the granulosa cells </li></ul></ul><ul><ul><li>2. Corona radiata - two layers of granulosa cells   </li></ul></ul><ul><li>The remaining portion of the Graafian Follicle, under the influence of LH, is induced enlarge and to form a Corpus Luteum. It will produce Estrogen & Progesterone which thickens the stratum functionalis of the uterus.   </li></ul>
  10. 10. Secondary Sex Organs –Fallopian tubes <ul><li>Fallopian tubes: 4 parts; fimbriae, infundibulum, ampulla, isthmus, transport Oocyte to uterus </li></ul><ul><ul><li>1. Fimbriae - motile processes which hang over ovary. Draw secondary oocyte into Uterine Tube </li></ul></ul>
  11. 11. Secondary sex organs- Uterus <ul><li>3 Parts; Fundus, Body, & Cervix </li></ul><ul><li>Histology: </li></ul><ul><ul><li>a. Endometrium </li></ul></ul><ul><ul><ul><li>i. Stratum functionalis - shed during menses, implantation occurs here </li></ul></ul></ul><ul><ul><ul><li>ii. Stratum basale - deep, very vascular, never shed, replaces Stratum Functionalis </li></ul></ul></ul><ul><ul><li>b. Myometrium - middle, smooth m. </li></ul></ul><ul><ul><li>c. Perimetrium - outer, C.T.   </li></ul></ul>
  12. 12. Secondary sex organs - Vagina <ul><li>Vagina: copulatory organ, opening = Vaginal Orifice, in most newborns it is covered by a hymen (vascular connective tissue) </li></ul>
  13. 13. Secondary sex organs - Vulva <ul><li>External Genitalia = Vulva </li></ul><ul><ul><li>Mons pubis - hair covered fat pad </li></ul></ul><ul><ul><li>Labia majora - hair covered skin folds </li></ul></ul><ul><ul><li>Labia minora - smaller, hairless skin folds. Anteriorly, they fuse to form a prepuce (over Clitoris) </li></ul></ul><ul><ul><li>Vestibule: space between labia minora. Contains: </li></ul></ul><ul><ul><ul><li>a. Vaginal orifice </li></ul></ul></ul><ul><ul><ul><li>b. Urethral orifice </li></ul></ul></ul><ul><ul><ul><li>c. Openings for Vestibular (Bartholin's) glands </li></ul></ul></ul><ul><ul><li>Clitoris: contains 2 columns of erectile tissue = corpora cavernosa </li></ul></ul>
  14. 14. Secondary sex cells – Mammary Glands <ul><li>Mammary glands: modified sweat glands. </li></ul><ul><li>Divided into lobules which are subdivided into lobules. The lobules contain Alveolar Glands </li></ul><ul><li>  Milk flows through the Lactiferous ducts & is stored in the Lactiferous sinuses just below the areola. </li></ul><ul><li>Milk leaves the sinuses via Lactiferous Ducts to Nipple </li></ul><ul><li>  Areola - pigmented area around nipple, many oil glands   </li></ul>
  15. 17. <ul><li>Testes (singular = testis) </li></ul><ul><li>Male gonads </li></ul><ul><li>Suspended outside the abdominal cavity in the scrotum </li></ul><ul><li>Hang outside the body to ensure optimal temperatures for sperm production (a few degrees below body temperature is required) </li></ul><ul><li>Testes descend into scrotum during last 2 months of fetal development </li></ul><ul><ul><li>If testes do not descend, sperm can not develop properly </li></ul></ul><ul><ul><ul><li>Male may become sterile </li></ul></ul></ul><ul><ul><ul><li>Increased chance of testicular cancer & injuries </li></ul></ul></ul><ul><li>**Testes are able to move in and out of abdominal cavity to maintain proper temperature for spermatogenesis </li></ul><ul><li>2 Functions </li></ul><ul><ul><li>Make s perm in seminiferous tubules, maturing sperm are moved to the epididymis </li></ul></ul><ul><ul><li>Make hormones : androgens and testosterone </li></ul></ul>
  16. 19. <ul><li>Seminiferous Tubules~250m in length! </li></ul><ul><li>site of spermatogenesis (meiosis) </li></ul><ul><li>also produce inhibin (negative -feedback vehicle to regulate the production of testosterone ) </li></ul><ul><li>Interstitial Cells </li></ul><ul><li>Site of testosterone production </li></ul><ul><li>Epididymis </li></ul><ul><li>area where sperm mature and begin to gain motility and the ability to fertilize </li></ul><ul><li>storage area for sperm </li></ul><ul><li>tightly coiled tubules </li></ul>
  17. 22. <ul><li>Spermatogenesis </li></ul><ul><li>After puberty this is ongoing (unlike females) </li></ul><ul><li>Usually100-300 million sperm delivered per ejaculate </li></ul><ul><ul><li>Only 15% are viable, of this only 400 survive to fertilize egg </li></ul></ul><ul><li>Vas deferens (plural = vas deferentia) (also ductus deferens) </li></ul><ul><li>storage area for sperm </li></ul><ul><li>tube which carries the sperm to the ejaculatory duct and the urethra </li></ul><ul><li>Smooth muscle contractions propel the sperm into the vas deferens </li></ul>
  18. 23. <ul><li>Penis </li></ul><ul><li>spongy, erectile tissue containing distensible blood spaces </li></ul><ul><li>becomes erect during sexual arousal due to an increase in arterial blood flow to the penis caused by parasympathetic nerves </li></ul><ul><li>flaccid if not sexually aroused </li></ul>
  19. 24. P3: List the functions of the seminal fluid <ul><li>Semen ( seminal fluid) </li></ul><ul><li>thick, whitish fluid </li></ul><ul><li>contains sperm and fluids from the seminal vesicles, the prostate and Cowper’s gland. </li></ul><ul><li>is used for nutrition , motility , neutralization, and lubrication </li></ul><ul><li>Seminal Vesicles : </li></ul><ul><li>lie at base of bladder </li></ul><ul><li>secrete a thick, clear fluid containing fructose (energy), prostaglandins (chemical signal in female to trigger rhythmic contractions of smooth muscle in female – facilitates movement of sperm towards egg </li></ul><ul><li>Prostate gland </li></ul><ul><li>Secretes a milky alkaline buffer that protects the sperm from the acidic environment of the vagina. </li></ul><ul><li>Helps activate sperm, helps with motility </li></ul>

  51. 66. BREAST SELF EXAMINATION
  52. 67. THE BREAST <ul><li>It has an important role in modern culture </li></ul><ul><li>Often viewed as measures of sexuality , femininity and attractiveness because it is visible for its size and shape. </li></ul><ul><li>However, it is a secondary sex characteristic </li></ul><ul><li>Its physiologic function is milk secretion to feed infants </li></ul>
  53. 68. Clinical value <ul><li>Experience has verified that 90% of breast cancers are found by women themselves </li></ul><ul><li>When women discover lumps in their breasts at ea very early stage, surgery can save 70-80% of proven cases </li></ul>
  54. 69. Recommendation <ul><li>All women age 20 years and older perform BSE on a monthly basis. Beginning in their 20’s, women should be told about the benefits and limitations of breasts self examination. The importance is prompt reporting of any new breast symptoms to a health professional should be emphasized. </li></ul><ul><li>All women ages 29 to 39 should have clinical examinations every 3 years preferably be part of a periodic health examination. </li></ul><ul><li>All women ages 40 years and older have regular (every 1 to 2 years) mammograms. </li></ul><ul><li>Asymptomatic women ages 40 and older should continue to receive clinical breast examination preferably be part of a periodic health examination annually. </li></ul><ul><li>Screening decisions for older women should be individualized by considering the potential benefits and risk of mammography in the context of the current health status and estimated expectancy. As long as woman is in good health and would be candidate for treatment, she should continue to be screened with mammography. </li></ul>
  55. 70. Advantages of BSE Women can use BSE to asses their breasts. When they perform BSE properly and regularly, they can not any changes in their breasts and seek further evaluation. Examination should be done every month and at the end of menses in all menstruating women.
  56. 71. Barrier to BSE The major barrier to BSE is the lack of CONFIDENCE
  57. 72. Physical assessment findings in a healthy adult <ul><li>By inspection </li></ul><ul><li>By palpation </li></ul>
  58. 73. By inspection the breast should be: <ul><li>Symmetrical, full, rounded, smooth in all portions, without dumpling, retractions or masses </li></ul><ul><li>Faint, even vascular pattern and striae are noted </li></ul><ul><li>Nipples everted, areola even </li></ul><ul><li>Axillae even color, without masses or rash </li></ul>
  59. 74. In palpation the breast should be: <ul><li>Firm and without masses, lumps, local areas with warmth, or tenderness </li></ul><ul><li>Nipples should have no discharges </li></ul><ul><li>Axillae should be smooth and node are nonpalpable </li></ul>
  60. 75. Assessment interview <ul><li>Sexual health history </li></ul><ul><li>Are you currently sexually active? With men, women, or both? </li></ul><ul><li>Describe the positive or negative aspects of your sexual functioning </li></ul><ul><li>Do you have difficulty with sexual desire? Arousal? Orgasm? Satisfaction? </li></ul><ul><li>Do you experience any pain with sexual interaction? </li></ul><ul><li>If there are problems, how have they influenced how you feel about yourself? Have have they affected your partner? How have they affected the relationship? </li></ul><ul><li>Do you expect your sexual functioning to be altered because of your illness? </li></ul><ul><li>What are your partner’s concern about your future sexual functioning? </li></ul><ul><li>Do you have any other sexual questions or concerns that have not been addressed? </li></ul>
  61. 76. Assessment interview <ul><li>Breast History </li></ul><ul><li>Ask the client about breast pain or tenderness and its occurrences in relation to menstrual cycle. </li></ul><ul><li>Ask whether the woman has had in the past or currently has breast lumps or masses. If a lump is present, ask the woman to describe its location, onset and size and whether it is painful </li></ul><ul><li>Determine whether the lump has changed shape, size, consistency, or degree f redness since it was first noticed </li></ul><ul><li>Ask about nipple discharge, which is abnormal in women who are not pregnant or lactating. If there is a discharge, determine the color, consistency, amount and odor. </li></ul><ul><li>Ask whether the woman perform BSE regularly </li></ul><ul><li>Note whether the woman include axillary nodes in BSE. </li></ul><ul><li>Ask for her HISTORY of breast cancer in her blood-related FEMALE relatives – mother, sisters, maternal grandmother or maternal aunts. It indicates an increased risk of breast cancer if she has any family history of breast cancer. </li></ul>
  62. 77. Identifying clients at risk <ul><li>Altered body structure or function due to trauma, pregnancy, recent childbirth, anatomic abnormalities of genitals or disease </li></ul><ul><li>Physical, psychosocial, emotional, or sexual abuse; sexual assault </li></ul><ul><li>Disfiguring conditions, such as burns, skin conditions, birthmarks, scars (e.g. mastectomy) and ostomies </li></ul><ul><li>Specific medication therapy that causes sexual problems </li></ul><ul><li>Temporary or long term impaired physical ability to perform grooming and maintain sexual attractiveness </li></ul><ul><li>Value conflicts between personal beliefs and religious doctrines </li></ul><ul><li>Loss of partner </li></ul><ul><li>Lack of knowledge or misinformation about sexual functioning and expression </li></ul>
  63. 78. SIGNS OF BREAST CANCER <ul><li>Elevation </li></ul><ul><li>Asymmetry </li></ul><ul><li>Bleeding </li></ul><ul><li>“Orange Peel” skin </li></ul><ul><li>Nipple Retraction </li></ul>
  64. 79. Women are screened for breast cancer in 3 ways: <ul><li>Mammography – roentgenography of breasts without injection of contrast meduim. It is most sensitive. </li></ul><ul><li>3 views : </li></ul><ul><li>Craniocaudal </li></ul><ul><li>Mediolateral </li></ul><ul><li>Axillary </li></ul>
  65. 80. Women are screened for breast cancer in 3 ways: <ul><li>2. Clinical Breast Examination - clinical breast exam is an examination by a doctor or nurse, who uses his or her hands to feel for lumps or other changes </li></ul><ul><li>3. Breast self-exam. A breast self-exam is when you check your own breasts for lumps, changes in size or shape of the breast, or any other changes in the breasts or underarm (armpit). </li></ul>
  66. 81. BIOPSY is a medical test involving the removal of cells or tissues for examination. <ul><li>Aspiration – a syringe and g 18 needle is used to aspirate tissue from the site which is under local anesthesia. The specimen is spread on a glass slide, fixed, stained and sent to the laboratory </li></ul><ul><li>Incisional – a piece of tissue is obtained in the operating room, sent to the laboratory fro frozen section which is the stained and examined under the microscope. </li></ul>
  67. 82. Classification of Breast Tumors and Preferred Method of Treatment <ul><li>Variable depending upon nature of metastasis, such as bone, sofe tissue, etc. </li></ul><ul><li>Radiation therapy to primary lesion or metastasis </li></ul><ul><li>Hormonal theraphy, hypophysectomy, adrenalectomy </li></ul><ul><li>Chemotherapy </li></ul><ul><li>Oophorectomy </li></ul>Stage IV Distant Metastasis <ul><li>Variable depending on extensiveness: </li></ul><ul><li>Simple mastectomy with radiation </li></ul><ul><li>Simple mastectomy with excision of large axillary nodes </li></ul><ul><li>Radiation therapy alone if tumor is fixed to the chest wall </li></ul>Stage III Breast Mass locally extensive; axillary supraclavicular and internal mammary nodes positive Radical mastectomy preferred with or without postoperative irradiation Stage II Breast Mass Localized; axillary nodes positive Radical mastectomy preferred by surgeons. Some prefer simple mastectomy plus or without irradiation. Stage I Breast Mass Localized; all nodes negative Treatment Clinical Anatomic Observation
  68. 83. STEPS IN BREAST SELF EXAMINATION <ul><li>Inspection before a mirror </li></ul><ul><li>Palpation: Lying Position </li></ul><ul><li>Palpation: Standing or sitting </li></ul>
  69. 84. Inspection before a mirror <ul><li>Stand and face a mirror with your arms relaxed at your sides or arms resting on your hips; then turn to the right and left for a side view look. (look for any flattening in the side view </li></ul>
  70. 85. <ul><li>… continuation </li></ul><ul><li>Bend forward from the waist with arms raised overhead </li></ul><ul><li>Stand straight with arms raised over the head and move the arms slowly up and down at the sides. (look for free movement of the breasts over the chest wall) </li></ul><ul><li>Press your arm firmly together at the chin level while the elbows are raised to shoulder level. </li></ul>
  71. 86. Palpation: Lying Position <ul><li>Place a pillow under your right shoulder and place the right hand behind your head. This position distributes breast tissues more evenly on the chest. </li></ul><ul><li>Use the finger pads (tips) of the three middle fingers (held together)on your left hands to feel the lumps. </li></ul><ul><li>Press the breast tissue against the chest wall firmly enough to know hoe your breast fells. A ridge of firm tissue in the lower curve of each breast is normal. </li></ul><ul><li>Use circular motions systematically all the way around the breasts as many times as necessary until the entire breast is covered. </li></ul><ul><li>Bring your arm down to your side and feel under your armpit, where breast tissues are also located. </li></ul><ul><li>Repeat the exam on your left breast using the right finger pads of your right hand . </li></ul>
  72. 87. Palpation: Standing or Sitting <ul><li>Repeat the examination of both breasts while upright with one arm behind your head.

  112. 130. Assessment of Burn Injury Takes several weeks to heal. Scarring may occur. Takes several weeks to heal. Scarring may occur. Superficial: Pink or red; blisters form (vesicles); weeping, edematous, elastic. Superficial layers of skin are destroyed; wound moist and painful. Deep dermal: Mottled white and red: edematous reddened areas blanch on pressure. May be yellowish but soft and elastic – may or may not be sensitive to touch; sensitive to cold air. Hair does not pull out easily Second degree In about 5 days, epidermis peels, heals spontaneously. Itching and pink skin persist for about a week. No scarring. Heals spont. If it does not become infected w/in 10 days - 2 weeks. Pink to red: slight edema, which subsides quickly. Pain may last up to 48 hours. Relieved by cooling. Sunburn is a typical example.

  120. 138. <ul><li>MANAGEMENT OF THE BURN INJURY </li></ul><ul><li>Phases of Management of the Burn Injury </li></ul>Resuscitative phase - begins w/ the initiation of fluids and ends when capillary integrity returns to near normal levels and the large fluid shifts have decreased - the amount of fluid administered is based on the client’s weight and extent of injury - most fluid replacement formulas are calculated from the time of injury and not from the time of arrival at the hospital - the goal is to prevent shock by maintaining adequate circulating blood volume and maintaining vital organ perfusion Emergent phase - begins at the time of injury and ends with the restoration of capillary permeability, usually at 48-72 hours after the injury - the 1 ˚ goal is to prevent hypovolemic shock and preserve vital organ functioning - includes prehospital care and emergency room care
  121. 139. Rehabilitative phase - final phase of burn care - overlaps the acute care phase and goes well beyond hospitalization - goals of this phase are designed so that the client can gain independence and achieve maximal function Acute phase - begins when the client is hemodynamically stable, capillary permeability is restored, and diuresis has begun - usually begins 48 - 72 hours after the time of injury - emphasis during this phase is placed on restorative therapy, and the phase continues until wound closure is achieved - the focus is on infection control, wound care, wound closure, nutritional support, pain management, and physical therapy
  122. 140. FLUID SHIFTING IN BURNS OLIGURIC PHASE – Intravascular to Interstitial Hct increased, renal output decreased, hyper K, hypo Na, hypo CHON, metabolic acidosis DIURETIC PHASE – Interstitial to Intravascular Hct decreased, renal output increased, hypo K, hypo Na, hypo CHON, metabolic acidosis
