2. Hormonal Contraception How It Works, Various Forms

3. Hormonal Contraceptives: Mechanism of Action Synthetic estrogen and/or synthetic progesterone Combination hormone contraceptives halt ovulation No egg = no pregnancy HybridMedical video: Ovulation (YouTube) HybridMedical video: Ovulation

4. Hormone-Based Contraception Estrogen – Usually ethinyl estradiol Progestin – Many types – Types vary in terms of side effects Blood lipids Break-through bleeding Weight gain/metabolism Acne Source: Dawn Stacey, About.com

5. Estrogen Estrogen suppresses development of follicle within ovary Estrogen changes the endometrial lining, making the uterine environment less accommodating to a fertilized ovum

6. Estrogen Estrogen makes progestin activity stronger Progestin manipulates one of the hormones responsible for ovulation So, even if estrogen does not completely prevent follicle development, it works with progestin to prevent ovulation

7. Progestin Progestin thickens cervical mucus – Thicker mucus hampers sperm movementmucus Progestin also changes the endometrial lining – Reduces likelihood for egg implantation Progestin-only methods may not inhibit ovulation – Varies from one cycle to another – Method dependent (Depo-Provera inhibits ovulation, minipills may not) – Effectiveness due to cervical mucus, endometrial changes

8. Hormonal Contraception: Contraindications Women with history of venous clots, coronary artery disease, stroke, diabetes with blood vessel damage, high blood pressure, breast cancer, abnormal bleeding, liver problems Smoking Obesity?

26. Sterilization

27. Sterilization: Vasectomy Vasectomy blocks sperm from traveling through the vas deferens, preventing sperm from mixing into semen No glands or organs are removed Effectiveness: 99%+ Considered irreversible

28. Sterilization: Vasectomy Vas deferens must be isolated Similar to tubal ligation, the vas deferens can be cut and tied, clamped, cauterized, no scalpel technique Another form of contraception must be used for a few months

29. Sterilization: Vasectomy Cost: $350-1000 (plannedparenthood.org) Side effects – Bruising – Sensitivity/pain for up to a few weeks past the procedure – Sperm leaking from tubes may lead to small lump (usually clears up on its own) – Antibodies to sperm may develop, reducing chances of fertility in a reversal

30. Vasectomy Complications Rare Usually associated with infection (fever, pus/blood from incision site, swelling, pain) Ends of tubes may grow back together (very rare) Decreased sexual desire (4 out of 1000 cases per Planned Parenthood) - no apparent physical cause

31. Sterilization: Vasectomy Animation (BUPA Health via YouTube, 2:36) Animation Open-ended (no scalpel) vasectomy (medicalvideos.us) Video (vasectomymedical.com) Video

32. Sterilization: Tubal Ligation Surgical technique Close fallopian tubes, preventing egg from traveling to uterus, preventing sperm from reaching egg Neither organs nor glands are removed Effectiveness: 99%+ Considered irreversible

33. Sterilization: Tubal Ligation Tubal sterilization: – Tubes can be tied and cut (Pomeroy technique) Tubes can be tied and cut – Tubes can be cauterized Tubes can be cauterized – Tubes can be clipped, clamped Tubes can be clipped, clamped – These incision methods often performed after childbirth/abortion – Animation (SMART imagebase) Animation

34. Sterilization: Tubal Ligation Cost: $1000-3000 Side effects: thought by many to be rare; hormonal imbalance may lead to increased menstrual bleeding, cramping; adhesions Complications: infection, internal bleeding, ectopic pregnancy Before/after photos (private Flickr account) Before/after photos

35. Sterilization: Implants Non-incision method – No general anesthesia – Under an hour Coils inserted into fallopian tubes In following months, coils and tissue grow together, forming barrier to prevent sperm from reaching egg

36. Sterilization: Implants Side effects: expulsion of coil inserts, risk for ectopic pregnancy, cramping, menstrual changes, nausea/vomiting Demo (Essure) Demo Late November: reports of problems coming to a head: headaches, pelvic pain, chronic fatigue, coils moving to other parts of body and hurting tissue, others “Pre-market approval” = exempt from lawsuits

38. Fertility Awareness Methods

39. Temperature Method Females track temperature every morning Look for slight drop in temperature occurring immediately before ovulation At ovulation, temperature increases Temperature changes are small Look for trends, expect daily fluctuations Image source: Public domain, Wikimedia Commons

40. Temperature Method Use basal thermometer – Smaller scale (1/10 degree) Chart temperature for at least three months before relying on method Safe sex time begins 72 hours after temperature has risen, remains until temperature begins to drop Source: Dr. Sacha Elliott, ND

41. Temperature Method Day 10: 98.5Day 17: 98.8 Day 11: 98.4Day 18: 99.0 Day 12: 98.4Day 19: 98.7 Day 13: 98.1Day 20: 98.7 Day 14: 97.9Day 21: 98.8 Day 15: 98.0Day 22: 98.6 Day 16: 97.5Day 23: 98.5

42. Cervical Mucus Method Tracking the variation in mucus consistency throughout cycle Cervical mucus begins a few days after menstruation As mucus production increases, it ’ s yellow or white in color & cloudy, sticky Will become wet, clear Clear, slippery mucus = most fertile Mucus production decreases, cloudy & sticky

43. Cervical Mucus Method Tracking Your Cervical Mucus, Babycenter.com Tracking Your Cervical Mucus “ Safe days ” = begin after slippery mucus decreases, continue into cloudy & tacky, and especially dry days Short cycles = mucus may be hidden in menstrual flow

44. Calendar Method Predicting “ safe ” and “ unsafe ” days based on length of monthly cycles Can use traditional calendar, software, phone app, web tools

45. Calendar Method Count length of menstrual cycle – Day #1 = first day of menses – Last day = day before menses returns – Eight cycles are recommended before relying on this method (Planned Parenthood) – First fertile day = shortest cycle minus 18 – Last fertile day = longest cycle minus 11

46. Calendar Method Cycle 1: 24Cycle 2: 27 Cycle 3: 25Cycle 4: 28 Cycle 5: 25Cycle 6: 27 Cycle 7: 29Cycle 8: 25 Shortest day: 24 Longest day: 29 Unsafe days: #6-18

56. Intrauterine Contraceptives (IUC ’ s) IUC ’ s are made of flexible plastic, available only through prescription Three types – ParaGard (copper) – Mirena (hormone) – Skyla (hormone)

57. IUC ’ s: ParaGard ParaGard contains copper Copper prevents sperm from fertilizing an ovum Copper also makes implantation of fertilized ovum difficult Amount of copper released is less than needed in daily diet Copper intolerance or insensitivity would preclude use of ParaGard

58. IUC ’ s: Paragard Requires insertion into uterus by healthcare provider – Takes only a few minutes – Insertion may cause cramping, dizziness Once inserted, may remain in place for ten years – Patient should not feel IUD Since no hormones present, monthly cycle should remain unchanged Effectiveness: 99%+ against pregnancy Requires monthly checking for IUD slippage

59. IUC ’ s: ParaGard Side effects: heavier and longer periods, cramping, spotting in between periods – May lessen after a few months on ParaGard Complication risks: pelvic inflammatory disease shortly after insertion, perforation of uterus, expulsion Copper may provide protective benefit against endometrial cancer Cost: $0-1000 (Planned Parenthood)

60. IUC ’ s: Mirena Progestin-only intrauterine contraceptive Lasts for five years Mirena: – Prevents sperm from fertilizing ovum – Prevents release of egg – Changes uterine lining

61. IUC ’ s: Mirena Insertion: Similar to ParaGard Effectiveness: 99%+ against pregnancy Cost: $0-400 (Consumer Reports) Side effects: Abdominal cramping (10% of users during first few months), acne, breast tenderness, headache, mood changes, back pain – May lessen after a few months – As use continues, less menstrual bleeding Complication effects: ovarian cysts, pelvic inflammatory disease shortly after insertion, perforation of uterus, expulsion

62. IUC: Skyla FDA approved in 2013 Hormone Smaller than Mirena Lasts three years instead of five Marketed to women who have not had kids – Mirena marketed to women with child (research done only on this group) – IUC’s appropriate for all women
