  3. 3. Contraception Definition  Contraception generally implies the prevention of pregnancy following sexual intercourse by  inhibiting viable sperm from coming into contact with a mature ovum  by preventing a fertilized ovum from successfully implanting in the endometrium.
  4. 4. Commonly used methods  Reversible contraception  Oral contraceptives  Long acting injectable or implantable progestins  Combined estrogen patch  Condoms, spermicides, diaphragms, withdrawal, periodic abstinence, and IUD’s
  5. 5. Properties of Contraceptive Desired by Patients  Highly effective  Prolonged duration of action  Rapidly reversible  Privacy of Use  Protection against STD’s  Easily accessible
  6. 6. Oral Contraceptives  Introduced to the US in 1960  Works through the manipulation of normal physiologic feedback mechanisms of the menstrual cycle by varying amounts of estrogen and/or progestin.  Proven to be a very effective and popular method of birth control.
  7. 7. The Pill Advantages  Easy to use  Dependable  No additional appliances  Can regulate menstrual flow and decrease cramps and other symptoms of menses
  8. 8. Missed pills  Missed 1 day:ASAP and next pill at regular time  Missed 2 days: 2 when she remembers, 2 the next day, use back up until her next period  More than 2 days: Restart and use a back up method
  9. 9. Contraindications  History of cerebrovascular disease  Uncontrolled hypertension  DVT or PE  Migraines worsened by estrogen  Estrogen dependent neoplasm  Ischemic heart disease  IDDM w/ complications  Breast Cancer  Impaired liver function  Smokers>35y/o
  10. 10. Estrogen  Inhibits ovulation by suppressing of pituitary release of FSH/LH (negative feedback)  Inhibits implantation by altering secretions within the uterus  Accelerates ovum transport  Induction of luteolysis: degeneration of corpus luteum prevents normal implantation and placental attachment
  11. 11. Estrogenic Side Effects  Nausea  Weight gain  Fluid retention  Pulmonary emboli  Hypertension  Thromboembolic complications  Stroke  Increase in bile cholesterol
  12. 12. Progesterone  Inhibits ovulation by disruption of HPO function and by modification of mid-cycle FSH/LH surge  Inhibits implantation by suppressing the endometrium  Production of thick cervical mucus  Prevention of sperm penetration  Slows ovum transport
  13. 13. Progestin Side Effects  Increased appetite  Depression, fatigue, lethargy  Acne, oily skin  Hirsutism  Headache  Weight gain  Decreased libido  Increased LDL, decreased HDL  Hypertension
  14. 14. Noncontraceptive benefits  Relief from menstruation- related problems  Decreased cramps  Decreased ovulatory pain  Decreased menstrual blood loss  Disease prevention  Ovarian and endometrial cancer  Ovarian cysts  Ectopic pregnancy  Pelvic inflammatory disease  Benign breast disease
  15. 15. Contraindications  History of cerebrovascular disease  Uncontrolled hypertension  DVT or PE  Migraines worsened by estrogen  Estrogen dependent neoplasm  Ischemic heart disease  IDDM w/ complications  Breast Cancer  Impaired liver function  Smokers>35y/o
  16. 16. Transdermal Contraception  Ortho Evra  Norelgestromin and Ethinyl Estradiol  Similar to OC’s  Not recommended in patients >198lbs, less effective  Applied every 7 days for 3 weeks followed by patch free week  Convenience, increased compliance
  17. 17. Ortho Evra  If a patch comes off????  <24 hours  Reapply  use a new patch  >24 hours  apply a new patch  use this day as the new patch change day  use a back up method until 7 consecutive days  Patient Education  Similar side effects to OC’s  Same incidence of drug interactions  Apply to abdomen, buttock, upper outer arm, and upper torso  Back up method should be used until after the first 7 days of consecutive administration
  18. 18. Implants  Progestin only (Norplant)  Prevents ovulation  More effective than the Pill
  19. 19. Implant  Advantages  Convenience  Eliminate user error  No menses or very light  Decreased cramping
  20. 20. Implant  Problems • Difficulty in removing  Side effects •Similar to the pill •Changes in menstrual bleeding •Headaches  Side effects •wt. gain •Acne •breast tenderness •hair growth •ovarian cysts

  23. 23. Depo-Provera  Advantages  Highly effective 99.7%  Increased compliance  Amennorrhea  Reduced risk of anemia  Decreased menstrual cramps/pain  No drug interactions w/ anticonvulsants  Disadvantages  Break through bleeding  Weight gain  Headache  Depression  Decreased HDL  Risk of ectopic pregnancy  Contraception reversible in 4- 13months
  24. 24. Barrier Methods  The condom  Female condom  Diaphragm  Cervical cap  Sponge
  25. 25. IUD  Intrauterine device  Copper and plastic (Copper T-380A) 10 years  Plastic and Progesterone (progestasert IUD) 1 year  90-96 % effective in use  Increased risk of PID
  26. 26. Spermicides  Nonoxynol-9  Use in combination with barrier methods of contraception  Foam  gel  Film  Creams, jellies and suppositories
  27. 27. Fertility Awareness Methods  Calendar or rhythm method  Midway in cycle  Basal body temperature (BBT) method  Increase in body temperature  Cervical Mucous Method  Clear slippery mucous  Symptothermal method  Combination of BBT and Cervical Mucous methods
