3-6 days

5

Pharm effects of progestins as contraceptives

1. Inhibits ovulation by suppressing fxn of HPOvarian axis
2. Modified mid-cycle surges of LH and FSH
3. Diminishes ovarian hormone production
4. Reduces activity of cilia
5. Produces endometrial changes unfavorable to embryo implantation
6. Thickens cervical mucus to impede sperm transit

6

Depo provera injection MOA

big dose
works at all levels to suppress ovulation
- may see delay in return to fertility

7

Progestin only implant

systemic absorption

1. inhibit ovulation
2. thickens cervical mucus
3. Decrease tubal motility
4. Atrophic endometrium

8

Levonorgestrel IUD

Inhibits ovulation
2. decrease tubal motility
3. Atrophic endomet
4. THickens cervical mucus!!!!

9

Combined hormonal contraception

1. Inhibits ovulation
2. Decrease tubal motlity
4. thickens mucus

*more forgiveness

10

Methods that work the best?

Where pts dont have to do anything
1. IUD
2. Female sterilization
3. Copper IUD

11

EMergency contraception

same as BC but higher dose

1. Disrupt follicular development
2. Block LH surge

4. Disrupts luteal phase

- NOT SAME as abortion pill

12

Emergency contraception that works well for obese women

Ella
- ulipristal acetate
*progesterone receptor modulator

13

Effects of estrogen

Contraception benefit
1. Helps stabilize uterine lining-less breakthrough bleeding
2. Added suppression of FSH less follicle development

Noncontraceptive benefits
1. Reduces SHBG --> less male effects (acne)
2. Reduces ovarian cancer, endometrial, colon cancer risk

14

Physiologic risk of estrogen

1. Estrogen increases clotting factors
- II, VII, X, XII, VIII, fibrinogen
2. Shift towards thrombus formation and prevention of clot dissolution
3. Great risk of venous and arterial clot formation

15

Who should avoid combined hormonal contraception

1. smokers over 35
2. CAD / HD
3. Risk of cloths
4. Uncontrolled HTN
