Contraception Induced abortion
3
How Pregnancy (Conception) Occurs
4
Contraception mechanism Prevents ovulation Thickens mucus at the cervix so sperm cannot pass through Changes the environment of the uterus and fallopian tubes to prevent fertilization and to prevent implantation if fertilization occurs Block sperm from reaching the egg
5
Contraception mechanism
6
controception methods female – IUD – Hormonal contraception – Emergency contraceptive – External contraception femshield spermicide – Safe period contraception – Contraceptive vaccines – sterilization male – condom – sterilization

Contraceptive methods
9
Map of the use of various of contraception in China & developed countries Oral contraceptive CondomSpermicide Others Male sterilization Subcutaneous implantation IUD Female sterilization Vaginal barrier IUD Condom Injection/subcutaneous implantation Others Oral contraceptive Sterilization United Nations Department of Economic and Social Affairs Population Division: World contraceptive Use 2003
10
IUD ( intrauterine device ) Types of IUD Inertia IUD ( first generation ) Active IUD ( second generation ) – Copper-containing IUD ( include nonsupport IUD ) – Medicine-containing IUD LNG-IUD Indomethacin-IUD
11
IUD mechanism of action Killing sperm & embryo poison Interference implantation LNG mechanism
12
The active ingredient: Levonorgestrel Thickening of the cervical mucus It prevents thickening of the womb lining Prevent ovulation Mirena®

16
IUD side effect and complication Side effect – Heavy bleeding – Prolonged menstruation – Spotting – Discharge increasing – Abdominal pain Complication – Ectopic – Embedded meal – Crack – Down – Fall off – Pregnancy with IUD
17
Contraception methods – IUD – Hormonal – Others Emergency contraception External use contraceptive
18
Hormonal contraception Contraceptive mechanism – Suppression of ovulation – Changes in the cervical mucus properties – Morphologic and functional changes of endometrial – Change the function of fallopian tube
19
Hormonal contraception --Types Oral contraceptives long-acting reversible contraceptives (LARC) – Long-acting contraceptive needle (DMPA) – Sustained release contraceptives (Norplant 、 Implanol) You will be given a local anesthetic and asked to lie on your back, with your non- dominant arm slightly bent at the elbow and turned outwards. The skin is stretched and a needle containing the implant is inserted directly under, and parallel to, the skin on the inside of your upper arm. The implant will then remain under the skin when the needle is withdrawn
20
Available options for LARC Injection, effective up to 12 weeks Levonorgestrel (LNG) intrauterine system, effective for up to 5 years Copper intrauterine device (IUD), effective for up to 10 years Implants, effective for up to 3-7 years
21
Hormonal contraception –Oral contraceptives – Short-acting – long-term – combination oral contraceptive – Three-phase pills – Four-phase pills
22
Reduce the changes of coagulation system – To reduce the incidence of thrombosis To reduce the subjective side effects – nausea – Vomiting – breast tenderness Increased tolerance Development trend of OC T he lowest estrogen content of oral contraceptives Gradually reduce the dose of estrogen
23
Contraindications to hormone contraception Cardiovascular disease, thrombosis Acute / chronic liver / nephritis Malignant neoplasms, precancerous lesions Endocrine disease Smoking Mental disease Recurrent severe migraine
24
Side effects of hormonal contraception Early pregnancy reaction Menstrual disorders Body weight change Skin problems Headache, diplopia, breast swelling
25
Safety of hormonal contraception The two panic: – In 1983 the breast cancer – In 1995 the venous thrombosis Metabolism Cardiovascular Coagulation Tumor Progeny Oral contraceptive non contraceptive benefits Treatment of bleeding and control cycle The treatment of endometriosis Improvement of premenstrual syndrome Reducing osteoporosis
26
Contraception methods – IUD – Hormonal – Others Emergency contraception External use contraceptive
27
What is emergency contraception? Emergency contraception is a way to prevent pregnancy if: – Sex without using birth control – Birth control method failed forgot to take pill or get shot the condom broke or came off diaphragm slipped – Be raped
28
What are the types of emergency contraception? Pills – work well – don't cost a lot – usually easy to get Copper intrauterine device (IUD). – works very well – but it has to be inserted by a doctor
29
How does it work? Emergency contraception pills work by –preventing ovulation –preventing fertilization –preventing implantation –96% effective The copper IUD may work by –killing sperm –preventing fertilization –preventing implantation –99% effective
30
Emergency contraception may cause some side effects – spotting or mild symptoms like those of birth control pills – nausea or vomiting – sore breasts, fatigue, headache, belly pain, or dizziness – An IUD may cause cramping and bleeding during the first few days after insertion Does it cause side effects?
31
Emergency contraception pills won't protect you for the rest of your cycle. Use your regular method of birth control, or use condoms. Unless you get an IUD, emergency contraception does not take the place of regular birth control. Find a good method of birth control you can use every time you have sex. Emergency contraception does not prevent sexually transmitted infections (STIs). What else should you think about?
32
MethodHow it prevents pregnancy Barrier methods Block sperm from reaching the egg Some are used with spermicides, which kill sperm. Fertility awareness (natural family planning) Identifies the time during a woman's cycle when she is most likely to become pregnant (fertile). An additional method or abstinence should be used during this time of fertility. Permanent birth control (sterilization) Men: Vasectomy blocks the release of sperm. Women: Tubal ligation surgery or tubal implants block the movement of an egg through the fallopian tube, preventing fertilization.

35
Contraception Induced abortion
36
Termination of early pregnancy – Artificial abortion Vacuum aspiration<10w – Medical abortion
37
Common complications Complication Uterine perforation and visceral injury Bleeding in operation Induced Abortion syndrome Incomplete abortion Uterine hemorrhage Infection Miss-suction or leakage Cervical and intrauterine adhesions Regret syndrome (long-term) Regret syndrome (long-term)
38
Medical abortion Is a kind of non operation of artificial abortion Could reduce the fear and pain on the operation of women Long bleeding time and the potential risk of major bleeding Is the only remedy for contraception failure Not a contraceptive method vaginal bleeding Vacuum abortion <7 days Medical abortion 14-15 days 19.2% complete abortion >21 days 1.5% emergency curettage 0.16%blood transfusion
39
Medical contraindications Mifepristone: – endocrine disease – history of ICP – blood disease – history of thrombosis Prostaglandin contraindications: – cardiovascular disease – Glaucoma – Asthma – Epilepsy – colitis Other: – allergic constitution – IUD with pregnancy – ectopic pregnancy – hyperemesis gravidarum – medication (anti tuberculosis, epilepsy, anti depression, anti prostaglandin drug)
