Risk and Responsibility
If intercourse occurs the day before ovulation, the chance of pregnancy is about 30%.
If intercourse occurs the day of ovulation, the chance of pregnancy is about 15%.
Over the course of one year, couples who do not use contraception have a 90% chance of pregnancy.

Contraception
We use our knowledge of reproductive physiology to promote or avoid pregnancy.

Preventing Sexually Transmitted Diseases (STD’S)
Most STD’s are treatable if diagnosed early. AIDS is one exception> AIDS is FATAL. Some contraceptive methods work to help prevent
disease and pregnancy. Latex and polyurethane condoms provide barrier
protection against virus and bacterial infection: such as Herpes virus, chlamydia, gonococcus, and HIV.

Preventing Sexually Transmitted Diseases (STD’S)
Not 100% effective at preventing infection or pregnancy.
Spermicides - Chemicals that kill sperm offer protection against some STD’s, foam or film can provide extra protection.
Use of spermicides with barrier methods increase the effectiveness of both the infection and pregnancy protection of the method.

Intrauterine device (IUD) COPPER-T
MULTI LOAD
MIRENA
The progestin released by the levonorgestrel (LNg) IUD prevents fertilization by making the mucus in the cervix thick and sticky, so sperm can't get through to the uterus. The progestin and IUD change the uterine lining, preventing implantation in the rare case that fertilization occurs.
The copper in the copper IUD is toxic to sperm. It causes changes in the uterus and fallopian tubes that kill sperm

IUD:Mechanisms of Action
NOT ABORTIFACIENT!!!!!!!! Prevents Conception:
– Sperm Transport Inhibited
– Sperm Survival / Capacitation Diminished
Prevents Implantation: hCG Levels = 0
