VARIOUS METHODS OF CONTRACEPTION

Abstinence Continuous abstinence – 100% effective at pregnancy, STI prevention Periodic abstinence – Must know cycle well (see next slide)

Predicting fertility The ovum lives 1 or 2 days after it is released Sperm can live inside woman for 5-7 days Therefore, women can only get pregnant 9 days a cycle – 7 days before ovulation, – the day of ovulation – maybe the day after

Predicting Fertility Determining Ovulation So how do you know when a woman is ovulating? 1. temperature method: the temperature of the body increases by 0.4°C to 0.8°C during ovulation 2. mucous method: the mucous in the vagina becomes clear and slippery (instead of cloudy and sticky) during ovulation 3. calendar method: if you count the day that bleeding starts as day 1, day 14 is typically the day of ovulation (There’s even an iPhone app for this!)

Withdrawal Another name “Coitus interruptus” or “pulling out” When the man pulls his penis out of the vagina before he ejaculates and ejaculates outside of the vagina “Requires skill and trust” Actual effectiveness 73%

Barrier method Condoms, diaphragm, cervical cap provide a barrier to sperm Condoms: easy to obtain, few side effects, can offer some protection against STI’s Diaphragm and cervical caps: soft barriers that cover the uterus both must be used in addition to spermicide

PERMANENT METHODS OF BIRTH CONTROL

Tubal sterilization “getting your tubes tied” procedure called tubal ligation An operation that closes the fallopian tubes, (recall: where fertilization occurs) Everything else pretty much stays the same

Vasectomy Permanent birth control for men Blocks the vas deferens (recall: the tube that transfers sperm out of the testes) Does not affect sexuality – Will still ejaculate (minus sperm) – Will still become erect – Will still secrete testosterone

Before you get pregnant!!!! Be prepared- schedule a doc visit regularly Think Twice!!- parenthood – lack of sleep, changing plans because the baby is sick, enduring tantrums Eat well!!! – Folic acid ( mg/day) -through out pregnancy helps develop the brain and nervous system needed especially in 1 st Trimester Avoid harmful substance- alcohol, mercury, smoke, or illicit drugs = brain damage Get moderate exercise – walking and swimming are healthful and safe Drink your water!!!!!! (Kelly, 2010)

ABORTION

Abortions in Canada Nearly 100,000 abortions were performed in 2005; rate seems to be decreasing Most common among women in their 20s (52%) Having an abortion when the mother is younger reduces the ensuing complications Cost: $500 – $1200 There are no legal restrictions on abortion – “The state has no business in the bedrooms of the nation” –Pierre Trudeau

Legal and Social Issues (USA) Supreme court decision in famous Roe vs. Wade case made abortions legal in the US – In the first trimester the woman has the right to make the decision – In the second trimester, the state can impose rules such as where she can have the abortion – In the third trimester, abortions are illegal unless the mother’s life is at risk
