barrier methods, spermicides, intrauterine devices, and hormonal methods
what are examples of:

- spermicides?
- Intrauterine devices?
- hormonal methods?
- barrier methods: condom (male and internal condom) and diaphragm
- spermicides - nonoxynol -9 (N-9)
- intrauterine devices
- hormonal methods: the pill, the patch (xulane) , the Depo Provera shot, the Nuvaring, the implant (nexplanon)
what are some determinants of use for birthcontrol?
- knowledge and familiarity
- high income
- cohabitation
- religious reasons
what age group for women are at the highest risk of pregnancy while not using birth control? which group is at the lowest?
highest = 15-19 years old
lowest = 40-44 years old
what are the three highest used forms of birthcontrol in college students?
the male condom, the pill, and withdrawl
what is the difference between abstinence and celibacy?
abstinence - is the absence of genital contact that lead to pregnancy
celibacy - the avoidance of all forms of sexual activity and a commitment to maintain this lifestyle
which contraceptive method remains one of the most popular in the US? what are some other methods that are popular?
- the pill is the most popular
- female sterilization and condoms
what is the difference between typical use and perfect use when it comes to birth control? which one is the better one to help decide the best birth control method?
typical use- the way a birth control method is actually used including incorrectly, non use, and inconsistent use in people who report using birth control methods
(Typical use is the better one to help decide which method you want to use)
perfect use - following the directions of the birth control method exactly and rates are estimated during clinical trials
who is widely regarded as the founder of the modern birth control movement?
Margaret Sanger
- she opened up an illegal clinic to women to give out diaphragms so they could have better control over when they want to conceive
which birth control method is known as corpitus interruptus? what happens in this method?
-the withdrawl method
- the penis is completely removed form the vagina before ejaculation and away from the external genitalia to prevent sperm from entering and fertilizing the egg
what percent of contraceptive users use the withdrawl method? what is the failure rate?
- 12% use this method
- 20% failure rate
what hormones are used in the pill? what can the pill do?
- synthetic estrogen and/or progesterone
- the pill can:
- thicken the cervical mucus to prevent sperm from penetrating into the vagina canal
- thin the uterine lining to make it harder for a fertilized egg (ovum) to implant
- suppress ovulation 90-95% of the time
- slows the rate of ovum transport
-disrupts transport of fertilized egg
what are the different types of pills? which of the type of pills is the most effective?
- the different types of pills include:
1) combination pills: contain estrogen, different amount of progestin, and synthetic progesterone (COMBINATION PILLS ARE THE MOST EFFECTIVE) - perfect use rate is 95%, typical use rate is 91%
2) progestin only pills (POP’s or minipills): these are slightly less effective that combination pills and must be taken precisely
- minipills are best used for women who cannot take combination pills with estrogen (eg. women who are breast feeding, have breast cancer, have liver disease, and have had weight loss surgery)
when is the pill not effective? what are the advantages and disadvantages of the pill

how does progestin work?
prevents ovulation and thickens the cervical mucus which keeps the sperm from reaching the egg

False. it is safe it acts as an alternative to use estrogen
what method of birth control is called xulane? how long do you need to use this method? what can make this patch less effective?
what is its PU rate? what is its TU rate?
- the birth control patch: releases estrogen and progestin to prevent against pregnancy for one month
- you use this patch for three consecutive weeks then for one week you do not wear it for menstruation ( place it on butt, back, stomach, or upper arm)
- some antibiotics, HIV medications, and antifungal griseofulvin can make this patch less effective

define the vaginal ring? what does it do? what are the different types? what types of lubricants cannot be used with this contraceptive method?
- small flexible ring inserted into the vagina once for 28 days (kept in place for 21 days then taken out for a week to allow for withdrawl bleeding)
- it releases estrogen and progestin that prevents ovulation and thickens the cervical mucus
- the different types are:
1) nuvaring- must be replaced after three weeks
2) annovera - can be used for up to a year ) can be cleaned and reuse the same ring every month) - oil and silicone based lubricants cannot be used with this type
3) eluryng

Pu rate: 99%, TU rate is 91%
ADAVNTAGES:

Pu rate: 99% and TU rate is 98%
what is the most common type of IUD used. what does it do? how long does it protect against pregnancy for?
copper based (paragard)
- releases copper ions that trigger sterile inflammatory response which disable sperm and makes it difficult for sperm to meet and fertilize the egg
- protects against pregnancy for up to 10 years
what do hormonal iuds do? how long can these protect against pregnancy?
- hormonal iuds release progestin and this thickens the cervical mucus and thins the uterine lining to prevent against fertilization (this creates a hostile environment where the sperm cannot reach the egg)
- these can protect from pregnancy for 3 - 6 years depending on the device
what are the advantages and disadvantages of the IUD?
ADVANTAGES
-paragard can act as an emergency contraceptive if inserted five days after unprotected sex
