Couple looking for advice on contraceptive strategies
Upstream causes
Not wanting another child
long term effects of birth control
Possible need for a more permanent contraceptive device
Concerned about long term birth control use
Downstream effects
3 Worst Options

3 Best Options
Intrauterine device
Pregnancy occurs less than 1 in 100
No need for other contraceptive measures
Used as long term
Surgical sterilization/vasectomy
Safe form of contraception
100 percent effective
No hormonal changes
May lower risk for ovarian cancer
Condoms
Inexpensive
Offers best protection from STDs and HIV
No added hormones
Background
Anatomy of male reproductive system
Penis
Acts as a conduit for urine to leave the body
Has erectile and ejaculatory functions
Scrotum
Sac of skin and superficial fascia that hangs outside the abdominopelvic cavity at the root of the penis
Contains the testicles as well as many nerves and blood vessels
Has a protective function
Acts as a climate control system for the testes for normal sperm development
Testes
Produce gametes and secrete hormones
Epididymis
Transports and stores sperm cells that are produced in the testes
Brings the sperm to maturity
Vas deferens
Transports mature sperm to the urethra in preparation for ejaculation
Prostate
Secrete prostate fluid
Muscles help propel seminal fluid into the urethra during ejaculation
Seminal vesicles
Store and produce the majority of the fluid that makes up semen
Anatomy of female reproductive system
Vagina
Thin walled tube that lies between the bladder and the rectum.
Provides a passageway for delivery of an infant and for menstrual flow.
Female organ of copulation
Uterus
Nurturing the fertilized ovum that develops into the fetus
Holding fetus until the baby is mature enough for birth
Fallopian tubes
Transport the ova from the ovary to the uterus each month.
Transport fertilized egg to uterus for implantation
Cervix
Lower most part of the uterus and is made up of strong muscles
Allows flow of menstrual blood from the uterus into the vagina
Directs sperm into the uterus during intercourse
Ovary
Produce and releases eggs into the female reproductive tract at the mid-point of each menstrual cycle
Produce female hormones estrogen and progesterone
Mons Pubis
Area of fatty tissue that covers the pubic bone
Secretes pheromones responsible for sexual attraction
Labia majora
Pair of rounded folds of skin and adipose that are part of the external female genitalia
Covers and protects the inner more delicate and sensitive structures of the vulva, labia minora, clitoris, urinary orifice, and vaginal orifice
Labia Minora
A pair of thin cutaneous folds that form part of the vulva
Function as protective structures that surround the clitoris, urinary orifice, and vaginal orifice
Bartholin's glands
Secrete mucus to provide vaginal lubrication during sexual arousal
Clitoris
No functions in reproduction but is the main pleasure center for females during intercourse
Uterine/Ovarian cycle
Luteal phase
Days 14-28
Period during which the corpus luteum is active
After ovulation, the ruptured follicle collapses and the antrum fills with clotted blood
Coropus hemorrhagicum is eventually absorbed and the remaining granulosa cells enlarge
Follicular phase
Period when a cohort of vesicular follicles begins to secrete increasing amounts of estrogens and one of these follicles is selected as the dominant follicle.
Lasts from the first to the 14th day of ovarian cycle, which ovulation typically occurs
Many large vesicular follicles are growing in the ovary during the phase
Rising levels of FSH
Major contraceptive methods
Barrier methods
Male condoms
Thin sheath that covers the penis to collect sperm and prevents sperm from entering the woman's vagina
Reduce the risk of STDs if using latex or polyurethane condoms
Lambskin condoms do not prevent STDs
Disposed after a single use
Female condoms
Thin flexible plastic pouches
Portion of condom is inserted into a woman's vagina before intercourse
Prevents sperm from entering the uterus
Reduces the risk of STDs
Disposed after a single use
Contraceptive sponges
Soft, disposable, spermicide-filled foam sponges
Inserted into the vagina before intercourse
Blocks sperm from entering the uterus and kills the sperm cells
Sponge should be left in place for at least 6 hours after intercourse and removed after 30 hours after intercourse
Spermicide
Can kill sperm cells
Can be used alone or with a diaphragm or cervical cap
Comes in the form of jelly, cream, suppository, and film
Should be inserted into vagina close to the uterus no more than 30 minutes prior to intercourse and left in place for 6 to 8 hours after intercourse
Can cause allergic reactions
Emergency contraception
Copper IUD
Most effective emergency contraception
Can be inserted within 120 hours of unprotected intercourse
Nearly 100% effective at preventing pregnancy
Can cause heavier or longer periods, spotting between periods, and irregular periods
Pills
Hormonal pills
Take in either single or two doses 12 hours apart
Intended to use in the event of unprotected intercourse
If taken prior to ovulation, pills can delay or inhibit ovulation for at least 5 days to allow for sperm to become inactive
Thickens cervical mucus and may interfere with sperm function
Not to be used as a regular contraceptive method
Can cause nausea, vomiting, dizziness, fatigue, headache, breast tenderness, bleeding between periods or heavier menstrual bleeding, lower abdominal pain or cramps
Hormonal methods
Injectables, pills, patches, and rings
Injectable birth control involves injection of a progestin.
Injections every 3 months
Can cause loss of bone density
Patients should eat a diet rich in calcium and vitamin D or take vitamin supplements
Pill must be taken daily
Thickens cervical mucus
Contains a synthetic estrogen and a progestin
Inhibits ovulation
Can cause nausea, weight gain, sore or swollen breasts, spotting between periods, lighter periods, and mood changes
Patch
Thin, plastic patch that sticks to the skin and releases hormones through the skin into the bloodstream
Can be placed on the lower abdomen, buttocks, outer arm, or upper body
New patch every 3 weeks
No patch used on 4th week to enable menstruation
Can increased risk of blood-clotting problems, heart attack, stroke, liver cancer, gallbladder disease, and high blood pressure
Ring
Thin, flexible and approximately 2 inches in diameter
Delivers a combo of ethinyl estradiol and a progestin
The ring is inserted into vagina
Continuously releases hormones for 3 weeks
No ring inserted on 4th week and reinserts a new ring after 7 days
Not recommended for women with high blood pressure, heart disease, or certain types of cancer
Can cause a decreased sex drive, headache, mood changes, vaginal irritation or discharge, pain in cervix, menstrual cramps, breast pain or tenderness, acne, weight gain, or stomach pain
Sterilization
Permanent form of birth control
Prevents a woman from getting pregnant or prevents a man from releasing sperm
Tubal ligation
Fallopian tubes are either cur, tied, or sealed
Blocks the path between the ovaries and the uterus
Sperm are unable to reach the egg to fertilize it and the egg cannot reach the uterus
Vasectomy
Surgical procedure that curs, closes, or blocks the vas deferens
Blocks the path between the testes and urethra
Sperm cannot leave the testes and cannot reach the egg
Can take up to 3 months to be fully effective
Backup method of contraception should be used until tests confirm that there is no sperm in semen
Long acting reversible Contraception
IUD (Intrauterine device)
Hormonal IUD
Releases a progestin hormone(levonorgestrel) into the uterus
Causes thickening of the cervical mucus
Inhibits sperm from reaching or fertilizing the egg
Thins uterine lining
May prevent ovaries from releasing eggs
Copper IUD
Prevents sperm from reaching and fertilizing the egg
May prevent the egg from attaching in the womb
If fertilization does occur, the device prevents implanting into the lining of the uterus
Implants
Implantable rods inserted under the skin of a women in the upper arm
Releases progestin and can remain implanted for us to 5 years
