I. MALE CONDOMS
II. FEMALE CONDOMS
III. DIAPHRAGM
IV. CERVICAL CAP
V. SPERMICIDE
BARRIER METHODS
8. Male condom
What? A thin covering that one unroll over an erect
penis. Made of latex, polyurethane, or animal
membrane (don’t protect against STDs).
How? Put on before any genital contact. At

Individual fitting is required.
Effectiveness: 82-94%

put in 10 minutes before intercourse.
Notes: Key ingredient is Nonoxynol9.
Neither partner should notice
spermicide.
Effectiveness: 72-91%
13. Chemicals similar to hormones stops the release of egg; weaken the
sperm; change cervical mucus and uterine lining; and reduce
implantation.
The Pill
The Patch
Vaginal Ring
The Shot
Implant
Hormonal Methods

A small incision is made in the
abdomen to access the fallopian
tubes. Fallopian tubes are
blocked, burned, or clipped shut
to prevent the egg from
traveling through the tubes
Recovery usually takes 4-6
days
