Chemical methods
Birth Control Pill
 |
The most common type of birth control
pill uses the hormones
estrogen and progestin to prevent ovulation. When taken on schedule, the pill is highly effective. About 8% of typical users get pregnant, including those who miss doses. Like all hormonal contraceptives, the pill requires a prescription. |
Spermicide
 |
Spermicide contains a chemical that kills sperm.
It comes in the form of foam, jelly, cream, or film that is placed inside the vagina before sex. |
Mechanical methods
Male Condom
 |
The latex condom is the classic barrier
method.
It prevents sperm from entering the woman’s body,
protecting against
pregnancy and STDs.
Of couples who rely only on male condoms,
15% get pregnant
in a year.
|
Female Condom
 |
The female condom is a thin plastic
pouch that lines the vagina
and can be put in place up to 8 hours before sex.
Users grasp a flexible, plastic ring at the closed end to guide it into
position.
It's somewhat less effective than the male condom.
|
Diaphragm
 | ||
The diaphragm is a rubber
dome that is placed
over the cervix before sex.
IUD
|
Surgical methods
Tubal Ligation
 |
A surgeon closes off the fallopian tubes, preventing eggs
from making their journey out of the ovaries. |
Vasectomy
 |
Besides condoms, a vasectomy is the
only birth control option available to men. It involves surgically closing the
vas deferens – the tubes that
carry sperm from the testes, through the
reproductive system.
This prevents the release of sperm but doesn’t interfere
with ejaculation.
|
Least Effective Methods
 |
Without using any form of birth
control,
85% of sexually active couples will get pregnant within a year.
Even
the least effective birth control options
reduce that number considerably.

There is a mistake where it says contraceptive pills prevent pregnancy - surely oestrogen and progesterone can't prevent it because they are the causes of pregnancy.
ReplyDelete"Birth control pills prevent pregnancy through several mechanisms, mainly by stopping ovulation. If no egg is released, there is nothing to be fertilized by sperm, and the woman cannot get pregnant. Most birth control pills contain synthetic forms of two female hormones: estrogen and progestin. These synthetic hormones stabilize a woman's natural hormone levels, and prevent estrogen from peaking mid-cycle. Without the estrogen bump, the pituitary gland does not release other hormones that normally cause the ovaries to release mature eggs.".
