Birth Control – Temporary

Delaying Conception: Choices in Temporary Birth Control


Most women want birth control that is very reliable – yet allows the body to return to its natural cycle easily once it is discontinued.

The options for preventing conception include oral contraceptives (birth control pills), an intrauterine device (IUD), hormone shots, the contraceptive patch, vaginal ring, contraceptive implant, or an intrauterine contraceptive (IUC).

Talk with Dr. Morrison about the advantages, risks and side effects of the temporary birth control methods available to you.

New and Advanced: Mirena® and IMPLANON



Mirena®

One of the more popular choices today is the IUC Mirena®, a small, flexible device that is inserted into the uterus in only minutes during an office visit. This estrogen-free intrauterine contraceptive (IUC) delivers small amounts of levonorgestrel, a synthetic progesterone, directly to the uterus. Mirena is 99.9% effective and can be removed at any time for a quick return to fertility.

IMPLANON® Contraceptive Implant

IMPLANON® is a flexible plastic rod the size of a matchstick that is put under the skin of your arm. This implant contains a hormone called etonogestrel. IMPLANON® prevents pregnancy in several ways. The most important is by stopping the release of eggs from the ovaries. IMPLANON also changes the mucus in the cervix, which may help keep sperm from reaching the egg. In addition, IMPLANON changes the lining of your uterus, another condition which deters fertilization of an egg.

IMPLANON is more than 99 % effective and it prevents pregnancy for up to three years. Once IMPLANON is removed, the ability to become pregnant returns quickly.

Other Birth Control Options

Talk with Dr. Morrison about the benefits and risks of these birth control choices.

Oral contraceptives

Oral contraceptives, or birth control pills, contain hormones that prevent the body from ovulating. They also cause cervical mucus to thicken and create a natural barrier to sperm. Oral contraceptives contain either a combination of estrogen and progestin, or progestin only. When taken as prescribed, oral contraceptives have a 99 percent success rate.

Intrauterine Device

The intrauterine device (IUD) is a T-shaped device that is placed inside the uterus. The IUD works by altering the lining of the uterus and fallopian tubes, thereby interfering with the movement of egg and sperm and preventing fertilization. The IUD is more than 99 percent effective.

Contraceptive Hormone Shots

Birth control shots deliver synthetic hormones, via an injection, which prevent ovulation. Depending on the brand of shots, protection against pregnancy can range from 30 days to 14 weeks per shot. Birth control shots contain either a combination of estrogen and progestin, or progestin only. They are about 97 percent effective when used consistently.

Contraceptive Patch

The contraceptive patch is worn on the skin. It releases synthetic estrogen and progestin through the skin to prevent pregnancy by preventing ovulation. The contraceptive patch is changed once a week for 3 weeks. During the fourth, “patch-free” week, menstruation occurs. This pattern is repeated every month.

Vaginal Ring

The contraceptive vaginal ring is a small, transparent ring that is inserted into the vagina and worn for three weeks. The ring slowly releases estrogen and progesterone into the body to prevent ovulation. These hormones also cause cervical mucus to thicken and create a natural sperm barrier. The ring is worn for three consecutive weeks before it is removed for one week. Menstruation occurs during the week the ring is not worn.
