Contraceptive injection progestin

Just like oral contraceptives, birth control injections work at suppressing ovulation. With a success rate of nearly 99.7 %, these hormonal injections are effective for 12 weeks. The hormonal birth control shots are also known as DMPA - depot medroxyprogesteroneacetate.

It is effective for women who cannot take estrogen. There is lesser menstrual cramping as well as lesser chance of anemia when on such birth control injections. Besides, it decreases the risk of endometrial cancer, ovarian cancer and pelvic inflammatory disease. Contraceptive shots can be used while breastfeeding.

Progestin injection is not recommended for long-term use since it has some side effects. Irregular bleeding is a common side effect. Some women complain of longer or heavier menstrual bleeding. Some women who are on birth control injections also experience depression, skin rash, weight gain and nausea. Hair loss or increased hair growth on the face and body can also result from use of birth control shots. It is noticed that some women experience decreased sexual drive. Some studies have shown that women using contraceptive injections may experience loss of bone density that may increase their risk of osteoporosis.

Therefore women who are on birth control injections are advised to take plenty of calcium and keep up an exercise regimen. Women taking medication for Cushing's syndrome may not receive adequate birth control protection from this injection. Birth control shots do not offer any protection against sexually transmitted infections. Sometimes, there is a slight delay of return to fertility in some women.

Birth control shots are not recommended for women who want to become pregnant in the near future or those who have unexplained vaginal bleeding. Women who are diabetic or have recently suffered from liver disease are allowed to use injectable birth control shots only under close medical supervision.

Intrauterine Device IUD

IUD - Intra Uterine Device is a birth control measure that prevents fertilization. The IUD is inserted inside a woman's uterus to prevent pregnancy. This is a highly reliable form of birth control - nearly 150 million women use it worldwide. The IUD prevents pregnancy by either interfering with the movement of sperm to fertilize the egg or by preventing implantation of a fertilized egg.

Modern IUDs resemble a matchstick and have a T shaped bar across the top. When inserted into the uterus, the arms of the T open out and extend horizontally across the uterus. This birth control measure is nearly 11/2 inches long and is usually made of copper and plastic. The Copper IUDs can be kept in place for nearly 10 years and have a low failure rate. The progesterone- based IUDs release a form of progesterone that makes the mucus in the uterus sticky thereby preventing sperm from getting to the uterus.

The IUD offers a woman birth control without affecting the hormone levels in her body. Another advantage is that fertility is restored as soon as the IUD is removed. The IUD is a cost effective method of preventing pregnancy. It can be safely used during breast-feeding and does not involve routine check ups. IUDs however do not provide any protection against sexually transmitted diseases. An IUD is a preferred form of birth control when you are married or have only one sexual partner. Women who have had a history of ectopic pregnancies must not use IUD as a birth control measure. It is also not advised for women with uterine abnormalities, heavy bleeding and fibroids. No woman must get an IUD inserted unless she is certain that she is not pregnant. IUDs are not advised for teenagers and women who have never had children.

Side effects of IUDs may be an increased risk of PID - Pelvic Inflammatory Disease. Some women complain of heavier periods on account of the IUD. Spotting between periods is another complaint by women who have opted for IUD. A rare possibility is of the IUD perforating the uterus. In about 5% of the cases, the IUD is expelled from the uterus into the vagina in the first few months of use.

Contraceptive pill

Birth control pills are oral contraceptives that inhibit the body's fertility level through chemical means. The oral contraceptive contains synthetic hormones that alter the woman's hormonal system so that ovulation is prevented. The birth control pill has been around since the 1960s and is popularly used even today. The modern combination pills are popular on account of the fewer side effects and high success rate. But the birth control pill does not offer any protection against sexually transmitted diseases (STDs) or HIV and AIDS.

Estrogen and progesterone are the key hormones that keep a woman's menstrual cycle going. The contraceptive pill contains both these hormones, which go into making a hostile environment for an embryo to develop. Modern pills contain less estrogen than their earlier versions. The birth control pill works as a contraceptive by blocking the release of an egg. While a woman is on birth control pill, the brain no longer signals the ovaries to produce an egg each month. In this way, the contraceptive pill seeks to block ovulation so as to prevent a pregnancy. The cervical mucous becomes thick and unreceptive to sperm thereby making its progress through the fallopian tubes difficult. The endometrium also becomes unreceptive to receive the fertilized egg.

The combined birth control pills contain both the hormones estrogen and progesterone. Combination pills prevent the ovaries from releasing eggs. The progesterone-only contraception pills thicken the cervical mucus making it difficult for the sperm to travel. Combination pills are more effective than progesterone only pills. The success rate of birth control pills is about 97 - 99%, if taken correctly. The pill is an easily reversible method of contraception. If the woman is also taking antibiotics such as rifampin or anti-seizure medications, the birth control pill may not be as effective. Some anti-HIV protease inhibitors and anti-fungal oral medication may also affect the efficacy of oral contraceptives.
