How can you prevent a future unwanted pregnancy?

 

About 85% of sexually active women who do not use contraceptives become pregnant within a year. A woman can become pregnant while breastfeeding, from about 10 days after childbirth, and even during her menstruation. Withdrawal of the penis prior to ejaculation and periodic abstinence does not prevent pregnancy or spread of sexually transmitted diseases. Here you can read more about several forms of contraceptives.

You can prevent an unwanted pregnancy with:
1- Total Abstinence
2- Use of contraceptives

If you are sexually active and do not want to get pregnant, always use contraception.

Methods of Contraception:
No method of contraception gives 100% protection.
The male latex condom is the only contraceptive method considered highly effective in reducing the risk of sexually transmitted diseases (STD's). Birth control pills, Implant and IUDs do not protect against STD infection.

For the Woman

DIAPHRAGM is a rubber disk with a flexible rim that covers the cervix and must be used together with spermicide. It is available by prescription only and must be fitted for size by a health professional. The diaphragm protects for six hours and should be left in place for at least six hours after intercourse but not for longer than a total of 24 hours.

ORAL CONTRACEPTIVES protect against pregnancy by the combined actions of the hormones estrogens and progestin. The hormones prevent ovulation. The pills have to be taken every day as directed and do not work after vomiting or diarrhea. Side effects of the pill can be nausea, headache, breast tenderness, weight gain, irregular bleeding, and depression.

DEPO-PROVERA is a hormonal contraceptive injected into a muscle on the arm or buttock every three months. The injection must be repeated every 3 months. The menstruation can become irregular and sometimes even absent.

IMPLANTS (such as Norplant or implanon) are made up of small rubber rods, which are surgically implanted under the skin of the upper arm, where they release the contraceptive steroid levonorgestrel. Their protection lasts from 3 to 5 years. Side effects include menstrual cycle changes, weight gain, breast tenderness and loss of bone mass.

Cupper-IUD is a T-shaped device inserted into the uterus by a health-care professional. The IUD can remain in place for 5- 10 years. IUD’s have one of the lowest failure rates of contraceptive method. Sometimes the IUD can be expelled and a woman has to check each month after her period with her finger if she can still feel the threads of the IUD. Other side effects can include abnormal bleeding and cramps, but this usually only occurs during and immediately after insertion. 

Hormonal-IUD is an IUD with a small hormonal (progestogen) sleeve. It is one of the most effective forms of birth control. Next to the above mentioned characteristics of an IUD, it can remain in place for 5 years, but has no heavy bleeding side effects. As most women experience only lighter periods and less bleeding (some stop completely having periods) it’s supposed to be a perfect therapy as well for women with heavy cycle bleedings.

FEMALE STERILIZATION is done surgically. The tubes are ligated, preventing the egg-cells from encountering the sperm cells and preventing any future pregnancies. It is a permanent form of contraception. 

FEMALE COMDOM is made of soft rubber and can be used only once. As a mechanical barrier method of contraception worn by women it’s inserted easily inside the vagina before sex and prevents direct vaginal contact with semen, infectious genital discharges, and genital lesions  It is shaped like a long tube or sheath, with one closed end and one open end, and at each end, there's a flexible ring, helping to keep the female condom in place once it's inserted. Condoms are the most effective method for reducing the risk of infection from the viruses that cause AIDS and other sexually transmitted diseases (STD’s). 

EMERGENCY CONTRACEPTION must be taken within 72 hours of unprotected sex, however, the sooner used, the more effective. iI prevents an unplanned pregnancy among others by delay of ovulation.

Most combination (estrogens and progesterone) birth control pills can also be used (called Yupze method). Take within 72 hours of unprotected sex. One dose 100 µg ethinylestradiol + 500 µg levonorgestrel (2-4 birth control pills), 12 hours later a second dose.

MORNING-AFTER cupper IUD must be inserted within 5 days of unprotected intercourse. The IUD can stay for 5 to 10 years.

For the Man

CONDOMS are usually made from latex rubber and can be used only once. Some have spermicide added to kill sperm. They act as a mechanical barrier, preventing direct vaginal contact with semen, infectious genital discharges, and genital lesions. Condoms are the most effective method for reducing the risk of infection from the viruses that cause AIDS and other sexually transmitted diseases (STD’s). It is important to put a condom on properly before intercourse

MALE STERILIZATION also known as vasectomy, is a quick operation performed under local anaesthesia with possible minor postsurgical complications, such as bleeding or infection. The ability to get an erection and an ejaculation does not disappear. The sperm cells are just a very small part (1%) of the fluid and a man will not notice any difference in ejaculation. The body will absorb the sperm cells.
