Levonorgestrel implantation is the first completely new method of protection proposed in the United States for many years. Better known by the brand name Norplant, a contraceptive consists of six small capsules containing progestin, the same synthetic hormone that is used to suppress ovulation in oral contraceptives. Implanted under the skin of the hand, these capsules gradually release progestin, providing a pregnancy warning for approximately five years. After removing the capsules, fertility is restored.
Before the Food and Drug Administration approved the use of the implant in 1990, the norplant was tested on more than 50,000 women around the world and was highly effective. Statistically, your chance of getting pregnant with a wired implant is about 1 percent, which makes it as effective as oral contraceptives.
The biggest drawback of the implant, apparently, is that it violates the regularity of menstruation. In most women, menstruation either stops or becomes profuse, or bloody discharge appears on the underwear. Some of these phenomena disappear after the first year; the method as a whole is very well received in one of the studies, 94 percent of women said that they would like to use this method in the future, despite the fact that 95 percent had side effects. In addition to irregular menstruation, side effects such as headaches, acne, hair loss, and weight gain have been reported. Another disadvantage was that the implant showed less effectiveness in women weighing more than 154 pounds at the time of implantation and for women who gained a lot of weight later. Efficiency decreases with weight gain. In addition, this contraceptive is very expensive, at least 500 dollars.
Although there is little data on the health effects of contraceptives containing only progestin, experts consider it unlikely that the risk of cardiovascular disease is increased, since the hormone estrogen affects the development of cardiovascular disease. As with oral contraceptives, you will be protected to some extent from inflammation of the pelvic area, benign tumors of the breast and ovarian cysts. The use of progestin is associated with an increase in blood pressure, which is a risk factor regarding the likelihood of a stroke.
CONTEMPOINT PILLS AND CANCER
Perhaps most of all, women are worried about whether there is a connection between oral contraceptives and breast cancer, which seems more and more confused with each new study. According to the results of one study, it turns out that yes, pills that prevent pregnancy, contribute to the development of breast cancer. The results of another equally thorough study suggest that, no, birth control pills do not cause cancer.
What is the matter? In Atlanta's Centers for Disease Control, an experiment was conducted on 10,000 women to explain these seemingly contradictory results. The confusion is due to the fact that the use of oral contraceptives seems to increase the risk of developing breast cancer in women under the age of 35, but reduces the risk for women after forty-five years.
“One theory that can explain such a strange connection between birth control pills and cancer in young women suggests that the hormones in the pills themselves do not cause cancer, but they accelerate the development of cancer that would otherwise be diagnosed later,” says D Dr Forrest. According to another theory, women taking pills are more likely to be screened, so cancer is detected at an earlier stage. There is another theory according to which pills, like pregnancy, increase the risk of breast cancer on a short-term basis, but reduce it in the long term.
