This increase is called the luteinizing hormone surge, which can then be detected in a woman's urine 8 to 12 hours later. Because luteinizing hormone promotes the maturation of an egg in the ovary, the amount of LH usually increases 20 to 48 hours before ovulation. This special kit measures the amount of luteinizing hormone (LH) in the urine. If the woman does not wish to become pregnant, she should not have sexual intercourse at all for 3 to 4 days after she notices the change in her cervical mucus.Ī woman can use an ovulation prediction kit to determine when she is most likely to ovulate. During this period, it is recommended that she have sexual intercourse only every other day because the presence of seminal fluid makes it more difficult to determine the nature of her cervical mucus. She may choose to have intercourse between the time of her last menstrual period and the time of change in the cervical mucus. A woman can learn to recognize differences in the quantity and quality of her cervical mucus by examining its appearance on her underwear, pads, and toilet tissue or she may gently remove a sample of mucus from the vaginal opening using two fingers. This so-called egg-white cervical mucus (EWCM) stretches for up to an inch when pulled apart. A woman will generate larger amounts of more watery mucus than usual (like raw egg white) just before release of an egg from her ovary.

The mucus inspection method depends on the presence or absence of a particular type of cervical mucus that a woman produces in response to estrogen. QUESTION Which of the following are methods for contraception? See Answer To use the basal body temperature as a birth control method, a woman should refrain from having sexual intercourse from the time her temperature drops until at least 48 to 72 hours after her temperature increases again. Online calculators are available to help a woman chart her basal body temperature. A special thermometer that is more accurate and sensitive than a typical oral thermometer must be used, and the daily temperature variations carefully noted. The basal body temperature method requires that a woman take her temperature every morning before she gets out of bed. It is less than 1 degree F (about a half-degree C) when the body is at rest. Unfortunately, this temperature difference is not very large. The basal body temperature (BBT) method is based upon the fact that a woman's temperature drops 12 to 24 hours before an egg is released from her ovary and then increases again once the egg has been released. Although these methods were developed to prevent pregnancy, they can equally be well used by a couple to increase fertility and promote conception. But because the egg survives 3 to 4 days (6 to 24 hours after ovulation) and the sperm can live 48 to 72 hours (up to even 5 days in fertile mucus), the actual time during which a woman may become pregnant is measured not in hours, not in days, but in weeks.įAMS can be up to 98% effective, but they require a continuous and conscious commitment with considerable monitoring and self-control. On average, the egg is released about 14 (plus or minus 2) days before a woman's next menstrual period. In order to use a FAM, it is necessary to watch for the signs and symptoms that indicate ovulation has occurred or is about to occur. The fertility awareness methods (FAMs) are based upon knowing when a woman ovulates each month. Instead, these methods to prevent pregnancy require that a man and woman not have sexual intercourse during the time when an egg is available to be fertilized by a sperm.

Natural methods of contraception are considered "natural" because they are not mechanical and are not a result of hormone manipulation. Natural family planning, or fertility awareness, involves timing your sexual activity to avoid a woman's most fertile time. Disadvantages of natural methods are the fact that they can be difficult to use correctly and that sexual intercourse must be avoided at certain times of the month.avoidance of medications or procedures.lack of prescriptions or health-care visits, and.Examples of natural methods of birth control include the calendar rhythm method, basal body temperature method, and cervical mucus examination.
