Natural family planning

Natural family planning (NFP) is a method of birth control that does not require the use of physical devices or drugs. It involves the identification of the fertility period in the menstrual cycle, to either avoid or achieve pregnancy.

Methods

There are several methods of natural family planning. These include:

• Symptothermal method: This method combines several natural family planning methods into one. It involves monitoring a combination of indicators such as basal body temperature, cervical mucus, and hormonal changes.

• Cervical mucus method: Also known as the Ovulation Method, this involves tracking changes in cervical mucus throughout the menstrual cycle to predict ovulation.

• Basal body temperature method: This method involves tracking the slight rise in basal body temperature that occurs directly after ovulation.

• Calendar-based methods: These methods involve tracking the length of the menstrual cycle in order to predict ovulation.

Effectiveness

The effectiveness of natural family planning methods varies, depending on the method and the user's diligence in tracking fertility signs. According to the World Health Organization, when used correctly and consistently, natural family planning methods can be up to 99% effective.

Advantages and disadvantages

Advantages of natural family planning include: no side effects, cost-effectiveness, and fostering a greater understanding of one's body. Disadvantages include: the need for diligent tracking, potential for user error, and not providing protection against sexually transmitted infections.
