The woman or couple learns to identify days surrounding ovulation when conception is possible. Natural changes that occur in the cervix, cervical mucus, and basal body temperature identify the fertile and infertile phases in each menstrual cycle. A man is considered fertile all of the time, while a woman is fertile only a few days each menstrual cycle. This information enables couples to make responsible and knowledgeable decisions depending on their desire to achieve or avoid pregnancy. In order to achieve this high degree of effectiveness, a woman or couple must be motivated, willing to abstain during certain times in the cycle, and have a thorough understanding through instruction given by trained, certified instructors.
