title: [Natural contraception--a real option?].
abstract: In the article, a method developed by John Billings is introduced, based on the presumption that a woman will learn to know her fertile days and the day of ovulation by observing the consistency of the cervical mucus. The method has many uses. The woman gets to know her body and its functions. The woman can avoid becoming pregnant without long periods of continence and she can get pregnant when she wants it herself. The method can also provide help in various problems of childlessness.
