Simples métodos de control de la natalidad: The Ape at the Brink of the Human Mind

This book gives specific instruction on the use of two methods of family planning: Natural Family Planning and Fertility Awareness Method.

These methods give couples natural choices:
1. To avoid pregnancy, you can determine when you are infertile and have sexual intercourse without conceiving.
2. To become pregnant, you can track the days of the month when you are most fertile and have intercourse when you are most likely to conceive.
3. These safe non-invasive techniques can be used by themselves or combined with other contraception methods.
4. The techniques are noninvasive, have no side effects and carry no danger of toxic infection or cancer.

The new material includes several new examples of natural birth control and the fertility awareness method, with illustrations. The book contains 40 charts for readers to use. The book is written in an accessible style and contains edifying case studies.
