Billings Ovulation Method® in the Peri-Menopausal Years
Woman is unique amongst females of all species in that her reproductive capacity ends in middle life. There is a progressive decline of fertility until, at about the age of 45 to 50 years, when perhaps she has another 25 or 30 years of active life ahead of her, she become infertile. The years during which fertility decreases are known as the climacteric (change of life). The term “menopause” is more strictly applied to the cessation of the menstrual bleeds.
