基礎體溫法
為了至少得到那麼一點安全期避孕的確定性，可以運用兩種不同的策略（實行安全期避孕的許多婦女實際上同時運用這兩種策略）：第一，在每天早晨起床前用特殊的體溫計（一般為口含式體溫計——譯者注）量本人的體溫，所得到的體溫叫基礎體溫（basal temperature）。在每次排卵前，基礎體溫有輕度的下降，在隨後的月經週期的其餘日期，基礎體溫則輕度上升。在決定採用安全期避孕時，通過比較至少6個月前的基礎體溫記錄，可以計算下一次月經週期的排卵時間。第二個推算“不安全的”日期的做法在於保存至少8個月的月經週期記錄。 |

Basal Temperature
In order to gain at least some certainty, a woman can use two different strategies (and many women who practice the "rhythm method" actually use both at the same time): First, she can take her body temperature with a special thermometer every morning before getting out of bed. This is called the
basal temperature. Before each ovulation, there is a slight drop in body temperature followed by a slight rise for the rest of the menstrual cycle. By comparing her temperature-records of at least six previous months, the woman can calculate the time of her next ovulation. A second way of finding the "unsafe" days consists in keeping a calendar record of menstrual cycles for at least eight months. |
