基础体温常用来决定有无排卵和排卵时间的方法之一。过去研究指出:当血液中黄体酮浓度达到4毫微克/毫升时,由于黄体酮的致热作用,可使基础体温明显上升,而且基础体温上升时间常与排卵时间相一致。但临床经验表明,单相型基础体温并非一定无排卵。本研究主要阐明单相型基础体温和排卵与否的关系。 Basal body temperature is often used to determine whether ovulation and ovulation time method. Past studies have shown that when the concentration of progesterone in the blood reaches 4 ng / ml, the basal body temperature can be significantly increased due to the pyrogenic pyrogenic effect, and the basal body temperature rise time is always consistent with the ovulation time. However, clinical experience shows that single-phase basal body temperature is not necessarily no ovulation. This study mainly clarifies the relationship between single-phase basal body temperature and ovulation or not.
