What is a Luteal Phase?
The luteal phase is the phase of a woman’s cycle where the ripe egg is released. If it is fertilized, it will then implant itself in the lining of the uterus. This phase is generally consistent in length, lasting anywhere from 10-16 days. The first phase (the follicular phase) can fluctuate a little more. After ovulation occurs, the corpus luteum (or the ovarian follicle following ovulation) begins producing the hormone progesterone. Progesterone is important in many reproductive functions. First of all, it builds the uterine lining for implantation of a fertilized egg. It also increases the basal body temperature, and therefore incubates the fertilized egg after conception. If pregnancy occurs, progesterone prevents menstruation. If you get pregnant, your progesterone levels will remain elevated to sustain the pregnancy. How long Does The Luteal Phase Last? Generally, this second phase lasts about 14 days (for those with a regular 28-day cycle). However, it can vary anywhere from 10-1
