HEALTH & MEDICINE CALCULATOR
Luteal Phase Calculator
A precise tool.
What is the Luteal Phase Calculator & How does it work?
The luteal phase is the period in a woman’s menstrual cycle that occurs after ovulation and before menstruation begins. It typically lasts about 12 to 16 days, during which the corpus luteum produces progesterone, which helps prepare the uterine lining for pregnancy.
If a fertilized egg implants in the uterus, the corpus luteum continues to produce progesterone and estrogen, supporting early pregnancy. If no implantation occurs, the corpus luteum degenerates, leading to the shedding of the uterine lining and menstruation.
