The second half of the menstrual cycle is known as the luteal phase, which follows ovulation. It is named after the corpus luteum, which is the structure that forms in the ovary after the release of the egg. During the luteal phase, the corpus luteum produces the hormone progesterone, which helps prepare the uterine lining for possible pregnancy. If fertilization and implantation occur, the progesterone helps maintain the pregnancy until the placenta takes over hormone production.
The length of the luteal phase can vary from person to person but is typically around 12 to 14 days. If pregnancy does not occur, the corpus luteum will begin to break down, causing a decrease in progesterone and triggering the start of menstruation.
Tracking the length of the luteal phase can be helpful for those trying to conceive, as a shorter than usual luteal phase may indicate a potential fertility issue. Aashakiran IVF may recommend interventions such as progesterone supplementation or further testing to help improve chances of pregnancy.
