Luteal Phase
Definition
The luteal phase is the second half of the menstrual cycle, occurring after ovulation and lasting approximately 12–14 days. During this phase, the corpus luteum produces progesterone to prepare the uterine lining for potential implantation. If pregnancy doesn't occur, progesterone levels drop, triggering menstruation.
Why It Matters
A healthy luteal phase is essential for fertility and hormonal balance. Luteal phase defects—characterized by low progesterone or a phase shorter than 10 days—can cause PMS, irregular bleeding, early miscarriage, and infertility. Supporting progesterone production during this phase optimizes reproductive health.

Frequently Asked Questions
A luteal phase defect occurs when the luteal phase is too short (less than 10 days) or progesterone levels are inadequate to support the uterine lining. This can result in difficulty conceiving, early pregnancy loss, PMS, and irregular spotting before menstruation.
Natural support includes vitamin B6 and magnesium supplementation, seed cycling with sunflower and sesame seeds, using vitex (chasteberry) to boost progesterone, managing stress, ensuring adequate healthy fats, and optimizing thyroid function.
