Luteal Phase Defect: What Is It, Symptoms, Treatment

A luteal phase defect (LPD) leads to decreased progesterone levels and can cause shorter menstrual cycles, spotting and possibly infertility.
Many people only think about their menstrual cycle when they have their period about once a month. Sure, we all know the body goes through a whole cycle of hormonal changes throughout the month, but many women probably don’t give the rest of the cycle much thought unless there are issues.
