Luteal Phase Defect

Luteal phase defect is a condition where the uterine lining does not mature adequately after ovulation, often due to insufficient progesterone production from the corpus luteum. This can shorten the luteal phase and make it difficult for a fertilized egg to implant and grow, leading to infertility or early miscarriage.

Women may notice short menstrual cycles, spotting before periods, or recurrent pregnancy loss, and diagnosis can involve hormone tests and cycle tracking. Treatment focuses on correcting underlying causes such as thyroid or prolactin disorders, and may include progesterone supplementation, ovulation induction medicines, and lifestyle changes under specialist guidance.?
