luteal phase defect
A condition where the luteal phase is too short or progesterone production is insufficient to support implantation.
Full Definition
Luteal phase defect (LPD) is a reproductive disorder characterized by inadequate progesterone production or a shortened luteal phase (less than 10 days). This condition can prevent successful implantation of an embryo or lead to early pregnancy loss. The luteal phase normally begins after ovulation when the corpus luteum produces progesterone to prepare and maintain the endometrium for pregnancy. Diagnosis may involve measuring progesterone levels or endometrial biopsy, and treatment typically includes progesterone supplementation.
