luteal phase deficiency
Inadequate progesterone production during the luteal phase affecting endometrial development and implantation.
Full Definition
Luteal phase deficiency (LPD) refers to insufficient progesterone secretion or action during the post-ovulatory phase of the menstrual cycle. This condition results in inadequate endometrial preparation for embryo implantation and may lead to recurrent pregnancy loss or infertility. In reproductive endocrinology practice, LPD diagnosis relies on endometrial biopsy timing, serum progesterone measurements, and luteal phase length assessment. Treatment typically involves progesterone supplementation during the luteal phase or early pregnancy to support endometrial receptivity and maintain pregnancy viability.
