Patient's question:
NoDoctor's answer:
Luteal phase defect refers to insufficient progesterone secretion by the pituitary gland or premature luteal regression, leading to poor secretion of the endometrium and consequently difficulty in implantation of the fertilized egg or early pregnancy miscarriage. The exact cause is still unclear. It may be related to insufficient luteinizing hormone (LH) or follicle-stimulating hormone (FSH) secretion by the pituitary gland, excessive or insufficient prolactin secretion by the pituitary gland; in some cases, it is due to the immaturity of the follicle itself and its insensitivity to gonadotropins; in other cases, it may be related to insufficient progesterone synthesis capacity of the corpus luteum or an imbalance in the ratio of estrogen and progesterone. Luteal phase defect can lead to menstrual disorders, infertility, habitual abortion, and some gynecological diseases. It is recommended to seek medical attention as soon as possible and receive standardized treatment under the guidance of a doctor.
