Luteal phase defect. Etiology, diagnosis, and management

Area of Science:

• Reproductive Endocrinology
• Gynecology

Background:

• Luteal phase defect (LPD) is a significant ovulatory disorder linked to infertility and recurrent spontaneous abortion.
• It represents a subtle disruption in ovulation or luteal function, potentially the most common ovulatory issue in women.
• Pathophysiology involves disordered folliculogenesis, corpus luteum dysfunction, and inadequate early pregnancy luteal rescue, leading to delayed endometrial maturation.

Purpose of the Study:

• To review the clinical significance, diagnosis, and management of Luteal Phase Defect (LPD).
• To discuss various clinical conditions that can manifest as LPD.
• To evaluate current and future diagnostic methods and treatment strategies for LPD.

Main Methods:

• Review of existing literature on Luteal Phase Defect.
• Discussion of diagnostic tools including endometrial biopsy, hormone assays, and ultrasonography.
• Analysis of treatment options such as progesterone replacement and clomiphene citrate.

Main Results:

• Endometrial biopsy is a recognized diagnostic tool for LPD, though standardization is pending.
• Clinical conditions like hyperprolactinemia and hyperandrogenism can present as LPD.
• Progesterone replacement and clomiphene citrate are effective treatments, with no significant difference in efficacy noted.
• Successful correction of LPD via endometrial biopsy leads to favorable conception and live birth rates.

Conclusions:

• Luteal phase defect is a clinically important condition impacting reproductive outcomes.
• Accurate diagnosis may be enhanced by future tests, but current methods like endometrial biopsy are valuable.
• Effective treatments exist for LPD, significantly improving pregnancy success rates.
