Complex endometrial wave-patterns in IVF.

Area of Science:

• Reproductive Medicine
• Medical Imaging
• Gynecology

Background:

• Endometrial waves are crucial indicators of uterine receptivity during IVF cycles.
• Existing classification systems may not fully capture the complexity of endometrial wave patterns.

Purpose of the Study:

• To develop a refined endometrial wave classification system.
• To improve the description of complex endometrial wave patterns observed during IVF.

Main Methods:

• Descriptive study conducted at a university hospital-based fertility clinic.
• Ultrasound examinations performed on 24 patients undergoing IVF on the day of hCG administration.
• Analysis focused on endometrial wave types and interobserver/intraobserver agreement.

Main Results:

• Two novel wave types were identified: recoiling CF waves and standing waves.
• Alternating CF and FC wave patterns within the same endometrial fragment were described.
• Strong agreement was observed for interobserver and intraobserver reliability (kappa values).

Conclusions:

• The refined classification system enhances the ability to describe complex endometrial wave types in IVF.
• This improved system aids in the detailed assessment of the endometrium on the day of hCG administration.
