Endometrial receptivity can be assessed using various techniques:
1. Ultrasound: Transvaginal ultrasound is frequently used to evaluate endometrial thickness, which is considered a marker of receptivity. An endometrial thickness of 7-14 mm is generally deemed favorable.
2. Histological Examination: A biopsy of the endometrium during the luteal phase can provide information about the tissue's structure and the presence of certain cellular markers.
3. Molecular Diagnostics: Tests like the Endometrial Receptivity Array (ERA) analyze the expression of specific genes associated with receptivity, providing a personalized assessment of the optimal implantation window.
