To evaluate the frequency, direction, and physiological characteristics of endometrial cavity movements and intracavitary fluids across spontaneous and stimulated menstrual cycles.
Assessed uterine endometrial movements via transvaginal ultrasound across 273 cycles, comprising 180 spontaneous cycles in 72 patients, 75 clomiphene citrate cycles in 18 patients, and 18 gonadotrophin cycles in 11 patients.
Tracked and recorded the presence and directional pattern of intracavitary motion during the mid-follicular, late follicular, and luteal phases.
Endometrial movements occurred in 74% of scans during the mid-follicular phase, 96% during the late follicular phase, and 72% during the luteal phase.
Movement of echo-free space within the endometrial cavity was restricted entirely to the late follicular phase when cervical mucus production peaked.
Intracavitary fluid exhibited multidirectional to-and-fro vertical (cervix to fundus) and horizontal fundal movements with fern-leaf crystallization patterns, indicating active communication between the cervical canal and Fallopian tubes.

Implication

Observational study reveals distinct endometrial cavity movements during the late follicular phase, suggesting active fluid circulation between the cervix and fallopian tubes.
