Ovarian Stromal Stiffness and Ovarian Reserve Parameters Via Transvaginal Shear Wave Elastography
August 18, 2026 updated by: Ihsan Bağlı, Saglik Bilimleri Universitesi Gazi Yasargil Training and Research Hospital
Relationship Between Ovarian Stromal Stiffness Measured by Transvaginal Shear Wave Elastography and Hormonal and Ultrasonographic Ovarian Function Parameters
This study aims to evaluate the relationship between ovarian stromal stiffness measured by transvaginal shear wave elastography (SWE) and conventional hormonal and ultrasonographic parameters of ovarian reserve.
Reproductive-aged female patients will be evaluated to determine whether tissue elasticity provided by SWE correlates with ovarian function markers such as anti-Müllerian hormone (AMH), antral follicle count (AFC), and ovarian volume.
Study Overview
Status
Not yet recruiting
Intervention / Treatment
Detailed Description
Transvaginal ultrasound combined with shear wave elastography will be performed on all participants.
Ovarian stromal stiffness values (measured in kilopascals or meters per second) will be correlated with basal serum hormone levels (AMH, FSH, LH, Estradiol) and ultrasonographic ovarian reserve criteria (antral follicle count and total ovarian volume).
