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.

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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Study Population

Female Patients of Reproductive Age (18-45 years) presenting to the gynecology outpatient clinic for routine gynecological evaluation or ovarian function assessment

Description

Inclusion Criteria:

  • Female patients aged 18 to 45 years.
  • Regular menstrual cycles (21-35 days) or irregular menstruel cycles (oligo-anovaltion)
  • Normal pelvic anatomy on baseline ultrasound evaluation.
  • Written informed consent to participate in the study.

Exclusion Criteria:

  • Use of hormonal contraceptives, ovulation induction agents, or hormone therapy within the last 3 months.
  • Pregnancy or current lactation.
  • Severe obesity or technical limitations preventing adequate transvaginal ultrasound and elastography imaging
