Senescent Endometrial Cells in Patients with Thin Endometrial Lining

Recruiting

• Conditions: Cell Senescence; Asherman's Syndrome; Thin Endometrial Lining

• Registration Number: NCT06450301
• Lead Sponsor: Trio Fertility

Brief Summary

The goal of this observational study is to determine if thin endometrial lining that is unresponsive to estrogen might be associated with the presence of senescent cells in patients following long-term use of oral contraceptives. The main question it aims to answer is:

Are there any senescent cells present in thin endometrial lining?

During the luteal phase of the cycle, participants will will undergo:

* Gynecologic US to measure the endometrial lining thickness and pattern.

* Endometrial biopsy with Pipelle catheter

Detailed Description

The investigators hypothesized that senescent cells in the endometrium may be the cause of the failure of thin endometrium to respond to normal growth stimuli such as estrogen.

The outcome that research team anticipate to measure is the percentage of senescent cells in the endometrial biopsies of women with thin endometrium compared to the control group biopsies.
