Hippo-Related Competing Endogenous RNA (ceRNA) Network Dysregulation and In Vitro Fertilization (IVF) Outcomes in Women With Diminished Ovarian Reserve

Egypt70 participantsStarted 2026-08-01

Plain-language summary

Diminished Ovarian Reserve (DOR) is an important cause of female infertility and is associated with poor ovarian response and lower pregnancy rates during In Vitro Fertilization (IVF). The molecular mechanisms underlying impaired follicular development in DOR remain incompletely understood. Increasing evidence suggests that non-coding RNAs and components of the Hippo signaling pathway play important roles in granulosa cell proliferation, apoptosis, and follicular development. This prospective observational cohort study aims to investigate the expression of the long non-coding RNA (lncRNA) Nuclear Paraspeckle Assembly Transcript 1 (NEAT1), microRNA (miRNA)-181a-5p, Hippo pathway components including Yes-Associated Protein 1 (YAP1) and Connective Tissue Growth Factor (CTGF), and Insulin-Like Growth Factor 1 (IGF1) in follicular fluid-derived cells from women with DOR undergoing IVF compared with women with normal ovarian reserve. The study will also evaluate relationships among these molecular markers and IVF outcomes, including oocyte quality, number of retrieved oocytes, and embryo developmental potential.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Expression levels of Nuclear Paraspeckle Assembly Transcript 1 (NEAT1), microRNA-181a-5p (miR-181a-5p), Yes-Associated Protein 1 (YAP1), and Connective Tissue Growth Factor (CTGF).

Timeframe: At oocyte retrieval during the participant's IVF cycle (approximately 10-14 days after initiation of controlled ovarian stimulation).
