What this trial studies

This randomized trial investigates the effect of growth hormone (GH) supplementation on the euploid rate of blastocysts in women aged 38 and older undergoing preimplantation genetic testing for aneuploidy (PGT-A). Participants will be randomly assigned to receive either GH during ovarian stimulation or standard treatment without GH. The primary outcome measured will be the rate of euploid blastocysts, which are embryos with the correct number of chromosomes. This study aims to determine if GH can improve embryo quality in older women facing infertility.

Who should consider this trial

Good fit: Ideal candidates are women aged 38 and older who are planning to undergo PGT-A and meet specific health criteria.

Not a fit: Patients with significant uterine abnormalities or those with a history of certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the chances of achieving healthy pregnancies for older women undergoing IVF.

How similar studies have performed: While the use of growth hormone in IVF is being explored, this specific approach in older women undergoing PGT-A is relatively novel and has not been extensively tested.
