This study is looking at the best time to perform Laser Assisted Hatching, a procedure used in in vitro fertilization (IVF) to help an embryo implant. Researchers are comparing performing this procedure on Day 3 (cleavage stage) versus Day 5, 6, or 7 (blastocyst stage) of embryo development. The goal is to see if timing affects the "blastulation rate" (how often embryos develop into blastocysts), measured one week after egg retrieval. You may be able to join if you are a woman between 18 and 42 years old, undergoing IVF with a plan for a frozen embryo transfer, and meet specific criteria for ovarian health and BMI. The study's current status is unclear.

Study design

This is an interventional study planning to enroll 75 participants. Each participant's fertilized eggs will be split into two groups, with one group receiving Day 3 assisted hatching and the other receiving Day 5, 6, or 7 assisted hatching.

What's involved

Not specified in the trial record.

Compensation

Not stated in the trial record.

Follow-up

The primary outcome, blastulation rate, is measured one week after vaginal oocyte retrieval (VOR).
