Assisted hatching for embryo transfer in older women
Part of Women’s health & pregnancy clinical trials.
This study tests whether a special technique called assisted hatching (gently opening the outer shell of an embryo) can improve pregnancy success after a frozen embryo transfer in women aged 35 and older.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 35 years old
- This is your first or second time having a frozen embryo transfer
- Your embryos are of good quality (Grade I, II, CP or higher for cleavage-stage; Grade 4BC/CB or higher for blastocysts)
- You have not used donor eggs or sperm, or planned genetic testing on embryos
- You do not have severe immune or chromosome problems, or certain uterine conditions

This study compares two ways to choose which single blastocyst (a 5-6 day old embryo) to transfer after IVF. It looks at a noninvasive test versus the usual method of selecting by appearance, and aims to improve the chances of a successful pregnancy.
This study compares two different timings for a lab procedure called assisted hatching (making a small opening in the embryo's outer shell) to see if one helps more embryos implant. You may be eligible if you're doing IVF with a frozen embryo transfer of a single screened embryo.
This study looks at whether “endometrial compaction” (a technique used during frozen embryo transfer) improves pregnancy and baby outcomes. It focuses on people having a frozen transfer using embryos that test normal on genetic screening.
This study tests whether different acupuncture techniques can improve the success rate of frozen embryo transfers in women who have had repeated implantation failure. If you are under 40 and have had at least 3 failed transfers with high-quality embryos, you may be eligible to participate.
This trial compares a new method to time a frozen embryo transfer (using a test called ERA) with the standard method. The goal is to find the best time to transfer a high-quality embryo in women who have had multiple failed IVF attempts (recurrent implantation failure).
This study tests whether giving hCG before transferring a thawed embryo can improve success. It is for women who have at least one frozen embryo of good quality and are planning a frozen embryo transfer.
