This study tests a new device for transferring embryos during IVF (in vitro fertilization). It is for women who have at least one genetically normal frozen embryo and a low risk of transfer complications.
Barcelona, BarcelonaAges 18–50 - NCT06307184Recruiting
Natural cycle frozen embryo transfer convenience study
This study is testing whether starting a frozen embryo transfer during your natural cycle (after ovulation) is more convenient than the usual schedule. You will take progesterone (400 mg twice a day) and have one embryo transferred. It is for people using donor eggs who have regular cycles.

LisbonAges 18–48 - NCT07171970Recruiting
IVM vs IVF for women with PCOS
This trial compares two fertility treatments for women with PCOS: in vitro maturation (IVM) with fresh embryo transfer versus standard IVF with frozen embryo transfer. It aims to find which approach leads to better outcomes.
Ho Chi Minh CityAges 18–42 - NCT06526520Recruiting
Relaxin levels in frozen embryo transfer preparation
This study looks at a hormone called relaxin during different ways of preparing the uterus for a frozen embryo transfer. It may help understand which preparation method works best for women who are not trying to get pregnant right now.
Abu Dhabi, Abu Dhabi EmirateAges 18–35 - NCT06896617RecruitingPhase 4
Corpus Luteum's effect on frozen embryo transfer pregnancies
This study looks at whether having a corpus luteum (the structure left after an egg is released) affects pregnancy outcomes in frozen embryo transfer cycles. It aims to help doctors choose the best way to prepare the body for embryo transfer.
Barcelona, SpainAges 18–41 - NCT06746129RecruitingPhase 3
Comparing Day 3 vs Day 5 Embryo Transfer for IVF With Few Embryos
This trial compares transferring embryos at the cleavage stage (day 3) versus the blastocyst stage (day 5) for women who have few embryos during an IVF cycle. It may help determine which stage gives the best chance of pregnancy for people with limited embryos.
Boston, MassachusettsAges 18–44 - NCT04472156Recruiting
Testing one embryo transfer after mosaic PGT results
This study follows people who have infertility and, after IVF testing (PGT), have a “mosaic” embryo result. It looks at transferring one embryo to see how this approach works when mosaic changes are present.
Lone Tree, ColoradoAges 18–45 - NCT06471140Enrolling by invitation
Heart Health in Pregnancy After Frozen Embryo Transfer
This study looks at how the heart and blood vessels adjust during pregnancy in women who became pregnant after a frozen embryo transfer (FET) using IVF. It aims to understand if different types of FET cycles affect maternal health, and may help improve future fertility care.
AalborgAges 18–40 - NCT06875752RecruitingPhase 4
Does frozen embryo transfer need luteal support?
This trial checks if taking extra hormones after a frozen embryo transfer (called luteal support) is needed when using your natural cycle. It may help improve pregnancy chances.
Budapest, BudapestAges 18–40 - NCT06239376Recruiting
Hormone pretreatment before frozen embryo transfer for adenomyosis
This study tests whether using a hormone medication (GnRH agonist) before a frozen embryo transfer helps women with adenomyosis. If you have adenomyosis and are planning a frozen embryo transfer, this trial will help compare results with or without the pre-treatment.
Ho Chi Minh City, Ho Chi Minh CityAges 18–42 - NCT04109846Recruiting
Embryo transfer using aneuploid or mosaic embryos during pregnancy
This trial looks at pregnancy and baby outcomes when embryos that have chromosome differences (aneuploidy or mosaic embryos) are transferred, especially when no other embryos are available. It may help people understand the risks and expected outcomes in situations where options are limited.
Sunnyvale, CaliforniaAges 18–55 - NCT06064669Recruiting
Metformin for healthy live birth in women with prediabetes
This study tests if metformin, a drug that helps control blood sugar, can improve the chance of a healthy live birth in women with prediabetes who are doing in vitro fertilization (IVF). It aims to see if treating prediabetes before and during early pregnancy leads to better outcomes.
Jinan, ShandongAges 20–40 - NCT06644794RecruitingPhase 3
Progesterone timing for frozen embryo transfer
This trial compares two ways of timing progesterone support for frozen embryo transfer in women with regular cycles. It aims to find which approach gives the best chance of pregnancy.
Jinan, ShandongAges 21–44 - NCT07801105Recruiting
Hormone-free egg collection for storing embryos
This study tests a new way to collect eggs without using fertility hormones, then fertilize them and freeze the embryos for later transfer. It may help women who want to avoid hormone injections, but it requires several monitoring visits and specific health criteria.
Bedford, TexasAges 18–35 - NCT07425990Recruiting
Comparing natural cycle types for frozen embryo transfer
This study compares two types of natural cycle preparation for frozen embryo transfers to see which leads to more pregnancies. It may be a good fit if you are using your own eggs, have regular cycles, and are planning a frozen embryo transfer.

How womb lining movement affects frozen embryo transfer success
This study looks at how different ways of preparing the uterus for a frozen embryo transfer affect the natural wavelike movements of the womb lining (endometrial peristalsis). It may help doctors choose the best protocol for you.
Ho Chi Minh CityAges 18–42 - NCT07675213Recruiting
Uterine muscle movements and pregnancy after frozen embryo transfer

Ketorolac for fresh embryo transfer in IVF
This trial tests whether a medicine called ketorolac (a type of NSAID, similar to ibuprofen) can improve outcomes when you have a fresh embryo transfer during IVF. It may help reduce cramping or inflammation that could affect implantation.
