Recruiting studies
- NCT07499817RecruitingPhase 3
Effect of pentoxifylline on womb lining and frozen embryo transfer
This trial tests if a medication called pentoxifylline can help thicken the womb lining and improve success rates for frozen embryo transfers. It may be an option for people with a thin womb lining before their procedure.
Banī Suwayf, Beni Suweif GovernorateAges 18–43 - NCT07500337Recruiting
Improving embryos with fragmentation for IVF success
This trial tests a special technique to remove fragments from day-4 embryos before they grow into blastocysts. It may help people having IVF get better embryos and improve pregnancy chances.
Bisceglie, BTAges 20–42 - NCT05969795RecruitingPhase 1
Natural embryo transfer with or without progesterone support
This Phase 1 study compares pregnancy outcomes, especially live birth, when using a natural-cycle frozen embryo transfer with an embryo that is genetically euploid (normal chromosome number) versus doing transfers without luteal (progesterone) phase support. It may help determine whether adding progesterone around ovulation improves the chance of a live birth.
Abu DhabiAges 18–40 - NCT07480668Recruiting
Aromatherapy for emotional wellness during IVF
This study tests whether inhaling lavender essential oil can help reduce anxiety, stress, and depression for women waiting for IVF. You may benefit if you are feeling some emotional distress and are not using other mind-body or herbal treatments.
Belo Horizonte, Minas GeraisAges 18 years+ - NCT07461909Recruiting
Comparing Two Types of Vaginal Progesterone for Frozen Embryo Transfer
This study compares two forms of vaginal progesterone used to prepare the uterus for a frozen embryo transfer (FET). It may be a good option if you are already prescribed one of these progesterone regimens and are planning a single embryo transfer.
LisbonAges 18–48 - NCT07462065RecruitingPhase 4
Clomiphene with or without Pioglitazone for PCOS
This study compares two fertility treatments: clomiphene alone or clomiphene plus pioglitazone. It aims to see if adding pioglitazone improves ovarian stimulation in women with PCOS.
Islamabad, FederalAges 18–38 - 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.
Novi SadAges 18–40 - NCT06599528RecruitingPhase 1
Comparing a new hormone injection to Ovidrel in healthy women
This study compares a new injected hormone (SJ04) with a standard one (Ovidrel) to see if they work similarly. It's for healthy women with regular cycles who might need help with fertility treatments.
Suzhou, JiangsuAges 20–40 - NCT07409493Recruiting
Comparing two IVF methods with time-lapse imaging
This study compares two types of ovarian stimulation protocols (PPOS and GnRH antagonist) for women undergoing IVF with a freeze-all embryo plan. It uses time-lapse imaging to see if one approach leads to better embryo development.
HanoiAges 20–45 - NCT07409792Enrolling by invitation
Ear seed therapy for anxiety, sleep, and IVF success
This trial tests if sticking tiny seeds on ear points (auricular therapy) can help women going through IVF feel less anxious, sleep better, and possibly improve their chances of pregnancy. It is for women with infertility who are about to have a frozen embryo transfer and have some anxiety or sleep problems.
Hangzhou, ZhejiangAges 20–45 - NCT07394530Recruiting
Comparing two IVF stimulation methods for women with PCOS
This trial compares two types of ovarian stimulation protocols (PPOS and antagonist) for women with PCOS undergoing IVF to see which leads to better outcomes. If you have PCOS and are planning IVF, this study may help find the best approach for you.
Hanoi, HanoiAges 18–40 - NCT06045351RecruitingPhase 1
Vitamin D shots for women with PCOS and low vitamin D
This trial tests whether vitamin D injections can help females with polycystic ovary syndrome (PCOS) who also have low vitamin D levels. Participants will receive the injection and be monitored for changes in their condition.
Karachi, SindhAges 18–45 - NCT04390308Recruiting
Testing gentle stimulation of ovaries before fertility treatment
This trial studies whether a “mechanical stimulation” procedure can help small egg-making structures in the ovary start to work again in people with primary ovarian insufficiency. If the procedure shows signs of response, you may then move on to further fertility treatment, including IVF.
Abu Dhabi, Abu Dhabi EmirateAges 18–40 - NCT07384676Recruiting
Study on environment and lifestyle in infertility treatment
This study looks at how environmental and lifestyle factors affect infertility and the results of assisted reproductive technology (ART), such as IVF. It aims to help understand what might improve your chances of having a baby.
Changsha, HunanAges 18–46 - NCT06261671Recruiting
Antioxidants in embryo culture for healthier embryos
This study tests whether adding antioxidants to the liquid that embryos grow in can improve the chance of having healthy embryos with the right number of chromosomes. It is for people undergoing IVF with ICSI and embryo testing (PGT-A).
Abu Dhabi, Abu Dhabi EmirateAges 18–43 - NCT07371312Recruiting
Couples' outcomes after unsuccessful PGD cycles
This study looks at couples who tried for a baby using PGD (a way to check embryos for genetic diseases before pregnancy) but did not have a baby as a result. It wants to understand what happened next for these couples and how they felt about the process.
ClamartAges 18 years+ - NCT07375238Recruiting
Gazpacho daily for better sperm health
This study tests whether drinking gazpacho daily can improve sperm quality and reduce stress in the body. It may help men with low or abnormal sperm counts.
Madrid, MadridAges 18–45 - NCT06841861RecruitingPhase 1/Phase 2
Testicular organoid study for male fertility
This trial uses tiny lab-grown testicles to study sperm production. It may help men with infertility learn more about why they can't make sperm.
San Francisco, CaliforniaAges 18–60 - NCT07358468Recruiting
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 - NCT07359703Recruiting
Aurora test for better embryo selection in ICSI
This study tests a new tool called the Aurora test, which looks at your eggs to help choose the best embryo for transfer. It may help improve success in your first few ICSI cycles.
GhentAges 18–40 - NCT00353197Recruiting
Donating long-stored IVF embryos for stem cell research
This study creates new lab cell lines from donated human embryos to support future clinical research. It may help researchers develop better treatments by starting from donated embryos that are carefully screened and consented.
JerusalemAges 18 years+ - NCT00353210Recruiting
Use embryos from IVF for stem cell research
This study creates human stem cell lines from embryos left over after IVF. It may help researchers learn about stem cells, but you must agree to give consent and not use these specific embryos for building your family.

Comparing two fertility drugs in Japanese women with hormone deficiency
This study tests if a combination of two hormone drugs (follitropin alfa/lutropin alfa) works as well as another drug (hMG) for Japanese women with low LH and FSH levels who are doing in vitro fertilization (IVF). The goal is to help them produce eggs for pregnancy.
