Recruiting studies
- 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 - NCT05899010RecruitingPhase 3
Micronized progesterone for frozen embryo transfers
This Phase 3 study tests whether adding micronized progesterone during frozen embryo transfer cycles helps support embryo implantation and pregnancy. You may benefit if your care team is already preparing the uterus with hormone therapy for a blastocyst transfer.
BarcelonaAges 18–50 - 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 - NCT06463652Recruiting
Cervical stitch with progesterone for short cervix
This trial tests whether adding a cervical stitch (cerclage) to progesterone treatment helps prevent early birth better than progesterone alone in women with a short cervix.
Ho Chi Minh City, Ho Chi Minh CityAges 18 years+ - NCT05080569RecruitingPhase 4
Extra support after IUI for couples with unclear infertility
This study tests whether adding support in the period after ovulation (the “luteal phase”) helps people who are starting IUI (intrauterine insemination) because their infertility is unexplained. It’s designed to see if the added care improves chances when mild ovarian stimulation is used.
UtrechtAges 18 years+ - NCT06150703RecruitingPhase 3
Luteal phase support with GnRH agonist after egg retrieval trigger
This trial tests whether giving a medication called a GnRH agonist during the luteal phase (the time after egg retrieval) can help with IVF success. It is for people who are using a specific medication protocol (recombinant FSH with an antagonist) and have certain hormone levels.
BondyAges 18–39 - NCT07305519Recruiting
Can supplements prevent early birth for short cervix?
This study tests if taking a combination of magnesium, a natural supplement (palmitoylethanolamide), hyaluronic acid, and vitamins B6 and D can help prevent preterm birth in women with a shorter-than-ideal cervix.
Rome, RMAges 18 years+ - NCT06036446Recruiting
Late cerclage for preventing early birth in high-risk pregnancies
This trial tests if placing a stitch in the cervix (cerclage) between 24 and 27 weeks of pregnancy can help prevent preterm birth in women whose cervix is short. It may be an option for those who find out late in pregnancy that they are at risk.
Charlotte, North CarolinaAges 18–50 - 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 - NCT05787509RecruitingPhase 4
Progesterone to help prevent early delivery after IVF
This trial tests whether taking progesterone for longer during an IVF pregnancy can help lower the risk of preterm birth (birth too early). It is for people who are pregnant from a fresh embryo transfer of a single embryo.

Common questions
- Are there clinical trials studying Vaginal Progesterone?
- Yes. Clin2 currently lists 10 recruiting studies that include Vaginal Progesterone, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Vaginal Progesterone trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Vaginal Progesterone an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Vaginal Progesterone or a specific trial is right for you.
