- NCT07136922RecruitingPhase 1
Testing a new progesterone tablet for luteal phase issues

CoventryAges 18–45 - NCT07372495Recruiting
Cerclage with progesterone vs progesterone alone for twin pregnancy with short cervix

Low dose progesterone injection for ovulation
This trial tests whether a low dose of progesterone (a hormone) can help trigger ovulation in women who have trouble getting pregnant. It may offer a new option for women with infertility.

Waterloo, OntarioAges 18–30 - NCT06834594RecruitingPhase 4
Bleeding patterns in teens with Turner syndrome on progesterone
This study looks at how different ways of taking progesterone (a hormone given along with estrogen) affect bleeding patterns in teens with Turner syndrome. The goal is to find the best hormone schedule to cause regular, predictable periods.
Kansas City, MissouriAges 12–20 - 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+ - 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 - 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 - 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 - NCT06856174RecruitingPhase 4
Menopause Hormone Therapy for Women with HIV
This trial tests whether hormone therapy can help manage hot flashes and night sweats in women living with HIV who are going through menopause. It's designed to see if this treatment is safe and effective for this group.
Birmingham, AlabamaAges 40–60 - 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 - NCT06807580RecruitingPhase 2
Adding progesterone to gender-affirming hormone therapy: a study for transgender women
This study tests whether adding progesterone to your current hormone therapy helps transgender women feel better and more satisfied with their treatment. It might be a good fit if you've been on hormones for at least 6 months and haven't used progesterone before.
Atlanta, GeorgiaAges 18–60 - 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.
GuangzhouAges 20–40 - NCT05586724RecruitingPhase 3
Progesterone vs another hormone added to estrogen for menopause symptoms
This Phase 3 study compares two types of progesterone—micronized progesterone versus norethisterone acetate—both used with estrogen to treat menopause symptoms that affect daily life. It aims to see which combination works better and is tolerated over time for women with an intact uterus.
StockholmAges 45–60 - NCT04783857RecruitingPhase 4
Hormone therapy to prevent smoking relapse after childbirth
This trial tests whether giving progesterone after childbirth can help new mothers stay quit from smoking, reducing secondhand smoke exposure to their babies. It's for women who smoked before pregnancy and want to remain smoke-free after delivery.
Minneapolis, MinnesotaAges 18–45 - NCT00929006RecruitingEarly Phase 1
Testing progesterone effects on hormone timing during sleep in teens
This early-phase study tests whether a progesterone medicine can change when “luteinizing hormone” (a puberty-related hormone) pulses during wake versus sleep. It focuses on pubertal girls with either normal or higher-than-expected testosterone levels to see how their hormone timing responds.
Charlottesville, VirginiaAges 10–17 - NCT07448597RecruitingPhase 4
Progesterone for preventing preeclampsia
This trial tests if taking progesterone early in pregnancy can help prevent preeclampsia, a condition of high blood pressure. You may qualify if you are over 18, speak English, and are less than 12 weeks pregnant.
Charleston, South CarolinaAges 18 years+ - NCT07508657RecruitingPhase 4

Hong KongAges 18–42 - NCT07340827RecruitingPhase 3
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.

Estradiol to improve brain and reward changes in midlife women
This study tests whether a hormone called estradiol (given as a patch and pill) changes how the brain and body respond to reward in some midlife women with low pleasure and/or psychosis symptoms during menopause transition. It may help researchers understand whether estrogen treatment can improve mood-related “reward” function in this group.

Common questions
- Are there clinical trials studying Progesterone?
- Yes. Clin2 currently lists 54 recruiting studies that include 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 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 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 Progesterone or a specific trial is right for you.
