Recruiting studies
- NCT06934785Recruiting
Comparing two fertility drugs for ovulation induction
This trial tests if combining two fertility medications (letrozole and clomiphene citrate) works better than using letrozole alone to help women with ovulation problems release an egg. The goal is to find a more effective treatment for women trying to conceive.
Ho Chi Minh City, Ho Chi Minh CityAges 18–40 - NCT06433518Recruiting
Comparing trigger shot sizes for older women with low egg reserve
This trial compares two different trigger shot sizes for women 35 and older who have low egg reserve. The goal is to find which trigger dose leads to the best egg retrieval results.
Ankara, AnkaraAges 35–44 - 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 - NCT06928844Recruiting
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.
CairoAges 20–35 - NCT07706374RecruitingPhase 1
Does exemestane help women with PCOS ovulate?
This study tests if exemestane, a medication, can safely help women with PCOS start ovulating. It's for women who haven't tried ovulation medications before and are being treated at UNC Fertility.
Raleigh, North CarolinaAges 18–40 - NCT05258292Recruiting
Track blood sugar changes with your period in type 1 diabetes
This study monitors how your blood sugar (glucose) changes across your menstrual cycle using a continuous glucose monitor. It may help researchers understand patterns that could improve diabetes care around monthly hormonal changes.
Montreal, QuebecAges 18–50 - NCT07037082Recruiting
Understanding menstrual cycles to improve women's health
This study tracks menstrual cycles and daily symptoms using a smart ring and home tests. It aims to better understand normal cycles and help detect health issues early.
MontpellierAges 18–39 - NCT07365904RecruitingPhase 2
Testing a new contraceptive patch for ovulation prevention
This trial tests a new contraceptive patch to see if it can prevent ovulation (the release of an egg). If you are a healthy woman looking for a non-hormonal birth control option, this study may be a good fit.
BerlinAges 18–35 - NCT07088952Recruiting
Ovulation trigger timing in natural cycle frozen embryo transfer
This trial compares triggering ovulation when the lead follicle is smaller versus larger than 17mm in a modified natural cycle. The goal is to see if timing the trigger differently improves pregnancy rates for women having a frozen embryo transfer.
Seville, SevillaAges 18–50 - NCT06636838Recruiting
Language and fertility treatment
This study looks at how language affects the experience of people getting fertility treatment. If Spanish is your preferred language, the researchers want to learn if speaking Spanish with your doctor helps you feel more comfortable and supported.
St Louis, MissouriAges 18 years+ - NCT07546136Recruiting
Fertility Preservation Before Cancer Treatment
This study helps people with cancer preserve their fertility (ability to have biological children) before undergoing cancer treatment that could affect their eggs or sperm. The trial compares two different hormone-injection methods to prepare eggs for freezing.
Bologna, BolognaAges 18–46 - NCT07255911Recruiting
Comparing two medicines for ovulation in PCOS
This study tests if adding cabergoline to letrozole works better than letrozole alone to help women with PCOS ovulate. It may help participants who have not had success with standard treatments.
Dhaka, ShahbagAges 18–35 - NCT07028710Recruiting
Progesterone changes after hCG-triggered ovulation in natural cycles
This study looks at how progesterone levels change in the early part of the luteal phase (after ovulation) when ovulation is triggered by an hCG injection in a natural cycle. It may help women undergoing routine ovulation induction understand how their body responds.
MontpellierAges Any age - NCT07703488Recruiting
Dydrogesterone for abnormal uterine bleeding in teens
This trial tests if dydrogesterone, a hormone pill, can safely help teenagers with heavy or irregular periods. If you or your child have had unusual bleeding that isn't caused by pregnancy or other medical issues, this study may provide treatment options.
Guangzhou, GuangongAges 10–19 - NCT04196595Recruiting

Boston, MassachusettsAges 18 years+ - NCT04650880Recruiting
Vitamin D study for irregular periods from PCOS
This trial studies whether taking vitamin D can improve ovulation (the release of an egg) in people with PCOS who have long, irregular menstrual cycles. It may help some participants have more regular ovulation and cycle timing, but you would be monitored with vaginal ultrasound and blood tests.
Hong KongAges 18–40 - NCT07699224Recruiting

MadridAges 18–45 - NCT05819853RecruitingPhase 3
Semaglutide to help restart periods in PCOS
This Phase 3 study tests whether semaglutide can help people with polycystic ovary syndrome (PCOS) start ovulating and having more regular periods. You may join with or without metformin, and contraception rules are important because the medicine must not be used during pregnancy.
Aurora, ColoradoAges 12–35 - NCT05181748RecruitingPhase 2/Phase 3
Platelet-rich plasma into ovaries for low egg response
This trial tests whether injecting your own platelet-rich plasma (PRP) into the ovaries can improve egg production in people who don’t respond well to fertility stimulation. It may help some “poor responders” get more usable eggs for IVF.
Athens, AtticaAges 35–47 - NCT06793904Recruiting
Comparing two ways to measure insulin resistance in PCOS
This study compares two methods (HOMA1-IR and HOMA2-IR) of measuring insulin resistance to see which one better predicts whether women with PCOS will ovulate after treatment. It aims to find a simple blood test that could help guide fertility treatment.
CairoAges 18–35 - NCT07159880Recruiting
