Female infertility

This trial tests whether an oral medication called linzagolix can replace daily injections used to prevent premature ovulation during in vitro fertilization (IVF). The study compares the number of mature eggs retrieved in women taking the pill versus those receiving standard inje…

This phase 3 trial investigates whether taking progesterone during the luteal phase of the menstrual cycle can increase the chance of a live birth for couples with unexplained infertility. Participants take either progesterone or a placebo twice daily for up to six months while t…

This study tests whether transplanting ovarian tissue from a sister can restore fertility and hormone production in women with premature ovarian failure (early menopause). Ten women will receive tissue from their non-identical sister, along with immunosuppressive drugs to prevent…

This study tests whether taking linzagolix (Yselty) for 3 to 6 months before an embryo transfer can improve live birth rates in women with adenomyosis who have experienced repeated implantation failure. Adenomyosis can make the womb lining less receptive to embryos, even when the…

This trial tests whether a single infusion of granulocyte colony-stimulating factor (G-CSF) into the uterus can improve pregnancy outcomes in women with thin endometrium (uterine lining) undergoing frozen embryo transfer. Thin endometrium can reduce the chance of pregnancy. The s…

This trial investigates whether giving obese women with polycystic ovary syndrome (PCOS) a GLP-1 receptor agonist (a drug that helps control appetite and blood sugar) along with healthy lifestyle education for 12 weeks before starting fertility treatment can improve their chances…

This study tests whether infusing a woman's own platelet-rich plasma (PRP) into the uterus can improve the uterine lining in women with a thin or unresponsive endometrium and a history of failed embryo transfers. About 80 women will receive either standard hormone therapy alone o…

This trial tests two ways of giving estrogen to girls and young women with Turner syndrome to help them start puberty. Participants will be randomly assigned to use either an estrogen gel applied to the skin or an estrogen tablet taken by mouth for 19 months. The study will compa…

This study tests whether a lower daily dose (150 IU) of follicle-stimulating hormone (FSH) is as effective as a higher dose (225 IU) for women with normal ovarian reserve undergoing IVF. The main goal is to see if the lower dose leads to similar live birth rates while possibly re…

This early-stage study tests a new drug called YB-1113 for women with premature ovarian insufficiency (early menopause). The goal is to see if it is safe and can help restart ovarian function, potentially allowing women under 40 to become pregnant. Only 6 participants will receiv…

This study aims to develop a non-invasive diagnostic test for endometriosis, a painful condition affecting 1 in 10 women. Researchers will combine AI-enhanced ultrasound with blood, saliva, and tissue markers to detect the disease without surgery. 365 women aged 18-45 with suspec…

This study tests whether a 12-week program of diet changes, supplements, exercise, and better sleep can improve fertility scores in women aged 20-40 who show early signs of fertility decline. Researchers will enroll 384 women across six medical centers in China, using the OvaRePr…

This study tests a mobile health app called OPUCARE designed to support women with infertility who are about to undergo egg retrieval. The app provides medication reminders, treatment information, side-effect tips, and motivational messages. Researchers want to see if using the a…

This study tests a web-based mind-body awareness program for women undergoing infertility treatment. The program includes education and relaxation practices over 3 sessions in 2 weeks. Researchers will measure if it improves fertility awareness and feelings of preparedness in 78 …

This pilot study tests a 4-week program based on acceptance and commitment therapy (ACT) for women who have experienced a miscarriage, stillbirth, or newborn death within the past year. The program includes six sessions plus a booster, combining in-person and video meetings. Rese…

This study looks at whether a gamified healthy lifestyle training program can help women going through fertility treatments (like IVF) adopt healthier habits and feel more in control. About 105 women will be split into three groups: one gets the game-like program plus a booklet, …

This study tests whether preparing the uterus for frozen embryo transfer with a completely natural cycle or a modified cycle (with ovulation-triggering medication) works better. It also looks at adding letrozole tablets early in the cycle. About 120 women undergoing IVF will be r…

This study tests whether intravenous lidocaine or magnesium sulfate can better stabilize blood pressure and heart rate as women wake up from general anesthesia during infertility-related laparoscopic surgery. Sixty-nine women will be randomly assigned to receive one of the two dr…

This study follows babies and young children (up to age 5) who have a genetic diagnosis of ataxia telangiectasia (A-T), a rare disease that affects movement and immunity. Researchers use brain and lung scans, blood tests, and movement analysis to spot early signs of disease progr…

This study explores whether ovulation can be detected using non-invasive methods like saliva, hair samples, and smartwatch data instead of standard blood tests. Researchers will monitor 30 women with regular menstrual cycles over three cycles, collecting saliva and hair for proge…

This study looks at women with diminished ovarian reserve (DOR) — a condition where the ovaries have fewer eggs, making IVF harder. Researchers are examining specific RNA molecules in the fluid around eggs to see how they relate to egg quality and embryo development. The goal is …

This large observational study will follow 4,000 young cancer survivors (ages 15-39) across Europe to understand how different cancer treatments impact fertility, hormone function, and pregnancy outcomes. Researchers will also evaluate the safety and success of fertility preserva…

This study will follow 3,000 young women (ages 15-39) with cancer to understand how treatments like chemotherapy and immunotherapy impact their fertility, pregnancy outcomes, and quality of life. Researchers will also look at the safety and success of fertility preservation metho…

This study looks at whether transferring an embryo on day 2 or day 3 after fertilization leads to more live births in women aged 35 or older with low ovarian reserve. About 470 women will be randomly assigned to one of the two transfer times. The goal is to find out which timing …

This study looks at how the size and number of ovarian follicles (fluid-filled sacs containing eggs) on the day of the trigger shot affect how many eggs are retrieved during an IVF cycle. Researchers will measure follicles using ultrasound in 60 women aged 18-35 undergoing ICSI. …

This study looks at 100 women undergoing fertility treatment to understand why some experience repeated implantation failure or pregnancy loss. Researchers will compare immune cells and microbes in the uterus of affected women versus those without such history. The goal is to fin…

This study will test a computer model that predicts infertility risk in women with uterine fibroids. Researchers will follow over 7,000 women aged 20-50 who want to conceive and have fibroids. The goal is to see if the model can accurately identify who might struggle to get pregn…
