INFERTILITY, FEMALE

This study compares a longer course of the fertility drug Clomid against the standard short course for women with diminished ovarian reserve undergoing IVF. The goal is to see if the extended protocol leads to more mature eggs retrieved while reducing the number of injections and…

This phase 3 trial compares two ways to prepare the womb lining for a frozen embryo transfer: a modified natural cycle using progesterone only, versus standard hormone replacement therapy. The study will enroll 336 women aged 21-44 with regular cycles to see which method leads to…

This study offers girls facing fertility-threatening medical treatments the option to freeze their ovarian tissue for future use. Up to 40 participants will have a small piece of ovary removed laparoscopically and stored. The goal is to see how many choose this option and at what…

This study looks at whether giving a GnRH agonist before a frozen embryo transfer can help women with endometriosis or adenomyosis get pregnant. About 180 women aged 18 to 36 will be randomly assigned to receive either standard hormone support or standard support plus one or two …

This study tests a milder form of IVF called CAPA in-vitro oocyte maturation (IVM). Instead of giving women strong hormones to stimulate egg growth, eggs are collected early and matured in a lab. The goal is to reduce side effects and costs for women with infertility or those pre…

This study tests whether taking a low dose of the hormone hCG for 8 weeks before IVF can increase the number of eggs retrieved in women with diminished ovarian reserve. About 80 women will be randomly assigned to receive either hCG or a placebo. The main goal is to see if hCG lea…

This study compares a single injection of corifollitropin alfa (Elonva) to daily shots of follitropin beta (Puregon) for ovarian stimulation in egg donors. Both groups also take medroxyprogesterone acetate to prevent early ovulation. The goal is to see if the simpler one-shot app…

This study tests whether tadalafil, a drug that improves blood flow, can thicken the uterine lining and increase pregnancy rates in women with unexplained infertility. About 100 women who have good-quality frozen embryos will take tadalafil before embryo transfer. The main goal i…

This study looks at whether a smartphone app with daily mindfulness exercises can help reduce anxiety and improve quality of life for women undergoing IVF. About 150 women will either use the app for 15 minutes a day or receive standard care. Researchers will measure anxiety, dep…

This study tests whether taking Gushen Antai pills, a blend of 10 herbs, can increase the chance of an ongoing pregnancy (past 12 weeks) in women with normal ovarian reserve who are undergoing IVF. 800 women will be randomly assigned to receive either the herbal pill or a placebo…

This study tests whether a 9-step mindset management program called Organic Conceptions can reduce stress in women struggling with infertility. About 66 new patients at a fertility clinic will either take the program or serve as a control group. Researchers will measure stress le…

This study is looking at whether women with lower ovarian reserve (fewer eggs) have had more early miscarriages in the past. Researchers will measure ovarian reserve with a blood test (AMH) and an ultrasound (antral follicle count) in over 2,000 women seeking fertility care. This…

This study tracks immune-related substances in the blood of 40 women undergoing a frozen embryo transfer. Researchers want to see how these markers change before and after the transfer, and whether they relate to pregnancy success. The goal is to better understand the role of the…

This study follows women aged 18 to 44 who are trying to conceive at a fertility clinic. Researchers want to learn how lifestyle habits like sleep, nutrition, and physical activity before pregnancy affect the chances of having a baby. Participants will be followed for up to 25 ye…

This study looks at whether measuring telomeres—parts of our cells linked to aging—can help explain why some women still can't get pregnant even after fertility treatments. Fifteen women aged 25 to 42 will get blood tests to check their biological age, then receive a personalized…

This study aims to better understand cervical mucus and find biological markers that could help diagnose or predict reproductive problems like infertility. Researchers will use infrared spectroscopy to analyze mucus samples from 24 women—some healthy and some with unexplained inf…

This study looks at immune cells in the womb lining and blood of women with unexplained infertility or repeated miscarriages, compared to fertile women. Researchers want to see if differences in these cells help explain why some women have trouble getting pregnant. The study invo…

This study looks at how physical activity, fitness, stress, and sleep affect pregnancy rates in women receiving fertility treatments like IVF or IUI. Researchers will track 115 women aged 18-43 to see if being more active improves their chances of getting pregnant. The goal is to…

This study looks at how women getting infertility treatment feel about artificial intelligence and how that relates to their anxiety and quality of life. About 191 women aged 18-45 who are currently undergoing treatment will answer surveys. The goal is to understand if attitudes …

This study watches blood sugar levels in 100 women getting fertility treatments like IVF. Participants wear a continuous glucose monitor to track sugar changes. The goal is to see if these changes affect pregnancy results. This is an observation-only study, not a treatment.

This study looks at how different ovarian stimulation protocols affect blood clotting in 300 infertile women, including those with endometriosis. Researchers will measure clot formation and breakdown before and after treatment. The goal is to understand which protocols may be saf…

This study looks at whether chlordecone, a pesticide still present in the environment in Guadeloupe, is linked to fertility problems in women. Researchers will measure a key fertility hormone (AMH) and count egg follicles in 634 women seeking fertility treatment. The goal is to u…

This study looks at whether levels of Anti-Müllerian hormone (AMH) in the fluid around a woman's eggs can predict if an embryo has the right number of chromosomes. Researchers will collect fluid from one follicle in each ovary during egg retrieval in 300 women undergoing IVF. The…

This study looks at two ways to fertilize eggs with frozen donor sperm: ICSI (injecting a single sperm into an egg) and conventional IVF (mixing eggs and sperm in a dish). About 95 women without male fertility issues will have their eggs split into two groups, one fertilized with…
