Comparing two medications to stop early ovulation during IVF with embryo freezing
Part of Women’s health & pregnancy clinical trials.
This study compares two types of fertility medications (a natural progesterone injection versus a GnRH antagonist injection) to see which better prevents early ovulation during IVF when all embryos are frozen for later transfer. If you are freezing all embryos for medical or personal reasons, this trial may help improve your chances of success.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman aged 18 to 40.
- Your body mass index (BMI) is below 35.
- You have a good egg supply (confirmed by ultrasound or blood test).
- You are freezing all embryos for later transfer, not putting them back right away.
- You do not have severe endometriosis, a pituitary or hormonal condition, or severe male factor infertility.

This trial compares two doses of follicle-stimulating hormone (FSH) to find out which dose helps women with normal ovarian reserve have better IVF outcomes. It aims to improve the chances of a successful pregnancy.
This study compares two ways of giving fertility medication to stimulate the ovaries before retrieving eggs for IVF (in vitro fertilization). One method starts after ovulation and uses a drug called Elonva without a routine blocking medication, while the other is the standard approach starting early in the cycle. The goal is to see which approach leads to better outcomes for people undergoing IVF or ICSI (a procedure where a single sperm is injected into an egg).
This study compares two different ways to prepare the womb for transferring a frozen embryo, to see which approach works better. It aims to find the most effective method to help you have a successful pregnancy.
This study compares two types of ovarian stimulation protocols (PPOS and GnRH antagonist) for women undergoing IVF with a freeze-all embryo plan. It uses time-lapse imaging to see if one approach leads to better embryo development.
This trial compares two hormone treatment protocols used during IVF to see which one leads to more genetically normal embryos in women with polycystic ovary syndrome (PCOS). It may help women with PCOS have better chances of a successful pregnancy.
This trial compares two hormone protocols for ovarian stimulation in women having their first cycle—either to freeze eggs for fertility preservation or for IVF with genetic testing. The goal is to see which method leads to more usable eggs while being easier on the patient.
