Nafarelin nasal spray for egg freezing
This trial tests an intranasal spray called nafarelin to help mature eggs before they are retrieved and frozen. If you are already going through a fertility preservation cycle to freeze eggs, this study wants to see if this spray works as well as the usual injections.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman having a fertility preservation cycle to freeze your eggs
- You are using a progesterone-primed ovarian stimulation (PPOS) cycle with any standard fertility medications
- Your body mass index (BMI) is between 18 and 30

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.
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.
This study compares two ways of supporting the womb after a frozen embryo transfer: using a standard hormone (progesterone) or a nasal spray (GnRH agonist) that helps the body produce its own progesterone. It aims to see if the nasal spray can improve pregnancy rates.
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.
This trial compares two hormone injection protocols to help women with low egg supply grow eggs and collect eggs for IVF. If you qualify, your embryos will be frozen first (“freeze-all”) and then transferred later as one frozen blastocyst.
This trial tests whether giving a medication called a GnRH agonist (which affects hormones) before a frozen embryo transfer can improve the chances of pregnancy in women with infertility. It aims to see if this treatment helps the uterus accept the embryo better.
