Comparing pregnancy rates with nasal spray versus progesterone after frozen embryo transfer
Part of Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Are between 18 and 40 years old
- Have a body mass index (BMI) between 18 and 35

- Do not have endometriosis, uterine abnormalities, or a blocked fallopian tube
- Do not have nasal congestion or other breathing issues that would block a nasal spray

This study compares two forms of vaginal progesterone used to prepare the uterus for a frozen embryo transfer (FET). It may be a good option if you are already prescribed one of these progesterone regimens and are planning a single embryo transfer.
This study looks at how progesterone levels around the time of a frozen embryo transfer might affect the chance of a successful pregnancy. Participants will have their transfer done as usual, and researchers will measure progesterone levels to see if they relate to pregnancy outcomes.
This study compares two types of natural cycle preparation for frozen embryo transfers to see which leads to more pregnancies. It may be a good fit if you are using your own eggs, have regular cycles, and are planning a frozen embryo transfer.
This trial explores how natural uterine contractions affect pregnancy success in women using hormone therapy for frozen embryo transfer. It may help doctors understand if uterine activity influences implantation.
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.
This study looks at whether the level of progesterone, a hormone that helps prepare the uterus for pregnancy, on the day of embryo transfer affects the chance of a successful pregnancy in women using frozen embryos. It may help doctors understand if adjusting progesterone could improve outcomes.
