Progesterone changes after hCG-triggered ovulation in natural cycles
Treatments studied
Part of Hormones & metabolism, Women’s health & pregnancy clinical trials.
This study looks at how progesterone levels change in the early part of the luteal phase (after ovulation) when ovulation is triggered by an hCG injection in a natural cycle. It may help women undergoing routine ovulation induction understand how their body responds.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have at least one follicle (egg sac) that is 14 mm or larger.
- Your uterine lining must be at least 6 mm thick.
- At the start of your cycle (day 1–4), your LH level was less than double the normal and your progesterone level was below 1.5 ng/mL.
- You are scheduled to receive an hCG shot (like Ovitrelle) to trigger ovulation as part of your regular treatment.
- You cannot be using any progesterone medication (vaginal, injectable, or synthetic) that might interfere with the study.

This trial tests whether giving extra progesterone injections after an embryo transfer can improve pregnancy outcomes for women who have low progesterone levels. It may help support the pregnancy in its early stages.
This trial tests whether a low dose of progesterone (a hormone) can help trigger ovulation in women who have trouble getting pregnant. It may offer a new option for women with infertility.
This study tests whether a progesterone vaginal insert can effectively trigger ovulation in healthy egg donors. It aims to provide a more comfortable option for the final step before egg retrieval.
This study tests how hormone levels (progesterone) change day to day in the lining of the uterus (endometrium) during an embryo transfer in a medicated cycle. The goal is to better time the transfer and improve success 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 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.
