Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether tracking FSH levels during ovarian stimulation can help predict how many eggs a woman will produce. Researchers will monitor 150 women undergoing IVF to find the ideal FSH range for better outcomes. The goal is to tailor hormone doses to each patient, potentially making treatment more effective and safer.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Gonal-f (gonadotropin)
What this could lead to
If successful, this could help doctors personalize FSH doses during IVF, potentially improving egg retrieval and reducing side effects.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to a clear dosing guideline, and results may not apply to all patients.
