approximately 18mm
The ultimate goal is to have 2 or 3 follicles reach approximately 18mm in diameter. Once that is the case and once the lining is appropriately thick (>7mm), a patient is instructed to take the “trigger” medication. The “trigger shot” prompts mature eggs to be released in 36-40 hours.

How many eggs are good for IUI?
