What is a clomid challenge test (CCT)?
A clomid challenge test (CCT) is one way of measuring ovarian reserve. It is done by having blood drawn for an FSH level on Day 3 of your cycle (day 1 is the first day of your period). You then take Clomiphene Citrate 100 mg (two 50 mg tablets) on days 5 through 9 of your cycle. A repeat FSH level is drawn on Day 10.
