Baseline scan

The scan at the start of a treatment cycle before stimulation.

Testing

A baseline scan, usually early in the cycle, checks that the ovaries are quiet, counts antral follicles and confirms the lining is thin. It makes sure there are no cysts that would interfere with stimulation, and it is the point at which your clinic confirms your starting dose.

Also known as: day 2 scan, start scan
