Follicular monitoring explained

Follicular monitoring is a series of pelvic ultrasound scans across a cycle when a fertility specialist needs to see how ovarian follicles are growing. The calendar is set by that clinician’s protocol, not by the imaging centre alone.

Why serial visits

A single scan is a snapshot. Serial measurements show the trend — information used to time medicines or procedures. Missing a scheduled day can reduce the value of the series; call if you must reschedule.

Transabdominal vs transvaginal

Depending on clinical need and body habitus, one or both approaches may be used. Staff explain the steps; a chaperone policy and privacy are maintained.

Preparation

Often little fasting is required. A partially full bladder may help transabdominal views. Wear comfortable clothing and arrive on time — slots are tightly scheduled in monitoring programmes.

After each visit

Measurements go to your fertility doctor for decisions.
