Follicle study
A few short ultrasounds around ovulation, so we can see how your ovaries are responding in real time.
How it works
Is ovulation happening as it should?
A follicle study is a series of ultrasounds used to determine whether ovulation is occurring properly. Over several days around ovulation, we measure follicle growth and confirm that the follicle ruptures normally and releases an egg.
Each ultrasound is done in our office and takes just a few minutes. A follicle study is an important part of a fertility evaluation, and it is also used to see how you respond to fertility medications.
How many appointments?
Most studies take three visits
1
Cycle day ~10
About two days before your expected peak day. We measure early follicle growth.
→
2
Cycle day ~12
Your expected peak (ovulation) day. We confirm the follicle has reached maturity.
→
3
Cycle day ~14
About two days after peak. We confirm the follicle ruptured and ovulation occurred.
These day numbers are a general guide only. Cycle length varies from woman to woman and month to month, so our team will adjust your exact appointment days based on your ongoing monitoring.
Good to know
What to expect
Why do I need one?
Your provider sees in real time whether a follicle is developing on schedule, whether it reaches a mature size, and whether ovulation occurs.
What happens at each visit?
Your provider or sonographer measures the developing follicle(s) and the thickness of your uterine lining. The scan takes just a few minutes, and you can return to your normal activities right afterward.
Do I need to prepare?
No special preparation is needed, and you do not need a full bladder. We simply ask that you arrive on time for your appointment window, since ovulation timing is precise.
What happens afterward?
Your provider reviews each scan the day it is done and messages you about next steps: another scan, taking medication, or waiting for a better moment in your cycle. At your follow-up visit, we review all your scans together with your history and any lab work.
