The number of ultrasounds required in a follicular study varies based on individual cycles, but typically 3-5 scans are performed from the 2nd day of the cycle until ovulation is detected.

The follicular study tracks the follicle growth and monitors:

• Endometrial thickness: The thickness of the uterine lining, which is crucial for embryo implantation.
• Follicle count: The number of follicles developing, which can indicate ovarian reserve and fertility potential.
• Ovulation timing: Determining the exact time of ovulation can help with conception timing or fertility treatments.
• Hormonal changes: Hormones like estrogen may be measured in some cases to further assess follicular development.

The size of the follicles is an important factor in ovulation. Monitoring follicle size helps doctors determine when ovulation is likely to occur and can assist in timing treatments like IUI or IVF.

When the follicle reaches the appropriate size (18-24 mm), ovulation is expected to occur in 12-36 hours. If you are undergoing fertility treatment, a trigger shot of hCG may be administered to induce ovulation. This helps to ensure the timing of ovulation aligns with IUI, IVF, or natural conception attempts.

Preparing for a follicular study generally involves the following:

• Following your doctor’s instructions: Your doctor will tell you when to start the study based on your cycle.
• Being on time for ultrasound scans: Timing is the key in follicular monitoring, so you may need to attend multiple appointments during your cycle.
• Informing your doctor of any fertility medications: Let your doctor know if you are taking medications like Clomid or injectable gonadotropins.
• Maintaining hydration: Drink plenty of water before your ultrasound to ensure better visibility.
