Follicle Tracking Ultrasound
About Follicular Tracking
Follicular tracking (monitoring) is an important part of a fertility treatment cycle, whether you are doing an intercourse cycle, intrauterine insemination (IUI), in-vitro fertilization (IVF), or egg freezing. A transvaginal ultrasound is performed during the menstrual and/or follicular phase(s) of your cycle to monitor the growth of your follicles and the thickness of your uterine lining. Ultrasound monitoring generally begins early in the cycle (depending on the type of treatment) and is repeated at regular intervals leading up to the day when the follicles appear mature. During the exam, you will see the sonographer record the number and size of each follicle. The doctor will use this information to help determine the best time to trigger you for an IUI or IVF procedure.
Follicular tracking appointments are in the mornings and are relatively short lasting about 10 to 15 minutes. The number of exams required during a cycle varies.
