Residual follicle is the term given to the structure remaining in the ovary following a process of stimulation, whether this has been for insemination or during a cycle of in vitro fertilisation (IVF). Diagnosis is generally carried out using ultrasound imaging. On the whole, before embarking on a course of ovarian stimulation, a basal ultrasound scan is carried out. The aim is to check that the ovary is resting. In other words, that it has antral follicles measuring under 10 millimetres in length. Once the procedure has been carried out (whether this be insemination or ovarian puncture followed by transfer), if the attempt has unfortunately been unsuccessful, the patient is once again evaluated during the next menstrual cycle in order to see if a new course of treatment can begin. It is during this evaluation that a residual follicle can appear. We can find follicles that ought to be small during this stage. However, some are actually already over 10 millimetres in length. If the follicle is between 3 and 5 centimetres long, it is known as a residual cyst. Its aetiology is associated with the absence of ovulation in the follicle during the stimulation cycle or the presence of smaller follicles that continue to grow and remain until the next period.
