Superimposed follicles are two follicles in close proximity to each other, and an ultrasound shows that the echoes of the two follicles are superimposed, possibly with a bit of squeezing or overlapping shadows, and often related to the angle of the ultrasound probe. The number of follicles may be slightly higher, especially if ovulation induction treatment has been given. Whether or not such a follicle ultimately leads to pregnancy is influenced by a number of factors, including the size of the follicle, the level of estrogen and progesterone in the body, ongoing monitoring of the follicle to see if it matures and is expelled, the quality of the sperm, and the state of the fallopian tubes and the condition of the lining of the uterus. Infertile women who monitor their follicles should not overstress themselves, as overstressing may affect their chances of pregnancy, and should follow their doctor’s instructions regarding follicle monitoring.
