Follicles 17*11mm with 6.5mm thick lining have a lower chance of getting pregnant.
Under normal circumstances, a woman’s follicle needs to develop to 18mm or more to be a mature follicle, and the mature follicle will rupture and ovulate under the action of luteinizing hormone. If the egg and sperm combine to form a fertilized egg, the thickness of the uterine lining that is suitable for attachment is 8~12mm.
Therefore, if the dominant follicle is 17*11mm at ovulation the possibility of ovulation is small, plus the thickness of the endometrium is also not suitable for fertilization of the egg to bed, so the chances of pregnancy are low.
If ovulation has not yet occurred, the dominant follicle and the endometrium may continue to grow and meet the requirements for conception. Moreover, a woman’s ovulation period is affected by environmental, psychological and other factors, and may be somewhat earlier or later. Whether pregnancy is possible in the above cases should be considered by a medical professional according to the patient’s condition.
