A follicle 20x13mm not round may conceive if the follicle is mature and able to be expelled, otherwise, conception will not be very likely. Follicle 20x13mm not round means that the follicle may not have reached a round or oval shape, but if it has reached the level of a mature follicle and is able to be discharged, and the egg combines with the sperm to form a fertilized egg, then conception is possible. If the follicle 20x13mm is not round and has not reached the level of a mature follicle, it will not normally be expelled and no fertilized egg will be formed, and conception will not be very likely. Women with follicles that are 20x13mm are required to undergo regular ultrasound monitoring of the ovaries under the guidance of a medical professional, as well as other ancillary tests, which can clarify ovulation and conception.
