Oval follicles do not affect pregnancy because normal follicles are round or oval in shape, but oval in shape is less common, as long as the uterus and ovaries function normally, can discharge mature eggs, and there is no serious inflammation trouble usually can get pregnant normally. If the follicles are too large, oval or elongated, poor follicular morphology will affect the quality of the eggs, and the eggs will not survive long enough to get pregnant. Even if a poorly shaped egg is able to form a fertilized egg with sperm, the chances of malformation or stillbirth during development are higher. If you detect an oval follicle or other abnormal shapes, you need to check your health condition and prepare for pregnancy according to your doctor’s instructions.
