Hi , my height is 154c, weight-64.2kg, right ovary vol-5.6cc with dominant follicle of sie 10*8mm, left ovar volume is 9.6cc. Left ovary is normal in size with multiple small follicles arranged pripherally with central echogenic stroam. No follicular differentiation noted. My cycle is regular with 24 days and i bleed for 5-6 days during menstruation. Is it normal to have regualr periods and cysts? and do cysts be formed only in one ovary?
