WebGraafian (tertiary, mature) follicles are large preovulatory follicles which bulge from the surface of the ovary. Once the follicular antrum is formed, the oocyte is surrounded by a remnant of granulosa cells called the cumulus oophorus. The cells of the cumulus oophorus immediately adjacent to the oocyte are known as the corona radiata. WebThe total of 29 preovulatory IUI, and 221 postovulatory IUI couples were recruited. In postovulatory IUI, 5,000 IU of hCG was injected when dominant follicle reached 17 mm. The IUI was performed 36 to 40 hr afterward. In preovulatory IUI, hCG was in- jected and IUI was performed simultaneously when the dominant follicle reached the size.
