  42. 42. Mean ovarian volume <3 cm3: poor response to HMG very high cancellation rate during IVF (Lass et al, 1997) Mean maximum ovarian diameter measured in the largest sagittal plane good estimation of ovarian volume >3.5 cm: increase risk of OHSS <2 cm: decreased ovarian reserveAboubakr Elnashar
  43. 43. AFC: Resting follicles. Total number of follicles 2–8mm counted in both ovaries A threshold of 5 AF (2-5 mm) have the lowest error rate for the prediction of poor response (Bancsi et al.,2004) Aboubakr Elnashar
  44. 44. Batista et al. 2012 ovarian response prediction index (ORPI) multiplying the AMH(ng/ml) level by the number of antral follicles (2–9 mm),and the result was divided by the age (years) of the patient. Aboubakr Elnashar
  45. 45. Aboubakr Elnashar
  46. 46. Early in the menstrual cycle. No medications being given. 9 antral follicles. The ovary has normal volume (30X18mm). Expect a normal response to injectable FSH. Aboubakr Elnashar
  47. 47. only 1 antral, other ovary had only 2 antrals Ovarian volume: low D3 FSH: normal Attempts to stimulate ovaries for IVF were not successful Aboubakr Elnashar
  48. 48. At the beginning of a menstrual cycle, irregular periods, No medications being given. Antral follicles:16 are seen in this image. Ovary had a total of 35 antrals (only 1 plane is shown). This is PCO with a high antral Ovarian volume= 37 X19.5mm "high responder" to injectable FSH drugs. Aboubakr Elnashar
  49. 49. POF. Only the stroma of the ovary is identified. A very few follicles of less than 1 mm on the inferior aspect of the ovary. Aboubakr Elnashar
  50. 50.  Diagnosis of Spontaneous Ovulation 1. Mature F. (contain mature oocyte) = 17 – 25 mm (Inner dimensions) 2. Deflation of the mature follicle 3. Intra peritoneal fluid -Normal: 1-3 ml -With ovulation: 4- 5 ml 4. CL: 4-8 days after ovulation • Irregular thick wall . • Hypoechoic • May contain internal echos (hge.) • 15 mm Aboubakr Elnashar
  51. 51. Mature follicle Aboubakr Elnashar
  52. 52. Atretic follicle of preovulatory diameter. thin follicle walls and sharp transition at the fluid-follicle wall interface. The shape of the large atretic follicle is compromised by small peripheral follicles.Aboubakr Elnashar
  53. 53. Corpus albicans resulting from regression of a luteal structure from a previous cycle. hyperechoic structures within the ovary and they may occasionally appear to be more pronounced owing to the presence of surrounding follicles. Aboubakr Elnashar
  54. 54. Early Corpus Luteum. The site of rupture of the dominant follicle soon after ovulation appears as a collapsed cystic structure (arrow) on the ovary (o). u, uterus. Corpus Luteum–Hypoechoic Solid Appearance. The corpus luteum appears as a hypoechoic solid mass (arrow) on the right ovary (o) on this transvaginal image.Aboubakr Elnashar
  55. 55. Corpus Luteum–Thick-Walled Cyst Appearance. Transvaginal scan shows an anechoic ovarian cyst (between calipers, +, x) with moderately thick walls. Corpus Luteum–Thin-Walled Cyst Appearance. This corpus luteum (arrow, between cursors, +, x) has a thin wall and contains anechoic fluid. Aboubakr Elnashar
  56. 56. Corpus hemorrhagicum thick walls of peripheral luteal tissue and a central hemorrhagic clot with an interspersed fibrin network. Aboubakr Elnashar
  57. 57. Failure of ovulation and development of “cystic” follicle. The follicle typically grows larger than the mean preovulatory follicle diameter of 23 mm, thin atretic follicle walls and small flecks of particulate matter are frequently seen in the lumen or aggregated at the side of the structure.Aboubakr Elnashar
  58. 58. Hemorrhagic anovulatory follicle. Extravasated blood and an interspersed fibrin network are observed within the lumen. The walls of this structure are thin, echoic, and do not have the appearance of luteal tissue. Aboubakr Elnashar
  59. 59. Endometrioma Hyperechoic wall foci (in35%) Cysts With Low-level Echoes Hemorrhagic cyst Lacelike internal echoes (in 40%) Teratoma Regional bright echoes (in 97%) Aboubakr Elnashar
  60. 60. Endometrioma. Sagittal TVS an ovarian mass with multiple fine internal echoes (arrows) and several hyperechoic mural foci (arrowheads). Aboubakr Elnashar
  61. 61. Ovarian endometrioma (A, B). The structure is hypoechoic and exhibits low amplitude uniformly distributed echotexture in the cavities of the cysts. Aboubakr Elnashar
  62. 62. PCO: Rotterdam, 2004 At least one of the following 12 or more follicles in each ovary measuring 2 to 9 mm in diameter or Ovarian volume >10 cm3. Only one ovary meeting these criteria is sufficient for diagnosis. The follicle distribution & increase in stromal echogenecity & volume are not required for diagnosis. Absence of mature follicle Aboubakr Elnashar
  63. 63. Technical recommendation 1. Regularly menstruating females should be scanned between days 3-5 Oligo-/ amenorrhoeic should be scanned either at random or between days 3-5 after progesterone – induced bleeding 2. If there is evidence of a dominant follicle >10 mm or a corpus luteum, the scan should be repeated the next cycle. 3. Ovarian volume= 0.5X length X width X thickness Aboubakr Elnashar
  64. 64. PCO Multiple peripheral subcentimetric follicles (arrow). Aboubakr Elnashar
  65. 65. Subtypes of PCO: The images exhibit quite different appearances in the size and distribution of follicles. A recent corpus luteum is clearly visible in the ovary in panel (D). Aboubakr Elnashar
  66. 66. III. Tubal factor 1.Tubal patency: SIS 2. Hydrosalpinx: decrease the chance of implantation with IVF Aboubakr Elnashar

  74. 74. I. Ovarian induction/IUI Monitoring: • Base line scan on D2 or 3 of the cycle • US on D8 of stimulation: Follicles: number & size Endometrium: thickness & appearance • Repeat /2-3 days depending on the size of leading follicle, until it is 18 mm Aboubakr Elnashar
  75. 75. II. IVF 1. U.S between D10 & 15 of preceding IVF cycle: Uterus: fibroid Ovaries: size, PCO, ovarian cyst Tubes: hydrosalpinx Aboubakr Elnashar
  76. 76. 2. COH: a. Confirm down regulation: Thin endometrium: <4 mm, quiescent ovaries containing only small follicles b. Follicular development & endometrial thickness: D6 stimulation Repeat daily or alternate day depending on response Aboubakr Elnashar
  77. 77. US guided oocyte retrieval. The oocyte collection needle is visualized entering into a large follicle. Etching around the tip of the needle enhances its visualization. 3. Oocyte retrieval: Aboubakr Elnashar

  79. 79. Aboubakr Elnashar
  80. 80. Embryo transfer is enhanced by the use of ultrasound guidance to place the embryos at the optimal uterine location. The small hyperechoic areas distal to the catheter tip represent microbubbles of air expelled from the transfer pipette and serve to visualize embryo placement.Aboubakr Elnashar
