Ultrasound Basics for You by Dr. Pankaj Talwar
Q- Why is ultrasound done?
  • To look for any disease in uterus, ovaries, tubes and pelvis. Which may cause Infertility.
  • Done to asses uterus for size position Anteverted (anterior tilting)/ Retroverted (posterior tilting)
  • Endometrial thickness (thickness of the uterine lining), Myometrium, cervix.
  • In Ovaries to look for size, volume and follicular number.
  • To look for any fluid in the pelvis (lower abdomen) which indicates infection or pelvic tuberculosis.
Q- How is it done?
  • It is done by two methods TAS (Transabdominal scan) TVS (Transvaginal scan)
  • TAS is done with full bladder abdominally; It is preferred in patients who have vaginismis, enlarged uterus or other pelvic masses.
  • TVS is done after emptying bladder by inserting probe gently inside vagina It is mostly preferred over TAS as it provides a clear view of the uterus, ovaries and other pelvic structure
Q- When it is done?
  • It is done usually with respect to fertility assessment on D2, D9 and D21. nd
  • D2 USG(2 day of the menstrual cycle ) is done to look for Antral Follicular Count (AFC) which predicts the fertility potential of the ovary and its response to treatment. Normal Antral Follicular Count (AFC) is 5-10 in each ovary of the size 2-9mm.
  • To look for any cysts (follicular, corpus luteal) from the previous menstrual cycle, endometrioma, dermoid cyst.
  • D9 USG(9 day of the menstrual cycle ) is done to look for Endometrial lining which is usually triple layered with good blood flow on using color Doppler, which indicates adequate Endometrial receptivity.
  • D21 USG(21 day of the menstrual cycle ) to look for secretory changes in Endometrium and rule out uterine anomalies.
