This scan also helps in determining the timing of egg extraction based on the number of follicles present.

Follicular scans are usually recommended to

  • study the number of follicles
  • observe the changes in the uterine lining
  • determine the ovulation period so that intercourse/IUI/IVF procedure can be timed accordingly
  • understand whether the dosage of any fertility drugs given is appropriate or needs to be changed
