Once the menstrual cycle is over, growth and maturation of ova starts. Somewhere in the middle of the cycle around 14th -16th day, ovulation occurs and released ova is picked up by Fallopian tube and is ready to be fertilized by sperm , hence occurs origin of life.
Follicular study is an ultrasonographic investigation done serially every 2nd or 3rd day starting generally from Day 6 or 8 of menstrual cycle. This study is deemed complete once it has detected ovulation.
