Thanks for the query.
No, follicular study
is not biopsy.
In follicular study the development of the ovarian follicle
will be observed through the ultrasound
You have to go for ultrasound examination on alternative days form around 12th day of the cycle.
After the ovum reaches the sufficient size, some doctors will give injection for release of the ovum.
Some may leave for natural release.
Then you have to plan unprotected intercourse
around this period, which will increase the chances of pregnancy.
