Is done to measure the growth of follicles. Type and doses of drug is calculated on individual basis to obtain optimum ovulation and prevent side-effects. Usually folliculometry is done by transvaginal ultrasound scanning. [two to three times or more during a treatment cycle]  and some times by measuring hormones (E2) in a blood sample. When the leading follicle measures > 18mm in diameter and the endometrium is well developed, an HCG injection is given to trigger maturity of the oocyte and ovulation.
