Rarely one encounters patients with PCOS with>100 follicles /ovary.Stimulation protocols are very difficult for such ovaries with all or none phenomenon workingand whatever FSH dosage is given seems to be lost in the ocean of follicles.Here we report two such cases who were successfully stimulated and conceived.Initial stimulation in first case was cc50mgbdalong with 150iu FSHX3days increasing to 225 units for 6consecutive days without any evidence of DF.With a slight increase in e2 from 66to 99pg/ml 450iu of humog were given for 3 consecutive days when 3df’s were visualized on rt side &e2 increased to 999pg/ml &then step down to 5/4 humog with E2 2900pg/mlwith 10df’s on either a caberline dose was given from day of 10,000unit hcgand we retrieved 6 good oocyteswith 100%fertilization and patient conceived a singleton pregnancy &has an ongoing preg of 18wks.Conversely in the 2nd pt as we had a limitation of time schedule we started with CC +225 units FSH X3daysand increased to 375 units x2days yet no response &then gave 600iuhumog because of constraint of time and E2increased to 1461pg/ml with dfs appearing in lt ovary around 11mm mostly and 10mm on rtside and although initially tapered to 375/300iu since the big ovaries response was v slow we had only dfupto 14mm or smaller so had to increase to 600/450 iu in deadlinre of HCG and got e2 increasing from 2900 - 3500 -4500 although onpickup we has df’s 25 on rt side &retrieved 18folliclles and v small df’s o n lt side and no DF retrieved from lt side .Poor fertilization rate was seen10/18 with the rest 10 also blastomeres not equal and fragmentation observed.Patient conceived after 14days with a positive upt and bhcg-64iu but we await report of usg after 2weeks.Hence the importance of gradual stimulation but better than coasting/leaving on 200iu hcg where author observed all germinal vesicle stage oocytes
