The aim of this study was to make a conclusion about aplicability of two differnet gonadothropins in COS (rFSH versus HP-hMG). he primary conclusion for the success as a result of COS are the mean number of retrived oocytes, mature oocytes, fertilization rate, mean number of quality embrios, and criopreverzed embrios. he secondary conclusions were clinical pregnancy rate and delivery rates. Methods: The study was a retrospective case-control study. A total of 1238 fresh, non donor, IVF cycles with COS were analyzed, but to minimize the bias, only the first cycle for each patient below 40 years old, in that period was analyzed. his selection composed the group of respondents that was analyzed which in total amounted to 760 patients.( rFSH = 422, HP-hMG = 338). he patients underwent COS by long luteal protocol using two different inducers of COS (rFSH and HP-hMG). Results: he average starting dose of rFSH used was significantely lower (152.7±41.1IU), whereas with HMG it was (228.8±68.7 IU, p=000000). he average number of IU gonadothropin used in therapy, statistically highly is significantly lower when r-FSH is used as an inducer. (1639.2 ± 476.9 IU, rFSH vs 2356.4 ± 955.1IU, HP-hMG, p <0.001). We received significantly higher average number of oocytes and mature oocytes in the group of r--FSH (oocytes; rFSH v HP-hMG--11.8 ± 7.1 v 10.7 ± 6.5, p = 0.028 ; mature oocytes: rFSH v HP-hMG 9.9 ± 6.2 v8.7 ± 5.5 p = 0.009). However, we did not find a significant difference in the use of the COS inductors regarding the clinical pregnancy rate (rFSH v HP-hMG 49.5% vs 48.9% p=0.92) and delivery rate (rFSH vs HP-hMG 42.9% vs 43.4% p=0.96). Conclusions: Our study showed that rFSH is more powerful and more applicable in individualized dosing then HP-hMG and brings better results from COS (more oocytes, more matured oocytes). Key words: Controled ovarian stimulation (KOS), rekominant folikulostimulative hormon (rFSH), high purity human menopausal gonadothropin (HP-hMG), intracitoplasmic sperm injection (ICSI), retrived oocytes.

    BACKGROUND: It is a common practice to repeatedly test the level of basal FSH early in the cycle and to start IVF treatment only when the FSH level is below a certain threshold value. This is based on the idea that these women will respond better to ovarian stimulation when the basal FSH level...
