Abstract: 

The 16 normal healthy cyclical dangi donors were synchronized by injecting 0.75 mg of Iliren 11 days apart and superovulated by using 200 to 400 mg of FSH (Folltropin-V) in 8 divided tapering doses, for 4 days at 12 hr. interval. Embryos were recovered on 7 day of estrus. The DPBS with 0.04% Bovine Serum Albumin and evaluated as transferable and nontransferable. The mean superovulatory response for the FSH dose 200, 360 and 380 was 4.53 ±0.60, 4.15 ± 0.90 and 2.93 ± 0.60, respectively. At the same time the viable embryo recovery was 2.53 ± 0.79, 1.15 ±0.78 and 0.16 ±0.73, respectively and total embryo recovery was 5.33 ±1.30, 4.23 ± 1.42 and 1.93 ± 00.58, respectively. It is observed that at lower dose of FSH 200 mg the superovulation was better leading to increased total and viable embryo recovery but statistically not significant.
