Most ovarian stimulation protocols in ruminants utilise pituitary extracts that contain FSH with varying amounts of LH contamination. Protocols utilising these extracts in sheep generally give superovulation responses that are highly variable in the range of 0-15 ovulations. The use of pure recombinant human FSH (rhFSH) is widespread in clinical medicine. The aims of the study are: a) to determine if rhFSH will induce superovulation in sheep and whether this differs in response to human menopausal gonadotrophin (HMG), which is more similar to pituitary extracts with an equal amount of LH to the FSH; b) to monitor the effect of the human FSH’s on the endogenous LH and FSH concentrations.
