Effect of the FSH dose in superovulatory protocols on ovulatory follicle dynamics in ewes.

The objective of this study, was to evaluate the exogenous FSH dose effect on gonadotrophic treatment over ewes ovulatory follicle dynamics.

Follicular population on the estimation of the superovulatory response in Santa Ines sheep.

The aim was to verify the correlation between follicular population count, superovulatory response and the recovery of viable structures in the in vivo production of sheep embryos. In conclusion, there is a median correlation between follicular population observed by ultrasonography and viable recovered structures after superovulation protocol. Therefore, this tool is not indicated as a screening tool, alone, in the selection of Santa Inês sheep embryo donors.
