[Histological findings on the uterus of gilts following synchronized ovulation].

Histological studies were undertaken with the view to testing uterus structure and function of gilts following synchronised ovulation by means of different PMSG doses. All proband groups received 500 I.U. HCG. All histomorphological, histochemical, and histometric checks revealed 500 I.U. PMSG to be too low a dosage, whereas the optimum amount was found to be between 750 and 1,000 I.U. PMSG. The uterine glands of all treated animals in all three groups were less favourably developed than those of the untreated controls. The best morphologico-histochemical pattern was observed following administration of 750 I.U. PMSG.
