SUMMARY

A modified venous outflow technique was used to measure ovarian blood flow in the rat. The rate of flow through the right ovary was 0·198 ± 0·009 (s.e.m.), 0·476 ± 0·076 and 0·958 ± 0·162 ml/min in six Day 0 (dioestrous), five Day 16 and six Day 22 pregnant rats respectively. The intravenous administration of 50 i.u. human chorionic gonadotrophin increased ovarian blood flow by 26 ± 4, 57 ± 19 and 46 ± 9% respectively, from 2 to 8 min after the injection. The present ovarian venous outflow results are substantially higher than those previously reported in the rat but agree with values determined with radioactive microspheres.
