title: Steroid concentrations in rabbit oviducal fluid during oestrus and pseudopregnancy.
abstract: The concentrations of progesterone and oestradiol in the oviducal fluid during oestrus and pseudopregnancy were measured. Progesterone concentrations ranged from 0.55 +/- 0.17 ng/ml during oestrus to a maximum of 2.86 +/- 0.82 ng/ml on Day 12 of pseudopregnancy. Serum progesterone concentrations were similar to those found in oviduct fluid during oestrus, but by Day 12 serum levels had risen to 14.13 +/- 1.97 ng/ml. Daily oviducal fluid oestradiol values ranged from 48.3 +/- 6.4 pg/ml to 119.7 +/- 23.6 pg/ml and were similar to serum concentrations.
