Abstract
Summary
The present study provides a comprehensive assessment of the dynamic changes that occur in the secretion of prolactin, LH and FSH during pseudopregnancy. Prolactin levels are elevated during the first 5 days of pseudopregnancy and suppressed during the remainder of the term. LH levels are suppressed during the duration of pseudopregnancy and show very little fluctuation. Finally, FSH levels, while lower than values of this hormone in proestrus, show a peak on Day 3 and a steady rise beginning Day 8 of pseudopregnancy.
