The Role of the Conceptus in the Control and Maintenance of Pregnancy

  • Conference paper
Mammalian Reproduction

Abstract

The profound endocrine change that characterises pregnancy in most mammals is dependent upon an early maternal response to the presence of a conceptus in the uterus. It is with the mechanisms underlying the relationship between the mother and conceptus, and in particular with the way in which the conceptus acts to convert the corpus luteum of the cycle to one of pregnancy, that this paper will be concerned. The subject will be approached in a comparative manner using three species, namely the human and rhesus monkey on the one hand and sheep on the other as examples, since these represent extremes in the endocrine spectrum when considered in terms of the way in which the conceptus acts on the maternal organism. Reviews by PSYCHOYOS (1967), GREENWALD and ROTH- CHILD (1968), MOOR (1968a, b) and SHORT (1969) provide recent detailed information on the relationship between the conceptus and ovaries in a variety of Eutherian mammals.
