1860 T. H. Tanner On Signs & Dis. Pregnancy i. 7 The term pseudo-pregnancy is also sometimes applied to diseases which simulate pregnancy.

1893 T. M. Madden Clin. Gynæcol. xl. 463 In cases of pseudopregnancy we frequently find all the general symptoms of pregnancy counterfeited with an exactitude that might well seem marvellous if we did not take into consideration the circumstances.

1979 Frederick (Maryland) Post 19 June b11/2 A false pregnancy is also called a pseudopregnancy... A woman undergoes all the changes we customarily expect with a normal pregnancy.

1993 Acta Endocrinologica 129 Suppl. 38 The underlying mechanism of such a psychosomatic reaction, a typical example of which is pseudopregnancy, may be an extemporaneous activation of a neuroendocrine ‘maternal subroutine’ characteristic of pregnancy.

2. Zoology and Veterinary Medicine. A condition characterized by changes in the reproductive organs (and often behavioural changes) similar to those of pregnancy, which can occur in female mammals as part of a normal or abnormal oestrus cycle or after an unsuccessful mating; an instance of this. Also called false pregnancy.

1913 Hill & O'Donoghue in Q. Jrnl. Microsc. Sci. 59 135 As the œstral cycle in Dasyurus differs considerably from that of the Eutherian mammal, it has been found necessary to introduce two new terms, viz. Post-œstrus, to designate the period which intervenes between œstrus and ovulation; and Pseudopregnancy, to designate the period which, in the non-pregnant animal, follows ovulation, and in which the changes in the ovary, mammary glands and uteri are essentially similar to those in the pregnant female.

1940 Endocrinology 27 125 We produced pseudopregnancy [in mice] by three methods. (a) Females obtained from a low fertility group were allowed to copulate frequently but did not become pregnant. (b) Females were mated with vasectomised males. (c) Females were stimulated daily on the cervix uteri with a glass rod.

1970 W. B. Yapp Introd. Animal Physiol. (ed. 3) viii. 293 In those animals, such as mice, in which there is scarcely any pseudopregnancy, the corpora lutea develop very little and soon degenerate unless copulation occurs.

1981 J. Halliday & J. Halliday in K. Thear & A. Fraser Compl. Bk. Raising Livestock & Poultry iv. 94/2 Goats occasionally have pseudopregnancies, commonly termed as cloudbursts. The goat, either mated or unmated, will consider that she is in kid.
