cyesio-, cyes-, cyo- +
(Greek: to be pregnant; pregnancy)
2. Implantation and subsequent development of a fertilized ovum outside the cavity of the uterus.
3. Gestation elsewhere than in the uterus (as in a fallopian tube or in the peritoneal cavity); also called: ectopic gestation, extrauterine gestation, extrauterine pregnancy.
2. The fertilization and subsequent development of an ovum when a fetus is already present in the uterus, as a result of fertilization of ova during different ovarian cycles, yielding fetuses of different ages.
This is possible only when there is a double uterus, or where menstruation persists up to the time of the second impregnation.
2. A gestation elsewhere than in the uterus.
Often occurring in the fallopian tube; resulting in abdominal pain, fainting, and/or vaginal bleeding.
2. Pregnancy with a single fetus.
2. Development of an impregnated ovum in an ovarian follicle.
2. Ectopic pregnancy (development of the fertilized ovum outside of the uterine cavity) with development of the fetus within an ovary.
Often occurring in the fallopian tube with abdominal pain, fainting, and/or vaginal bleeding.
These taxa are united by a number of features, the most important of which is that the fertilized eggs are incubated by the females, and remain stuck to the pleopods (swimming legs) until they are ready to hatch.
Pregnancy in which two or more fetuses exist simultaneously. It may be monovular (resulting from the fertilization of a single ovum) or polyovular (resulting from the fertilization of more than one ovum).
When more than two fetuses coexist, they may come from one ovum or be the result of combined monovular and polyovular twinning.
2. A physiological state in which a woman exhibits symptoms of pregnancy but is not pregnant.
3. A usually psychosomatic condition, occurring in both males and females, in which physical symptoms of pregnancy are manifested without conception; also called false pregnancy, pseudopregnancy.
4. A psychosomatic state that occurs in a woman without conception and is marked by some of the physical symptoms (as cessation of menses, enlargement of the abdomen, and apparent fetal movements) and changes in hormonal balance of pregnancy.
2. An ectopic pregnancy (gestation elsewhere than in the uterus) that involves the development of the embryo within the fallopian tube: "Salpingocyesis can result in a surgical emergency when the developing embryo reaches a critical size."
