Fetal nutrition during pregnancy.

1. Ectopic pregnancy, ectopic pregnancy: the development of a fertilized ovum outside the uterus, as in a fallopian tube.
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.

Normal uterine pregnancy.

1. Superfetation or the formation of a fetus as the result of an impregnation occurring after another impregnation but before the birth of the offspring produced by it.
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.

1. A pregnancy resulting from gestation elsewhere than in the uterus: ectopic pregnancy, extrauterine pregnancy, ectopic gestation, extrauterine gestation.
2. A gestation elsewhere than in the uterus.

Often occurring in the fallopian tube; resulting in abdominal pain, fainting, and/or vaginal bleeding.

1. Pregnancy with one fetus as opposed to twins, etc.
2. Pregnancy with a single fetus.

1. Extrauterine pregnancy in an ovary.
2. Development of an impregnated ovum in an ovarian follicle.

1. Ovarian pregnancy or the 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.

Ectopic pregnancy; a gestation elsewhere than in the uterus.

Often occurring in the fallopian tube with abdominal pain, fainting, and/or vaginal bleeding.

A sub-order of decapod crustaceans.

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.

Multiple pregnancies or bearing two or more fetuses simultaneously.

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.

1. A false impression of pregnancy.
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.

1. Pregnancy in a uterine tube.
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."
