MeSH

The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.

Year introduced: 1963

A type of pregnancy in which the EMBRYO IMPLANTATION occurs in the horn of the UTERUS instead of in the uterine cavity, i.e. at the junction of the uterus and one of the FALLOPIAN TUBES.

Year introduced: 2015

A type of pregnancy in which EMBRYO IMPLANTATION occurs in an OVARY instead of in the uterine cavity.

Year introduced: 2015

A rare type of abnormal pregnancy in which EMBRYO IMPLANTATION occurs at a lateral angle of the UTERUS, medial to the uterotubal junction and the ROUND LIGAMENT OF UTERUS.

Year introduced: 2015

A type of ectopic pregnancy in which the extrauterine EMBRYO IMPLANTATION occurs in the portion of the FALLOPIAN TUBE that traverses the muscular wall of the uterus.

Year introduced: 2015

MULTIPLE PREGNANCY with EMBRYO IMPLANTATION occuring at different locations, involving both an intrauterine site and an extrauterine (ECTOPIC PREGNANCY) site.

Year introduced: 2013

Time interval, or number of non-contraceptive menstrual cycles that it takes for a couple to conceive.

Year introduced: 2013

The condition of carrying QUINTUPLETS simultaneously.

Year introduced: 2012

The condition of carrying QUADRUPLETS simultaneously.

Year introduced: 2012

The condition of carrying TRIPLETS simultaneously.

Year introduced: 2012

The condition of carrying TWINS simultaneously.

Year introduced: 2012

Unintended or accidental pregnancy, including pregnancy resulting from failed contraceptive measures.

Year introduced: 2005

A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.

Year introduced: 2005

Large (>160 kDa) glycoproteins with electrophoretic mobility of ALPHA-GLOBULINS, found in high concentration in the plasma of pregnant women but also in a number of species including mouse, rat, and others (ALPHA-MACROGLOBULINS). In humans, they are always present in the circulation and are nonspecific inhibitors of PROTEINASES, similar to COMPLEMENT PROTEINS (C3; C4; C5).

Year introduced: 2018 (2004)

The ratio of the number of conceptions (CONCEPTION) including LIVE BIRTH; STILLBIRTH; and fetal losses, to the mean number of females of reproductive age in a population during a set time period.

Year introduced: 1996

Selective abortion of one or more embryos or fetuses in a multiple gestation pregnancy. The usual goal is to improve the outcome for the remaining embryos or fetuses.

Year introduced: 1995

Pregnancy in which the mother and/or FETUS are at greater than normal risk of MORBIDITY or MORTALITY. Causes include inadequate PRENATAL CARE, previous obstetrical history (ABORTION, SPONTANEOUS), pre-existing maternal disease, pregnancy-induced disease (GESTATIONAL HYPERTENSION), and MULTIPLE PREGNANCY, as well as advanced maternal age above 35.

Year introduced: 1995

The co-occurrence of pregnancy and parasitic diseases. The parasitic infection may precede or follow FERTILIZATION.

Year introduced: 1993

Pregnancy, usually accidental, that is not desired by the parent or parents.

Year introduced: 1991(1973)

The most common (>96%) type of ectopic pregnancy in which the extrauterine EMBRYO IMPLANTATION occurs in the FALLOPIAN TUBE, usually in the ampullary region where FERTILIZATION takes place.
