Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Ovarian pregnancyGestational age: Gestational age (or menstrual age) is a measure of the age of a pregnancy where the origin is the woman's last normal menstrual period (LMP), or the corresponding age as estimated by other methods. Such methods include adding 14 days to a known duration since fertilization (as is possible in in vitro fertilization), or by obstetric ultrasonography.Pregnancy rate: Pregnancy rate is the success rate for getting pregnant. It is the percentage of all attempts that leads to pregnancy, with attempts generally referring to menstrual cycles where insemination or any artificial equivalent is used, which may be simple artificial insemination (AI) or AI with additional in vitro fertilization.Pregnancy test: A pregnancy test attempts to determine whether a woman is pregnant. Markers that indicate pregnancy are found in urine and blood, and pregnancy tests require sampling one of these substances.Placenta: The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply, fight against internal infection and produce hormones to support pregnancy. The placenta provides oxygen and nutrients to growing babies and removes waste products from the baby's blood.Interstitial pregnancyTeenage Mother (film): Teenage Mother (a.k.Medical abortion: A medical abortion is a type of non-surgical abortion in which abortifacient pharmaceutical drugs are used to induce abortion. An oral preparation for medical abortion is commonly referred to as an abortion pill.Gestational thrombocytopeniaTrophoblast: Trophoblasts (from Greek trephein: to feed, and blastos: germinator) are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta. They are formed during the first stage of pregnancy and are the first cells to differentiate from the fertilized egg.Prenatal diagnosis: Prenatal diagnosis or prenatal screening (note that prenatal diagnosis and prenatal screening refer to two different types of tests) is testing for diseases or conditions in a fetus or embryo before it is born. The aim is to detect birth defects such as neural tube defects, Down syndrome, chromosome abnormalities, genetic disorders and other conditions, such as spina bifida, cleft palate, Tay Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, Muscular dystrophy, and fragile X syndrome.Unintended pregnancy: Unintended pregnancies are pregnancies that are mistimed, unplanned or unwanted at the time of conception. Unintended pregnancy mainly results from engaging in vaginal sexual activity without the use of contraception, or due to incorrect use of a contraceptive method, but may also arise from the failure of the contraception method when used correctly to prevent pregnancy.Transplacental carcinogenesis: Transplacental carcinogenesis is a series of genotypic and/or phenotypic changes in the cells of a fetus due to in utero exposure to carcinogens. Specifically, these changes are identified as malignant by virtue of their metastatic potential.Decidual reaction: The decidual reaction is the changes in the endometrium of the uterus that prepare it for implantation of an embryo. These changes are observed in each menstrual cycle and enhanced after implantation.Birth weight: Birth weight is the body weight of a baby at its birth.Definitions from Georgia Department of Public Health.Uterus transplantation: The uterine transplant is the surgical procedure whereby a healthy uterus is transplanted into a female organism of which the uterus is absent or diseased. As part of normal mammalian sexual reproduction, a diseased or absent uterus does not allow normal embryonic implantation, effectively rendering the female infertile.Biocell Center: Biocell Center is an international company specializing in the cryopreservation and private banking of amniotic fluid stem cells. The company is headquartered in Italy with several international locations and is involved with numerous partnerships and research studies of amniotic fluid stem cells,.Gestational hypertensionAbdominal pregnancyLower segment Caesarean section: A lower (uterine) segment Caesarean section (LSCS) is the most commonly used type of Caesarean section used today. It includes a transverse cut just above the edge of the bladder and results in less blood loss and is easier to repair than other types of Caesarean sections.Natural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures:National Birth Defects Prevention Network: The National Birth Defects Prevention Network (NBDPN) was founded in 1997. It is a 501(c)3 not-for-profit volunteer organization whose members are involved in birth defects surveillance, prevention and research.Embryo transfer: Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary.National Down Syndrome SocietyInternational Association of Plastics DistributorsMisoprostolEquine chorionic gonadotropin: Equine chorionic gonadotropin (eCG) is a gonadotropic hormone produced in the chorion of pregnant mares. Most commonly called pregnant mare's serum gonadotropin (PMSG) in the past, the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination.Nordli's Cabinet: Nordli's Cabinet governed Norway between 15 January 1976 and 4 February 1981. The Labour Party cabinet was led by Odvar Nordli.Low birth-weight paradox: The low birth-weight paradox is an apparently paradoxical observation relating to the birth weights and mortality rate of children born to tobacco smoking mothers. Low birth-weight children born to smoking mothers have a lower infant mortality rate than the low birth weight children of non-smokers.Twin reversed arterial perfusionDiachylon: Diachylon (from Lat diachȳlōn, representing Gr , "[a medicament] composed of juices"),, . also rendered diachylum or diaculum, was originally a kind of medicament made of the juices of several plants (thus its name), but now commonly the name for lead-plaster, emplastrum plumbi—a plaster made of lead oxide boiled together with olive oil and water.Villitis of unknown etiology: Villitis of unknown etiology, abbreviated VUE, is an inflammatory process that involves the chorionic villi (villitis) whose cause (etiology) is not known. VUE is associated with recurrent miscarriage and intrauterine growth restriction, and recurs in subsequent pregnancies.Selective reduction: Selective reduction (or multifetal pregnancy reduction or MFPR) is the practice of reducing the number of fetuses in a multifetal pregnancy, say quadruplets, to a twin or singleton pregnancy.Puerperal disorderEchogenic intracardiac focus: Echogenic intracardiac focus (EIF) is a small bright spot seen in the baby’s heart on an ultrasound exam. This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart.QRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.Sylvia Lawler: Sylvia Dorothy Lawler, born Sylvia Dorothy Corben and later remarried as Sylvia Dorothy Bagshawe (1922–1996), worked in the field of human genetics.Male lactation: Male lactation in zoology means production of milk from mammary glands in the presence of physiological stimuli connected with nursing infants. It is well documented in the Dayak fruit bat.Anembryonic gestationMaternal-fetal medicine: Maternal-fetal medicine (MFM) is the branch of obstetrics that focuses on the medical and surgical management of high-risk pregnancies. Management includes monitoring and treatment including comprehensive ultrasound, chorionic villus sampling, genetic amniocentesis, and fetal surgery or treatment.Unexplained infertility: Unexplained infertility is infertility that is idiopathic in the sense that its cause remains unknown even after an infertility work-up, usually including semen analysis in the man and assessment of ovulation and fallopian tubes in the woman.merckmanuals > Unexplained Infertility Last full review/revision November 2008 by Robert W.
