Endometrium: The endometrium is the inner mucous membrane of the mammalian uterus.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.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.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.Trophoblast: 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.Immunosurgery: Immunosurgery is a method of removing an external cell layer of an object. Immunosurgery is to expose the specimen to a solution containing antibodies against the object, remove that solution and subsequently expose the object to complement.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.Natural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures:False pregnancyUnexplained 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.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.Stromal cell: Stromal cells are connective tissue cells of any organ, for example in the uterine mucosa (endometrium), prostate, bone marrow, and the ovary. They are cells that support the function of the parenchymal cells of that organ.Reproductive technology: Reproductive technology (RT) encompasses all current and anticipated uses of technology in human and animal reproduction, including assisted reproductive technology, contraception and others.Interstitial pregnancyOvarian tissue cryopreservation: Ovarian tissue cryopreservation is cryopreservation of tissue of the ovary of a female.Mature messenger RNA: Mature messenger RNA, often abbreviated as mature mRNA is a eukaryotic RNA transcript that has been spliced and processed and is ready for translation in the course of protein synthesis. Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, it consists exclusively of exons, with all introns removed.Endosalpingiosis: In gynecology, endosalpingiosis is a condition in which fallopian tube-like epithelium is found outside of the fallopian tube. It is unknown what causes this condition.Low Fertility Cohorts Study: The Low Fertility Cohorts Study, 1978: A Survey of White, Ever-Married Women Belonging to the 1901-1910 United States Birth Cohorts,Data Sharing For Demographic Research consists of personal interviews of white, ever-married women born between July 1, 1900, and June 30, 1910. In 1978, a national survey of 1,049 married women between the ages of 68 and 78 were interviewed between the months of March and July in order to investigate low fertility during the 1920s and 1930s and the women of childbearing age during those decades.Equine 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.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingEstradiol cypionate: Estradiol cypionate (INN, USAN) (brand names Depo-Estradiol, Depofemin, Estradep, and many others), or estradiol cipionate, is a synthetic ester, specifically the 3-cyclopentylpropanoyl ester, of the natural estrogen, estradiol. It was first introduced in 1952 by Upjohn in the United States, and has been in widespread use since.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.Oocyte selection: Oocyte selection is a procedure that is performed prior to in vitro fertilization, in order to use oocytes with maximal chances of resulting in pregnancy. In contrast, embryo selection takes place after fertilization.Fallopian tube obstructionLipoxinSquamous epithelial cell: In anatomy, squamous epithelium (squama- + -ous) is that whose outermost (apical) layer consists of thin, flat cells called squamous epithelial cells. The epithelium may be composed of one layer of these cells, in which case it is referred to as simple squamous epithelium, or it may possess multiple layers, referred to then as stratified squamous epithelium.Pacemaker syndrome: Pacemaker syndrome is a disease that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation.Gonadotropin-releasing hormone analogue: A gonadotropin-releasing hormone analogue (GnRH analogue or analog), also known as a luteinizing hormone releasing hormone agonist (LHRH agonist) or LHRH analogue is a synthetic peptide drug modeled after the human hypothalamic gonadotropin-releasing hormone (GnRH). A GnRH analogue is designed to interact with the GnRH receptor and modify the release of pituitary gonadotropins FSH and LH for therapeutic purposes.Multi-link suspension: __NOTOC__Down syndrome cell adhesion molecule like 1: Down syndrome cell adhesion molecule like 1 is a protein in humans that is encoded by the DSCAML1 gene.Estrous cycle: The estrous cycle (also oestrous cycle; derived from Latin oestrus and originally from Greek οἶστρος meaning sexual desire) comprises the recurring physiologic changes that are induced by reproductive hormones in most mammalian therian females. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases or pregnancies.Gestational 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.Cell adhesionMaternal to zygotic transition: Maternal to zygotic transition (MZT) is the stage in embryonic development during which development comes under the exclusive control of the zygotic genome. This requires both zygotic genome activation (ZGA) and degradation of maternal products.Coles PhillipsProgesterone receptor: The progesterone receptor (PR, also known as NR3C3 or nuclear receptor subfamily 3, group C, member 3), is a protein found inside cells. It is activated by the steroid hormone progesterone.Stratified squamous epithelium: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.Corpus luteum cystMatrix model: == Mathematics and physics ==Spermiogenesis: Spermiogenesis is the final stage of spermatogenesis, which sees the maturation of spermatids into mature, motile spermatozoa. The spermatid is more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria.Afterload: Afterload is the pressure in the wall of the left ventricle during ejection. In other words, it is the end load against which the heart contracts to eject blood.Symmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Congenital estrogen deficiency: Congenital estrogen deficiency is a genetic condition by which the body is unable to produce or use estrogens.ScaarMorphant: An organism which has been treated with a morpholino antisense oligo to temporarily knock down expression of a targeted gene is called a morphant.Multicenter Automatic Defibrillator Implantation Trial: Multicenter Automatic Defibrillator Implantation Trial and MADIT II are implantable cardioverter defibrillator (or ICD) trials which investigate whether prophylactic ICD therapy in moderately high-risk coronary patients (in addition to conventional therapy) would significantly reduce death compared with patients treated with conventional therapy alone.Intraocular lens power calculation: The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the surgeon determines the IOL power.
