a hormone secreted by the placenta during pregnancy that prolongs the life of the corpus luteum, progesterone production and the preserves the pregnancy. This hormone accounts for pregnancy tests being positive. It may also be administered therapeutically in some infertility problems or in males for the treatment of cryptorchidism.
A hormone of early pregnancy that can be monitored to determine the age and viability of the gestation. This hormone is also used as an injection in ovarian stimulation regimens to cause the final maturation of the oocyte (egg) and its follicle and eventually cause ovulation.
a substance produced by the placenta that maintains the corpus luteum causing it to produce progesterone during pregnancy
A commercially available, semi-purified hormone that is used to induce ovulation and spermiation, i.e., egg and sperm production.
A hormone, produced by the implanting embryo (and subsequently also by the placenta), whose presence in the woman's blood indicates a possible pregnancy; hCG may also be administered to women undergoing stimulation with hMG alone or in combination with other fertility drugs in order to trigger ovulation. Injections of hCG may also be administered to encourage the production of progesterone by the corpus luteum in the hope of promoting implantation following embryo transfer and thereby reducing the incidence of spontaneous miscarriage in a pregnancy resulting from IVF. The hormone hCG is derived from the urine of pregnant women.
A hormone produced by the placenta of a pregnant woman indicative of pregnancy.detected in most pregnancy tests.
The hormone produced by the placenta. hCG levels normally double every other day in early pregnancy. Slowly rising hCG levels indicative of an impending miscarriage or an ectopic pregnancy. Purified hCG is injected to trigger ovulation or egg maturation during ovulation induction and IVF cycles respectively.
Endocrine Marker - HCG is a hormone normally secreted in greatest quantities during the first trimester of pregnancy by placental syncytiotrophoblastic cells. Antibodies, directed against the beta sub-unit of this hormone, identify cells of trophoblastic origin in germ cell tumors of the testis, ovary, mediastinum, and other sites.
(HUE-men kor-ee-AH-nik go-NA-duh-tro-pin) Human hormone produced by the placenta during pregnancy. HCG is also a tumor-associated antigen present in various types of cancer, including gynecological, colorectal, testicular, bladder, liver, stomach, pancreatic, lung, brain and kidney cancers.
A hormone secreted by the placenta that preserves the pregnancy by prolonging the life of the corpus luteum and stimulating progesterone production. A pregnancy test is positive when hCG is detected. It can be administered therapeutically (Pregnyl or Profasi) to help solve some infertility problems.
A hormone produced by the placenta important for keeping the mother's body from rejecting the fetus as a foreign tissue
A hormone produced by the placenta of a pregnant woman; it is what is detected in most pregnancy tests.
A gonadotropin secreted by the human placenta.
Hormone produced by the placenta that can stimulate ovulation.
female hormone that stimulates ovulation (often injected as a fertility drug).
hormone produced early in pregnancy by the placenta; detection in the urine and serum is the basis for one kind of pregnancy test
A hormone that increases early in pregnancy. It is produced by the cells of the placenta that attach the baby to the uterus. Its detection is the basis of all pregnancy tests. It is also used as a drug given to the woman to time ovulation. Once this drug, is given the woman predictably ovulates in 36-40 hours.
A hormone that is produced by the body in the early stages of pregnancy. It enables the corpus luteum to continue producing Progesterone. In assisted conception HCG is used 36 hours prior to egg retrieval to mature the eggs ready for the egg collection procedure.
A hormone that increases early in pregnancy. This hormone is produced by the placental tissue. Its detection is the basis of pregnancy tests. It can also be used as an LH substitute to trigger ovulation in conjunction with clomiphene or gonadotropin therapy. The U.S. trade names are A.P.L.â, Pregnylâ, and Profasâ.
A hormone produced by the placenta during a pregnancy. Measurement of this hormone is the basis of pregnancy tests. An unusually high level of this hormone in the second trimester is one reason that further testing for Down syndrome may be recommended. An unusually low level may indicate a rare chromosome abnormality called trisomy 18.
A hormone produced by the placenta: It is the hormone of pregnancy and its detection is used in pregnancy tests.
hormone produced by the placenta during early pregnancy.
a hormone produced by the placenta about 10 days after fertilization.
A hormone produced by the embryo and thought to be related to nausea in early pregnancy
A hormone made by chorionic cells (in the fetal part of the placenta). It is a very similar hormone to LH but it has a longer time of action
The hormone produced early in pregnancy to keep the corpus luteum in the ovary producing progesterone; may be injected to stimulate ovulation and progesterone production. Its detection is the basis for the pregnancy test.
A peptide hormone secreted by the chorion that prolongs the life of the corpus luteum and prevents the breakdown of the uterine lining.
a hormone secreted by the placenta that maintains pregnancy during the early development of the embryo. HCG is made up of 2 subunits, alpha and beta; the beta subunit (bHCG) has been shown to suppress the development of Kaposi's sarcoma cells in vitro.
This hormone is produced during early pregnancy andkeeps the corpus luteum producing progesterone. hCG is also used to triggerovulation during fertility treatments.
Human Chorionic Gonadotropin is a hormone released into the maternal bloodstream by the developing placenta from about six days after the last period was due (about 22 days after the last menstrual period). Its presence can be detected in the urine by a home pregancy test and a positive result indicates pregnancy. Gonadotropins are used to treat infertility, hypogonadism and nonobstructive cryptorchidism. Abbreviated to HCG.
A hormone produced by the placenta during pregnancy; its detection is the basis for most pregnancy tests. Also used during ovulation induction to trigger ovulation.
A hormone produced by the placenta during pregnancy that triggers the release of estrogen and progesterone. Excreted in urine, hCG is used in testing to detect pregnancy.
A hormone produced following ovulation, it aids the corpus luteum in production of progesterone, required to prepare the uterine lining for implantation of the fertilized egg.
(hCG) A human hormone made by chorionic cells in the fetal part of the placenta . Human chorionic gonadotropin (hCG) is directed at the gonads and stimulates them. Hence, the name "gonadotropin." See the entire definition of Human chorionic gonadotropin
A hormone that can be used to trigger ovulation. Sold under the names Novarel, Pregnyl, and Ovidrel.
A hormone that helps the ovaries produce progesterone and estrogen during the first trimester of pregnancy.
A hormone secreted by the placenta during pregnancy that prolongs the life of the corpus luteum, stimulates progesterone production and thus preserves the pregnancy. This hormone accounts for a pregnancy test being positive. It may also be administered therapeutically (PREGNYL/PROFASI) for some infertility problems.
The hormone produced by the placenta. This is the hormone pregnancy tests look for.
The placental hormone that maintains the corpus luteum for the first 3 months of pregnancy.
a hormone secreted by the placenta. Home pregnancy kits test for this hormone.
A hormone produced by the placenta whose function is identical to that of LH. This hormone is used to prepare the follicle to release the egg and its timing of administration is critical to the egg retrieval procedure. The retrieval is timed to occur only hours before the eggs actually get released from the follicles. It is also the hormone measured in a pregnancy test.
The hormone hCG is the hormone that is produced by the early pregnancy and is what is measured in pregnancy tests. This hormone is similar in appearance to the gonadotropin LH so is used to trigger ovulation.
The hormone that prolongs the lifespan of the corpus luteum as well as stimulates production of progesterone, another hormone essential to maintain the pregnancy. This is also the hormone that pregnancy tests (blood and urine) detect.
The hormone produced in early pregnancy which keeps the corpus luteum producing progesterone. Also used via injection (Profasi) to trigger ovulation after some fertility treatments, and used in men to stimulate testosterone production.
Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception and later by the syncytiotrophoblast (part of the placenta). Its role is to prevent the disintegration of the corpus luteum of the ovary and thereby maintain progesterone production that is critical for a pregnancy in humans. hCG may have additional functions, for instance it is thought that it affects the immune tolerance of the pregnancy. Early pregnancy testing generally is based on the detection or measurement of hCG.
