…gastrointestinal cancers; and alpha-fetoprotein and chorionic gonadotropin, which can indicate testicular cancer. The diagnostic tests that are necessary to identify genetic alterations and tumor markers and thereby predict the efficacy of a drug are sometimes referred to as companion diagnostics.

Human chorionic gonadotropin can help evoke maturation of the external genitals, and, in many cases of testes located in the inguinal canal, the testes move into the scrotum subsequent to this drug therapy. If medication fails, surgical treatment is used to move the undescended testis…

…placenta secretes two gonadotropins called human chorionic gonadotropin (HCG) and human placental lactogen (HPL). HCG, like the pituitary gonadotropins, is a glycoprotein, with a molecular weight of 25,000 to 30,000. HPL is a protein, with a molecular weight variously estimated at about 19,000 or 30,000. One or perhaps both of…

Human chorionic gonadotropin (HCG), a hormone produced by cells of the placenta, can be extracted from the urine of pregnant women days after fertilization and thus is used in the early detection of pregnancy. It is also used to stimulate descent of the testicles in…

…on a detectable increase in human chorionic gonadotropin (HCG) in the blood serum and urine during early pregnancy. HCG is the principal hormone produced by the chorionic layers of the placenta, the temporary organ that provides nourishment for the developing fetus. Levels of HCG increase significantly

…elimination of its wastes) of chorionic gonadotropin, an ovary-stimulating hormone. In practice, the tests have an accuracy of about 95 percent, although false-negative tests may run as high as 20 percent in a series of cases. False-negative reports are frequently obtained during late pregnancy when the secretion of chorionic gonadotropin…
