  Human chorionic gonadotropin - Wikipedia, the free encyclopedia
Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception and later by the trophoblast (part of the placenta).
hCG is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa.
The ability to quantitate the βhCG level is useful in the evaluation of ectopic pregnancy and in monitoring germ cell and trophoblastic tumors.

 Human Chorionic Gonadotropin/Robert Maragoul
Human chorionic gonadotropin (hCG) is a glycoprotein hormone that was originally identified by virtue of its involvement in reproduction.
The synthesis of hCG starts declining between the 11th and 12th week of gestation and is maintained at a low level throughout the pregnancy, besides the intact hormone, free hCG subunits, enzymatically modified molecules are found in the urine and also in the serum of pregnant women.
Human chorionic gonadotropin (hCG) which is a pregnancy hormone is a heterodimeric glycoprotein gormone that is involved in activation of the adenylate-cyclase system in luteal cells, which is essential for the maintenance of the corpus luteum in early pregnancy.

HCG, a hormone produced during pregnancy, is detectable in the blood or urine 1 to 2 days after implantation of the fertilized egg in the uterus (10 days after ovulation).
HCG also stimulates the development of fetal gonads and synthesis of androgens (male hormones) by the fetal testes.

HCG is clinically used to make women ovulate, or to invoke birth in pregnant women.
In these cases too HCG can have a use, but most of the time testicular atrophy will not have progressed to such a stage that it is an absolute necessity.
HCG IS and always will be an important part of post-cycle recovery, but it should never be run too long or at too high a dose and should always be accompanied by the use of either Clomid or Nolvadex.

Objectives: The objective of this review was to assess the effects of human chorionic gonadotrophin administration during early pregnancy on the risk of miscarriage in women with a history of recurrent miscarriage.
Human chorionic gonadotrophin was associated with a reduced risk of miscarriage for women with a history of recurrent miscarriage (odds ratio 0.26, 95% confidence interval 0.14 to 0.52).
Authors' conclusions: There is not enough evidence to evaluate the use of human chorionic gonadotrophin during pregnancy in order to prevent miscarriage in women with a history of unexplained recurrent spontaneous miscarriage.

 Hormones: Does High HCG Always Mean Pregnancy?
I was told my HCG level is high (over 5) and that this shows I am pregnant.
Rarely, after menopause the pituitary gland production of hCG increases to the point where it may be detectable; this is usually associated with a high level of the hormone LH as well.
If the HCG level is rising, you may be pregnant, or there may be a tumor.

Abstract: Although urine has been used widely for the qualitative detection of human chorionic gonadotrophin (hCG), serum is chosen conventionally for the serial quantification of the hormone to monitor trophoblastic activity.
Human chorionic gonadotrophin (hCG) is a glycoprotein hormone comprising two dissimilar subunits, termed ot and P. It is produced by trophoblastic tissue during pregnancy and in trophoblastic disease.
The hormone is present in both serum and urine in a range of molecular forms, including intact hCG, nicked hCG molecules, free subunits, and Beta-core fragments.' Early pregnancy is characterised by the sequential appearance of hCG and 0-hCG.

A hydatidiform mole is one of the gestational trophoblastic diseases which arises from the fetal chorion with varying degrees of trophoblastic proliferation, produces human chorionic gonadotrophin, and, in malignant cases, responds well to chemotherapy.
The diagnosis is made by assessing serum concentrations of human chorionic gonadotrophin, ultrasound scanning, and by histological examination of curettings after evacuation of products of conception.
Serial serum concentrations of human chorionic gonadotrophin should be checked at regular intervals, to monitor the rate and consistency of decline.
