Is the hormone HCG with the sole purpose present during pregnancy?
Answers:
Only in pregnancy and a few random tumors of the endometrium, ovaries and testes. Source(s): http://emedicine.medscape.com/article/43…
Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced surrounded by pregnancy that is made by the developing 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 to say critical for a pregnancy in humans. hCG may have additional functions; for instance, it is thought that hCG affects the immune tolerance of the pregnancy. Early pregnancy trialling, in general, is based on the detection or breadth of hCG. Because hCG is produced also by some kinds of tumor, hCG is an important tumor marker, but it is not certain whether this production is a contributing cause or an effect of tumorigenesis.
β Subunit of human chorionic gonadotropin (β-hCG), measured by immunoassay, is the major clinical marker contained by women with gestational trophoblastic neoplasia (GTN)—a disease spectrum that includes hydatidiform mole, nonmetastatic GTN, and metastatic GTN and in about 2/3 of men near testicular embryonal carcinoma or choriocarcinoma. The β subunit is measured because it is specific for hCG. Source(s): http://en.wikipedia.org/wiki/Human_chori…

Serum HCG concentrations in non-pregnant women increase with the age of the women.Between 41 and 55 years of age an HCG between 5.0 and 14.0 IU/L is quite typical and with a normal FSH does not indicate pregnancy. Source(s): GP for more years than I care to remember
yep :)
