Production
Like other gonadotropins, hCG can be extracted from urine or by genetic modification. Pregnyl, Follutein, Profasi, Choragon and Novarel use the former method, derived from the urine of pregnant women. Ovidrel, on the other hand, is a product of recombinant DNA. hCG is produced from the syncytiotrophoblast cell layer.

Famous quotes containing the word production:
“The production of too many useful things results in too many useless people.”
—Karl Marx (1818–1883)
“The growing of food and the growing of children are both vital to the family’s survival.... Who would dare make the judgment that holding your youngest baby on your lap is less important than weeding a few more yards in the maize field? Yet this is the judgment our society makes constantly. Production of autos, canned soup, advertising copy is important. Housework—cleaning, feeding, and caring—is unimportant.”
—Debbie Taylor (20th century)
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
