HCG

HCG is made by the cells of the placenta during pregnancy. The placenta gives fertilized eggs nourishment after attachment to the uterine wall. HCG levels double every 72 hours, peaking during pregnancy weeks eight to 11 and leveling off for the rest of the pregnancy, according to the American Pregnancy Association.

Testing

Levels of hCG are detectible by blood test approximately 11 days after conception, according to the American Pregnancy Association. A home pregnancy test can detect hCG in the urine 12 to 14 days after conception.

Infertility

An injection of hCG is sometimes used as an infertility treatment to cause ovulation. A false positive pregnancy test may occur if the test is performed fewer than 10 days after hCG is injected, according to the American Society for Reproductive Medicine.

HGH

HGH is a hormone produced by the pituitary gland at the base of the brain. HGH helps children grow and supports organs and tissues throughout the lifespan. The production of HGH decreases in middle age.

Athletes

A synthetic form of HGH can be used by athletes as a performance-enhancing drug. HGH is banned by the International Olympic Committee and the National Collegiate Athletic Association.

Weight loss

The use of hCG and HGH as weight loss treatments is controversial. The Journal of the American Medical Association and the Food and Drug Administration warn of the dangers of using hCG as a weight loss aid. In the June 18, 2008 issue of the "Journal of the American Medical Association," Dr. S. Jay Olshansky and Dr. Thomas T. Perls state that, "Systematic reviews have found that HGH supplementation does not significantly increase muscle strength or aerobic exercise capacity in healthy individuals."
