At the same time, a question arises: How can a physician make sure that the β-hCG is of an endogenous source and not the residue of the prescribed drugs (hCG)? In this article we have studied the elimination time of 1M injection of 5000 IU hCG in 11 normal, and 1M injection of 5000 and 10,000 IU hCG in 11 Rokitansky patients. The time of complete elimination of β-hCG from the circulation in 10 normal women and 5 Rokitansky patients receiving 5000 IU of hCG were 7-11, and 7-8 days respectively. There was no statistically significant difference between these two groups. Comparing the two groups of Rokitansky patients receiving 5,000 and 10,000 IV of hCG, the elimination time were dose-dependent, and were significantly different from each other (P }, URL = {http://mjiri.iums.ac.ir/article-1-1561-en.html}, eprint = {http://mjiri.iums.ac.ir/article-1-1561-en.pdf}, journal = {Medical Journal of the Islamic Republic Of Iran}, doi = {}, year = {1990} }
