It is formed in the body at a relatively constant rate. It is apparently derived from the metabolism of the high-energy phosphate compound, phosphocreatine. Creatine is found abundantly in muscle and is composed of amino acids: glycine, arginine and methionine. Creatinine is solely derived from creatine. Serum creatinine values rise in renal failure. It is present in maximum amount in the striated muscle. Smaller amounts are found in the smooth muscle, testes, liver and kidney. Creatinine is a waste material. This creatinine is readily excreted in the urine. Creatinine excretion increases during pregnancy. </span></em></p>

The creatinine was found to be highest during September when the male was approaching maturity. Similarly the mean ranges from creatinine in the female were noted to be 0.7 &ndash; 1.10 mg%. The higher values were noted during January (mid-pregnancy). </span></em><em><span style=\"font-size: 10.0pt; line-height: 150%; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: Calibri;\" lang=\"EN-US\">The objective of this present study is to investigate the relationship between the reproductive status of the male and female and the Serum Creatinine values throughout the reproductive cycle. </span></em></p>
