This study aimed at identification of mutations in GPR54 and GNRHR genes and their correlation with HH in Pakistani boys. Thirty one boys with delayed puberty and thirty one normal age matched controls were examined. Genomic DNA was extracted and amplified by PCR using specific p...

Furthermore, T promotes LGV through augmentation of GH secretion. Nevertheless, age and developmental stage dependent changes in GH and T and LGV and their associations require further investigation. This study examined relationships between GH and LGV, T and LGV and GH and T in 540 normal healthy boys of 1 to 20...

In this study, although the application of different castration methods in 4-month-old male Norduz sheep resulted in changes in the blood hormone levels, it was determined that these changes did not affect body weight. In conclusion, the evaluation of the process in castrated six-mo...
