...rized by low FSH, LH and testosterone (T) and absent or impaired sexual development at puberty. Amongst others, mutations in GPR54 and GnRH receptor (GNRHR) are possible causes of HH. 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...

... growth hormone (GH) and testosterone (T). GH and T affect linear growth velocity (LGV) directly through stimulation of chondrocytes and osteoblasts. 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...

... increase (P<0.05) in testosterone level. However, level of glucose (mmol/lit) and blood urea nitrogen (mg/lit) and triglycerides (mg/lit) were found significantly lower. Therefore it is concluded from the present study that dietary supplementation of fat to crossbred bulls during hot summer tropical conditions can reduce the influence of heat stress on reproductive performance and thus enhances the semen quality.

After the recovery period, EROD, GST, malondialdehyde, estradiol/testosterone levels were found to be lower than the control. In the pesticide mixture group, the activity ...

Blood samples were collected individually 60 minutes before and 120 minutes after NMS administration at 15 minutes intervals. Plasma T and GH concentrations were determined by using specific Enzyme Immunoassay (EIA) kits. 4...
