...ole in the regulation of spermatogenesis acting primarily at the hypothalamic level of the gonadotropic axis. Citric acid is synthesized and secreted by the prostate gland. Its synthesis is regulated by androgens. As, dose dependent degeneration of prostate gland has been described following intraperitoneal kisspeptin treatment. However, effects of kisspeptin administration on the levels of prostatic citric acid remain elusive till date. The present study, the...

In this study, online software and luciferase reporter gene system were used to predict and verify the target relationship between miR-122 and DUSP4/PDK4, miR-449a and FKBP1B. Thereafter, comparison analysis was done on miR-122, miR-449a, DUSP4, PDK4 and FKBP1B mRNA expression levels in different bull testes tissues (1-day, 12-months-old and 24-months-old). In addition, genes m...

Such changes may be responsible for delayed refractory phase.The intact stages of spermatogenesis indicates that the thiram-e...

PFOS ≥ 11 mg/kg (accumulative dosage) resulted in visible histopathological changing in testis, including disorder and vacuolization of spermatogenic cells. Changed testicular organ coefficient (for dosage ≥ 55 mg/kg), decreased sperm concentration (for 110 mg/kg dosage), decreased motility (for 110 mg/kg dosage) and increased sperm malformation (for all of the treated groups) were also confirmed (p...

Gonads attain maximum size and weight in spawning phase during summer. Free oozing of spermatozoa in testes and ovaries packed with fully grown eggs are the distinct features of this phase. The highest values of Gonadosomatic Index (GSI) for male and female in summer coincided with the histological structure of the gonads w...
