Sex differences and gonadal hormone influences are well known for diverse aspects of forebrain amine and indolamine neurotransmitter systems, the cognitive and affective functions they govern and their malfunction in mental illness. This study explored whether hormone regulation/dysregulation of these systems could be related to gonadal steroid effects on(More)
Spontaneous germ cell death by apoptosis occurs during normal spermatogenesis in mammals and is thought to play a role in the physiological mechanism limiting the clonal expansion of such cell population in the male gonad. In the prepubertal rat testis, the most conspicuous dying cells are pachytene spermatocytes, which are also the primary target of the(More)
5-Lipoxygenase (5-LOX), along with 12-lipoxygenase and cyclooxygenases, metabolizes arachidonic acid into eicosanoids. In rodents, 12-lipoxygenase deficiency alters behavioral responses to cocaine. We used 5-LOX-deficient mice and their controls to investigate cocaine's actions. After repeated cocaine injections, the increase in locomotor activity was(More)
BACKGROUND Clusterin, a heterodimeric glycoprotein found at several sites in the human male reproductive tract, could be a marker of morphologically abnormal spermatozoa, while TUNEL positivity indicates DNA fragmentation. Metabolic disorders such as diabetes mellitus and obesity may compromise sperm quality and fertility of men; however, little evidence(More)
