Aim: To determine whether sulfasalazine can prevent apoptosis in spermatogenic cells by preventing the activation of NF-kappaB in spermatogenic epithelium in experimental testicular torsion.
Methods: Thirty-two adult male Sprague-Dawley rats were subjected to unilateral 720 degree testicular torsion for durations of 0 h and 2 h, then the torsion was relieved. The ischemic/reperfused testes were collected for the detection of NF-kappaB expression with Western blotting and immunohistochemistry techniques, and detection of apoptosis with TUNEL techniques.
Results: The NF-kappaB coefficient of spermatogenic epithelium and the apoptosis index of spermatogenic cells were significantly different in the operation and the sham-operation groups after experimental testicular torsion (P<0.01).
Conclusion: NF-kappaB activation of spermatogenic epithelium is related to apoptosis of spermatogenic cells. Sulfasalazine can prevent apoptosis in spermatogenic cells after the experimental testicular torsion through prevention of NF-kappaB activation.

Cisplatin (CIS) is a widely used chemotherapeutic agent, but its side effects, such as oxidative stress, inflammation, and apoptosis, often lead to male reproductive damage. Oxidative stress, primarily caused by the excessive generation of reactive oxygen species (ROS), plays a critical role in disrupting testicular homeostasis, resulting in spermatogenic impairment and tissue injury. L-cysteine (CYS), a semi-essential amino acid with potent antioxidant and anti-inflammatory properties, may offer protection against CIS-induced oxidative damage.

Aim: Nowadays, the electromagnetic field (EMF) has become an issue of electromagnetic pollution. This study aimed to determine the effect of 5 G Fr1 frequency band EMF waves on endoplasmic reticulum (ER) stress in testicular tissue and to demonstrate the efficacy of coenzyme Q10 (CoQ10) in suppressing the potential situation.
Materials And Methods: Three groups of eight male Sprague-Dawley rats were established.

Diquat (DQ) is a pro-oxidant that generates free radicals in cells through redox reactions, leading to the induction of oxidative stress. During the processes of growth and reproduction, poultry are particularly vulnerable to oxidative stress. Selenium yeast (SeY) serves as an organic selenium source characterized by high activity and low toxicity, imparting antioxidant effects.

Background: The establishment of kinetochore-microtubule attachment is essential for error-free chromosome alignment and segregation during cell division. Defects in chromosome alignment result in chromosome instability, birth defects, and infertility. Kinesin-7 CENP-E mediates kinetochore-microtubule capture, chromosome alignment, and spindle assembly checkpoint in somatic cells, however, mechanisms of CENP-E in germ cells remain poorly understood.
