Boar sperm are susceptible to oxidative damage caused by reactive oxygen species (ROS) during storage. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) is an important therapeutic target, because it a cellular metabolism energy sensor and key signalling in spermatozoa. We evaluated the effects of rosmarinic acid (RA), antioxidant, on boar liquid storage determine whether protects via AMPK activation. ejaculates were diluted with Modena extender different concentrations RA stored at 17°C for 9 days. Sperm quality parameters, antioxidant capacity, metabolism, phosphorylation fertility analysed. Compared control, 40 μmol/L significantly improved motility, plasma membrane integrity acrosome (p < .05).

Numerous factors trigger male infertility, including lifestyle, the environment, health, medical resources and pathogenic microorganism infections. Bacterial infections of reproductive system can cause various diseases. Several organs, such as testicles, have unique immune functions that protect germ cells from damage. In system, recognize pathogen-associated molecular patterns carried by microorganisms activate host’s innate response. Furthermore, bacterial lead to oxidative stress through multiple signaling pathways. Many studies revealed serves dual functions: moderate help clear invaders maintain sperm motility, but excessive will induce host Additionally, is always accompanied autophagy which also homeostasis. Male homeostasis disequilibrium inflammation genitourinary influence spermatogenesis, even infertility. Here, we focus on effect infection in explore crosslink between during this process.

Physiologically, autophagy is an evolutionarily conserved and self-degradative process in cells. Autophagy carries out normal physiological roles throughout mammalian life. Accumulating evidence shows as a mechanism for cellular growth, development, differentiation, survival, homeostasis. In male reproductive systems, spermatogenesis steroidogenesis need balance between degradation energy supply to preserve metabolic The main of includes the formation maturation phagophore, autophagosome, autolysosome. controlled by group autophagy-related genes that form core machinery autophagy. Three types mechanisms have been discovered cells: macroautophagy, microautophagy, chaperone-mediated classified non-selective or selective. Non-selective macroautophagy randomly engulfs cytoplasmic components autophagosomes are degraded lysosomal enzymes. While selective precisely identifies degrades specific element, current findings shown novel functional reproduction. It has recognized dysfunction can be associated with infertility.

Drosophila is a powerful model to study how lipids affect spermatogenesis. Yet, the contribution of neutral lipids, major lipid group which resides in organelles called droplets (LD), sperm development largely unknown. Emerging evidence suggests LD are present testis and that loss lipid- LD-associated genes causes subfertility; however, key regulators remain unclear. Here, we show early-stage somatic germline cells within testis. We identified role for triglyceride lipase brummer ( bmm ) regulating LD, found whole-body leads defects development. Importantly, these represent cell-autonomous roles Because lipidomic analysis mutants revealed excess accumulation, spermatogenic were rescued by genetically blocking synthesis, our data suggest -mediated regulation influences This identifies as an important contributes development, reveals levels during

Obesity is a significant global health and socio-economic challenge, considered an important risk factor for poor outcomes including male reproductive dysfunction infertility. As excess adiposity causes testicular infertility, novel therapeutic strategies require investigation. Nigella sativa (Ns) seed oil metformin have both demonstrated potential positive effect on obesity, although remain poorly investigated in fertility. Therefore, this study aimed to determine the of Ns total body weight (TBW), mitochondrial membrane (MMP), serum testosterone semen parameters obese animal model. Wistar rats (n = 54) were divided into six groups: normal chow (NC), high sugar diet (HSD) only, HSD saline, (75 mg/Kg/day), (200 mg/Kg/day) (NS200), (400 (NS400).

Semen samples collected from ten Ross broiler breeders (52-wk) using abdominal massage, then divided into 4 equal aliquots and cryopreserved Beltsville extender that contained different concentrations (0 µM, 0.01µM, 0.1µM, 1µM) RSV. higher percentage (P < 0.05) total motility membrane integrity observed RSV-0.1 compared other frozen groups. Moreover, sperm mitochondrial activity RSV-0.01 control 0.05). lowest apoptotic like changes found comparison groups RSV-1 levels H2O2 O2− groups, respectively. Malondialdehyde (MDA) concentration, velocity average path (VAP), linearity (LIN) not affected by RSV > We dose-dependent increase exposed Thus, increased phosphorylation but had no positive on post thaw parameters. Our findings suggest improve thawed functions, these might be mediated through activation kinase.
