Apoptosis and Oxidative stress
Posted in 2013


Oxidative stress is implicated between causes of male infertility. ROS production and its effects on semen quality have been widely clarified. Oxygen is essential to sustain life, and physiological levels of ROS are necessary to maintain normal cell functions. However, products of oxygen such as ROS can be detrimental to cell function and survival .
ROS are detrimental to sperm survival and function due to its adverse effects on sperm membrane and genetic material. High frequency of single- and double-stranded DNA breaks due to oxidative stress activates apoptosis by inducing cytochrome c and caspases 9 and 3. Disruption of inner and outer mitochondrial membranes results in release of cytochrome c, a protein which activates caspases and induces apoptosis. Mitochondrial exposure to ROS results in the release of apoptosis-inducing factor, which directly interacts with the DNA and leads to DNA fragmentation . Seminal oxidative stress, sperm DNA damage, and apoptosis constitute a unified pathogenic molecular mechanism in infertility. Therefore, apoptosis in semen could be a useful indicator of semen quality.



My advise
1...  Oxygen is important for our life.   Without oxygen we cannot survive
2...  Oxygen is important for digesting our food
3...  Oxygen is important for our brain, lungs and kidney function,, cleaning our blood etc..
4...  Oxygen is important for sperm health of the male
5...  Follow healthy food for your body and sperm health
