ROS and Male fertility ... 7
Posted in 2013

During the final phase of the ejaculation, only high numbers of ROS-producing leukocytes are harmful to sperm functions. An infection which involves ROS in the epididymis, prostate gland, and/or seminal vesicles could indirectly damage sperm functions.
In 1943, a paper was published showing the effect of high oxygen tensions on motility and prevention of this phenomenon by adding catalase, which suggested the involvement of oxygen overload in motility of spermatozoa . Indeed, ROS generation was dependent on the oxygen tension; higher oxygen tensions increased ROS generation, mainly from leukocytes, whereas low oxygen tensions improved the survival rate and penetration capacity.
Oxidative stress has been considered a main cause to male infertility, but studies have showed that low and verified concentrations of ROS play a pivotal role in sperm physiological processes such as capacitation, hyperactivation, acrosome reactions, and signaling processes to provide a suitable fertilization, but an increase in oxidative stress leads to male infertility by the induction of peroxidative damage to the sperm plasma membrane, DNA damage, and apoptosis. ROS must be maintained at appropriate levels to ensure appropriate physiological function while preventing pathological damage to the spermatozoa. ROS is thought to influence fertility by affecting sperm membranes and sperm DNA. They reduce sperm motility and its ability to fuse with the oocyte and compromise paternal genomic contribution to the embryo; in fact, sperm are vulnerable to oxidative stress-induced damage due to the high portion of PUFA and also due to the low concentrations of scavenging enzymes in their cytoplasm, both contributing to the defective sperm function observed in a high percentage of infertility.

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

Possible Male fertility Problems

Possible Male Fertility problems  My memories Possible Male Fertility Problems Posted in 2015  Sexually Transmitted diseases or other infections.  G enital infections such as chlamydia  and gonorrhea  can cause infertility in men. The infertility can often be resolved by treating the infection. Blockages, birth defects   , or physical damage . In  some cases, men are born with blockages in parts of the testicle or other abnormalities that prevent sperm from getting into the semen. Physical trauma to the testicles, prostate, and urethra can also result in fertility problems. Surgery can sometimes correct the problem. Retrograde ejaculation.  In  this disorder, semen doesn't come out of the penis  during ejaculation, but instead enters the bladder. It can be caused by diabetes , certain medications , and surgery to the bladder, prostate, or urethra. Genetic diseases .  Although it's rare, genetic illnesses such as cystic fibrosis  or chromosomal disorders can c

At present,  type 1 diabetes  cannot be prevented. The environmental triggers that are thought to generate the process that results in the destruction of the body’s insulin-producing cells are still under investigation. While there are a number of factors that influence the development of  type 2 diabetes , it is evident that the most influential are lifestyle behaviours commonly associated with urbanization. These include consumption of unhealthy foods and inactive lifestyles with sedentary behaviour. Studies from different parts of the world have established that  lifestyle modification  with  physical activity  and/or  healthy

Reproduction of Human Beings - Male

Reproduction of Human Beings - Male Brought to U.... http://successgain.us     and    http://successgain.info My memories Reproduction of Human Beings- Male Posted in 2013 Reproduction in human beings is by sexual reproduction where both the male and female gametes fertilize to give rise to an embryo. The fertilization of human embryo occurs inside the body of the female. Thus, it is called Internal Fertilization. Human Beings are viviparous organisms who give rise to Embryos directly instead of laying eggs. Let us understand a little more about the male and female reproductive organs and the process of fertilization in them. Male Reproductive System Testes:  Male humans have two testes. They are situated in a bag of skin known as the scrotum. Scrotum lies outside the pelvic cavity. Sperm Duct:  These are thin ducts that arise from the testes. Prostrate Gland:  This gland is an accessory gland in males which pours its secretions into the sperm duct along with the
