ROS and Male fertility ... 4
Posted in 2013
ROS formation and redox signaling play a role in physiology and in a variety of pathologies, including inflammatory, infectious, and degenerative disorders, either in humans or in animals. ROS are involved in a variety of pathophysiological conditions of the testis, and oxidative stress is known to inhibit ovarian and testicular steroidogenesis. The disruption of redox signaling and control and imbalance in favor of prooxidant species define oxidative stress [
Oxidative stress is a state in which an oxidant-generating system overcomes an antioxidant defense system, a process that is involved in many diseases including male factor infertility and/or subfertility. ROS are products of normal cellular metabolism and are formed during the normal enzymatic reactions of intercellular and intracellular signaling . ROS overproduction can be induced through physiological or pathological mechanisms, including ROS generation by leukocytes as a cytotoxic mechanism of host defense, during hypoxic states leading to high levels of ROS, as well as by drugs with oxidizing effects on cells. Then, when mitochondria become a target of elevated levels of ROS, the process of oxidative phosphorylation might be affected because of a possible damage of proteins and membrane lipids. Lipids are present in the sperm plasma membrane in the form of polyunsaturated fatty acids (PUFAs) that contain more than two carbon-carbon double bonds. ROS attacks PUFA in the cell membrane, leading to a cascade of chemical reactions called lipid peroxidation.
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 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, ge...
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 secret...
World Health day...Beat Diabetes Brought to U.... http://successgain.us and http://successgain.info My memories World Health day...Beat Diabetes Posted in 2016 World Health Day 2016: 6th April 2016 is World Health Day...World Health Organization focused on Diabetes this year because the statistical data of Diabetes is increasing rapidly... 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 modif...
