Illinois, the ability of males to fertilize their partner is determined by the quality of sperm. Many nutrients that can improve sperm quality, one of which is a marine fish that was mentioned most good for the formation of sperm tough.
A study at the University of Illinois shows, content Docosa Hexaenoic Acid (DHA) in marine fish greatly affect the process of sperm formation. If the sperm produced are genetically less good, these nutrients can improve it.
In the process of formation of sperm cells, DHA is required to make a sheath that will accommodate certain enzymes. The better the veil, the more enzymes are conceived by sperm so that its ability to penetrate an egg cell also increased.
"The cells of normal sperm has an arc-like structure called the acrosome, which is very critical role in the process of egg fertilization," said Prof. Manabu Nakamura, who led the study as quoted from Indiavision, Wednesday (11/01/2012).
The role of DHA in the formation of sperm quality proven in an experiment on mice. Some male mice genetically modified to be sterile can finally mendapai inseminate female mice after a high DHA diet for some time.
By adding a fluorescent compound so that sperm can fluoresce, or light, the scientists also proved that changes in the level of fertility in male rats was influenced by the enzyme. Sheath formation of DHA increased the levels of enzymes so that sperm getting tough.
In addition to nutritional factors influenced the quality of sperm is also determined by one's physical and hormonal conditions in general. These conditions must be maintained with a healthy lifestyle, including regular exercise and always try to avoid stress.
Jakarta, sperm quality is affected by many things, from food eaten, physical activity undertaken, to environmental influences. Researchers found that exposure to ozone in the atmosphere also affect the process of sperm development in men.
A study of men who live in Los Angeles found that exposure to ozone can reduce sperm quality. The study, published in the journal Environmental Health Perspectives this could add to the understanding of the causes of infertility in men.
This study analyzed the semen samples collected from a sperm bank in Los Angeles and compare it with the air quality.
The researchers found that exposure to high ozone levels near the homes of donors adversely affect semen quality. The impact of pollutants were found capable of affecting the entire development cycle of sperm in the body (spermatogenesis).
"We found an inverse relationship between ozone exposure and sperm concentration at all points studied. Our data show that sperm are vulnerable to toxic exposure in the entire period of spermatogenesis," said the researcher, Rebecca Z. Sokol as reported Altpenis, Friday (01/13/2012).
This study also analyzed other pollutants such as nitrogen dioxide, carbon monoxide and other fine particles. Each of these air pollutants is believed to affect sperm production, but no affect sperm density.
What causes the ozone mempu reduce sperm production remains unclear. Exposure to ozone is known to cause oxidative stress is known to interfere with testicular function and sperm.
Exposure to ozone can cause an inflammatory reaction, both in the male genital tract or form toxic chemicals that circulate in the body. Both could be expected to cause a decrease in sperm concentration.
"Many of the findings that demonstrate the potential hazards of the environment on the reproductive system. Some of them reported a decline in sperm counts in certain industrialized countries. The validity of these findings is still reaping the controversy. But most researchers agree that the decline in semen quality may be associated with the location geographically, "said Sokol.
Jakarta, sleep disturbances at night often makes the body weak and does not fit the next day which can interfere with daily activities. Many things that cause sleep disorders and several types of foods can also cause sleep disturbances.
Even so every person can have different causes, then it is necessary to know the causes of sleep disturbance and then try to avoid it.
But there's no harm in also to review the types of foods and beverages that have been consumed before bed if you're having trouble sleeping
Here are five foods and beverages that can cause sleep disturbances as quoted from Caring, Thursday (12/01/2012), among others:
1. Cured meats
Should avoid foods that contain meat that is preserved as an afternoon snack. Ham, bacon, sausages and smoked meats contain high levels of the amino acid tyramine.
Amino acid tyramine can trigger the brain to release norepinephrine. Norepinephrine is a brain stimulant that makes people feel alert and awake.
2. Chocolate
Enjoy a drink or snack of chocolate hot chocolate at night is very tempting. However, many people are increasingly sensitive to caffeine because of increasing age.
Sometimes just a small brown sepotongan on ice cream can cause a person to experience sleep disturbances. Chocolate also contains tyrosine, an amino acid stimulus.
Tyrosine is a nonessential amino acid that the body is made from another amino acid called phenylalanine. This is a building block for several important brain chemicals called neurotransmitters, including epinephrine, norepinephrine, and dopamine.
Helps nerve cells communicate and neurotransmitters affecting mood.
3. Energy drinks
Various types of high-caffeine energy drinks typically well as the amino acid taurine. Amino acids taurine and caffeine increase alertness and adrenaline.
The new study results show that, even if you consume energy drinks in the morning, combine high-dose taurine and caffeine can make it difficult to sleep, or sleep with a good quality at a later date.
4. Tomato sauce, chili, pizza, and spicy foods
Indigestion is a common source of sleep disturbance, and many people fail to go back to sleep. Sour and spicy foods can cause reflux, heartburn, indigestion and other symptoms that interfere with sleep.
5. Drinking alcohol
Alcoholic beverages can make feel more relaxed after dinner. But a few hours later, it can prevent to get a good night's sleep. Alcohol can also cause dehydration, so it can make people wake up when sleeping because he wanted to urinate.
How long sperm life when exposed to free air and how long age when there is sperm in the vagina?

Answer
Spermatozoa can survive for 5 days in a woman's body at the level of acidity of the fluid that surrounds the sperm or (pH) of 7.2 to 8, which means belonging to the base instead of acid. Clearly, the semen is to protect the spermatozoa from the acidity of the vagina.
Whereas if the sperm is exposed to free air then in a flash would be destroyed. (Bullock N, Turner W & Cuckow, 2008).

Jakarta, many women who crave big breasts. But the large breasts is not always profitable, because there are still advantages and disadvantages. What?
Woman's breasts are very complex structures. In addition consists of fat and connective tissue, breast milk also contains channels, blood vessels, lymph nodes and the structure known as the lobes and lobules.
Each breast has 12 to 20 parts of lobules (milk-producing glands at the end of the lobe) and duct (milk ducts). Toward the nipple, each duct widens to form a sac (ampulla).
Here are some advantages and disadvantages for women with large breasts as reported Menshealth, Thursday (14/12/2011), namely:
Profit
1. Women with large breasts generally have a more attractive appearanceWhen the breast size according to body size, then the appearance of women could look more attractive. Not just for women, most men regarded women with large breasts more attractive.
2. Increase self-confidenceWith an attractive appearance, can automatically increase the confidence of women. High confidence that allows women to mingle and socialize, so keep him away from depression.
Loss
1. Large breasts are less sensitiveIn a study conducted at the University of Vienna in Austria found that 24 percent of the breast is less sensitive than small-sized breasts.
"It's because of the small breasts of the nerve that transmits the sensation of the nipple is more stretched," said Alan Matarasso, MD, a plastic surgeon in New York City.
In addition, large breasts have more glandular tissue than fat tissue (the most sensitive part of the breast), thus causing large breasts more or less sensitive.
2. More difficult to detect breast cancer lumps"In the Realize (breast self-examination, for the detection of breast cancer), it is easier to detect breast lump in the back when its small size, because the layer through which a little more," said Dr. Marisa Weiss, oncologist and founder of breastcancer.org.
3. More frequent back pain and neckBig breasted women usually have poor posture because of the pressure at the front of the body is too big.
"Breasts are bigger and heavier certainly puts pressure on the body. This changed the posture of a woman so that her neck tense and are more likely to experience headaches and back," says Dr. Weiss.
