Scientists believe that after the age of semen quality is deteriorating rapidly
All the representatives of the stronger sex older "tridtsatnika" urgently need to attend to the problem of procreation! Staff at the Shanghai Institute of Family Planning, analyzing data thousands of volunteers aged 20-60 years installed: after 30 years, the quality of sperm is reduced each year by 1%.
Exploring the state of reproductive function of men, the experts paid attention to the most important indicators of semen: total volume of semen, sperm count and motility.
They compared the samples of the seed of representatives of different age groups and found that after 35 years, many men sperm proved to be inactive. This is despite the fact that the subjects were male normal life, do not abuse alcohol and smoking.
And the quality of the sperm is also decreased with increasing age of the volunteers. For example, in the seed of 20-29-year-old 73% of the sperm were motile, but for 50-60 years, this figure is barely 65%.
The results obtained by Chinese doctors, confirm previous studies of the Israeli Center for Assisted Reproduction Eylau. The local doctors examined the success rate of fertility in men of all ages. And so, at 30-35-year-old macho fertilization success rates are on average 13, 6% of men the same age 45 years - no more than 9, 3%, said NEWSru Israel.
Reproduction is also the Israeli claim that in recent years the quality of sperm in men in general has fallen sharply. Researchers compared samples of seminal fluid collected in 1995-1999, and the samples were obtained from 2004 to 2008. It turned out, for this time the sperm concentration dropped by 40%. And Israeli sperm banks have to reject two or three potential donors due to low sperm quality.

Semen analysis: whether the good fellow - will become a father!
Women to learn about the possibility of normal to have a baby, you need to pass a lot of surveys. Men, in order to ensure that he can be a father, you need a single, but very informative analysis - semen, says urologist, andrologist Eugene Chebotarev. From this research it is possible to learn a lot of interesting things:
The amount of sperm (at a "blowout") is less than 2 ml deemed insufficient in terms of nutrients and immunoactive substances. But do not tear your hair out! The farm will fit all: if other parameters are normal, so the sperm can be successfully used for artificial insemination.
Liquefaction time (norm - 10-40 min.) shows the energy content of active substances, which are necessary for sperm motility and reaching the egg. If this time is less than 10 minutes, the yield - also artificial insemination.
Acidity (Ph) - OK 7 2 - 7, 8. The change it indicates that infertility may be inflammations in the urogenital system. We need to find them and cure.
Number of spermatozoa per 1 ml - The norm rather blurred - between 40 and 500 million. By the way, when there are more, too, no sugar: all the pushing, rushing herd and interfere with each other to get close to the egg.
Abnormal sperm. The rate - up to 50%, because every family has its black sheep. But if there are more, there is the probability of a child with disabilities. Reasons: bad habits, radiation, occupational diseases (for example, work with toxic substances).
Agglutination of sperm. This is a terrible word means only "bonding." It so happens that all the sperm seems to be healthy and active, but do not rush to the goal of orderly and intertwined tails, huddling together. As a result, the goal of any one. This happens in chronic inflammations and autoimmune diseases (rheumatoid arthritis, lupus erythematosus).
White blood cells semen indicate the presence of inflammation in the testis or prostate.
IMPORTANT!
This analysis is necessary to seriously prepare. Even a temporary stay monk. To be honest at least 3 days prior to the study did not drink alcohol (even beer!), The same refrain from sexual intercourse, do not eat smoked and spicy. If you decide to cheat themselves will experience: sensitivity studies, the results of fault of their own can get worse than expected. Then the analysis will have to do again.
