Daily Sex "Helps Improve Sperm Quality"Australian study - Having sex daily increase sperm quality and thus assist men who have fertility problems.
The study was conducted on 118 Australians whose semen showed alterations, the researchers found that daily ejaculation for a week increased significantly reduce the number of DNA damage sperm of patients.
Dr David Greening and colleagues at the private clinic Sydney IVF (Australia), specializes in fertility problems, participants were asked to have sex every day for a week. After seven days, doctors have observed in 81% of subjects a decrease of 12% of the amount of damaged sperm. Sperm quality can also be improved if men do not smoke, do not abuse alcohol, do exercise and ingest more antioxidants.
Although the sperm count has dropped to 180 million per ml to 70 million per ml, men were still in the "range of fertility."
Since he led the study, Dr Greening said now recommend to all couples seeking advice to improve their fertility to begin to love more. One suggestion that seems to contradict the older men but delight the youngest, said the doctor.
Sex frequent help to improve sperm quality by preventing it from staying too long in the body. The sperm DNA was indeed more likely to be damaged when staying long in the body. Also heat can also make sperm less mobile.
Some experts welcomed the study but added that it does not prove that sex daily allows men with fertility problems to have a better chance of producing babies. Dr Greening and colleagues are still analyzing the results of the study to determine how many companions of participants became pregnant.
If confirmed, the discovery could have implications for in vitro fertilization (IVF) as was previously recommended for couples to abstain for two days just to increase sperm count.
"Studying the DNA of sperm is only part of the puzzle" said his side Bill Ledger, professor of obstetrics and gynecology at the University of Sheffield, Great Britain, who has not participated in the study.
"This may improve pregnancy rates, but we still need to study further" Mr. Ledger also believes that apply to couples with fertility problems to have greater love could harm their relationship.
"This could add to the anxiety and do more harm than good." Couples should not feel obliged to change their sexual life to have a baby, he said.

Sperm counts are falling at an alarming rate - up to 38 per cent in a decade - with diet and lifestyle largely to blame.
A Spanish study has found that even in young men, sperm concentration fell by an average of two per cent a year - and could soon hit levels where fertility is compromised.
A ten year-study of more than 200 men found the average concentration went from 72 million spermatozoids per millilitre in 2001 to 52 million/ml in 2011.
The Spanish study found that even in young men, sperm concentration fell by an average of 2 per cent a year
The researchers, from the University of Murcia. say the findings are important because previous research has shown that a concentration lower than 40 million/ml makes conception more difficult.
'If the rate of loss we have outlines continues, with an average decline in quality of two per cent per year, the sperm of young men could reach this danger level of 40 million/ml in a very short space of time,' said co-researcher Professor Jaime Mendiola.
In the study, researchers at the University of Murcia compared the results of 273 men aged between 18 and 23 years from the nearby town of Almeria, collected between 2001 and 2002.
They compared these with samples collected ten years later by 215 undergraduates from Murcia, all the while ensuring that both
sample groups had the same age range and similar characteristics.
sample groups had the same age range and similar characteristics.
The researchers found that men living in Murcia had a significantly lower sperm count compared to those living in Almeria.
Furthermore, 40 per cent of the university students in Murcia had an alteration to one parameter of their sperm, e.g. the mobility or morphology.
Lead researcher Alberto Torres Cantero, professor of Preventative Medicine and Public Health at the university, said the study was also significant because it was the first study to evaluate the evolution of sperm quality in young Spanish men over ten years.

'Before, there were no well performed studies to detect a change in sperm quality in Spain,' he said.
But he added the fact that semen quality has worsened does not necessarily mean that the number of infertile men has increased.
He said: 'This study measures semen quality and not fertility, for which specific criteria established by the World Health Organisation are used.'
'We believe that some prevention actions involving lifestyle improvements, such as a healthier diet, could increase sperm quality,' he added.
For this reason, the authors stress the urgency for more research to highlight lifestyle interventions that could stem the decline in sperm quality.
The research is published in the journal Andrology.
Only last month a major French study found that sperm counts and quality have fallen sharply since the start of the 1990s.
It is believed the trend is linked to diet, lifestyle and ‘gender bender’ chemicals - and possibly even tight underwear.
Between 1989 and 2005, average sperm counts fell by a third in the study of 26,000 men, increasing their risk of infertility. The amount of healthy sperm was also reduced, by a similar proportion.
The study is important because, with over 26,600 men involved, it is probably the largest studied sample in the world.

The findings also confirm research over the past 20 years that has shown sperm counts declining in many countries across the world.
The fact that the decline was progressive over the 17-year period indicates the problem is ongoing, the researchers said.
A leading British expert said it was inevitable that falling sperm counts would affect male fertility and action was needed to investigate the causes
