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.
