The Australian scientist has found out, that the daily ejaculation within a week raises quality of a semen, improving, thus, ability of the man to conception of the child.

In research of accoucheur-endocrinologist David Grininga (David Greening) from company Sydney IVF with the raised level of defective DNA 118 men have taken part in spermatozoons. This level made from 15 to 98 percent (on the average 34 percent).
It was offered to participants of experiment ejaculate daily within a week, thus not accepting any medicines and not changing a way of life. After that their semen has been sent on the repeated analysis.

The average level of defective DNA in analyses has decreased to 26 percent.

Thus at 80 percent of volunteers appreciable improvement of quality of a semen while at the others it has worsened was observed. Experiment also has shown, that, despite some depression of volume of a semen allocated at an ejaculation, mobility of spermatozoons in it has raised, that raises probability of conception.

Gring has assumed, that quality of a semen at regular sexual activity raises that DNA of spermatozoons, is long testicles being in seed canaliculuses, is more strongly treated to damaging action of free radicals.
On the basis of results of research the scientist has recommended to the pairs, wishing to conceive the child, to have sex daily within a week before an ovulation.

The obtained data confirm results of the research spent in 2003 in Israel. Then scientists have proved, that long abstention worsens characteristics of spermatozoons.
