The Australian scientist revealed that ejaculating everyday within a week period increases the quality of the sperm and thus improves the ability of the man to conceive a baby. The research held by obstetrician-gynaecologist David Greening from Sydney IVF Company was aimed at 118 men experiencing increased defective DNA sperm level.

This level varied from 15 to 98% (34% averagely). The participants of the experiment were offered to ejaculate everyday throughout the week without taking any drug and changing their lifestyle somehow. After this their sperm was forwarded for the recurring test.

The average level of the defective DNA decreased to 26%.

Furthermore according to the data 80% of the volunteers experienced considerable improvements of the sperm quality and the others however have their sperm quality worsened. The experiment has also showed that despite certain decrease of the volume of the sperm ejaculated the mobility of the sperm cells increased thus really increasing the possibility of the conception.
Greening has supposed that the sperm quality in regular sexual activity increases due to the fact that the DNA of sperm cells staying in the testicular tubules is more exposed to damaging effect of the free radicals.

Basing on the results of the research the scientist advised those married couples wishing to conceive a baby to have an everyday sex within a week before the ovulation.

The data obtained confirm the research being held in 2003, Israel. The scientists have confirmed that long continence decreases the sperm cells characteristics.
