Abstaining from sex before fertility treatment doesn't help men become more potent, says a new study.

The findings were presented recently at the annual meeting of the European Society for Human Reproduction and Embryology in Madrid, Spain.

The new research by Israeli fertility experts challenges the current medical opinion that it's beneficial for men to refrain from sex for two to seven days before undergoing some forms of fertility treatment.

Six thousand men went without
The scientists tested more than 7200 semen samples for semen volume, sperm concentration and shape, and the percentage and total amount of active and moving (motile) sperm. The samples were collected from about 6000 men who had abstained from sex for up to two weeks.

More than 4500 of the samples had normal sperm counts. The remainder had varying count levels, from mild to severe.

Volume up, quality down
While the volume of semen increased up to 11 to 14 days of abstinence, the shape and form of the sperm gradually deteriorated, whatever the sperm count.

In the samples taken from men with reduced sperm counts, the proportion of motile sperm fell significantly from the second day onward of abstinence, reaching a low at the sixth day and remaining low, the study found. - (HealthDayNews)
