HYPERSPERMIA - THE FORGOTTEN CONDITION

The seminal volumes of 4223 men with known periods of abstinence of ej aculation, complete collections and with no dysfunction known to affec t production of accessary gland secretions have been examined to defin e a minimum value for hyperspermia. The 95th percentile of the skewed data distribution was 6.3 ml and of the 229 men with values equal to o r greater than this, 113 (49.3%) had sperm concentrations below the Wo rld Health Organization accepted minimum 'normal' value of 20 x 10(6)/ ml. Basic seminal parameters should not be forgotten when assessing in fertile men.
