title: Reduced prostaglandin levels in the semen of men with very high sperm concentrations.
abstract: The prostaglandin levels have been measured in a group of men with sperm concentrations greater than 300 X 10(6)/ml and compared with the levels in men with sperm concentrations of 50 to 150 X 10(6)/ml. The distribution of the PG levels in all groups was highly skewed but the data could be transformed to a normal distribution by taking logarithms. Comparison of the PG levels showed a highly significant lowering of the PG levels in the polyzoospermic group when compared wieth either of the groups with normal sperm concentrations.
