There were investigated women suffering from tubo-peritoneal form of infertility at the age ranged 20–40 years. It resulted in establishment of a direct dependence of the adhesion process degree on the activity of N-acetyltransferase. A high activity of the enzyme was mostly revealed in women with IV degree of the adhesion process and second infertility. The average and low activity of N-acethyltransferase was found in women with I degree of the adhesion process and primary infertility. In most cases the average and low activity of N-acetyltransferase was revealed in women of the 1st and the 2nd age group. It is proved that determination of the activity of N-acetyltransferase may be used as an express-diagnostic method and prediction of the possibility of the adhesion process development and its degree in women with primary and secondary infertility.
