Аннотация:SUMMARY X‐ray microanalysis of air dried and ultrathin frozen and frozen dried sections of human sperm cells has indicated a large deviation of elemental composition between cells in a single sample and between samples. Analysis of air dried cells indicates a similar subcellular elemental distribution to that found in sectioned material. Sodium to potassium ratios are found to be similar in both preparations. Air drying is considered a valid method for the preparation of sperm cells for analysis.
