A study of meiotic preparation of human spermatocytes and their relationship to infertility.

Although our experience is based on a small series of 50 cases we believe that several points can be made. Meiotic preparations can be performed in any competent cytogenetic laboratory. These preparations appear to yield more specific information as to the site of arrest and may be more reliable than the static testicular biopsy to appraise the true status of spermatogenesis. With these facts in mind a more accurate prognosis and therapeutic regimen can be realized.
