Meiotic figures in the testicular biopsy of subfertile males.
The phases and sequence of meiotic division are herein reviewed and illustrated as they occur in the human testis. Normally all phases of meiosis can be identified, and arrest at a phase is indicative of faulty spermatogenesis. The correlation of these arrest patterns with the clinical course and response to clinical therapy is now in progress. These meiotic studies can be undertaken in any laboratory with cytogenetic capabilities, and this study is intended to serve as a base line illustration of the normal.
Biopsy↗
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.
