We have obtained a clinical pregnancy in a 26 year old patient by means of in vitro oocyte fertilization by intracytoplasmic injection of spermatozoa obtained from a cryopreserved testicular biopsy. In a first attempt performed with fresh biopsy material, the woman became pregnant, but the pregnancy ended in a spontaneous abortion. In a second cycle, the spermatozoa were retrieved from a cryopreserved sample saved from the first attempt. Twelve metaphase II oocytes were collected and injected; from these, nine became fertilized, three preembryos were transferred at the eighth-cell stage and the other six were cryopreserved. An ongoing clinical pregnancy was obtained with two gestational sacs.
