Postchemotherapy ejaculatory azoospermia: fatherhood with sperm from testis tissue with intracytoplasmic sperm injection.

PURPOSE: To define the success of testis sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) in azoospermic men with a history of chemotherapy. PATIENTS AND METHODS: In a retrospective study, 23 men with ejaculatory azoospermia and a history of chemotherapy underwent TESE in a search for usable spermatozoa. In six patients cryopreserved tissue and in nine patients fresh tissue provided sperm for an ICSI cycle. Histologic analysis of the testis was performed in all patients. The presence or absence of sperm, fertilization rates with ICSI, and final outcomes of pregnancy were recorded. RESULTS: Spermatozoa were found on TESE in 15 (65.2%) of 23 men. On histopathology, the predominant pattern observed was Sertoli cell only (47.8%), followed by hypospermatogenesis (30.4%), mixed (17.4%), and late maturation arrest (4.3%). The fertilization rate was 65.2%, and ongoing/delivered pregnancies occurred in 30.8% of cycles. Six healthy boys and four healthy girls have been born to date. CONCLUSION: Men who are azoospermic and have had prior cytotoxic therapy make up a small subgroup of males with nonobstructive azoospermia. It is important to define and characterize this subgroup and better define their true fertility potential. Approximately two thirds of these men have retrievable testis sperm, which may be used with ICSI to have healthy offspring. This exciting avenue for paternity has heretofore not been available to such patients.

Testicular tissue extraction in a young male with 47,XXY Klinefelter's syndrome: potential strategy for preservation of fertility.

OBJECTIVE: To describe a case involving the cryopreservation of testis tissue retrieved from a 15-year-old male teenager with Klinefelter's syndrome. DESIGN: Case report. SETTING: An academic medical center. PATIENT(S): A 15-year-old boy with Klinefelter's syndrome. INTERVENTION(S): Microsurgical testis sperm extraction with cryopreservation of harvested tissue. MAIN OUTCOME MEASURE(S): Spermatozoa within testis tissue. RESULT(S): Successful extraction and cryopreservation of three vials of sperm-containing testis tissue. No effect on subsequent testosterone levels. CONCLUSION(S): Testis tissue extraction in the adequately virilized but azoospermic young male with 47, XXY Klinefelter's syndrome may be a strategy to preserve future biological paternity.

Intra-abdominal pulmonary sequestration: a benign suprarenal mass.

A 34-year-old white woman presented with an 8.5-cm left suprarenal mass. Evaluation revealed normal adrenal hormone function. Pathologic examination after surgical removal revealed a rare benign condition, intra-abdominal extralobar pulmonary sequestration (accessory lung).
