PURPOSE Report the characteristics of cryopreserved semen from a cohort of male cancer patients, attitudes towards cryopreservation and outcomes of semen samples based on a 12-year cryopreservation program. MATERIAL AND METHODS Data from 98 male cancer patients whose sperm samples were banked were evaluated. Demographic parameters, semen characteristics,(More)
OBJECTIVE To assess fertilization, pregnancy, and miscarriage rates after intracytoplasmic sperm injection (ICSI) with epididymal or testicular spermatozoa from different types of azoospermia. DESIGN Retrospective study. SETTING Academic medical center and private fertility center. PATIENT(S) Two hundred twelve patients underwent 257 ICSI cycles. (More)
PURPOSE The development of intracytoplasmic sperm injection spawned new methods of sperm retrieval for men with obstructive azoospermia who did not want to undergo reconstruction of the seminal tract. There is a wide array of different procedures that may be performed in these cases, for instance percutaneous epididymal sperm aspiration (PESA) and(More)
PURPOSE We assessed fertilization, pregnancy and miscarriage rates in patients with obstructive and nonobstructive azoospermia who underwent intracytoplasmic sperm injection. MATERIALS AND METHODS From June 1996 to March 2000, 166 consecutive patients (198 intracytoplasmic sperm injection cycles) with azoospermia were studied. Of these 198 cycles 68 were(More)
OBJECTIVE Our aim was to assess the suppression of spermatogenesis and sperm retrieval rate after testicular sperm extraction (TESE) or testicular sperm aspiration (TESA) in adult rats with surgically induced cryptorchidism. METHODS Adult rats were submitted to TESE and TESA procedures after 15 days of induced cryptorchidism. After spermatozoa retrieval,(More)
OBJECTIVES To evaluate the outcomes of repeated testicular sperm aspirations (TESAs) and to investigate whether the interval between TESA procedures, success in the first attempt, and patient age might influence the results. METHODS The patient population in the present study consisted of couples undergoing TESA for intracytoplasmic sperm injection. Of(More)
