Testicular sperm extraction in azoospermic men submitted to bilateral orchidopexy.
BACKGROUND This study was carried out to evaluate whether bilateral orchidopexy represents a poor or good prognostic factor in azoospermic men undergoing testicular sperm extraction (TESE). METHODS One hundred and seven presumed non-obstructive azoospermia (NOA) patients, according to conventional clinical parameters (volume of testis, FSH, clinical history) were submitted to testicular biops...

متن کاملTesticular sperm extraction in azoospermic patients with gonadal germ cell tumors prior to chemotherapy--a new therapy option.
BACKGROUND In view of the high cure rates in patients with testicular germ cell tumors (TGCT), increasing clinical importance is attached to protection of fertility. Long-term infertility due to cytostatic therapy may be expected in more than 50% of the patients at a cumulative dose of cisplatin > 0.6 g/m2. The standard procedure for fertility protection in cancer patients includes cryopreserva...
متن کاملFactors influencing sperm retrieval following testicular sperm extraction in nonobstructive azoospermia patients
OBJECTIVE Azoospermia owing to testicular disorders is the most severe manifestation of male infertility. The main concern for patients with nonobstructive azoospermia (NOA) is the probability of successful sperm retrieval following testicular sperm extraction (TESE). Therefore, the goal of this study was to determine predictive factors correlated with sperm retrieval. METHODS We assessed the...
متن کاملIncreased Fertilization Rates after In Vitro Culture of Frozen-Thawed Testicular Immotile Sperm in Nonobstructive Azoospermic Patients
Objective. To optimise the use of freeze/thaw testicular immotile spermatozoa from nonobstructive azoospermia patients and to analyse the outcome of intracytoplasmic sperm injection (ICSI) of such spermatozoa. Methods. Testicular specimens were retrieved and cryopreserved from forty patients with nonobstructive azoospermia and underwent one cycle with thawed spermatozoa (Group I) that led to pr...
