background: there are many studies focused on long or short storage time of epididymal sperm (eps) of different species. there are limited studies on preservation or cryopreservation of the domestic goat eps. objective: the aim of the present study was to evaluate the effects of ex vivo cold-storage on freezing of eps from goat (capra hircus). materials and methods: in a split-plot design the c...

Epididymal sperm aspiration and in-vitro fertilization (IVF) with intracytoplasmic sperm injection is an established treatment for obstructive azoospermia. Sperm aspiration is performed with either an incision or percutaneously. To control costs, minimize morbidity and retain the advantages of both approaches, we developed a mini-incision technique for epididymal aspiration and here report sper...

A variety of surgical options exists for sperm retrieval in the setting of obstructive azoospermia (OA). With appropriate preparation, the majority of these techniques can safely be performed in the office with local anesthesia and with or without monitored anesthesia care (MAC). The available techniques include percutaneous options such as percutaneous epididymal sperm aspiration (PESA) and te...

Surgical sperm retrieval through percutaneous epididymal aspiration was used to manage effectively unexpected obstructive azoospermia on the day of oocyte retrieval.

BACKGROUND Factors influencing success of sperm retrieval in azoospermic patients and outcome of ICSI were evaluated. METHODS AND RESULTS Uni- and multifactorial analysis were performed using logistic and stepwise analysis, following surgical sperm retrieval by percutaneous epididymal sperm aspiration (55 cycles) or testicular sperm extraction (142 cycles) in 52 and 123 patients with obstruct...

OBJECTIVES Male infertility caused by irreparable obstructive azoospermia is widely treated with MESA (Microsurgical Epididymal Sperm Aspiration) or TESE (Testicular Sperm Extraction) or PESA (Percutaneous Epididymal Sperm Aspiration) followed by an Intracytoplasmatic Spermatozoa Injection (ICSI). For each procedures are claimed advantages and disadvantages. Aim of this work is to describe our ...

USING EPIDIDYMAL AND TESTICULAR SPERM FROM AZOOSPERMIC MEN: THE CLEVELAND CLINIC EXPERIENCE Mehmet Oder, Ramadan A Saleh, Namita Kattal, Mohamed A Bedaiwy, Anthony J Thomas, Ashok Agarwal, Cleveland Clinic Foundation Objective: Sperm retrieval from testis and epididymis, combined with ICSI, has significantly enhanced the chances of azoospermic men to father their own genetic offspring. The impa...

The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percutaneous sperm aspiration to open excis...

OBJECTIVE To evaluate cost per delivery using two different initial approaches to the treatment of postvasectomy infertility. DESIGN Model of expected costs and results in the United States in 1994. SETTING Men with postvasectomy infertility, evaluated and treated at centers with experience in vasectomy reversal or sperm retrieval and ICSI. PATIENT(S) Men with postvasectomy infertility, w...
