The clinical management of men with nonobstructive azoospermia (NOA) seeking fertility has been a challenge for andrologists, urologists, and reproductive medicine specialists alike. This review presents a personal perspective on the clinical management of NOA, including the lessons learned over 15 years dealing with this male infertility condition. A five-consecutive-step algorithm is proposed...

Male infertility may occur due to obstructive and non-obstructive reasons, some pathologies be corrected with surgical medical treatment. Such treatment increase the possibility of spontaneous pregnancy, success assisted reproductive technology, also testicular sperm retrieval rate. This review will focus on alternatives in infertile males. Although options for varicocele men include open surgi...

OBJECTIVE In sever oligospermia; one of the paths used for surgical sperm retrieval (SSR) is to extract sperm via a testicular biopsy. The aim of our study is to determine the reliable time interval between testicular biopsy and intracytoplasmic sperm injection (ICSI) procedure in order to obtain optimumsperm parameters (count, motility and normal morphology). MATERIALS AND METHODS This cohor...

The use of non-ejaculated sperm coupled with intracytoplasmic sperm injection has become a globally established procedure for couples with azoospermic male partners who wish to have biological offspring. Surgical methods have been developed to retrieve spermatozoa from the epididymides and the testes of such patients. This article reviews the methods currently available for sperm acquisition in...

Abstract Study question TESE is widely used for obstructive azoospermia (OA) as a surgical method sperm retrieval, but it benefiting the patient? Summary answer Since MESA-ICSI has very good fertilization rate, clinical pregnancy rate and delivery MESA should be employed OA subjects, not TESE. What known already micro-TESE are technically simple, retrieval surgery because they do require micros...

background: pentoxifylline (px) prevents camp breakdown by inhibiting the activity of the camp-phosphatase and presumably, stimulates sperm motion. incubation with px causes hyperactivation of sperm, an important step in achieving fertilization, and leads to changes in membranes associated with sperm capacitation. objective: the purpose of this study was to examine the effects of pentoxifylline...

Introduction Cryptozoospermia is defined by the World Health Organization (WHO) as presence of isolated sperm cell in ejaculate only identified after an extended microscopic search or being pelleted. Although number spermatozoa usually sufficient for intracytoplasmic injection (ICSI), ICSI fails due to poor quality some cases. Contention remains regarding whether testicular offers any advantage...
