Microdissection testicular sperm extraction (microTESE) is considered the gold standard method for surgical sperm retrieval among patients with non-obstructive azoospermia (NOA). In this review, we will discuss the optimal evaluation of NOA patients and strategies to medically optimize NOA patients prior to microTESE. In addition, we will also discuss technical principles and pearls to maximize...

PURPOSE Although optimizing endogenous testosterone production before testicular sperm extraction is commonly practiced, whether improved preoperative testosterone levels enhance sperm retrieval remains unclear. We evaluated the influence of preoperative medical therapy in men with nonobstructive azoospermia before microdissection testicular sperm extraction. MATERIALS AND METHODS A total of ...

Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist. In the era of in vitro fertilization with intracytoplasmic sperm injection, surgical sperm extraction techniques can afford men with NOA biologic paternity. To provide a ...

In 220 consecutive patients with non-obstructive azoospermia, sperm retrieval was attempted by a combination of conventional and microdissection testicular sperm extraction (TESE). For sperm retrieval, 2-3 conventional biopsies were performed followed by a microdissection TESE in cases of negative conventional biopsies. During the surgery, the vasculature of the testis was assessed using the op...

BACKGROUND We compared the efficacy of microdissection testicular sperm extraction (microdissection TESE) and conventional TESE in patients with non-obstructive azoospermia (NOA) and related the positive sperm recovery to certain variables: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, testicular volume and histology. METHODS Sperm retrieval rates (SRR) in patients w...

Patients with non-obstructive azoospermia (NOA) were once considered to be infertile with few treatment options due to the absence of sperm in the ejaculate. In the last two decades, the advent of intracytoplasmic sperm injection (ICSI), and the application of various testicular sperm retrieval techniques, including fine needle aspiration (FNA), conventional testicular sperm extraction (TESE) a...
