Varicocele is commonly observed in male partners of infertile couples. The surgical ligation of varicoceles under microscopy can be safely performed by a skilled andrologist with most patients subsequently experiencing an improvement in semen quality. This is the first case in which obstructive azoospermia occurred after high inguinal varicocelectomy. The vas deferens was disrupted near the internal inguinal ring by fibrous tissue. A vasovasostomy was performed and semen parameters subsequently recovered.

Background: Non-obstructive azoospermia (NOA), the severe type of male infertility. The objective of this study was to evaluate the predictive accuracy of a prediction model of sperm retrieval failure with fine needle aspiration (FNA).
Methods: This study involved 769 NOA patients (dataset 1) undertaking FNA and 140 NOA patients undertaking mTESE (dataset 2).

Background: The presence of predominantly headless sperm in semen is a hallmark of acephalic spermatozoa syndrome, which is primarily caused by gene mutations in humans.
Purpose: To identify genetic causes for acephalic spermatozoa syndrome.
Methods: Polymerase chain reaction and Sanger sequencing were performed to define mutations in SUN5 and PMFBP1.

Objective: To study the reliability and effectiveness of the percutaneous sperm retrieval technique.
Methods: We retrospectively analyzed the records of 123 consecutive patients with obstructive azoospermia who underwent percutaneous sperm retrieval and intracytoplasmic sperm injection (ICSI) using Percutaneous Epididymal Sperm Aspiration (PESA) with or without a rescue Testicular Sperm Aspiration (TESA). We compared patients who had the first sperm retrieval ever and patients who had more than one sperm retrieval performed.

Background: To address knowledge gaps, this study aimed to investigate the involvement of inflammasomes in the etiology of azoospermia. This study focused on the gene expression of key inflammasome components, including , and .
Methods: We analyzed gene expression in blood and testicular tissue from patients with obstructive azoospermia (OA) and non-obstructive azoospermia (NOA).

Background: Vasoepididymostomy (VE) is an important surgical treatment to achieve natural conception for patients with obstructive azoospermia (OA), and only unilateral VE can be performed under certain conditions, such as OA patients with congenital unilateral absence of the vas deferens (CUAVD) and some acquired OA. There is a lack of relevant reports assessing the clinical outcomes of unilateral VE in OA patients with different causes. This study is aimed to describe the clinical features and evaluate treatments and outcomes of unilateral single-armed VE in OA patients.
