Objective: Fertility status evaluation in patients found azoospermic at the time of malignancy diagnosis.
Design: Case series follow-up.
Setting: University Hospital Sperm Banking service.
Patient(s): Male cancer patients found azoospermic between 1986 and June 2000.
Intervention(s): Patients were interviewed about their reproductive history and were invited for a free semen analysis.
Main Outcome Measure(s): Pregnancy rate (PR) and percentage of patients with viable spermatozoa in the ejaculate.
Result(s): Sixty-five patients were enrolled; 16 were lost at follow-up, 7 died, and 42 were followed to the end of the study. The median (range) time of follow-up for the 42 remaining patients was 9 years (2-14 years). Seventeen patients had wanted to father a child; 12 had a child (71%, 95% confidence interval [CI] 48%-88%). Semen analysis results were available in 11 patients. Resumption of spermatogenesis was documented in 9 cases (82%, 95% CI 53%-97%).
Conclusion(s): Spontaneous fertility recovery is frequent in patients who are azoospermic at the time of cancer diagnosis.

Investigating the correlation between micronucleus formation and male infertility has the potential to improve clinical diagnosis and deepen our understanding of pathological progression. Our study enrolled 2252 male patients whose semen was analyzed from March 2023 to July 2023. Their clinical data, including semen parameters and age, were also collected.

To investigate the impact of preoperative serum follicle-stimulating hormone (FSH) levels on the probability of testicular sperm retrieval, we conducted a study of nonobstructive azoospermic (NOA) men with different testicular volumes (TVs) who underwent microdissection testicular sperm extraction (micro-TESE). A total of 177 NOA patients undergoing micro-TESE for the first time from April 2019 to November 2022 in Shenzhen Zhongshan Obstetrics and Gynecology Hospital (formerly Shenzhen Zhongshan Urology Hospital, Shenzhen, China) were retrospectively reviewed. The subjects were divided into four groups based on average TV quartiles.

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).

Objective: To compare sperm retrieval rates (SRR), postoperative pain, testicular volume, and postoperative testosterone levels between equatorial incisional microdissection testicular sperm extraction (micro-TESE) and longitidunal incisional micro-TESE in nonobstructive azoospermic (NOA) patients.
Methods: Fifty NOA patients undergoing equatorial incisional micro-TESE were retrospectively assigned to group 1, while 50 patients undergoing longitidunal incisional micro-TESE were prospectively assigned to group 2. Demographic data, operative time, postoperative pain assessed via the visual analog scale, complications, SRR, and hormonal evaluations (FSH, LH, total testosterone) were recorded.
