Background: To determine the differences in sperm quality and results of intracytoplasmic sperm injection (ICSI) cycles between three groups of male factor infertile couples: oligozoospermic, obstructive azoospermic and non-obstructive azoospermic.
Materials And Methods: In this prospective cohort study, 628 male factor infertile couples who underwent ICSI cycles from April 2004 to March 2006 were enrolled. Three hundred fourteen oligozoospermic patients (group I), 180 obstructive azoospermic patients (group II) and 134 non-obstructive azoospermic patients (group III) were included. Fertilization, cleavage, implantation and clinical pregnancy, early abortion rates were assessed. Chisquare and analysis of variances with Post Hoc (Tukey test) were used for data analysis.
Results: Fertilization rates were significantly different in the three groups (group I: 66.6%; group II: 51.8%; group III: 47.7%; p=0.004). There were differences in the implantation rates (I: 19.5%; II: 17.6%; III: 6.4%; p=0.001). The cleavage rates were found to be 55.1% (group I), 47.5% (group II), 45.5%(group III), respectively. The clinical pregnancy rate was the lowest in the third group (I: 37.6%; II: 28.9%; III: 13.4%; p=0.001). There was no significant difference in early abortion rates between the three groups: (I: 10.7%; II: 9.8%; III: 8%; p=0.776).
Conclusion: It can be concluded that patients with oligozoospermia may benefit the most from ICSI treatment. ICSI cycles which use spermatozoa from non-obstructive azoospermic patients have a lower chance for successful outcome. The results of this study suggest, in cases of failure to achieve pregnancy after 1 or 2 cycles in non-obstructive azoospermic patients, embryo donation would be a better alternative.

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.
