Objective: To determine the predictive factors for successful retrieval of sperm from testicles before microdissection-testicular sperm extraction (micro-TESE) in patients with Klinefelter syndrome (KS) in order to counsel these patients regarding the likelihood of findings sperm.
Materials And Methods: The study is a retrospective analysis of the records of 67 men with KS between April 2016 and August 2020. Serum luteinizing hormone, follicle stimulating hormone, testosterone, prolactin, and estradiol levels were investigated. Testicular volumes were measured by ultrasonography. TESE was noted as positive or negative.
Results: There were 32 (47.8%) micro-TESE-negative patients and 35 (52.2%) m-TESE positive patients. The age of the micro-TESE-negative (34.9 ± 5.1 years) patient group was significantly higher than the micro-TESE-positive (32.3 ± 4.7 years) group (P = .035).The left testicular volume values were significantly higher in the micro-TESE-positive group (P = .019). Follicle stimulating hormone, luteinizing hormone, and prolactin levels were higher in m-TESE-negative patients compared to micro-TESE-positive patients, and testosterone levels and testicular volume were lower in micro-TESE-negative patients compared to micro-TESE-positive patients. However, these differences were not significant. As a result of intracytoplasmic sperm injection (ICSI) performed on 31 couples, 20 pregnancies and 16 live births were obtained (51.06%).
Conclusion: Among the parameters examined in this study, the age of the patient with KS may be predictive for micro-TESE success. Counseling should be given that some patients with KS may have a child via micro-TESE-ICSI.

Department of Systems Design Engineering, Faculty of Engineering, University of Waterloo, Waterloo, ON, Canada.
Background: While expert optometrists tend to rely on a deep understanding of the disease and intuitive pattern recognition, those with less experience may depend more on extensive data, comparisons, and external guidance. Understanding these variations is important for developing artificial intelligence (AI) systems that can effectively support optometrists with varying degrees of experience and minimize decision inconsistencies.
Objective: The main objective of this study is to identify and analyze the variations in diagnostic decision-making approaches between novice and expert optometrists.
