Aims: We aimed to investigate fertilization rates, quality of embryo, pregnancy and live birth rates, endocrine, sexual function, psychological status and quality of life of cases diagnosed with Klinefelter syndrome (KS). Methods: Clinical findings, hormone values and semen analyses in patients with nonmosaic KS (Group 1, n=121) and those with non-genetic nonobstructive azoospermia (NOA) (Group 2, n=178) were retrospectively analyzed. Sperm retrieval outcomes with microdissection testicular sperm extraction (micro-TESE), fertilization rates and embryo quality, pregnancy, abortion, and live birth rates were compared. Sexual functions were assessed using IIEF-15, quality of life was evaluated, and psychological status was assessed. Results: There was no difference in terms of age between groups. Sperm retrieval rates was 38% and 55.6% in Group 1 and 2, respectively (p=0.012). Sperm retrieval rates were higher in Group 1 before 31.5 years than in Group 2 (AUC=0.620, 0.578). Compared to Group 2, the fertilization rate was low in Group 1, whereas embryo quality was similar. Live birth rates were 12.5% and 23% in Group 1 and 2, respectively (p=0.392). The education level, libido, erectile functions, and general health satisfaction were lower in Group 1 than in Group 2 (buraya p değeri yaz). Depression and anxiety levels were higher in Group 2 than Group 1 (p değeri yaz). Conclusion: Higher sperm retrieval rate has been achieved in group 1 younger than 31.5 years. Similar embryo quality is provided between groups. Sexual dysfunction and psychiatric problems were higher in Group 1, with lower satisfaction and general health than Group 2. Patients with KS should be monitored not only with their reproductive functions but also with their general health status.

Aims:Erectile dysfunction (ED) is a common condition affected by many factors. We aimed to show the impact of the metabolic syndrome (MeTS) on male sexual function based on VAI and the impact of increased levels of the VAI was investigated in patients with ED among the patients with and without MeTS. Methods:Participants who met MeTS criteria (Group 1, n=96) and without MeTS (Group 2, n=189) were included in this cross-sectional study. The MeTS diagnosis was made in the presence of at least three of the following criteria: serum glucose level higher than 100 mg/dl, HDL cholesterol level below 40 mg/dl, triglyceride level greater than 150 mg/dl, waist circumference greater than 102 cm and blood pressure greater than 130/85 mmHg. Demographic data were recorded; biochemical and hormonal tests were measured. Erectile and other sexual function scores were recorded. The VAI was calculated using the [(WC/39.68)+(1.88xMI)]xTG/1.03x1.31/HDL formula. Results:Mean age, smoking volume, T and T/E2 ratios of the groups were similar (p>0.05). Mean VAI was two-fold higher in patients in Group 1 (p<0.001) and erectile function score was lower in Group 1 than Group 2 (p=0.001). Other sexual function scores were similar (p>0.05). The METS was associated with an increased risk of ED (p=0.001). Logistic regression analysis showed that each integer increase of the VAI was associated with a 1.4-fold increased risk of ED (p<0.001). Higher T values were associated with a better erectile function (p=0.03). For the VAI=4.33, receiver-operating characteristic analysis showed a sensitivity of 89.6 % and specificity of 57.7 %. Conclusion:Compared to non-MeTS, the presence of MeTS has emerged as a risk factor for patients with ED with high VAI levels while the other sexual functions are preserved. Management of ED patients with MeTS should cover a comprehensive metabolic and endocrinological evaluation in addition to andrological work up.
