Objective: The aim of this study was to compare depression and sexual dysfunctions observed in primary and secondary infertile patients. Material and method: The study was performed in 39 primary and 31 secondary infertile male patients. Male sexual health was evaluated using the International Index of Erectile Function (IIEF) score and depression with Beck Depression Inventory (BDI). Results: Mean age of the participants and their partners were 31.54 ± 5.37 (range, 24-48 yrs), and 28.16 ± 5.58 (range, 20-46 yrs) years, respectively. Mean duration of their marriage ranged between 1 and 17 years (mean, 5.06 ± 4.15 yrs). A statistically significant intergroup difference was detected between groups as for BDI scores (p = 0.015; p < 0. 05). BDI scores of the primary group were significantly lower than those of the secondary group. A statistically and extremely significant difference was detected between IIEF scores of the groups (p = 0.006; p < 0.01). IIEF scores of the primary infertile group were higher than those of the secondary group. Conclusion: Our study, frequency of the depression and erectile dysfunction seen in the patients with secondary infertility was seen significantly higher than the patients with primary infertility.KEY WORDS: Infertility; Male sexual dysfunction; Depression; Secondary infertile man. clear definition of this time, the 12 months period is also accepted for the secondary infertility by many authors. Diagnosis of infertility can be made in nearly 15% of the couples who want to have a baby and primary or secondary infertility are detected in 90 and 10% of them (3). One of the basic and primitive instincts in human beings is reproductive instinct. Reproductive deficiency frequently creates a social stigma, which is perceived as a disgraceful condition (4). Infertility emerges from a sudden and unexpected life crisis, which can be diagnosed in the long run. It results in excessive stressful problems, which strain adjustment mechanisms (5). Studies analyzing the association between infertility and psychological functions have used one of the following models. One of them is psychological infertility model, which asserts the role of an existing psychopathology on the etiology of infertility and the other model (psychological result) claims that psychological problems arise as a result of infertility (6). Recently direct correlation of mental stress with infertility problems and its impact on the outcomes of infertility treatment has been demonstrated. For example it has been revealed that during natural disasters like earthquakes, sperm quality activities of seminal plasma superoxide dismutase and arginine decrease, and nitric oxide levels increase in men under stress (7,8). Since psychiatric disorders are more frequently analyzed during infertility investigations, scales specific to infertility process haven't been developed yet (9). In developed countries, it appears to be appropriate to take a detailed history about psychological status of the infertile couple. The rationale of this appr...
