Real-World Prescribing Patterns of Clomiphene Citrate for Male Infertility: A National Cross-Sectional Survey of Urologists in Türkiye

Background/Objectives: Clomiphene citrate (CC) is widely used off-label for male infertility despite limited evidence and inconsistent guideline recommendations. Although previous studies suggest variability in clinical practice, real-world data on prescribing patterns, patient selection, monitoring, and treatment success definitions remain limited. This study assessed CC prescribing patterns among urologists and identified factors associated with its use. Methods: A national, cross-sectional, web-based survey was conducted among urologists in Türkiye between November and December 2025. Of 1558 invited participants, 421 responded (27.0%), and 402 were included in the final analysis. The questionnaire was based on European Association of Urology and American Urological Association guidelines, refined through expert consensus, and pilot-tested. Multivariable logistic regression identified factors independently associated with CC use. Results: CC was used by 39.3% of respondents and was independently associated with private practice (odds ratio [OR] = 2.90, p < 0.001), greater professional experience (OR = 2.18, p = 0.002), and higher infertility case volume (OR = 2.27, p = 0.001). Substantial heterogeneity was observed in patient selection, dosing, monitoring, and success definitions. Treatment goals and perceived success definitions most frequently focused on laboratory-based endpoints, including semen parameters and testosterone levels, which were more frequently selected than pregnancy-related endpoints. However, spontaneous pregnancy was also commonly reported as a perceived success definition, whereas live birth was not separately assessed. An apparent indication paradox was observed for hypogonadotropic hypogonadism, which may reflect differing interpretations of functional versus irreversible hypogonadotropic states, and 31.6% of clinicians reported not routinely providing risk counseling. Conclusions: CC prescribing for male infertility remains heterogeneous among responding urologists and was associated with clinician experience, practice setting, and infertility case volume rather than standardized protocols. The predominance of laboratory-based endpoints, together with the frequent inclusion of spontaneous pregnancy as a perceived success definition and the absence of separate live-birth assessment, underscores the need for clearer terminology, standardized prescribing frameworks, structured risk counseling, and future studies incorporating clinically meaningful reproductive endpoints.
