Medical Treatment in Men with Infertility Can Be Misinterpreted as Doping Practice: A Case of Unintentional World Anti-Doping Agency (WADA) Code Violation

Introduction: Clomiphene, a selective estrogen receptor modulator (SERM), is a drug which is primarily used for the treatment of anovulatory infertility in female patients. Although as an off-label use, some authorities and physicians use this drug for the treatment of idiopathic oligoasthenospermia in male patients. Clomiphene has two isomers and multiple metabolites, and its cis isomer (Zuclomiphene) can be detected in urine for as long as eight months in some cases. Case Presentation: A 30-year-old male futsal player used clomiphene for infertility for two months. After 17 weeks from the last dose, his urine sample result came out as an adverse analytical finding for clomiphene. Despite the initial ruling on a four-year ban by the national anti-doping agency, the appeals committee reduced the athlete's ban to two years after receiving explanations from the athlete, his appropriate doping record, and the fact that no trace of other substances, such as anabolic androgenic steroids (AAS) was found in the player's sample. Conclusions: In this article, the authors try to show the importance of athletes' familiarity with the anti-doping code and try to emphasize the importance of the fact that athletes should receive therapeutic use exemption (TUE) if they take any drugs with doping potential.
