Brief Summary
Clomiphene (Clomid) is a drug FDA approved to treat female infertility, however, it is often used by men in an off-label setting to both treat male infertility and in a multitude of sports disciplines to increase performance. Study Objectives:
- Determine detection windows for clomiphene and its metabolites in urine following a medium-term administration
- Understand the effect of clomiphene administration on luteinizing hormone (LH), follicle-stimulating hormone (FSH), and serum testosterone (T) concentrations in a longitudinal manner
- Identify changes in current steroidal module of Athlete Biological Passport

Outcome Measures
Primary Outcomes (1)
The window of detection for the clomiphene parent compound and metabolites following a 30-day administration will be identified.
â—¦This will be determined as the amount of time following the final dose (day 30) until clomiphene nor its metabolites are no longer detectable in a urine sample.
Day 30 through end of study participation (minimum, Day 72)
Secondary Outcomes (2)
Effect of clomiphene administration on serum LH, FSH, and T levels for potential inclusion into a hematological-based longitudinal steroid profile.
Day 30 through end of study participation (minimum, Day 72)
Effect on current steroidal module of Athlete Biological Passport
Day 30 through end of study participation (minimum, Day 72)
Study Arms (1)
Clomid
EXPERIMENTALAll participants will be receiving Clomid and will follow the same study procedures.
Interventions
Participants will self-administer Clomid (50mg oral tablet) once daily for 30 consecutive days
