Context: Testosterone is a steroid hormone produced primarily in the testes in men and ovaries in women, playing crucial roles in androgenic, anabolic, and psychological functions, including muscle growth, bone formation, erythropoiesis, risk-taking, and aggression, making it important for athletes. Sports performance is linked closely to testosterone level, prompting athletes to explore legal and illegal ways to boost testosterone. This review examines testosterone physiology and legal strategies for optimizing testosterone levels in athletes, as well as their practical applications. Evidence Acquisition: Database search. Study Design: Narrative review. Level of Evidence: Level 5. Results: Maintaining healthy testosterone levels requires energy balance and optimal nutrition with adequate macronutrients and micronutrients, especially for athletes prone to dieting and food restriction. Testosterone boosters are marketed widely but lack strong evidence for efficacy and may pose risks. While some substances show promise, further research is needed. Sleep is critical as testosterone secretion is linked to the rapid eye movement phase, highlighting the need for proper sleep hygiene and addressing sleep disorders. Moderate-to-high intensity free-weight resistance exercises are most effective for increasing testosterone, while the effects of sexual activity remain unclear. Endocrine-disrupting chemicals can lower testosterone levels and should be avoided. While cold-water immersion may decrease testosterone, sauna bathing appears to be neutral. Radiofrequency electromagnetic radiation from modern electronic devices may harm the hypothalamic-pituitary-gonadal axis, warranting limited use. Over-the-counter analgesics, such as nonsteroidal anti-inflammatory drugs and acetaminophen, may decrease testosterone levels, suggesting cautious use. Seasonal changes in testosterone levels require further study. Testosterone-optimizing strategies excluding banned substances may aid in treating functional low testosterone or reducing harm in anabolic-androgenic steroid users. Conclusion: Educating athletes on safe and effective strategies to increase testosterone is crucial, with ongoing research needed to explore additional methods.

Abnormal uterine bleeding and fertility challenges secondary to long COVID: A case report
Menstrual irregularities and abnormal uterine bleeding have been increasingly reported following severe acute respiratory syndrome coronavirus 2 infection, likely due to viral-induced endocrine disruption and immune dysregulation. A woman in her late 30s, with previously regular menses, developed persistent abnormal uterine bleeding after recovering from coronavirus disease 2019. Lab work-up over the next 2 years demonstrated high follicle-stimulating hormone, low anti-Müllerian hormone, low estrogen, and borderline antinuclear antibody titers. A pelvic ultrasound showed low antral follicle count, and she had challenges with fertility preservation. The patient was suspected of having an exaggerated immune reaction to severe acute respiratory syndrome coronavirus 2 infection with her strong family history of autoimmune disease and borderline antinuclear antibody, which may have led to an autoimmune-induced premature ovarian insufficiency. This case highlights the need to recognize post-viral menstrual irregularities and endocrine dysfunction as a potential consequence of coronavirus disease 2019. Clinicians should consider postinfectious endocrine disturbances in patients with new-onset abnormal uterine bleeding or infertility and evaluate for immune-mediated mechanisms when appropriate. Further research is needed to elucidate the long-term impact of coronavirus disease 2019 on reproductive health.
