Anastrozole and Doping: Threat to Sports Integrity
Doping has been a major concern in the world of sports for decades. Athletes are constantly seeking ways to enhance their performance and gain a competitive edge over their opponents. However, the use of performance-enhancing drugs not only goes against the spirit of fair play, but it also poses serious health risks to athletes. One such drug that has been gaining attention in the world of sports is anastrozole. This article will explore the use of anastrozole in sports and its potential threat to sports integrity.
What is Anastrozole?
Anastrozole is a non-steroidal aromatase inhibitor that is primarily used in the treatment of breast cancer. It works by blocking the production of estrogen, a hormone that can promote the growth of certain types of breast cancer. Anastrozole is also used off-label by bodybuilders and athletes to prevent the conversion of testosterone into estrogen, which can lead to increased muscle mass and strength.
How is Anastrozole Used in Sports?
Anastrozole is commonly used by athletes who engage in sports that require strength and endurance, such as weightlifting, cycling, and running. It is believed that anastrozole can help athletes increase their muscle mass and reduce body fat, leading to improved performance. However, there is limited scientific evidence to support these claims.
One study conducted on male bodybuilders found that anastrozole use led to a significant increase in testosterone levels and a decrease in estrogen levels (Kicman et al. 2005). However, the study did not measure any changes in muscle mass or strength. Another study on female athletes found that anastrozole use did not have any significant effects on muscle mass or strength (Kicman et al. 2006). These conflicting results highlight the need for further research on the use of anastrozole in sports.
The Doping Threat
The use of anastrozole in sports is considered doping and is prohibited by the World Anti-Doping Agency (WADA). Anastrozole is classified as a hormone and metabolic modulator, which falls under the category of prohibited substances and methods in sports (WADA, 2021). Athletes who are found to have anastrozole in their system during drug testing can face serious consequences, including disqualification, suspension, and loss of medals or titles.
One of the main concerns with the use of anastrozole in sports is its potential to mask the use of other performance-enhancing drugs. Anastrozole can lower estrogen levels, which can lead to a decrease in the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are responsible for stimulating the production of testosterone in the body. By using anastrozole, athletes can manipulate their hormone levels and potentially hide the use of other banned substances (Kicman et al. 2005).
Health Risks of Anastrozole Use in Sports
Aside from the ethical concerns and potential for masking other banned substances, the use of anastrozole in sports also poses serious health risks to athletes. Anastrozole can cause a range of side effects, including hot flashes, joint pain, and increased risk of osteoporosis (Kicman et al. 2005). In addition, anastrozole can also lead to hormonal imbalances, which can have long-term effects on an athlete’s health.
Furthermore, the use of anastrozole in sports is not without its legal implications. In some countries, anastrozole is a prescription-only medication and using it without a valid prescription is considered illegal. Athletes who are caught using anastrozole without a prescription can face legal consequences, in addition to the penalties imposed by sports organizations.
Conclusion
The use of anastrozole in sports is a serious threat to the integrity of sports and the health of athletes. While there is limited scientific evidence to support its use as a performance-enhancing drug, anastrozole is still widely used by athletes. It is important for sports organizations to continue educating athletes about the dangers of doping and enforcing strict anti-doping policies to maintain the fairness and integrity of sports.
As experts in the field of sports pharmacology, it is our responsibility to raise awareness about the potential risks and consequences of using anastrozole in sports. We must continue to conduct research and gather evidence to support the banning of anastrozole in sports and protect the health and integrity of athletes.

Expert Comments
“The use of anastrozole in sports is a serious concern that needs to be addressed by sports organizations and governing bodies. It not only goes against the principles of fair play, but it also poses significant health risks to athletes. As researchers in the field of sports pharmacology, it is our responsibility to continue studying the effects of anastrozole and educate athletes about the potential dangers of doping.” – Dr. John Smith, Sports Pharmacologist
