Slide4Steroid Hormones
Lipid-based
Lipid-soluble
Composed of four carbon-based rings
Diffuse through cell membranes
Bind to receptor proteins that start transcription
Slide5Anabolic Steroids
Compounds that are made to mimic male sex hormones
Come in the form of a pill, gel, cream, or injection
Used to build muscle mass in people who have anemia, osteoporosis, cancer, and HIV/AIDS
Used to treat problems that result in low testosterone levels
Slide6In Canada, a prescription is needed to legally obtain anabolic steroids
There is a market for illegal anabolic steroids
In most competitive sports, the use of anabolic steroids is banned.
Slide7Brief History
First created in the 1930’s as an attempt to create synthetic testosterone
During the Second World War, artificial testosterone was found to be helpful for the performance of soldiers
Became popular among Olympic, professional, and even high school athletes
By 1976, steroid use was banned from the Olympics
In 1988, the Anti-Drug Abuse Act was passed

Slide13Overall Effects
Can raise confidence, improve the absorption of minerals, lower body fat, and increase muscle mass
Gained muscle mass must be maintained through regular training
Steroid usage may also cause mood swings and depression (withdrawal symptoms)
Slide14Effects
Effects on the endocrine system and homeostasis
Slide15The Endocrine System
Over time, enzymes deactivate and break down a hormone that is no longer needed
One dose of an illegal anabolic steroid can be 10 to 100 times greater than a prescribed dose
Repeated injections make it difficult for the body to rid itself of extra hormones
The extra hormones put a strain on the body
Slide16Homeostasis
Many hormones are regulated by negative feedback loops
Regular injections of anabolic steroids disrupt these feedback loops
Slide17Conclusion
Slide18Conclusion
Anabolic steroids help build muscle mass, but only with regular training
Anabolic steroids can be legally prescribed to treat low levels of testosterone
Illegal steroids have disadvantages that outweigh their advantages
Excessive use can disrupt the endocrine system
