Steroid Hormones

Lipid-based

Lipid-soluble

Composed of four carbon-based rings

Diffuse through cell membranes

Bind to receptor proteins that start transcription

Slide5

Anabolic 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

In 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.

Brief 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

In 1988, the Anti-Drug Abuse Act was passed

Overall 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)

Slide14

Effects

Effects on the endocrine system and homeostasis

Slide15

The 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

Slide16

Homeostasis

Many hormones are regulated by negative feedback loops

Regular injections of anabolic steroids disrupt these feedback loops

Slide17

Conclusion

Slide18

Conclusion

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
