Lesson 4

Module 3—The Male and Female Reproductive Systems

Lesson Summary

 

In this lesson you considered the following focusing question:

  • What are the various effects of reproductive hormones? 

As a species we have managed to be able to control most aspects of our reproduction. Much of this control has come through major tinkering with our reproductive hormones. Hormones are used to prevent and assist pregnancies. Reproductive hormones are used in the treatment of conditions such as cancer and arthritis. Many chemicals that are used in products that promote improvement in our daily lives are now being identified as affecting our endocrine systems. Evidence now supports that the use of reproductive hormones, although beneficial to us at times, is not only having adverse effects on human health, but is having an affect on many other organisms as well.
