Welcome back! This module continues our discussion of the endocrine system and its control of homeostasis. In this series of videos, we consider how the endocrine system regulates the production of gametes (egg and sperm) in the female and male, respectively, as well as the production of the sex hormones. The things to do this week are to watch the 4 videos, to answer the in-video questions, to read the notes, and to complete the problem set. It will be most effective if you follow the sequence of the lectures on the reproductive system. Again please consult the notes for a more detailed summary of each topic. If you have not tried the problems sets, please do so. They will reinforce your understanding of the newly learned information by applying it. Since these problem sets are delivered in the same electronic format as the exams, by completing them, you will gain confidence in using the electronic test format.
