Hen Zemi is an OVA based on its original manga of the same title, which stands for Hentai Seiri Seminar (変態生理ゼミナール, Abnormal Physiology Seminar). Some people may describe this show as R-Rated version of Seitokai Yakuindomo, and it is partly true. However, instead of high school students making frivolous jokes about human sexuality, you will see a team of college students doing live-experience research on perverted behaviors of human under Professor Meshiya’s guidance.

Let's review the story:
First episode is pretty funny, but the name is too long and difficult! 6.0

This is an OVA about college students in a class where they are assigned sexual tasks by their professor. It is only 2 episodes long, and it worth the watch, but only if you're looking for ecchi. In every other aspect it fails to deliver, but is still OK enough to be watchable.

The genres would be ecchi and comedy. The comedy is exclusively amusing situations arising from sexual discussions. If pervy humor is your thing you will enjoy it. The ecchi moments are where this show really shines. In the first episode there is a sex scene with full bodies shown, but with the crotches ...
