Unless you are reading medical journals and cutting edge research, this book should be required reading for anyone teaching the laws of Niddah because, HOO BOY, it turns out that it's not just 1500 years ago that no one had a decent understanding about female genitalia.
Gross's book is brilliant and funny and delightful and she clearly has the best sense of humor and, in the process, she showcases critical developments in the last hundred or so years of scientific development and what it is we still just don't know.
It's a delightful reading experience, and an important first step in thinking about what (else) we should know about the way our own bodies work and just...don't.
