This is the second textbook ever published about male psychology, and it's definitely the most accessible to date (the other being The Palgrave Handbook of Male Psychology and Mental Health). There will be other books in this series published in the coming years that I think will be more specialized (and probably more technical), so if that interests you at all, I'd recommend picking this one up first. It's already been adopted by several universities (mainly in the UK).

It's about £35 in the UK and $50 in the US. I have no affiliation with the authors or anything like that, I just figured some people here might be interested. It's not that difficult of a read, and the material is pretty interesting.

One thing I like is that the target audience is not strictly academic. In addition to psychology majors and "intelligent laypeople", they are also targeting professionals and volunteers working with men in mental health and related fields. In fact the relatively cheap pricetag is so specialists working with men (who often have limited funds) can afford it. From what I can tell, basically every topic from drug and alcohol abuse, to autism and PTSD, is covered. There's even a special focus on things like education, the military, and employment.

Because the topic [of male psychology] was gaining as much interest outside of psychology as within, it made sense to make that book accessible to professionals outside psychology (e.g. counselors, coaches) and people working in a variety of related fields (e.g. volunteers and workers in charities dealing with men). In fact, we were finding that many non psychologists were more informed about men's psychology then were many psychologists, having gained insight from working in the varies charities that support men's mental health, or in some cases being users of those services. Many of those non-professionals are volunteers with limited income, and the black-and-white illustrations in this book are part of the effort to ensure that cost was not too much of an obstacle to finding out about male psychology.

I'm not going to link where all you can get it but I would encourage anyone who's interested to look up their options. It is available worldwide from what I've been able to tell.
