This may be, and certainly it was intended to be, the first book on female hormones and their effects, especially written for men. The authors suggest that this short book with short chapters should not be read by women at all, though they could/should buy it for their man to read. There are already many books out there for a female readership but either none, or very few, are specifically for men. The idea is, that through plain language and progressive stepwise explanation of the endocrine (hormonal) changes of the menstrual cycle, the mechanisms will be fully understood and so an understanding of the disorders associated with hormones can be grasped. After explaining the hormones and their mechanisms, full but succinct overviews of commonly associated female problems are set out. They include problems like heavy periods, premenstrual syndrome (PMS), PMDD, polycystic ovaries, endometriosis, the menopause and HRT. After the descriptions of these disorders the authors explain how treatments may or may not work and how these hormonally-related problems can be controlled without drugs, with drugs, with hormones and occasionally with surgery. The authors have experience of many thousands of patients over a time period, and between them more than 80 years of medical practice in this specialty; so who better to address this topic? Importantly, they present these biological phenomena scientifically but in very down to earth terms; they also present how these disorders impact not only on the woman herself but on the family, colleagues, and, the main focus, her male partner. It also addresses how males can be sympathetic to their partner's problems, indeed, this is really the main objective of making men aware of HerHormones!
