Darwinian feminism respects our biology and fully explores it. Women have the right to understand the history (herstory?) including the evolutionary history that has shaped our bodies and minds. We need better information about our biological and hormonal natures.” Carcinoid tumors: Carcinoid tumors are a type of neuroendocrine tumor (NET) that grows from neuroendocrine cells. Neuroendocrine cells receive and send messages through hormones to help your body function. I don't know what Haselton's opinions on testosterone are, but she is definitely not here to tell us that hormones don't impact our behavior. She is here to say that there is a lot of hidden wisdom in the changes in behavior which happen across the ovulatory cycle (and the longer-term changes from adolescence to menopause), and we should not mess with it without considering carefully the consequences. She is not, for example, a big fan or using hormone therapy to, as she puts it, treat menopause as if it were a disease which needs to be cured. Irregular menstruation (periods): Several hormones are involved in the menstrual cycle. Because of this, an imbalance in any one or several of those hormones can cause irregular periods. Specific hormone-related conditions that cause irregular periods include polycystic ovary syndrome (PCOS) and amenorrhea. Each hormone-related condition can have several different possible causes. In general, the main conditions or situations that cause hormone imbalances include:

Primary healthcare providers can diagnose and help you manage many hormonal imbalances, but you may benefit from seeing an endocrinologist. If you have lower-than-normal hormone levels, the main treatment is hormone replacement therapy. Depending on which hormone is deficient, you may take oral medication (pills) or injection medication.This book is well written, funny, and informative. Professor Haselton is excellent at explaining what her research means for you and me while maintaining scientific rigor. The one thing I missed was an apparent response to the arguments put forth by Cordelia Fine in her book “Delusions of Gender” who convincingly argues that hormones play a minor role (although she never says that the effects are non-existent).

Your pituitary gland is a pea-sized gland at the base of your brain, behind the bridge of your nose and directly below your hypothalamus. It consists of two lobes: the posterior lobe and the anterior lobe. Your pituitary gland releases several hormones — many of which control the functions of other endocrine glands. Dozens of medical conditions are caused by hormone issues. For most hormones, having too much or too little of them causes symptoms and issues with your health. While many of these imbalances require treatment, some can be temporary and may go away on their own. Some of the most common hormone-related conditions include: Parental investment theory - The sex that is required to invest more time and effort in bringing up children and that is biologically limited in number of children they can have will be selective in choosing their mate)Pituitary adenomas: Pituitary adenomas can cause an imbalance in any of the hormones your pituitary gland makes. For example, pituitary adenomas are the most common cause of acromegaly (excess growth hormone in adults). She calls herself a Darwinian feminist so the book is about the female human primate. It is a medical approach she takes, not anthropological or even all that sociological and while she does mention Stephen Jay Gould, she does not mention some of the classic zoological and anthropological accounts of human primate behavior, one of the first being the very daring and audacious book for its time (1967), The Naked Ape, by Desmond Morris in which Morris explains human sexual behavior from a biologist's perspective based on evolutionary principles—again, in 1967! I was disappointed and surprised Haselton, being an academician, left any mention of this book out. She also makes no reference to the works of Jared Diamond (The Third Chimpanzee). To me, these were glaring disappointing omissions. Then again, she explains early on, she is an “evolutionary psychologist”. Nonetheless, deference and solid research should include at least mention of these early researchers and writers.
