It is well-established, through extensive peer-reviewed published research, that physical activity and exercise training can impact the reproductive endocrine system of women. This ground-breaking, comprehensive title presents a range of unique insights into the opposite question: how the reproductive endocrine system of women affects their exercise ability. More precisely, the thematic question explored in this work is: if exercise affects reproductive hormones, conversely then could the reproductive hormones have physiological effects unrelated to reproduction that influence the capacity of women to exercise? In exploring this question, the goal is to better understand the unique physiology of women and whether female sex hormones might account for some of the variance in physiological performance between amenorrheic and eumenorrheic women, and within women across the age span as they experience menarche to menopause. Sex Hormones, Exercise and Women: Scientific and Clinical Aspects synthesizes the research by exploring the physiology and psychology behind these occurrences. This novel title will not only be of interest to researchers, exercise scientists, graduate students, and clinicians; it will also serve as a source of valuable information for female athletes and their trainers in the context of preparing for competitions.

Covid complications less likely in women, thanks to their chromosomes
Sexual motivation is influenced by hormones such as testosterone , estrogen , progesterone , oxytocin , and vasopressin. In most mammalian species, sex hormones control the ability to engage in on the motivation to engage in sexual behaviours. Sexual motivation can be measured using a variety of different techniques. Self-report measures, such as the Sexual Desire Inventory, are commonly used to detect levels of sexual motivation in humans. Self-report techniques such as the bogus pipeline can be used to ensure individuals do not falsify their answers to represent socially desirable results. Sexual motivation can also be implicitly examined through frequency of sexual behaviour, including masturbation. Testosterone appears to be a major contributing factor to sexual motivation in male primates, including humans.
Sex hormones and chromosomes protect women from severe Covid-19 complications
Sex hormones , also known as sex steroids , gonadocorticoids and gonadal steroids , are steroid hormones that interact with vertebrate steroid hormone receptors. Their effects are mediated by slow genomic mechanisms through nuclear receptors as well as by fast nongenomic mechanisms through membrane-associated receptors and signaling cascades. Natural sex hormones are made by the gonads ovaries or testes ,  by adrenal glands , or by conversion from other sex steroids in other tissue such as liver or fat. In many contexts, the two main classes of sex hormones are androgens and estrogens, of which the most important human derivatives are testosterone and estradiol , respectively. Other contexts will include progestogens as a third class of sex steroids, distinct from androgens and estrogens.
Sex or reproductive hormones have multiple functions in both males and females. In general, they are responsible for the development of the secondary sex characteristics during puberty. Later in life, during adulthood, they are in charge of regulating the reproductive cycle. In females, sex hormones are releases from the ovary, regulate the menstrual cycle , and control endometrial growth.
