The human body secretes and circulates some 50 different hormones. A wide variety of these chemical substances are produced by endocrine cells, most of which are in glands. The hormones then enter the blood system to circulate throughout the body and activate target cells. The endocrine system,...
Human reproductive system - Male Anatomy, Hormones, Reproduction: The male gonads are the testes; they are the source of spermatozoa and also of male sex hormones called androgens. The other genital organs are the epididymides; the ductus, or vasa, defer
Human hair follicles in culture express ER , although the distribution pattern by immunohistochemistry appears to be gender-specific [124]: ER immunoreactivity predominated in the female follicular der- mal papilla, which appears to determine the type of hair produced [125], and although basal ...

Human growth hormone may also be given to patients who are secreting abnormally low amounts on their own. Because of the complicated effects growth hormone has on the body, such treatments are generally restricted to children who would be pathologically small in stature without it. Growth hormone...
8 This is one of the most obvious clinical observations in both the human form of the disease and that of certain animal models. Because of this, gender and age are most likely linked to both cause andpathogenesis. Despite these facts, an explanation of this sexual predilection is elusive, ...
