Gonadal Hormones and Retinal Disorders: A Review
Aim Gonadal hormones are essential for reproductive function, but can act on neural and other organ systems, and are probably the cause of the large majority of known sex differences in function and disease. The aim of this review is to provide evidence for this hypothesis in relation to eye disorders and to retinopathies in particular. Methods Epidemiological studies and research articles we...
متن کاملMenstrual variation in experimental pain: correlation with gonadal hormones.
BACKGROUND The results of studies examining the response to experimental pain during the menstrual cycle are conflicting because of differences in the definitions of the menstrual period, outcome measures and types of experimental pain stimulation. So far, there have been only a few studies correlating experimental pain with the levels of gonadal hormones over the menstrual cycle. Therefore, we...
متن کاملPreliminary evidence that gonadal hormones organize and activate disordered eating.
OBJECTIVE Eating disorders are more common in females than in males. Gender differences may be due to organizational (i.e. prenatal) and activational (i.e. post-natal) gonadal hormone effects that influence sex differences in behavior. This preliminary set of studies examined these effects by investigating relationships between eating disorder symptoms, prenatal testosterone exposure, and adult...
متن کاملEffects of gonadal hormones on central nitric oxide producing systems.
Nitric oxide-containing neurons are widely distributed within the CNS, including regions involved in the control of reproduction and sexual behavior. The expression of neuronal nitric oxide synthase is influenced by testosterone in male rat, and by estrogens in female. Moreover, nitric oxide synthase may co-localize with gonadal hormones' receptors. Gonadal hormones may influence nitric oxide s...
متن کاملGonadal hormones and gonadotrophins in healthy males beyond forty years.
OBJECTIVE To determine and compare the sex hormones, gonadotrophins and sex hormone binding globulin (SHBG) in healthy males of different age groups. METHODS One hundred eighty five consecutive healthy nonobese males of age 40-90 years were studied. Serum samples were assayed for total testosterone, estradiol, LH, FSH and SHBG estimation by radioimmunometric method. The subjects were divided ...
