Quantifying Sexual Constitution: Abraham Myerson's Endocrine Study of Male Homosexuality, 1938-1942

Using the new medical science of endocrinology, scientific sex researchers in the 1920s and 1930s began studying sex hormone excretion as a means to search for the biological basis of human sexuality. One of these researchers was Abraham Myerson, a leading psychiatrist and researcher from Boston who conducted a series of innovative endocrine experiments between 1938 and 1942 in an effort to establish a relationship between sex hormone excretion patterns and homosexuality in men. While prevailing cultural models of heteronormativity identified male homosexuality as an abnormal case of biological femininity in men, Myerson’s framework and experimental research transcended this limiting duality of sexual biology. Adopting the theory of bisexuality, he argued that all men possessed a natural variability of masculine and feminine traits in their biological, social, and sexual characteristics, and that the disparity among these traits could be quantified and understood using sex hormones. In reconstructing Myerson’s research methods and data analysis, this paper uncovers how he established a distinctive diagnostic method and classification system for male homosexuality and illuminates how he conceptualized and categorized male sexuality as quantifiable and independent of personality.

Laparoscopic Treatment of Adrenal Tumors: A Single-Center Experience with 58 Patients

Background.The aim of this study is to discuss the laparoscopic approach and assess the immunohistochemical expression profiles of synaptophysin, Ki-67, and inhibin and patient outcomes in adrenal masses through a series of cases treated at our institution.Method.The study was conducted on 58 patients who were diagnosed with adrenal masses. All cases were operated on laparoscopically for adrenal masses.Results.Both inhibin and synaptophysin were found positive in 45 patients (77,6%). Ki-67 was negative in 11 patients, whereas it was found positive in 42 with a rate of 1%. The size of the masses ranged from 1 up to 9 cm (mean 4,3 ± 1,5). Urine hormone excretion was measured within normal ranges in 47 out of 58 patients (81%). Most of the diagnosed patients were harboring Cortical Adenoma (n: 38; 65,5%). All of the masses were successfully resected without complication except 3 patients. Because of complications of bleeding, the operation was converted to open surgery for 2 patients.Conclusion.Morbidity, mortality, and healing were comparable, regardless of tumor size, yet involvement in both laparoscopic and adrenal surgery was required. Our results suggested that laparoscopic adrenalectomy should replace open surgery as the standard treatment for most adrenal masses.

Stress and Fatigue in Operators Under Radiofrequency Electromagnetic Radiation and Shift Work

Summary The aim was to study the effect of radiofrequency electromagnetic radiation (EMR) on stress indices, health complaints and fatigue of operators working fast-rotating extended shifts. Working conditions, job content, job control, social support, health complaints and fatigue were followed in 220 operators, 110 exposed to EMR and 110 control operators, matched by age and sex. The EMR was measured and time-weighted average (TWA) was calculated. The excretion rates of stress hormones cortisol, adrenaline and noradrenaline were followed during the extended shifts in 36 operators, working at different levels of exposure and 24-hour exposure was calculated. The exposed group pointed more problems with the working conditions, including EMR, noise, currents and risk of accidents, more health complaints and higher level of fatigue. The most common health complaints were mental and physical exhaustion after work, pains in the chest, musculoskeletal complaints, headache, and apathy. High level EMR exposure (TWAmean = 3.10 μW/cm2, TWAmax = 137.00 μW/cm2) significantly increased the 24-hour excretion of cortisol and noradrenaline, whereas the increase of adrenaline excretion did not reach significance, as well as hormone excretion rates under low level exposure (TWAmean = 1.89 μW/cm2, TWAmax = 5.24 μW/cm2). In conclusion, higher number of health complaints, higher stress hormone excretion rates and fatigue were found in operators under EMR.
