“…For maturational stage, Tanner’s self-evaluation method of pubertal maturation was used [ 26 ], which consists of choosing the stage that best suited each child, based on one of the images on a card that ranged from grade one to five (1 = pre-puberty; 2–4 = puberty; 5 = post-puberty). This is a non-invasive, reliable, and valid indicator of biological maturation [ 27 , 28 ].…”

Background: This study aims to analyze the effect of physical activity practice on the postural control state of school children. If such an effect was detected, the second aim of the study was to identify which specific capacities of postural control benefited the most from physical activity. Methods: A cross-sectional study was performed using a convenience sample of 118 healthy children (54 girls) with a mean age of 10.3 ± 1.2 years. Their weight and height were measured. The accelerometric assessment of balance included four different tests in static balance and walking. Results: Physical activity habit prevalence was 38.9% in girls and 60.9% in boys, and its frequency was 2.3 days per week in girls and 2.8 days in boys. The active children obtained lower accelerations, but the active and sedentary girls showed lower accelerometric values than the active boys. The logistic regression analysis demonstrated the influence of sex on the accelerations of the body (p < 0.001), regardless of the habit of physical activity. Conclusions: Active children have better postural control than sedentary children, although sedentary girls have better balance than active boys. Therefore, physical activity practice seems to favor a more efficient development of postural control, but it cannot level or reverse the effect of the neurophysiological factors that are conditioned by sex.

“…This age is thought to correlate with Tanner Stage 3 or midpuberty in individuals AMAB. 15 Tanner Stage 3 precedes spermarche and the emergence of significant secondary sexual characteristics, 16 plus age-appropriate sexual activities, such as masturbation. The changes associated with puberty would become obvious to a boy at this stage and might be distressing for those who experience MtE gender dysphoria.…”

“…Thirteen years of age was chosen as the division point in this study because that age is thought to correlate with Tanner Stage 3 or midpuberty in adolescents AMAB. 15 This stage is partially defined by first enlargement of the penis and expanded pubic hair growth, making the changes of puberty obvious to the boy. It precedes or marks the onset of spermarche, the development of sperm, voice changes, and other significant secondary sexual characteristics.…”

Exposures to information about castration and emotional trauma before puberty are associated with men’s risk of seeking genital ablation as adults

Background Little is known about childhood experiences, outcomes, and self-recollections of those men who were voluntarily castrated as adults. Aim The study sought to determine how learning about castration before and after 13 years of age is associated with differential childhood experiences, outcomes, and self-recollections of those who were voluntarily castrated as adults. Methods We designed a survey of voluntarily castrated individuals, who learned about castration before and after 13 years of age. Our survey consisted of both validated questionnaires and questions. Data were from 208 individuals. Both descriptive and quantitative statistics were performed. Outcomes Learning about castration before 13 years of age is associated with more adverse childhood experiences (ACEs) such as being threatened with castration and other forms of emotional, physical, and sexual trauma. Results As compared with those who learned about castration after 13 years of age, those who knew about castration earlier were more likely to have self-injured their penis (χ21 = 5.342, P < 0.05), had thoughts of performing self-castration (χ21 = 10.389, P < 0.01), witnessed animal castration (χ21 = 10.023, P < 0.01), been threatened with castration as a child (χ21 = 21.749, P < 0.001), had childhood physical trauma (χ21 = 4.318, P < 0.05), had childhood emotional trauma (χ21 = 3.939, P < 0.05), and had childhood sexual trauma (χ21 = 5.862, P < 0.05). Clinical Implications Mental health screening and support should be offered to any men seeking emasculating procedures in line with the World Professional Association of Transgender Health’s Standards of Care Version 8. Strengths and Limitations This study had a large sample size and used a validated questionnaire to evaluate for ACEs. The average age of respondents was above 50 years of age, which may increase recall bias. Conclusion Understanding how ACEs influence the age when some eunuchs first desire, pretend, and become castrated can help clinicians develop better assessments and treatment protocols for individuals with male-to-eunuch gender dysphoria, and other conditions in which emasculating medical procedures are requested.

“…In the United States, puberty has begun in the average female by age 13 and in the average male by age 14. 67 As a result, the majority of high school sport athletic teams will be composed of pubertal or postpubertal children. The same set of heat-acclimatization guidelines can be used for athletes at all competitive levels in the secondary school system (ie, freshman, junior varsity, and varsity).…”

Objective To provide best-practice recommendations for developing and implementing heat-acclimatization strategies in secondary school athletics. Data Sources An extensive literature review on topics related to heat acclimatization and heat acclimation was conducted by a group of content experts. Using the Delphi method, action-oriented recommendations were developed. Conclusions A period of heat acclimatization consisting of ≥14 consecutive days should be implemented at the start of fall preseason training or practices for all secondary school athletes to mitigate the risk of exertional heat illness. The heat-acclimatization guidelines should outline specific actions for secondary school athletics personnel to use, including the duration of training, the number of training sessions permitted per day, and adequate rest periods in a cool environment. Further, these guidelines should include sport-specific and athlete-specific recommendations, such as phasing in protective equipment and reintroducing heat acclimatization after periods of inactivity. Heat-acclimatization guidelines should be clearly detailed in the secondary school's policy and procedures manual and disseminated to all stakeholders. Heat-acclimatization guidelines, when used in conjunction with current best practices surrounding the prevention, management, and care of secondary school student-athletes with exertional heat stroke, will optimize their health and safety.
