In this session students will evaluate data on precocious puberty and try to find its underlying causes. Read this to the class or discuss it in your own words with them. Be sure that you cover these points: what causes normal puberty; the technical terminology of puberty; is a statistically significant difference in average age at puberty of 3, or 6 months biologically significant? Emphasize t...
1. Define the ages at which puberty is considered delayed in boys and girls. 2. Discuss the typical presentation and natural history of constitutional delayed puberty. 3. Compare the differential diagnosis of delayed puberty for causes other than constitutional delay in girls versus boys. 4. Recognize the psychological consequences of pubertal delay. 5. Describe the evaluation and treatment of ...
Onset of puberty was measured in 850 F2 Friesian x Jersey animals in a QTL discovery trial. Phenotypes for onset of puberty were defined by age at puberty based on endocrine profiles, and predicted proportion of mature live weight. A QTL analysis was conducted on the derived phenotypes using line of descent and half sib regression models. Results from the proportion of estimated mature live wei...
Abstract Background & Aims: The mean age of puberty is different from one country to another and the beginning time of puberty is influenced by various factors including environmental and genetic factors. This study was aimed at identifying the relationship between consumed food, physical activity and anthropometric indicators with precocious puberty among 5-8 years -old girls in the Ahwaz. ...

Objective: This study aimed to determine educational needs of 11-14 year old girls on sexual health in Dezful. Methods: This cross-sectional study was conducted on 810 middle school girls aging 11 to 14 in Dezful city in 2012....

Leydig cell testicular tumors are a rare cause of precocious pseudopuberty in boys. Surgery is the main therapy and shows good overall prognosis. The physical signs of precocious puberty are expected to disappear shortly after surgical removal of the mass. We report two children, 7.5 and 7.7 year-old boys, who underwent testis-sparing surgery for a Leydig cell testicular tumor causing precociou...
Intensity of human schistosomiasis infection increases with age, a peak being attained at early puberty. Hormones could be involved in the age-related changes in susceptibility to schistosomiasis. Male BALB / c mice were infected with Schistosoma mansoni either before or after puberty and worm numbers, cellular immune responses, hormonal levels and pathology analysed. Pre-puberty infected mice ...
The objectives of the present study were to obtain posterior densities of genetic parameters for scrotal circumference (SC), testicular volume (TV), BW, and age at puberty, to determine their correlations, and to evaluate the inclusion of these traits as selection criteria for sexual precocity in Guzerat bulls. Two-trait analyses were performed including records of SC, TV, and BW at 365, 450, 5...
