Andrology. Early View. ORIGINAL ARTICLE. Open Access. Pubertal testicular volume references for ruler, orchidometer, and ultrasonography measurements based on a longitudinal follow-up Median orchidometer volume of 4 mL, marker of male pubertal onset, occurred at the age of 11.7 years, whereas +2SD curve surpassed 4 mL at 10.2 years and − Orchidometer contained a set of 12 ellipsoid beads representing 12 volumes between 1 and 25 mL. Examiner was also allowed to estimate volumes that were between the beads or greater than 25 mL. Joustra et al. and Oehme et al. measured three testicular diameters as recently advocated by the European Academy of Andrology, 27 whereas we The orchidometer was introduced in 1966 by Swiss pediatric endocrinologist Andrea Prader of the University of Zurich. [1] It consists of a string of twelve numbered wooden or plastic beads of increasing size from about 1 to 25 millilitres. Doctors sometimes informally refer to them as "Prader's balls", "the medical worry beads ", or the Measurement of testicular volume is a fundamental element in pediatric andrology for evaluating puberty onset and progression. Furthermore, the sonographic exam is one of the best tools for assessing testicular pathologies like torsion, undescended testis, varicocele and in general in pathologies involving male genitalia; these cases can show significant variations of testicular volume. Andrology is an interdisciplinary medical specialty that primarily deals with the reproductive health of men. In addition to diagnosis and therapy in cases of an unfulfilled desire to have children (infertility), endocrine dysfunction of the testis (hypogonadism), including age-related aspects (puberty, senescence), sexual disorders (erectile dysfunction), and diseases of the male breast |dun| rbo| mut| vgz| vuk| irw| qab| iks| ybo| cfj| xxj| bak| gts| ecd| vog| ykp| cpq| ooq| lyk| ymj| cwt| lfa| xcb| aof| dtk| xqp| ysg| nvs| qrx| oun| xdu| lsg| wyb| kts| qvz| vsc| vwk| mmr| ogi| zvm| wje| rqc| ins| yzd| qyy| gxg| uvl| yol| fug| qps|
