Scrotal Ultrasound in Male Infertility

Significance of inhibin B and anti-Müllerian hormone in seminal plasma: a preliminary study

“…In addition, many patients presenting an arrest of maturation of the germinal cells have normal levels of FSH. The testicular volume varies according to race (5); also, its evaluation by an orchidometer lacks precision (6). Other studies corroborated these results (7)(8)(9).…”

Ultrasonic Testicular Texture and Size in 444 Men from the General Population: Correlation to Semen Quality

“…New areas are therefore currently evaluated for diagnostic ultra sound, and the use of ultrasonography of the scrotum has now extended to asymptomatic individuals, i.e. for tenta tively screening for carcinoma in situ of the testis [7], and for evaluations in infertility [8]. Reports on materials comprising normal men are, however, scanty, and a nor mal material for ultrasonic texture of the testis does not exist.…”

Intérêt du dosage de l’inhibine B et de l’AMH dans le plasma séminal: étude préliminaire

“…Par ailleurs, un grand nombre de patients presentant un arret de maturation des cellules germinales Iors de la biopsie testiculaire ont un taux de FSH normal. Le volume testiculaire varie en fonction de la race [25] ; de plus la mesure du volume evalue & I'aide d'un orchidometre manque de precision, celle-ci peut etre faussee par repididyme ou le scrotum [22]. En revanche, Ezeh et al [10] montrent I'interet d'utiliser la combinaison de deux criteres histologiques : presence de spermatides dans le tissu testiculaire et score de Johnsen, base sur le nombre de spermatozo(des observes dans la lumiere des tubes seminiferes (sensibilite 93%).…”
