Daraasad lagu qiimeeyay haweenka dhiigga ka soo baxa ee uurka ku dhaca ayaa lagu ogaaday in 6.5% ka mid ah maadooyinka ay soo bandhigeen uurka oo ay muujiyeen caddeyn ku saabsan cilladaha taranka. Daraasad ku saleysan baaritaanka loo yaqaan 'hysterosalpingraphic' ee lagu ogaaday dhaawacyada 'arcuate' ayaa lagu caddeeyay kororka luminta uurjiifka iyo dhibaatooyinka dhalmada ee khatarta ah ee haweenka ay saameeyeen. Woelfer wuxuu ogaaday in halista ilmo iska soo riddu ay ka sii badan tahay saddexda bilood ee labaad. Taas bedelkeeda, daraasad la sameeyay oo loo adeegsaday 3-D ultrasonography si loo diiwaangeliyo baahida uurka oo ku dhaca dadka dumarka ah ee loo yaqaan 'gynecological population' ma aysan helin wax caddeyn ah oo ku saabsan kororka khatarta dhalmada; Daraasaddan 3.1% ee haweenka ayaa leh dhiigga ka soo baxa ee uurka ka soo noqnoqda, taas oo ka dhigeysa inay tahay halista ugu badan ee soo noqnoqda ee soo noqnoqda ee uur
ilmaha iska soo rididda, dhalmada ka hor waqtiga iyo muuqaalka oo qaldan
