A szerzők a központi idegrendszer, a tesztoszteron és származékainak szerepét tárgyalják a férfi nemi szervek méhen belüli fejlődésében. A férfi személyiségét meghatározó jellegzetességek először az emberi fejlődés magzati stádiumában jelentkeznek. Ezek kialakulása a gyermekkorban folytatódik. Pubertás után ezek növekvő mértékben válnak nyilvánvalóvá, és az egyén élete folyamán túlsúlyban maradnak. Az említett folyamatok mind a férfias fenotípust, mind a férfias magatartást befolyásolják. A tesztoszteron és származékai kontrollálják a férfi nemi szervek fejlődését. Hiányuk a női nemi jellegzetességek túlsúlyához vezet, a férfi nemi kromoszómakép ellenére. E jelenségek típusos példája a testicularis feminisatio klinikai képe. Jelen tanulmány különleges figyelmet szentel a reprodukciós szervek azon rendellenességeinek, amelyek a magzatokban ultrahanggal azonosíthatók. Ezen anomáliák legtöbbje antenatalisan hatásosan nem kezelhető. Azok a rendellenességek, amelyek a méhen kívüli életben sem gyógyíthatók, a terhességmegszakítás javallatát képezhetik, amennyiben ultrahangvizsgálattal a kora terhességben kimutathatók. Orv.

AbstractAmmonoid soft parts have been rarely described. Here, we document the soft parts of a perisphinctid ammonite from the early Tithonian of Wintershof near Eichstätt (Germany). This exceptional preservation was enabled by the special depositional conditions in the marine basins of the Solnhofen Archipelago. Here, we document this find and attempt to homologize its parts with various organs such as the digestive tract, reproductive organs, the mantle cavity with gills, and the hyponome, with differing degrees of reservation. Alternative interpretations are also taken into account. We suggest that the soft parts were separated from the conch either taphonomically (following necrolytical processes affecting the attachment structures) or during a failed predation, where a predator (fish or coleoid) removed the soft parts from the conch but then dropped them. This find is interesting because it adds to the knowledge of ammonite anatomy, which is normally hidden in the conch. The reproductive organs show traces of what might have been spermatophores, thus supporting the hypothesis that the microconchs represented the males.
