Histological section of the digestive gland and
ovotestis tissues of Bulimulus tenuissimus uninfected and experimentally infected with Angiostrongylus cantonensis.
Eighteen of those individuals were confirmed male (with fully developed testes), one was questionable (still with
ovotestis but also with large patches of testicular tissue, possibly in transition), and two appeared to have normal ovotestes.
The patient and a family member, along with the patient's pediatric urologist, confirmed that he had been diagnosed with OT-DSD at birth and had previously undergone left
ovotestis removal with subsequent prosthesis placement, an orchiopexy for an undescended right testicle, and correction of hypospadias, all taking place shortly after birth.
Among the
ovotestis, 46% were in ovarian position, 26% in labioscrotal fold, 24% in inguinal canal, 20%
ovotestis bilaterally.
Histopathological examination of the excised left gonad revealed features of an
ovotestis with both ovarian and testicular tissues present in addition to a gonadoblastoma on the base of dysgerminomas (Figure 4).
Histological examination of gonads revealed that few specimens exhibited intersex (
ovotestis) i.e.
Testis-like steroidogenesis in the
ovotestis of the European mole Talpa europaea.
Full development of the internal genitalia depends on the predominant function of that ipsilateral gonad,[sup.7,8] so that fallopian tubes are present with an ipsilateral ovary and likewise a vas deferens is always present adjacent to a testis.[sup.5] An
ovotestis contains both ovarian (found in the poles) and testicular tissue (found centrally).[sup.9] If there is a testes or an
ovotestis with predominant testicular function, the testes is likely to descend;[sup.10] commonly, however, the testicular portion of the
ovotestis is dysgenetic.
All hermaphroditic gonads had miscellaneous acini in which spermatids and spermatozoa prevailed, but small oocytes were also present on the wall (
ovotestis, Fig.
Kryptolebias marmoratus is unique among vertebrates due a self-fertilizing mode of reproduction utilizing a mixed gonad, the
ovotestis. To determine if genetics play a role in the development of the
ovotestis, a recessive sterile screen across two generations (ENU mutagenesis: n=307 F2 fish) was performed.
Inner surface of body wall and surface of
ovotestis slightly pigmented.
Os hermafroditas verdadeiros sao individuos com tecido testicular e ovariano ou combinados em uma unica gonada (
ovotestis) ou existentes em gonadas separadas (3).
First reported cases of intersex (
ovotestis) in the flatfish species dab Limanda limanda: Dogger Bank, North Sea.
El examen histologico reporto utero prepuberal, trompas de aspecto normal y
ovotestis bilateral (Fig.
