We examined the morphology of male genitalia six Muridae and five Cricetidae in Muroidea focusing on medial lateral bacular mounds, as well their ossification patterns to discuss diversity movement mechanism trident structure. All species possessed a mound two which collectively formed In species, was ossified or consisted cartilage, while mounds were composed soft tissue. By contrast, both spe...

Steroid 5-alpha-reductase 2 deficiency is a rare disorder leading to male pseudohermaphroditism, a condition characterized by incomplete differentiation of male genitalia in 46,XY patients. Here, we report a case of a 21-year-old woman from Ardabil who presented with primary amenorrhea, ambiguous genitalia, and lack of breast development. All of the serum hormone profiles were normal except for...

Sex determination in infants and children with ambiguous genitalia usually necessitates time-consuming and costly karyotyping .We have evaluated a simple,rapid and reliable method of postnatal sex determination by amplification of X and Y specific microsatellite markers DXS6797 and SRY respectively by polymerase chain reaction(PCR). Three probands M78, M59 and M61 with ambiguous genitalia were ...

Denys-Drash syndrome (DDS) and Frasier syndrome (FS) are caused by mutations of the WT1 gene. These disorders are characterized by renal disease, abnormality of male sex differentiation, and Wilms' tumor and gonadoblastoma. There have been few reports on gonadal function in a large series of patients with mutations of the WT1 gene. Here, we evaluated the relation between gonadal function and th...

Tocama huangjianbini sp. n. is described from Fujian province, China. The new species differs its known congeners by apex of parameres male genitalia rounded and without setae.

We investigated the evolution of the male genitalia of species of Limnebius (Coleoptera, Hydraenidae). This genus is very homogeneous externally but characterized by highly diverse male genitalia, which are in some cases extraordinarily complex. We reconstructed a molecular phylogeny for 70 of the c. 150 known species of the genus with six fragments of mitochondrial and nuclear genes. We found ...

A new species of the genus Domene Fauvel, 1873-D. viriatoi n. sp.-is described from a granitic natural cavity in Serra da Estrela, Portugal. This subterranean species is diagnosed and compared with closely related species from the Iberian endemic subgenus Lathromene Koch, 1938. The external morphology and male genitalia are illustrated and information on the species` ecology is presented. A dic...
