Functional Spermatogenesis Across Testicular Developmental Stages in Neomale Large Yellow Croaker (Larimichthys crocea) Revealed by Histology and Gonadal Specific Cellular Markers [PDF]

Biology
Gonadal development and spermatogenesis critically influence fish reproductive performance. Neomales (genetically female but functionally male) are indispensable for generating all-female populations, yet their spermatogenesis remains understudied.

Abdominal and gonadal mature cystic teratomas

Journal of Pediatric Surgery Case Reports, 2022
The estimated incidence of germ cell tumours (GCT), is approximately 0.9/100,000 population [1,2]. One type of germ cell tumour, known as a teratoma, is typically derived from primordial germ cells, which have the potential to differentiate into somatic cells [3].
