title: In vitro sperm maturation in sterlet, Acipenser ruthenus.
abstract: The aim of the study was to examine sperm maturation in sturgeon and to establish the localization of the maturation. We demonstrated that sperm maturation occurs in sturgeon outside the testes via dilution of sperm by urine. The process involves the participation of high molecular weight (>10kDa) substances and calcium ions.
