Biomphalaria tenagophila é um hermafrodita simultâneo cujo investimento na função masculina foi avaliado pela contagem de espermatozóides do ovoteste e da vesícula seminal, sob diferentes condições experimentais, durante o processo de cópula. Foi criada uma nova técnica para contar espermatozóides separados em uma solução de alquilbenzeno sulfonato de sódio. Em todas as condições experimentais, a vesícula seminal teve mais do dobro de espermatozóides do ovoteste: da ordem de uma centena de milhar para três ou quatro centenas de milhares. Há evidências de que os espermatozóides transferidos no processo de cópula procederam da vesícula seminal do doador e que o equilíbrio do número de espermatozóides na vesícula seminal era restabelecido em menos de 24 horas. 2017-12-07T04:28:25Z 2017-12-07T04:28:25Z 1998 Artigo Rev.
