    Author : Arthur Aanesen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : GABA; spermatozoa; GABA transport; acrosome reaction; sperm motility; progesterone; protein kinase C; GAT-1; GAT-2; GAT-3; BGT-1;

    Abstract : The present project aimed at investigating the interaction between GABA and human spermatozoa under in vitro conditions. Our initial hypothesis was that human spermatozoa had specific binding proteins for GABA and that the binding of GABA to such binding sites could affect sperm function. READ MORE
