Importance of bicarbonate to the progesterone-initiated human sperm acrosome reaction
Anion channel bicarbonate sperm acrosome reaction
2009/2/13
Progesterone, a putative in vivo initiator of the human sperm acrosome reaction (AR), has previously been shown to act at the sperm plasma membrane to initiate the AR in vitro. Here, we have investi...
