Abstract
It was found that an equal volume of oviduct fluid secreted at estrus is more stimulatory to spermatozoa than fluid produced at mid-cycle. In addition the oviduct produced at least twice as much fluid at estrus thereby making the total amount available to the spermatozoa in the oviduct much greater.
