Abstract
RABBIT sperm only develop a capacity to fertilize after spending about six hours in the uterus or Fallopian tube. This has been shown by transferring sperm from the epididymis, an ejaculum, or the uterus to the Fallopian tube1. The following experiment shows that fertilizing capacity developed in the uterus is lost when sperm is treated with seminal plasma, but can be recovered after a further period in the female tract.
