Short-term nonfrozen storage of mouse epididymal spermatozoa.

Six simple methods for short-term (up to 8 d), nonfrozen (5 to 20 degrees C) storage of mouse epididymides were compared with respect to the motility and fertility of spermatozoa. A high percentage of progressively motile spermatozoa was obtained from epididymis stored for 8 d at 5 degrees C in mineral oil (78.3%), covered with body fat (80.0%), or stored… CONTINUE READING
