Him. Temperature-sensitive sterile. Small brood size even at permissive temperatures; pick fertile animals and maintain at 15C. Worms lacking spe-45 function produce morphologically normal and motile sperm that cannot fuse with oocytes despite direct contact in the reproductive tract. spe-45 hermaphrodites and males are subfertile at 16C and sterile at 25C.
