Is there any other method to sterile guys

Was inquisitive to know that beside using FUDR or fertility strains guys like fer-15/spe-9 etc is there any other potent method to induce sterility in a non-sterile stain of C.elegans !! Any response or advice would be highly appreciated ::slight_smile:

You can induce potent sterility by RNAi of any number of oocyte genes.

RNAi knockout of cdc 25.1 gene works well to the worms.
