| WBPhenotype:0000688 | sterile | Animals generate defective gametes, are otherwise unable to reproduce or they generate progeny that are unable to reproduce. | 
          
              | WBPhenotype:0001982 | cell membrane organization biogenesis variant | Variations in the process(es) involved in the assembly, transport, arrangement or disassembly of cell membrane structures or components compared to control. | 
          
              | WBPhenotype:0001944 | oocyte number decreased | A decreased number of celullarized haploid female germ cells (oocytes) are present in the gonad compared to control. | 
          
              | WBPhenotype:0001810 | oocyte septum formation variant | Animals exhibit variations in the partitioning of oocytes from each other compared to control animals. | 
          
              | WBPhenotype:0001969 | germ cell compartment morphology variant | Any variation in the form or composition of the compartments in the germline of females/hermaphrodites compared to control animals. In C. elegans these compartments contain a nucleus and are connected to a common cytoplasm (rachis).  These compartments eventually undergo cellularization and become oocytes. |
