Figure 4. Effect of NAC on C. elegans fertility. The number of progeny produced by gravid worms treated with or without NAC was monitored (n=10). (A) Total number of progeny. Worms exposed to NAC produced significantly more progeny during their gravid period than that of untreated worms (B) Time-course distribution of progeny. NAC-treated worms produced more progeny on days 3 and 4 after egg-laying compared to that by untreated controls and extended their gravid period by 2 days. Asterisk indicates a significant difference (p<0.05 by Student’s t test). Error bars indicate SEM.
