Gender Help

[AlanLynch]

I always am looking on toad websites to figure out the gender of my toad, but to me both genders look exactly like my toad. So, can you help me figure out the gender of my toad? I think she's a female hence the name Lola, but I'm not sure anymore. She never chirps when picked up and I've never heard her chirp, but it looks like she has a gray throat. I'm stumped. Her are some pictures to help you guys. I don't really even know what species she is. Though I'm pretty sure it's American. (She was caught in Cook County Illinois, so she's either an American or Fowler)
