Answer: The Testes.
Explanation: The Testes produce sperm as well as testosterone
God I read this so long ago but assuming Bob is the guy accused of beating the white guy's wife, I think the book lets the reader know that he's left handed through Atticus's demonstration when Atticus threw something at Ewell and he caught it with his left hand. Atticus then asks why he didn't catch it with his right and then Ewell says he hurt it when he was younger.
The guy was suffering in life but he still had love and care for his
sister to say happy birthday. It shows how mental health is not affected
by how you live your life. It's not affected by a lavish life but
rather its what your mind thinks is what your mental health leads to.
