    • You may not really be able to tell for a little while longer. Sexual maturity is reached between 9 to 13 months in the male, and 18 to 24 months in the female so you might have to wait for sexual organs to "drop" in a male before you can tell either way... I used to have Spider monkeys. A veterinarian might be able to help a little better in your area.
