My definition says "could produce gametes", not "can have offsprings". Re intersex; congenital anomalies do not define a category (if the term congenital anomaly offends you, I am using the WHO definition). Just like if we would say "humans have one head" we would be excluding congenital twins, or with "five fingers" we would be excluding polydactyly.
