I've compiled a list of links that I think will help shed some light on this subject and aid in understanding terms that I use within the story:
Intersex True Hermaphroditism Childbirth in true hermaphrodite. HERMAPHRODITE
A true story of dual genitalia Do "real" hermaphrodites exist? If they are functional, could a true hermaphrodite become pregnant? The Intersex Society of North America (ISNA) Hermaphrodites in humans and animals And to make clear outside the story what exactly Elijah is, here is the technical terms:
Female pseudohermaphrodites have ovaries and exhibit an XX chromosomal pattern, but the external genitalia look masculinized. The most common cause is congenital adrenal hyperplasia (CAH), a condition in which the adrenal glands of the fetus produce relatively large amounts of androgens (male sex hormones).
