Are Intersex conditions always apparent at Birth? 

Not always. Some intersex conditions cause babies to be born with genitals that cannot easily be classified as male or female (called ambiguous genitals). These intersex conditions are usually recognized at birth. The first four conditions listed above – congenital adrenal hyperplasia, 5-alpha-reductase deficiency, partial androgen insensitivity syndrome, and penile agenesis – are in this category. Other intersex conditions, including the last four conditions listed above – complete androgen insensitivity, Klinefelter syndrome, Turner syndrome, and vaginal agenesis – usually do not result in ambiguous genitals and may not be recognized at birth. Babies born with these conditions are assigned to the sex consistent with their genitals, just like others babies. Their intersex conditions may only become apparent later in life, often around the time of puberty.
