| | Defining male and female |
 | | In other cases, collectively known as Androgen Insensitivity Syndrome (AIS), genetic males (46 XY chromosomal makeup) may have female characteristics when a mutation of the gene that encodes for the androgen receptor results in resistance to androgen's masculinizing effects during development. |
 | | Through his clinical work with some 100 patients, Reiner said, those who are genetically male, with the 46 XY makeup, will tend to identify themselves as boys if they can react and respond to male hormone, and even if they are born without a penis, underwent surgical reassignment and were raised as girls. |
 | | Understanding male versus female development also could help provide new clues to diseases such as autism, which occurs most often among males, or depression, an illness that is more common among females. |
