In humans, it was shown that females at the beginning stages of puberty had much higher kisspeptin levels than those females of the same age who had yet to begin puberty. It has been concluded that the activation of the GPR54/kisspeptin pathway is a catalyst that leads to puberty onset.
Complete androgen insensitivity syndrome (CAIS) is an AIS condition that results in the complete inability of the cell to respond to androgens. [1] [2] [3] As such, the insensitivity to androgens is only clinically significant when it occurs in individuals who are exposed to significant amounts of testosterone at some point in their lives.
