Hormones involved in sexual interest and in the changes of puberty include all of these except:

I found the exercise on the internet. These were the choices:
A)testosterone
B)estrogen
C)DHEA
D)ghrelin

The only hormone that's not involved in puberty is ghrelin, although, there are studies that do demonstrate a relation between ghrelin and sexual interest in mice.
Testosterone and estrogen are clearly realated to puberty and the DHEA is a precursor in the biosynthesis of the testosterone and estrogen.

Ineed the answers so i can you
