I have not been following the castrati discussion closely so pardon me if I repeat something already covered.
The greatest effect of hormones on the voice is in development during childhood and early adulthood. Everyone is genetically determined to have a type of voice - soprano vs alto and tenor vs bass (ignoring the effect of training here). The presence or absence of hormones allows this development.
After development is complete, hormones can affect the range. In abnormally high doses the range can be more significantly affected. Women can feel the effect of progesterone's androgenic effects and the low level of estrogen prior to a menstrual period and after menopause can see a loss of top range. Hormone replacement can help the latter problem. Birth control pill effects vary by type of hormone an a woman's individual physiology.
I am not aware of tenors becoming basses with hormones, but I have found suggestions that upper ranges are affected by androgen excess.
It is difficult to give an all inclusive answer as effects vary.
