Can a Turner syndrome patient develop male characteristics artificially?
After a lot of research, I've finally found an answer.

In the case of humans, it is practically impossible. See this article from wikipedia:


  During gestation, the cells of the primordial gonad that lie along the urogenital ridge are in a bipotential state, meaning they possess the ability to become either male cells (Sertoli and Leydig cells) or female cells (follicle cells and Theca cells)...Once proper SOX9 levels are reached, the bipotential cells of the gonad begin to differentiate into Sertoli cells.


This part is just to clarify why it is not possible. In embryonic stage in turner syndrome patients (and females), since SOX9 is not expressed (due to absence of SRY), the bipotential gonad cells in the urogenital ridge (Müllerian/paramesonephric ducts) of embryo develop into female reproductive system i.e. become mature into that state. After this has happened, any amount of SRY cannot develop male reproductive system as all bipotential cells have differentiated into female reproductive system.

It is practically impossible, but virtually it can happen if you can insert Y chromosome or TDF in the bipotential cells of embryo. Practically, doing such experiments on embryo might not be possible (at least for now).

However, it only means that they can't develop primary sexual characters. Secondary sexual characters can, obviously, be developed by efforts as small as hormone injections. In fact, hirsutism is a condition in which females devlop hairs on chest, face, etc. and even beards! Its causes are as common as obesity. See this article:


  Some medications can cause hirsutism. These include danazol, which is used to treat women with endometriosis; systemic corticosteroids and fluoxetine (Prozac) for depression...Being obese causes increased androgen production, which can worsen hirsutism.


So, if a Turner syndrome patient wants a moustache or beard (just in case), it can be achieved by androgen injections too.
