The female mammary gland tissue contains androgen receptors (testosterone is an androgen). So this tissue is sensitive to androgens, and they inhibit the estrogen-induced proliferation. The inactivation of the androgen receptor on the other hand leads to an accelerated growth of the pubertal mammary gland and to the upregulation of estrogen receptor α expression in female mice. See references 1-3.
And the androgen receptor also seem very important in the formation of the nipples, as testosterone here directs apoptosis in the forming breast tissue. Mice without a functioning androgen receptor were born without nipples. See reference 4 and 5 for details.
To answer your question shortly: Yes, androgen hormones (among them testosterone) have a profound influence on the female mammary gland.
