[Gonadotropic adenomas].

Since the advent of immunohistochemical and cell culture techniques, the role of gonadotroph adenomas in hypophyseal disorders appears more important than formerly. A large part of "nonfunctional" adenomas in fact correspond to gonadotroph adenomas in vitro. These adenomas raise many clinical and biological questions since their presentation is not univocal. In addition, diagnosis of these adenomas is important since their spontaneous development leads to neuro-opthalmological complications, which presently are still too often the revealing manifestations of these adenomas.
