Testosterone delivery systems for women: present status and future promise.

In women, testosterone (T) is increasingly recognized as a steroid with multiple non-reproductive effects. Testosterone deficiency in menopausal women is more common than appreciated, particularly in patients on hormone replacement or with surgical menopause. Replacement of T is an established therapy for male hypogonadism, and as a result innovative new delivery systems have evolved to optimize physiologic delivery. However, in women, modalities of T replacement remain underdeveloped and at present provide artificial and/or supraphysiologic androgen levels. This review discusses the androgen replacement modalities presently available for women, and those being developed for future use.
