Incidence of invasive breast cancer in women treated with testosterone implants: a prospective 10-year cohort study.

Background: Testosterone implants have been used for over eighty years to treat symptoms of hormone deficiency in pre and postmenopausal women. Evidence supports that androgens are breast protective. However, there is a lack of data on the long-term effect of testosterone therapy on the incidence of invasive breast cancer (IBC).

Subcutaneous Testosterone Anastrozole Therapy in Men: Rationale, Dosing, and Levels on Therapy.

This analysis was designed to determine the efficacy of anastrozole, an aromatase inhibitor, combined with testosterone in a subcutaneous implant in preventing elevated estradiol levels and the subsequent side effects of excess estrogen associated with testosterone therapy. It also allowed for the establishment of normative ranges of serum testosterone levels on subcutaneous implant therapy. The study participants were 344 men who were accrued to an institutional review board-approved cohort study between April 2014 and 2017.

Breast cancer treatment in women over the age of 80: A tailored approach.

Breast cancer treatment in women over the age of 80 remains a complex issue due to pre-existing comorbidities, therapy-related toxicities, and the lack of evidence-based data in this population, leading to both overtreatment and under treatment. The average life expectancy of an 80-year-old woman is 9.7 years and chronologic age alone should not be a factor in withholding therapy.

Effect of testosterone therapy on the female voice.

Objectives: This prospective study was designed to investigate the effect of testosterone, delivered by subcutaneous implants, on the female voice.

Methods: Ten women who had opted for testosterone therapy were recruited for voice analysis. Voices were recorded prior to treatment and at 3 months, 6 months, and 12 months while on testosterone therapy.

Testosterone and breast cancer prevention.

Testosterone (T) is the most abundant biologically active hormone in women. Androgen receptors (AR) are located throughout the body including the breast where T decreases tissue proliferation. However, T can be aromatized to estradiol (E2), which increases proliferation and hence, breast cancer (BCA) risk.

Reduced breast cancer incidence in women treated with subcutaneous testosterone, or testosterone with anastrozole: a prospective, observational study.

Objectives: There is evidence that androgens are breast protective and that testosterone therapy treats many symptoms of hormone deficiency in both pre and postmenopausal patients. However, unlike estrogen and progestins, there is a paucity of data regarding the incidence of breast cancer in women treated with testosterone therapy. This study was designed to investigate the incidence of breast cancer in women treated with subcutaneous testosterone therapy in the absence of systemic estrogen therapy.

Testosterone therapy in women: myths and misconceptions.

Although testosterone therapy is being increasingly prescribed for men, there remain many questions and concerns about testosterone (T) and in particular, T therapy in women. A literature search was performed to elucidate the origin of, and scientific basis behind many of the concerns and assumptions about T and T therapy in women. This paper refutes 10 common myths and misconceptions, and provides evidence to support what is physiologically plausible and scientifically evident: T is the most abundant biologically active female hormone, T is essential for physical and mental health in women, T is not masculinizing, T does not cause hoarseness, T increases scalp hair growth, T is cardiac protective, parenteral T does not adversely affect the liver or increase clotting factors, T is mood stabilizing and does not increase aggression, T is breast protective, and the safety of T therapy in women is under research and being established.

Testosterone implants in women: pharmacological dosing for a physiologic effect.

Objectives: The objectives of this study were to determine therapeutic serum testosterone (T) levels/ranges and inter-individual variance in women treated with subcutaneous T implants.

Study Design: In study group 1, T levels were measured at two separate time intervals in pre- and post-menopausal women treated with subcutaneous T for symptoms of androgen deficiency: (i) four weeks after pellet insertion, and (ii) when symptoms of androgen deficiency returned. In a separate pharmacokinetic study (study group 2), 12 previously untreated postmenopausal women each received a 100mg T implant.

Testosterone pellet implants and migraine headaches: a pilot study.

The purpose of this prospective pilot study was to determine the therapeutic effect of continuous testosterone, delivered as a subcutaneous implant, on the severity of migraine headaches in pre- and post-menopausal patients. Twenty-seven women with a history of documented migraine headache were asked to rate their headache severity using a five-point scale at baseline (prior to therapy); and again, 3 months following treatment with testosterone implants. Improvement in headache severity was noted by 92% of patients and the mean level of improvement was statistically significant (3.

Improvement in scalp hair growth in androgen-deficient women treated with testosterone: a questionnaire study.

Background: Androgens are thought to have an adverse effect on female scalp hair growth. However, our clinical experience of androgen replacement therapy in women with androgen deficiency, in which hair loss was seldom reported, led us to question this concept.

Objectives: To evaluate the effect of subcutaneous testosterone therapy on scalp hair growth in female patients.

Beneficial effects of testosterone therapy in women measured by the validated Menopause Rating Scale (MRS).

Objectives: This study was designed to measure the beneficial effects of continuous testosterone therapy, delivered by subcutaneous implant, in the relief of somatic, psychological and urogenital symptoms in both pre- and post-menopausal patients, utilizing the validated Health Related Quality of Life (HRQOL), Menopause Rating Scale (MRS).

Study Design: 300 pre- and post-menopausal women with symptoms of relative androgen deficiency, were asked to self-administer the 11-item MRS, at baseline and 3 months after their first insertion of the subcutaneous testosterone implant. Baseline hormone measurements, menopausal status and BMI, were assessed to determine correlation with symptoms and clinical outcome.

Pilot study: absorption and efficacy of multiple hormones delivered in a single cream applied to the mucous membranes of the labia and vagina.

Background/aims: There is a lack of evidence in the literature supporting vaginal application of a combination hormone-containing cream for local and systemic symptom relief. This pilot study examined the extent of absorption of a single cream containing estriol, estradiol, progesterone, DHEA, and testosterone.

Methods: A combination cream was administered to 12 postmenopausal women in two differing doses over two independent time periods.
