anastrozole and Hypogonadism

anastrozole has been researched along with Hypogonadism in 13 studies

Hypogonadism: Condition resulting from deficient gonadal functions, such as GAMETOGENESIS and the production of GONADAL STEROID HORMONES. It is characterized by delay in GROWTH, germ cell maturation, and development of secondary sex characteristics. Hypogonadism can be due to a deficiency of GONADOTROPINS (hypogonadotropic hypogonadism) or due to primary gonadal failure (hypergonadotropic hypogonadism).

Changes in Energy, Mood and Anxiety Scores for Subjects Taking Anastrozole (T-A) and for Subjects Taking Placebo (T-P).

Changes in energy, mood and anxiety scores were measured using The Beck Depression Inventory II and the POMS questionnaire. The Beck Depression Inventory II questionnaire consisted of 21 questions, each with answers ranging from 0-3. The answers for each question were summed. The scale ranged from 0-63 with higher scores meaning a higher depression score (worse score). The POMS questionnaire had a total of 65 questions that measured tension, depression, anger, vigor, fatigue and confusion. The total POMS score ranged from 0-200, with lower scores being better. The POMS tension score ranged from 0-36 with lower scores being better. The POMS depression score ranged from 0-60 with lower scores being better. The POMS anger score ranged from 0-48, lower scores being better. The POMS vigor score ranged from 0-32, lower scores being better. The POMS fatigue score ranged from 0-28, lower scores being better. The POMS confusion score ranged from 0-28 with lower scores being better. (NCT00179517)

Sexual Function Scores, Calculated Using S-Score and Reynolds' Sexual Questionnaires, Will Increase More Anastrozole and Testosterone Treatment Than With Placebo and Testosterone Treatment.

S-Scores and Reynolds Questionnaire scores were assessed at baseline and once a month over three months. The average change in score for each questionnaire over the 3 month study was reported. The S-Scores questionnaire measured sexual function and consisted of four questions with five possible answers. The total scale range was 0-20, with higher scores were considered better. S-Scores that were greater than or equal to 16/20 were considered normalized S-Scores. Reynolds Questionnaire is a 21 item survey that monitors sexual interest, activity, satisfaction, and function. The scale for the Reynolds questionnaire for sexual interest was from 0-12, with higher scores being better. The scale for sexual activity was 0-41 with higher scores being better. The sexual satisfaction scale was from 0-21 with higher scores being better. The scale for sexual function was from 0 to -12 with lower scores being better. (NCT00179517)

The Proportion of Men Who Achieve Normalization of Sexual Scores (Sexual Interest Function,) Using Anastrozole and Placebo

The proportion of men who achieve normalization of sexual scores (scores greater than or equal to 16/20) on anastrozole (T-A) and those on placebo (T-P) are reported. Both Men who achieve normalization of sexual scores and those who did not achieve normalization of sexual scores were reported for anastrozole (T-A) treatment group and the placebo treatment group. Sexual scores were gathered once per month for three months with the average of the three months reported. (NCT00179517)
