Male Menopause – Andropause

Treating the aging male means understanding the symptomology of male menopause. Declines of androgens and related factors must be considered since they affect physical and emotional health. Studies show that merely bolstering testosterone is not necessarily the sole or a simple solution. Review current research and medical articles on male menopause to create a viable protocol for your patients.

Suppression of Testosterone Does Not Blunt mRNA Expression of MyoD, Myogenin, IGF, Myostatin or Androgen Receptor Post Strength Training in Humans.pdf

This study concluded that despite blocked acute responses of testosterone and 10- to 20-fold lower resting levels in the goserelin group, ST resulted in a similar mRNA expression of myoD, myogenin, IGF-IE(abc), myostatin and androgen receptor as observed in the placebo group. Therefore, in the present study, the molecular events were the same, despite divergent muscle hypertrophy and strength gains.

Prevalence of Hypogonadism in Males Aged at Least 45 Years: The HIM study.pdf
