It might come as a surprise, but men go through a similar midlife shift known as andropause—often referred to as “male menopause.” While less talked about, andropause is just as real and just as impactful.

Findings are clear: the gradual drop in hormones like testosterone plays a major role in many of the issues men face in their 40s, 50s, and beyond. What Exactly is Andropause? As men...

Testosterone, whether endogenous or given exogenously, negatively feeds back on the hypothalamus, limiting GnRH and thus LH and FSH from the pituitary. A man taking supraphysiological doses of testosterone can expect to have very low or undetectable levels of LH and FSH in the serum. What happens when the...
