Testosterone deficiency syndrome.
What does testosterone do?
Testosterone is the primary androgen. It promotes the development of male qualities and also is vital for sperm manufacturing (spermatogenesis). Degrees of testosterone are normally a lot higher in individuals designated AMAB than in people designated woman at birth (AFAB).

How typical is low testosterone? Testicular Hypogonadism
It’s tough for scientists to approximate exactly how typical low testosterone is because various research studies have various definitions for low testosterone.
Information suggest that regarding 2% of people AMAB might have low testosterone. And other studies have actually estimated that more than 8% of individuals AMAB aged 50 to 79 years have low testosterone.
What are the symptoms of low testosterone?
Symptoms of low testosterone can differ considerably, specifically by age.
Symptoms that highly suggest low testosterone in grownups designated man at birth include:
