While "androgen" is a broad term, the most well-known and significant androgen is testosterone.
Here's a breakdown:
* Androgen: A general term for a group of hormones that promote masculine characteristics.
* Testosterone: The primary male sex hormone, responsible for developing and maintaining male characteristics like muscle mass, body hair, and a deep voice.
Other androgens produced by the testes include:
* Dihydrotestosterone (DHT): A potent androgen responsible for prostate growth and male pattern baldness.
* Androstenedione: A precursor to testosterone that can be converted into testosterone in the body.
So, while "androgen" is the most technically accurate term, "testosterone" is often used more colloquially to refer to the hormones secreted by the testes.
