The head of your penis is your GLANS, your testicles are your GLANDS

That is all I know about anything!

This thread has some good info and drawings:

Penis Anatomy

Here are the major endocrine glands in a man:

Pineal gland
Pituitary gland
Thyroid gland
Thymus
Adrenal gland
Pancreas
Testes

Yep, that sounds about right.

I think “glans” comes from the Latin for “acorn”. “Gland” comes from that same word, but evolved as “glandula” and then came through French before becoming “gland” in English.
