Two small glands that open into the URETHRA just below the bladder in the male, and secrete a clear lubricant fluid that facilitates sexual intercourse. Also known as COWPER'S GLANDS.

For the electron-microscopic study, the bulbo-urethral glands were sliced into 1 mm pieces and were fixed in fresh ice-cold 3 % glutaraldehyde for 3 h and then 4 h in 0.1 M cacodylate buffer and then post fixed for 1-2 h in 1 % 0.067 M cacodylate-buffered osmium tetroxide.
