Vestibular or Bartholin’s glands
Bartholin’s gland or greater vestibular glands are accessory sex glands in females. They are situated on either side of the vaginal orifice. These glands are homologous to the bulbourethral glands of the male. It secretes a viscid fluid that provides lubrication to the vestibular region during sexual intercourse.

Cowper’s glands
Bulbourethral glands or Cowper’s glands are paired glands located on either side of the proximal portion of the urethra. They secrete mucus which helps in the lubrication of the penis. Mucus also helps to neutralise remaining acidic urine in the urethra before the release of sperms.

Ampullary glands
Ampullary glands are paired glands associated with the male reproductive system of horses, dogs and ruminants. They are present at the terminal of vas deferens and secrete lipids and glycogen into the seminal fluid.

Vesicular glands
Seminal vesicles or vesicular glands are the paired glands located near the base of the bladder, above the Cowper’s glands. It produces alkaline secretions and contributes to $60\%$ of the semen.
