Which of the following female structures is homologous with the prostate gland in males?

A) the pineal gland
B) the Bartholin's glands
C) the para-urethral glands
D) the Cowper's glands

The para-urethral glands, also known as the Skene's glands, are homologous to the prostate gland in males. Both glands produce prostate-specific antigen (PSA) and have similar embryological origins. The Bartholin's glands produce lubricating fluid during sexual arousal in females, while Cowper's glands produce pre-ejaculatory fluid in males. The pineal gland produces melatonin and is not homologous to the prostate gland.
