The question asks for the glands of the female reproductive system that are homologous to the prostate gland in males.
Step 1: Skene's glands are small exocrine glands located near the female urethra. They are considered homologous to the prostate gland in males due to their embryonic origin from the same tissue.
Step 2: Bartholin's glands are responsible for lubrication, not homologous to the prostate. Mammary glands are responsible for milk production and not homologous to the prostate. Bulbourethral glands are responsible for secreting pre-ejaculate fluid in males. Thus, the correct answer is option (1): Skene's glands.
