Choose the odd one out with respect to female reproductive organs:
Bulbourethral glands are accessory reproductive glands in males. They are found on the lateral side of the urethra and secrete a transparent jelly like fluid.
Ovaries are the primary female reproductive organs that produce ova and hormones.
Fallopian tubes are accessory ducts in females.
The external genital organs of the female are collectively known as the vulva. The vulva includes mons pubis, labia majora, labia minora, hymen and clitoris.
Hence the odd one out is bulbourethral gland.
