This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.

The cones are sexually dimorphic: the male cone is a 40 to 50 cm long cylinder that is 7 to 10 cm wide with a peduncle that is up to 2 to 3 cm long; the female cone is 25 to 50 cm long, 20 to 25 cm wide, and sessile. Males can have up to ten cones at one time and females can have up to five cones at one time. [3]
