To determine if a connector is male or female look at the threads used on the connector. If the connector threads are on a housing that spins you have the male version of that connector.
Conversely, if the threads are not on a spinning housing but are instead on the outside of the connector than you have a female connector
NOTE: Most professionals assume that the connector tip is what determines male vs female. The connector tip determines the polarity of the connector.
