Depends on how they reproduce and physique a bit.

The creator confirmed Frieza only apparently has one parent in canon so that would mean they reproduce asexually. If every alien looks the same then generally the audience doesn't know what gender.

Provided they are implied or stated to reproduce like normal and the series doesn't indicate their are more than two genders or something it will be clear enough. Though not an alien Bill Cipher indicated on his Reddit page run by the creators that his race had over a billion different genders with him admitting it takes paperwork which he hasn't cared to keep track of so by default genderless.
