Your radio inputs should all have the same name attribute and value should be the value of that input. For example

male <input type="radio" name="gender" value="MALE" id="male">
female <input type="radio" name="gender" value="FEMALE" id="female">
others <input type="radio" name="gender" value="OTHERS" id="others">

Now you can just simply get what is selected with

document.querySelector('input[name="gender"]:checked').value; //this will return MALE|FEMALE|OTHERS based on what is selected

You can also add required to any or all of your radio buttons html to ensure that user has to select something. Alternative you can pre-select one of the checkboxes with checked to make sure gender is always popilated

For more detail and celerity why should all have same name and different values

The radio group must have share the same name (the value of the name attribute) to be treated as a group. Once the radio group is created, selecting any radio button in that group automatically deselects any other selected radio button in the same group. You can have as many radio groups on a page as you want, as long as each group has its own name.

The value attribute defines the unique value associated with each radio button. The value is not shown to the user, but is the value that is sent to the server on "submit" to identify which radio button that was selected.

If you are using radio type, they should all have the same name.

And you spelled "female" wrong.
