<?php
if (isset($_POST['submit'])) {
     if (!isset($_POST['gender']) || empty($_POST['gender'])) die("Please select a gender");
     else echo "You are a " . $_POST['gender'];
}
?>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
     <label for="genderMale"><input type="radio" id="genderMale" value="male" name="gender" /> Male</label>
     <label for="genderFemale"><input type="radio" id="genderFemale" value="female" name="gender" /> Female</label>
     <input type="submit" name="submit" value="Submit Gender" />
</form>

 

If this was a problem, one could just set a selected value to one of the radio buttons checked="checked" i do believe.
