    copied!<p>I suggest building a custom SQL query to pass to <code>$wpdb</code>, since complex taxonomy queries are notoriously harder to implement than their SQL equivalents.</p> <p><strong>Note</strong>: You can always <a href="http://codex.wordpress.org/Editing_wp-config.php#Save_queries_for_analysis" rel="nofollow">output the most recent SQL WordPress executed</a>. This is a very nice way to debug these kind of problems.</p> <p>Back to your question, this is what the final code snippet would look like:</p> <pre><code>$gender = 'unknown'; $taxonomy = array('male' =&gt; 'mens', 'female' =&gt; 'womens'); $where_clause = ''; if ( array_key_exists($gender, $taxonomy) ) { $where_clause = sprintf("WHERE %s = '%s'", "$wpdb-&gt;terms.slug", $taxonomy[$gender]); } $query = "SELECT $wpdb-&gt;posts.* FROM $wpdb-&gt;posts INNER JOIN $wpdb-&gt;term_relationships ON ($wpdb-&gt;posts.ID = $wpdb-&gt;term_relationships.object_id) INNER JOIN $wpdb-&gt;term_taxonomy ON ($wpdb-&gt;term_relationships.term_taxonomy_id = $wpdb-&gt;term_taxonomy.term_taxonomy_id) INNER JOIN $wpdb-&gt;terms ON ($wpdb-&gt;term_taxonomy.term_id = $wpdb-&gt;terms.term_id) $where_clause"; $posts = $wpdb-&gt;get_results($query); </code></pre> <p><strong>Update</strong>:</p> <p>If you prefer to use tax_query:</p> <pre><code>$gender = 'unknown'; // Build Gender Tax-Query if($gender == 'male') { $gender_query = array( 'relation' =&gt; 'AND', array( 'taxonomy' =&gt; 'category', 'field' =&gt; 'slug', 'terms' =&gt; 'mens', 'operator' =&gt; 'IN' ) ); } elseif($gender == 'female') { $gender_query = array( 'relation' =&gt; 'AND', array( 'taxonomy' =&gt; 'category', 'field' =&gt; 'slug', 'terms' =&gt; 'womens', 'operator' =&gt; 'IN' ) ); } else { $gender_query = array( 'relation' =&gt; 'AND', array( 'taxonomy' =&gt; 'category', 'field' =&gt; 'slug', 'terms' =&gt; array('mens', 'womens'), 'operator' =&gt; 'IN' ) ); } // Get posts $args = array( 'post_type' =&gt; 'post', 'post_status' =&gt; 'publish', 'posts_per_page' =&gt; 2, 'orderby' =&gt; 'rand', 'tax_query' =&gt; $gender_query ); $posts = get_posts($args); </code></pre> <p>The key to both answers is that you should not <em>exclude</em> items based on gender, but rather include (assuming the gender neutral items are properly categorized in <em>womens</em> and <em>mens</em>).</p>
