Magento - Get customer gender from order query - magento

Question

I have made a query that gets customer's orders. Can I get customer gender based on this query? If not, how can I get customer gender? This is the code I have so far:
<?php
require_once('app/Mage.php'); //Path to Magento
umask(0);
Mage::app();
$productId = 297;
$orders = Mage::getModel('sales/order')->getCollection();
$orders
->getSelect()
->joinLeft(
array(
'order_item' =>Mage::getSingleton('core/resource')->getTableName('sales/order_item')),
'order_item.order_id = main_table.entity_id',
array('product_id'=>'product_id'))
->where('product_id=?', $productId)
->group('main_table.entity_id')
->order('main_table.entity_id DESC');
$fields = "date,company,name,country,city,address,postcode,itemname,quantity,price,sku \n";
foreach($orders as $order):
$order->getData();
$order->getIncrementId();
$billingAddress = $order->getBillingAddress();
$shippingAddress = $order->getShippingAddress();
$billingStreet = $billingAddress->getStreet();
$countryCode = $billingAddress->getCountry();
$country = Mage::getModel('directory/country')->loadByCode($countryCode);
$fields .=
date('Y-m-d',strtotime($order->getCreatedAt())).','.
$billingAddress->getCompany().','.
$billingAddress->getName().','.
$country->getName().','.
$billingAddress->getCity().','.
$billingStreet[0].','.
$billingAddress->getPostcode().','.
$order->getShippingDescription() .',';
foreach ($order->getAllItems() as $itemId => $item):
$itemname = $item->getName();
$itemname = str_replace('&', " ", $itemname);
$fields .=
$itemname. ','.
$item->getQtyOrdered().','.
$item->getPrice().','.
$item->getSku().',';
endforeach;
$fields = rtrim($fields, ',');
$fields .= "\n";
endforeach;
$name = date('d-m-Y-H-i-s');
$output = fopen('backend/assets/csv/' . $name . '.csv', 'w');
fwrite ($output,$fields);
fclose ($output);

foreach($orders as $order){
$customer = $order->getCustomer();
Mage::log($customer->getGender());
}
if this does not work then:
foreach($orders as $order){
$customer = $order->getCustomer();
$customerObj = Mage::getModel('customer/customer')->load( $customer->getEntityId());
Mage::log($customerObj->getGender());
}
