how hide empty category

Using Django

I have a hoodie category and two gender divisions male and female. How can I hide a category hoodie for a gender that does not have this product?
html:

{% get_genders as genders %}
                    {% for gender in genders %}
                <li>
                    <!-- First Tier Drop Down -->
                    <label for="drop-2" class="toggle">Категории <span class="fa fa-angle-down"
                                                                       aria-hidden="true"></span> </label>

                    <a href="/">{{ gender }} <span class="fa fa-angle-down" aria-hidden="true"></span></a>
                    <input type="checkbox" id="drop-2">

                    <ul>
                        {% get_category as categories %}
                        {% for category in categories %}
                        <li><a href="{%  url 'category' gender_slug=gender.slug category_slug=category.slug %}">{{category.name}}</a>
                        </li>
                        {% endfor %}
                    </ul>
                </li>
                {% endfor %}

I’m try make many to many field gender for category, but I don’t know how to write in html

models.py

class Gender(models.Model):
    name = models.CharField(max_length=100)
    slug = models.SlugField(max_length=200, unique=True)

    class Meta:
        verbose_name = 'Гендер'
        verbose_name_plural = 'Гендеры'

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('gender', kwargs={'gender_slug': self.slug})

class Category(models.Model):
    name = models.CharField(max_length=100)
    gender = models.ManyToManyField(Gender)
    slug = models.SlugField(max_length=200, unique=True)

    class Meta:
        verbose_name = 'Категория'
        verbose_name_plural = 'Категории'

    def __str__(self):
        return self.name
      
    def get_absolute_url(self):
        return reverse('category', kwargs={'category_slug': self.slug})

You don’t do that sort of work in the template or in your html.

It’s the responsibility of your view to pull the data together to be rendered by your template.
