如何使用javascript和php启用或禁用组合框内的值

Question

I want to enable/disable value inside <select> tag based on value from PHP.

The variable is $gender.

If $gender = female then value(Menstruasi) = enabled

else if $gender = male then value(Menstruasi) = disabled

Here is the code :

<select name = "keterangan_cuti_khusus">
<option value="" selected> - = - </option>
<option value="Insidental">Insidental</option>
<option value="Pengembangan_skill">Pengembangan Skill</option>
<option value="Ibadah_Haji">Ibadah Haji</option>
<option value="Masa_kerja">Masa Kerja</option>
<option value="Melahirkan">Melahirkan</option>
<option value="mensturasi">Mensturasi</option>  
</select>

I want

<option value="mensturasi">Mensturasi</option>  <--- disable/enable -->

change where gender is female or male.

Is there any ideas ?
