The Court of Arbitration for Sport will hold a landmark hearing this week regarding Olympic athlete Caster Semenya's case against the world's athletics governing body's stance on her sexuality. <br />The International Association of Athletics Federations had proposed forcing athletes with different levels of sexual development to medically lower their testosterone levels for fairer competition. <br />The South African 800-meter star would be affected by such rules and has challenged the plan, saying it goes against gender equality. <br />The proposed rules were scheduled to take effect last November, but have been put on hold pending the week-long hearing which begins Monday.<br />The ruling is expected to come out near the end of next month. <br />
