This week we will discuss various types of eunuchs and if they have the  ability to do Chalitza or Yibum. We will also learn about the  Hermaphrodite and the Tumtum and if they can do Chalitza and if their  spouses can eat Teruma. The ninth chapter discusses different  relationships where the wife can be forbidden or permitted to marry the  husband, but can also be prohibited or permitted to his brother, the  Yavam.
