Question: "Are angels male or female?"
Answer: The Bible does not necessarily support the gender of angels being male or female. Whenever gender is specifically “assigned” to an angel in Scripture, it is male (Genesis 19:10-12; Revelation 7:2; 8:3; 10:7). However, this does not necessarily indicate that angels are male. Matthew 22:30 seems to indicate that angels are “sexless,” without gender: “At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven.” If angels do not procreate, there is no need for gender, at least not in the sense of human gender distinctions.
In a similar manner, God always refers to Himself in masculine language, although God is neither male nor female. He just uses masculine language because it more adequately describes who He is and what He does, especially in the patriarchal cultures in which the Bible was written. If angels do have a gender, in some form, Scripture would indicate that they are predominately or universally male. It is more likely that angels are genderless, just as God is, and that masculine language is just used to describe them and their role in serving God.
