During the process of oogenesis, primary oocytes produce ____.

Oogenesis is the process that gives rise to the ovum, or egg, in mammals. The oocyte is the immature egg cell in the ovary. In humans, one oocyte matures during each menstrual cycle. It develops first into an intermediate form called the ootid, and eventually into an ovum. The prefix oo- is derived from Greek, and means “egg.”
