during ovulation is only one ovary releases an egg or both of them can release

Answer 1

During ovulation, it is possible for both ovaries to release an egg, but typically only one ovary releases an egg each cycle. This is known as unilateral ovulation. However, in some cases of multiple ovulation, both ovaries release an egg simultaneously or within a short time frame. Twin pregnancies can result from the fertilization of two eggs released by each ovary during the same menstrual cycle.
