Egg and sperm contribute equally to the successful development of the embryo. Nuclear vacuoles in the sperm head are associated with reduced natural fertility in men. Questions arise about what causes the nuclear vacuolization. Do we, as biologists, even promote the development of vacuoles in the laboratory without knowing?
