Hypospermia is defined as a decrease in ejaculate volume below 2.5 ml. According to the World Health Organization (WHO), the regular volume of normal semen ejaculated by a healthy man should be between 1.5 and 6 ml of the total ejaculated fluid.
Treatment is based primarily on the specific cause that is causing the hypospermia, so it is essential to first find the cause. It may require restorative surgery, lifestyle changes or a change in medication.
