How to increase semen volume may involve medications, such as testosterone therapy, imipramine, or pseudoephedrine. However, these should only be used under the guidance of a urologist, as the best treatment depends on the cause.
Low semen volume cannot always be treated with medication. In some cases, there may be a blockage in the duct that carries semen to the urethra, and surgery is usually needed. If you notice a change in the amount of semen you produce, it is important to find out what is causing it before starting treatment.
Some habits may help increase semen volume naturally, such as eating a healthy, balanced diet, exercising regularly, avoiding smoking, reducing alcohol intake, managing stress, and getting enough good-quality sleep.
If you are concerned about low semen volume, see a urologist for a proper diagnosis and personalized treatment.
