There is some evidence that, for men, it is good to empty the prostate gland now and then to help prevent prostate cancer, and you do that when you ejaculate. This was shown in a study that followed 32,000 men for 18 years. The group of men who ejaculated frequently over the years had markedly fewer cases of prostate cancer. And sperm quality also improves if you ejaculate now and then,” says Astrid Ditte Højgaard.
So men’s health can depend directly on ejaculation, but the massage has value for women too:
In terms of quality of life, it is enormously important to have orgasms,” says Astrid Ditte Højgaard, chief consultant at Aalborg University Hospital and clinical associate professor at the Sexology Clinic at Aalborg University.
