Despite the importance of prostate cancer, its causes are unknown. Scientists know that genetics plays a robust role, and so they have strong evidence that food regimen and other lifestyle aspects are necessary as well.
The Harvard Ejaculation Study
The Health Professionals Follow-up Study has been collecting data on a big group of volunteers since 1986. All men are health care providers, including dentists, pharmacists, veterinarians, optometrists, ophthalmologists and podiatrists. Most are white. In 1992, 29,342 men aged 46 to 81 years provided information on the typical variety of ejaculations per thirty days in youth (ages 20–29), middle age (40–49), and up to date years. Ejaculation included intercourse, nocturnal ejaculation, and masturbation. Volunteers provided comprehensive health and lifestyle data every two years until the top of the study in 2000.
Scientists found no evidence that frequent ejaculation indicates an increased risk of prostate cancer. In fact, the reverse was true: high ejaculation frequency was related to reduced risk. Compared to men who reported 4-7 ejaculations per thirty days of their lifetime, men who ejaculated 21 or more times per thirty days had a 31% lower risk of prostate cancer. And even after taking into consideration other lifestyle aspects and the frequency of PSA testing, the outcomes held as much as rigorous statistical evaluation.

A chunk of the puzzle
The studies from the United States and Australia do little to reply these necessary questions—but they open a brand new avenue for research. Because each report that a high frequency of early ejaculation in adolescence has the best impact on prostate cancer risk many years later, they call attention to the role of events in adolescence, when the prostate is developing and maturing. Is. There is actually an example of a protracted lag between cause and effect. For example, childhood sunburn is a significant risk factor for malignant melanoma in maturity, and prenatal aspects that affect birth weight affect lifetime risk for hypertension and heart disease. appear.
“The child is the father of the man,” wrote William Wordsworth in 1807. Regarding prostate cancer, nevertheless, sexual intercourse in maturity could also be a predictor of risk in maturity.
