Men who have more daughters and no sons, may have a greater risk of getting prostate cancer, according to researchers//.
A team of Israeli researchers compared families of men diagnosed with prostate cancer with other men and found that having more daughters and risk of prostate cancer were related.
The Journal of the National Cancer Institute study agrees there may be a link but the factors responsible for prostate cancer and having more daughters may be the male "Y" sex chromosome, not the act of having either a son or daughter.
UK experts also said that a common genetic condition may cause both cancer risk and the chance of fathering girls.
Prostate cancer is the most common among male cancers, with a number of new cases being discovered every year.
As the name suggests, prostate cancer develops from cells of the prostate gland, found only in men producing some of the seminal fluid, which protects and nourishes sperm cells.
The Israeli researchers studied 38,000 men, and compared history of 712 men diagnosed with prostate cancer with other men and found that overall, compared with men who had at least one son, those with only daughters were 40% more likely to develop prostate cancer.
The risk appeared to increase when a man had three or more daughters and no sons as men with three daughters and no sons were up to 60% more prone to develop prostate cancer
The researchers looked for other explanations for the noticeable difference and came to a conclusion that, having more number of daughters might encourage a man to be more health-conscious and attend routine health check ups, which leads to detection of prostate problems.
Another possibility was that men with a desire to father a son, on having daughters continuously might go to the doctor to find out if there was any problem.
