Infertility increases a man's risk of prostate cancer

22.03.2010
Infertile men have an increased risk of developing high grade prostate cancer, which is more likely to grow and spread quickly.

That is the conclusion of a new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society. The study's results suggest that because infertility may be an identifiable risk factor for prostate cancer, early screening may be warranted in infertile men.

Research focusing on the number of children a man has have pointed to male fertility's potential associated with risk for prostate cancer. However, studies on the topic have generated conflicting results: some have found that men with children had a higher risk than childless men; some have found that men with fewer children had a higher risk than men with more children; still others failed to identify any association between the number of children fathered and a man's risk for prostate cancer.

Because the number of children a man has may not accurately reflect his ability to cause a pregnancy, Thomas Walsh, MD, MS, of the University of Washington in Seattle and his colleagues designed a more accurate study to evaluate the association between male infertility and prostate cancer. They studied the risk for prostate cancer in a group of 22,562 men evaluated for infertility from 1967 to 1998 in 15 California infertility centers. The incidence of prostate cancer in these men was compared with the incidence in a sample of men in the general population who were of similar ages and from similar geographic locations.

The researchers identified 168 cases of prostate cancer that developed in men who were evaluated for infertility. That number not significantly different from the expected rate (185 cases), suggesting that overall, men evaluated for infertility were not at a higher risk of being diagnosed with any type of prostate cancer compared with men in the general population. However, men who were evaluated and found to be infertile were 2.6 times more likely to be diagnosed with high grade prostate cancer than men who were evaluated but were found not to be infertile.

The authors say if these results are confirmed in other studies, it may be appropriate for infertile men to be considered for early prostate cancer screening, given their elevated risk for aggressive disease. They add that the results should stimulate research on possible common biological pathways underlying infertility and prostate cancer.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
