As well as developing the disease, experts believe that men who have problems with fertility get the cancer earlier in life, so should be screened at a younger age.
The new study compared the risk and severity of prostate cancer between men who needed fertility treatment and those men who conceived naturally.
Data from 1,181,490 children born alive in Sweden from 1994 to 2014, to the same number of fathers, was analysed for the study.
From the group, 20,618 men fathered a child through IVF (1.7%), 14,882 through intra-cytoplasmic sperm injection (ICSI, where the sperm is injected directly into the egg, 1.3%), and 1,145,990 through natural conception (97%).
Overall, after prior diagnosis of prostate cancer was taken into account, 0.37% in the IVF group, 0.36% in the ICSI group and 0.28% in the natural conception group developed prostate cancer.
The results showed that men needing ICSI had a 64% higher risk of prostate cancer, while those having IVF had a 33% increased risk.
