Use of Assisted Reproduction Techniques Linked to Increased Prostate Cancer Risk, Study Suggests
Men who father children through assisted reproduction techniques, either in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), may be at a higher risk of developing prostate cancer, a study shows. Early screening for prostate cancer may also be beneficial for infertile men, according to the study, titled "Risk of prostate cancer for men fathering through assisted reproduction: nationwide population based register study" and published in The BMJ. Both prostate cancer and male infertility are associated with androgens — the so-called male hormones — suggesting a link between the two conditions. However, previous studies reported conflicting results about whether infertility increases, decreases, or has no effect on prostate cancer risk. This may be partly due to limited data used in these studies: "Previous studies have often had small cohorts, short follow-up times and some have been based on self-reported diagnoses," Yvonne Lundberg Giwercman, a professor at Lund University in Sweden and co-author of the study, said in a press release.
