Abstract

We aimed to investigate the effect of metal ions on the semen of males of child fathering age with metal-on-metal (MM) total hip arthroplasty (THA). Semen was collected form 11 patients with MM THA and 5 control of comparable age. Cobalt and chromiun concentrations were measured in both the seminal plasma and in the blood of patients. Results showed that cobalt level was higher in the seminal plasma of MM THA patients (2.89 μg/L) compared to control patients (1.12 μg/L) (P = .011). The ejaculate volume, the sperm density, the total sperm count, the pH, and the percentage of cells with normal morphology were in the range of the World Health Organization criteria for fertile population.

    Can a child whose father had high cobalt levels in their sperm (due to hip implant) be affected by this in any way? Are there any studies on this?

    1. I printed this study because I have never seen any work done on this before. The group that did the work is a very reputable group.

      The short answer is I don't know. If you have some concerns, I would suppose you could just phone one of the study authors. I'm sure they would answer your qeuestions.
