He may or may not go through the trouble.My immediate answer would be no Dave however if you google prostaglandins and inflammation they are responsible for producing inflammation and initiating the response for healing so you never know if somehow it initiated some inflammation in the nuts and resulted in some temporary infertility but I have never heard of this happening but then I haven't heard of anyone injecting a bull except your friend. Let us know how your friend gets on.

It will change his brand of beer to bud lightWill Estrumate or Lutalyse sterilize a bull……..
Super Sperm!I was pretty sure that no significant effects would be associated with a shot of Lutalyse or Estrumate (synthetic analogs of Prostaglandin F2-alpha) to a bull, but I was wrong... I found this:
"Administration of PGF2α (2.5 mg) before semen collection has been shown to increase semen volume and total sperm number."
