Last minute At home insemination

Sooo... after a ton of sex leading up to ovulation, my hubby couldn’t maintain a strong enough erection for sex and to finish via sex on O day. He ended up ejaculating via masterbation instead and we were just going to get it it up digitally, but then we realized we have a ton of medicine syringes from Tylenol packs etc... we THOUGHT we grabbed an unused one and then realized it might have been used. Could the sperm mixing with trace amounts of Tylenol cause any issues should I conceive?
