Does being co-codamol affect your sperm.my partner been on them near 2 years. we have been trying for a baby since christmas with no success?

Maybe (not) . . .: Co-codamol is a brand of codeine+paracetamol sold in the UK to control pain. Chronic narcotic use can affect pituitary function resulting in decrease signal to testes, so less testosterone & possibly less sperm. But codeine is not considered a particularly powerful narcotic, although it may have some effect on pituitary. Best to have semen analysis. BTW, it can take up to 1yr to get pregnant.
