At what stage in the relationship should a guy tell the lady he loves and plans to marry that he wont be able to father a child due to a medical condition, despite not being impotent. Early in the affair? Later in the affair but before he proposes? When he's proposing? After the proposal but before the wedding? After the wedding? Or never till she finds out? Pls your honest views.

Thanks y'all for your comments! They'll really be of help.
@lady T, it's not zero sperm count, it is low plus other sperm anomalies!
@nekai, yes i agree wt u. Stuffs like this are not usually discovered until after marriage, cos people rarely set out to check if they have any hidden sperm abnormalities. But the guy in question is a frnd who happens to have some subtle features suggestive of a certain condition that presents with infertility. And tests have comfirmed it. Now his conscience would not let him marry his love without letting her know. So that's how he managed to know, otherwise he would most likely discover after years of childlessless in marriage (of course after the initial stage of blamìng the wife)
Pls more comments are welcome.
