There are some misconceptions in this thread about male infertility. Erectile dysfunction is a completely different thing than infertility. ED is the inability to complete the act successfully. Infertility is the absence of viable sperm. ** Men with ED may very well produce viable sperm and men with infertility may very well be able to "do it". ** I think that the majority of those who suffer infertility are unaware of the issue until pregnancy is attemped unsuccessfully. Then there are some who have a hint that it may be a problem - such as those who have PCOS. There are relatively very few who know for sure that they are infertile prior to marriage. Those who are aware of infertility for sure need to 'fess up before marriage.
Absolutely! There is difference between 'impotency' and 'infertility'.
