wouldn't Natural selection eliminate sexual dysfunction early on, since its such a critical step in genetic prorogation, even if it remain recessive? For many a men, it's not simply a mental inhibition, but a biological reinforcement.

Many men suffer from them this, but most of it come from the decline in hormones as they age. Most the time when this happens this is past a males sexual prime/the age they have kids. Males peak from about 18 to early 20s but even though we might have kids later we still haven't reached the age where everything starts to decline. This way the genes that might control this are gone and are already in the next generation. Now it is getting harder to figure this out because many more things are leading to sexual impotence, such as prostate cancer and things in that nature. So even though we might not be passing down a gene that turns it on and off we are still passing down genes that can indirectly affect our sexuality in that way.

impotence still happens, but not always is it genetic thing. Of course genetics and biology play a big part, but it is also brought on by accidents, illness or medications. So it is not just a mental issue either. Many things can cause it, and Medical Science has found ways to by pass those issues and therefore that is why is has continued to happen. There have been many things that were not to be able to reproduce, but some how through the natural selection process, they found a way to over come it

The same question holds for all the invalidating defects, such as shortsightedness.
Evolution does not ensure a path to perfection.
Only the successful ones can transmit their genes to the next generation but still many recessive defects may reappear because many transmitted genes are not frequently activated.
Even negative features are transmitted, such as huge disproportionate beaks, simply because of female preference when mating.

Hi. Any species that could not replicate would indeed have lost out in the evolutionary cycle. Unfortunately (or fortunately) this only happens to next generation groups. Those which did not reproduce are not here to testify.
