🧵 How badly does a man's sperm quality go down with age?

How true is this? Some anon said there was a /sci/ thread here about this but I can't find it in the archive

Mutations aren't a proxy for quality. Fertility is. This board is /pol/ tier retarded.

One thing is sperm quality, another quality of offspring.

I became a father at 29, I'm pretty sad about it

genes arent mapped on a ML model scale with features

there are too many confounding variables retard

>Mutations aren't a proxy for quality. Fertility is
Depends on what you mean by quality.
If high relative generational fertility is a sign of quality offspring (which would make sense according to ev. biology). Yet, biology strives, for a given environment, to relative perfection since less fertile variants are selected against and die out. Mutations are more likely to be detrimental to that relative peak of high fertility performance.

>quality of offspring.
Too subjective a nation.

>How true is this?
How true do you want it to be? Most de novo mutations lead to inactivation of a genes. Genetic function can still be taken over by functioning genes inherited from the mother's side which are less likely to succumb to disruptive de novo mutations. However, de novo mutations could potentially lead to problems in grand-children where the recombination of genetic material allows for a person to inherit two male variants (or genes).

>50% more
so basically none still?

Wait, just realized the twittertard literally doesn't know how to read a graph or doesn't know how percentages work

Have you got nonpermachemed exemplars in reading of de nueovo thing? I think that dropping genes is caused by eating poision.

Random added mutations are near guaranteed to be dysfunctional

I suppose there's degree of freedom in that randomness, but as far as I remember, if you print a slight set of few hundreds of mutations of virus, it's going to be lethal, even thou.

Lethality is bad for virus proliferation. Kinda proves my point.

Mutations aren't random though. We know that there are a large number of mutations that can only occur in the presence of other mutations

Yes, but I said it still going to be lethal, not that another mutations doesn't causes it's proliferation.

Genetic fitness is measured in proliferation in a given environment. ”Lethality” is something you value because you think it fits viruses.

Well, for virus to work, it needs to reproduce, and somehow it happens it consumes a cell to do that.

You may have valid point, but when it comes to proliferation of human spermat, it doesn't necessarily bring quality.

Then why does storm only have the power to control the weather and wolverine has both claws and regeneration?

Yes but we’re talking about genetic fitness and not what you find to be ”quality”.

Quality of virus is that it kills.

Sure. We’re talking about genetic fitness though.

I mainly wanted to state, that proliferation of organism isn't necessarily quality.

That is a feature, not a bug. Only a woman would be so stupid to believe there is a problem with increased mutations in males. A single successful man can impregnate thousands of females, therefore all other failed mutants are irrelevant.

This is all about mutations in the Y chromosome. Females don't have that chromosome.
