Curious if in vitro fertilization (IVF) could consider RNA impact when evaluating fitness.

Current criteria appear to be motility, morphology, and DNA attributes (fragmentation & integrity) [1], all mostly visual or physical assessments.

I see you being downvoted, but it's a good quip.

Lamarckian vs. Mendelian genetics was about heritable traits being acquired in life (Lamarck), or being discrete units passed down at conception (Mendel).

Genetics is almost entirely Mendelian, but some of epigenetics is durable and thus Lamarckian.

There's also retroviral integrations, transposons, and all sorts of other complexities that don't fit neatly into boxes.

assuming this is true, perhaps it's best to freeze sperm regularly with labels that way if you go off the deep end you can snapshot quite literally your best self? some possible times - right before college, right after college, after you meet someone you think you'd marry (but before you do), after marriage.

seems like a neat premise for a sci fi novella.

I would recommend keeping tabs on authors rather than periodically checking specific publications.
