There is not much research in the way of this but since there is evidence estrogen damages serotoli and leydigg cells, and turning your balls off for years obviously warrants concern for everything concerning them, there is a chance of DNA fragmentation and lower than normal standard morphology of the sperm.
It's definitely been observed as in that study that trannies who can make sperm shortly after quitting HRT have low motility (sperm no go far), volume, sperm count, and lower amounts of normal shaped sperm.
There is no data comparing people pre HRT with normal sperm count, morphology and so on, to the same people after years of HRT and years of cessation to see how their sperm quality compares.
So we don't KNOW but there's obvious reason to assume nuking your balls for years may fuck up your cum and increase chances of impacting the baby.
I'm very curious to know the health quality of these kids born to these trannies. It's noteworthy that they were able to pull it off without even using HGC or clomid. I didn't see the age mentioned in the study but a plebbit poster said one of them was on HRT for 18 years and still had a kid. Just be cautious because it may or may not mean there's a chance of increasing the likelihood of them being retarded or something since estrogen directly damages the baby factory in your sack.
This is important for hrt femboys who are concerned about fertility mostly since most mtfs here never care about this but some detrans and seek this info. Maybe there's more info on morphology post HRT and whether or not the normal shaped sperm are in line with the average (4%) but I haven't seen any yet
