The fact is Henry's male heir that he did have died young and it was his daughters that ruled the nation. His first daughter Mary died from a horrible disease likely stomach cancer. Her younger sister hated her father sooooo much that in fact she never wanted his personal bloodline to rule after her. Its why queen Elizabeth stayed single and had James her cousin appointed as king upon her death. So in fact it was Henry's elder sister that the bloodline go thru. This was Elizabeth's last comeuppance over her own father basically rubbing his nose in the sh*t if you will to will regarding his male heir and his male blood. Saying you were so all about having a male heir well I will make sure its your sisters blood to sit on that throne and not you father.
yeah I realized after I hit enter that it was really that he wasn't able to have male children... none that could not survive that is due mainly to an inbred blood disease that ran amongst Europe's royals, but even the female children were not that many (considering how much he f'd around) and not all that healthy. But the main reason Elizabeth didn't have children is that she didn't want to marry and have a husband "rule her" becoming king and ruler and her having to take the "consort" spot. The ending the legacy was the cherry on top.
Bottom line is the failure of siring heirs and specifically male heirs was with him, but the wives were the ones that were getting tossed out or beheaded.

Why does she assume she’s infertile because she and the ugly ass traitor could not get pregnant? Like there wasn’t even a sub-plot point if she does or doesn’t get her period, it’s just oh I couldn’t have a baby with this guy so I can’t have a baby at all.
Like it takes two to make a baby, that’s a good chance that warthog-looking thing was the one whose sperm count was in the negatives.

Like I find it so funny that I know she gets pregnant and it’s foretold that she had more children by the ML’s sister but absolutely no one thinks twice when she says she can’t get pregnant. Like call a doctor?
