uterine

A few inaccuracies in your comment: Estrogen will induce breast and uterine cancers unless it is given with progesterone.

For instance a family friend was told she had uterine cancer and was all set to start her doctor's protocol.

Menstruation, when it happens, forcefully cleans out implanted zygotes, returning the uterine hormonal balance to normal.

Outside of pregnancy, these arteries are tiny, twisty things spiralling through depths of the uterine wall.

There's also a link between post-menopausal hormone replacement therapy (older women taking estrogen after their body ceases production) and breast/uterine cancer.

Sure there is: chemical exposure balance or random variation in the uterine or infant environment.

Would it be possible to fake 70 cases of thyroid polyps, leukemia, testicular cancer and uterine bleeding so bad it requires transfusions?

She'd had several c-sections before (which she felt may have been unnecessary), which is why she was at risk of uterine rupture.

In her books, humanity invented two critical things: wormhole FTL travel and uterine replicators.

Agreed, but IUDs by definition are implanted into the uterine wall, manually.

If we had uterine replicators, the problem we're discussing would be a non-issue.

It didn't work, so he decided the problem must be uterine polyps and scheduled a dilation and curettage - essentially scraping out the inside of the uterus.

Sure, frozen embryos, frozen sperm and something like the "uterine replicator" from the Vorkosigan Saga (Bujold) [1] may allow this to happen.

You're asserting that my life would suddenly become meaningful again if we had "uterine replicators"?

"a relationship between two people categorically incapable of producing children together biologically, [the female of whom has had a hysterectomy following uterine cancer], can’t be a marriage."

"You're asserting that my life would suddenly become meaningful again if we had "uterine replicators"?" Yes, because now you (or I) have choice to procreate.
