(Spoiler warning) Yes, I very much believe so. A character jokes about a "male head" being used as a "stud" and how he "doesn't lead too bad a life" before he'll eventually be killed. Also, later in the book, characters joke about an individual whose penis is served for dinner.
(Spoiler warning) There are descriptions of situations where women harm themselves to induce a miscarriage. And while not self-harm, there is a scene where a character is described as having accidentally cut themselves.
(Spoiler warning) Yes, there is a description of an event where a someone "melts down" at work and is sent to a psychiatric facility. There is at least one other "meltdown", as well, described during the church scene.
(Spoiler warning) Yes, there is described event where a "head" was regularly "stored" alive in a wooden, coffin-like box, too small for them to move, hidden beneath someone's bed. They were found trapped inside the small space.
I would say yes. Blood is taken from pregnant women, causing them to miscarry. It is known that this will occur when the blood is taken, and it is against the will of the pregnant women.
