The Womb is the fourth environment of the game. The player will enter it after killing Mom, but only after they have beaten her once before. It is possible to access the Womb before even killing Mom once, by digging down from Depths II using the We Need To Go Deeper! item. The enemies in this environment are mainly worms and other medical things, and their behaviour often involves disappearing and reappearing across the room (e.g. with the Baby's teleporting or the burrowing behaviour of Para-Bites, Lumps and Fred)
From the chapter The Womb/Utero and onwards, all damage done to Isaac is set to 1 Heart (). Any type of damage that does 1 heart of damage by default (e.g Bombs) will still do 1 heart of damage in The Womb/Utero and onwards. The only way to avoid it is to use The Wafer item, which sets every type of damage to 1/2 Heart ().

- 1: The room will always appear once in this floor
- 2: The room will always appear twice in this floor
- Possible: There is a chance for this room to appear, usually due to certain criteria being met

Differences from previous floors
- Blood donation machines take away a whole heart instead of half. They can still be used twice for one heart by quickly using them again during Isaac's invincibility period after taking damage. This can be done because taking a full heart of damage gives Isaac a longer invincibility period.
- Two of Seven Deadly Sins can be encountered in one room multiple times.
