Endometrium with changes due to exogenous hormones is relatively common in endometrial samples.
Endometrial changes of oral contraception, oral contraceptive effect, OCP endometrium, and endometrium with hormonal changes redirect here.
The oral contraceptive pill is dealt with in the article oral contraceptive pill.
General
- Very common.
- Most pills a mix of progesterone and estrogen.
- The progesterone is what generates the characteristic appearance -- that is similar to pregnancy.
- Same appearance is seen with a levonorgestrel-releasing intrauterine device, e.g. Mirena.
Microscopic
Features:[1]
- Inactive glands (round/ovoid glands, simple cuboidal epithelium, no mitoses).
- Stroma decidualized -- mnemonic NEW:
- Nucleus central.
- Eosinophilic cytoplasm.
- Well-defined cell borders.
DDx:
- Endometrial hyperplasia with secretory changes - proliferative activity.
- Secretory phase endometrium - glandular changes of the secretory phase (cytoplasmic vacuolization), secretions in the glands.

Micro
The sections show endometrium with nonproliferative endometrial glands and stromal decidualization. The gland-to-stroma ratio is within normal limits.
