Експресія рецепторів статевих стероїдів в ектопованому ендометрії у жінок із різними формами ендометріозу
Estradiol and progesterone receptor expression in ectopic endometrium was significantly reduced in women with internal and external endometriosis compared to extragenital endometriosis, and decreased with distance from the uterus.

The paper investigated expression of estradiol and progesterone receptors (antigens) in heterotopic/ectopic endometrium from uterine tissue in 35 women with internal endometriosis, 52 with external endometriosis, and 19 with extragenital endometriosis after resection of lesions. Histological examination of extirpated uterus was used to compare prevalence and intensity of steroid receptor expression across lesion localization and distance from the uterus. Estradiol and progesterone receptor expression was significantly reduced in the internal and external groups compared with the extragenital group, and receptor expression intensity decreased with increasing distance of lesions from the uterus. The paper’s limitation is that it is based on tissue from these surgical populations and does not address other molecular or hormonal factors beyond receptor expression. This paper is centrally about endometriosis — it quantifies how estradiol and progesterone receptor expression in ectopic endometrium varies across different forms of endometriosis and lesion distance from the uterus.
