The occurrence of hemangioma in the female genital tract, particularly in uterine cervix, is rare. The majority of them show asymptomatic behavior. Surgical excision remains curative in most of the cases. Conservative therapies such as sclerosing agents, cryotherapy, and CO(2) laser excision may be alternatively applied. We present three cases of hemangiomas of the cervix in asymptomatic women, diagnosed as cavernous hemangioma in two cases and capillary hemangioma in one. All tumors were immunoreactive for CD31, CD34, factor-VIII-related antigen. Focal expression of estrogen receptors was detected. No positivity was obtained with progesterone receptor antibodies. The presence of estrogen receptor in the endothelial cells of the hemangioma of the cervix suggests a direct role of this hormone in the hemangioma development. A possible target therapy is discussed.

Problem: Endometriosis (EM) is known as a common estrogen-dependent chronic inflammatory disease. Elevated levels of Forkhead box L2 (FOXL2) have been observed in uterine diseases, including EM. However, the molecular mechanism of FOXL2 in EM needs to be further illustrated.

Purpose: This study aimed to determine estrogen receptor (ER) expression in stromal cells in postchemotherapy tumor bed (PCTB) and its relationship with tumor regression and tumor characteristics.
Methods: The study included 490 breast cancer patients who received neoadjuvant chemotherapy (NAC). We performed ER in stromal cells in all resection specimens and available pre-treatment core biopsy materials of 299 patients immunohistochemically.

Although the impact of gender-affirming hormone therapy (GAHT) on spermatogenesis in trans women has already been studied, data on its precise effects on the testicular environment is poor. Therefore, this study aimed to characterize, through histological and transcriptomic analysis, the spermatogonial stem cell niche of 106 trans women who underwent standardized GAHT, comprising estrogens and cyproterone acetate. A partial dedifferentiation of Sertoli cells was observed, marked by the co-expression of androgen receptor and anti-Müllerian hormone which mirrors the situation in peripubertal boys.

The estrogen receptor alpha (ERα) plays an important role in male reproduction and fertility. Its activity is modulated by phosphorylation of multiple amino acid residues. The ERα phosphorylated at serine 305 (S305) in human cells (homologous with serine 309 in mice) induces ligand-independent ERα activity.

Background: Endometrial cancer remains a significant health concern, with type 1 endometrial cancer characterized by aberrant expression of estrogen-dependent and mTOR pathway proteins. In this study, we evaluated the effects of two novel hydrazone derivatives against the Ishikawa cell line, a model for endometrial cancer.
Methods: Two novel hydrazone derivatives, MVB1 and MVB2, were synthesized and characterized.
