Obstructed hemi-vagina and ipsilateral renal agenesis (OHVIRA) syndrome is a complex of Müllerian and Wolffian duct anomalies constituted by obstructed hemi-vagina that may form hematocolpos with ipsilateral renal anomaly and different degr…

PROBLEM: Despite abundant reports on the risk role of uterine outflow tract obstruction in endometriosis, information on the occurrence of endometriosis in women with Chlamydia trachomatis infection causing fallopian tube obstruction is unk…

Infertility is a main manifestation of endometriosis, though the exact pathogenesis of endometriosis-associated infertility remains unclear. Compromised ovarian functions may be one of the causes of endometriosis related infertility. The ov…

[Background] As its name indicates, anti-Müllerian hormone (AMH) is primarily found as an inhibitor of Müllerian duct in male fetus. On the other hand, AMH may act as a mediator of Müllerian duct derived female tissue, such as endometrium i…

Abstract Background Surgery for endometriomas may cause detrimental effects on ovarian reserve. In this study, we evaluated the efficacy of three-step laparoscopic surgery for endometriomas utilizing novel progestin, dienogest in terms of p…

Abstract Purpose Surgery for endometriomas may cause detrimental effects on ovarian reserve. We evaluated the safety of three‐step laparoscopic surgery for endometriomas utilizing dienogest in terms of post‐surgical ovarian reserve. Methods…

BACKGROUND: Autoimmune reactions and subsequent inflammation may underlie spermatogenic dysfunction and endometriosis-related infertility. The aim of this study is to identify disease-specific antigens in immune complexes (ICs) in seminal p…

BACKGROUND: Endometriosis is a multifactorial disease that mainly affects women of reproductive age. The exact pathogenesis of this disease is still debatable. The role of bacterial endotoxin (lipopolysaccharide, LPS) and Toll-like receptor…

The ovaries of women of reproductive age may show specific histological structures that may relate to the maintenance of primordial follicles and the regulation of early follicular development, which are keys to understanding the dynamics o…

Endometrioma is one of the main pathologies of endometriosis, though its pathogenesis still remains enigmatic. Ovarian reserve is defined as the number and quality of the follicles left in the ovary at any given time. The cause of infertili…

BACKGROUND: The different macromolecules as secreted by macrophages (Mw) in the pelvic environment are believed to enhance the growth of endometriosis. However, the possible mediator that stimulates Mw for the production of different growth…

Adenomyosis is commonly believed to arise from the basalis endometrium. As an estromedin growth factor, hepatocyte growth factor (HGF) exhibits multiple functions in endometriosis, a disease commonly believed to arise from the functionalis …

The human lower genital tract is constantly exposed to various microorganisms, which can infect the upper genital tract through ascending migration. We report on tests of the hypothesis that as normal microbial flora in the vagina, some gra…
