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…

Endometriosis is a multifactorial disease mostly affecting women of reproductive age. An additive effect between inflammation and stress reaction on the growth of endometriosis has been demonstrated. Here we investigated the combined effect…

OBJECTIVES: Human heat shock protein 70 (HSP70) has been reported to enhance Toll-like receptor 4-mediated pelvic inflammation and growth of endometriotic cells. However, information on tissue expression of HSP70 before and after treatment …

STUDY QUESTION: Is there any risk of intra-uterine bacterial colonization and concurrent occurrence of endometritis in women with endometriosis? SUMMARY ANSWER: An increase in intra-uterine microbial colonization and concurrent endometriti…

Endometriosis is a multifactorial disease mostly affecting women of reproductive age and is associated with chronic pelvic pain and infertility. Even after 300 years, most of the literature claims that pathogenesis and/or pathophysiology of…

STUDY QUESTION: Is there any combined effect between inflammation and stress reaction on Toll-like receptor 4 (TLR4)-mediated growth of endometriotic cells? SUMMARY ANSWER: A combined effect of local inflammation and stress reaction in the…

Study question: To compare the pregnancy rate in patients submitted to FET (Frozen Embryos Transfer) of cleavage stage embryos (Group 1), or at the blastocyst stage (Group 2). Summary answer: Our data showed that the transfer of frozen blas…

STUDY QUESTION: Is there any occurrence of hidden (occult) endometriotic lesions in normal peritoneum of women with and without visible endometriosis? SUMMARY ANSWER: We detected a slightly higher occurrence of occult microscopic endometri…

Endometriosis is an estrogen-dependent chronic inflammatory condition associated with variable degrees of pelvic pain and infertility. Studies have showed that the growth and progression of endometriosis continue even in ovariectomized anim…

STUDY QUESTION: Is the occurrence of pelvic pain in women with ovarian endometrioma associated with coexisting peritoneal lesions (PLs)? SUMMARY ANSWER: Pelvic pain in women with ovarian endometrioma is usually associated with coexisting P…

STUDY QUESTION: Can prostaglandin E(2) (PGE(2)) in menstrual and peritoneal fluid (PF) promote bacterial growth in women with endometriosis? SUMMARY ANSWER: PGE(2) promotes bacterial growth in women with endometriosis. WHAT IS KNOWN ALREA…

We measured serum anti-Müllerian hormone levels before and after surgery in women undergoing unilateral and monolocular cystectomy for benign ovarian diseases. Comparing to control benign cysts, we found a significant decline in serum anti-…

BACKGROUND: We recently demonstrated the effect of gonadotrophin-releasing hormone agonist (GnRHa) on tissue inflammation, angiogenesis and apoptosis in endometriosis, adenomyosis and uterine myoma. Here, we investigated expression of GnRH …

OBJECTIVES: We investigated the effect of human seminal fluid on the growth of endometrial cells derived from women with and without endometriosis. STUDY DESIGN: Seminal plasma (SP) was collected from 18 healthy fertile men. Serum, periton…

To test the hypothesis that bacterial contamination of menstrual blood could be a local biologic event in the development of endometriosis, menstrual blood was cultured and bacterial endotoxin was measured in menstrual blood and peritoneal …

BACKGROUND: Information is limited regarding the multifunctional role of GnRH agonist (GnRHa) therapy in reproductive diseases. We investigated the pattern of changes in inflammatory reaction, micro-vessel density and apoptosis in the tissu…

Macrophages, dendritic cells, and Toll-like receptors (TLRs) are integral components of the innate immune system. This rapidly reactive system responds immediately to infectious or other non-self agents, thereby inducing an inflammatory res…

Endometriosis, a chronic disease characterized by endometrial tissue located outside the uterine cavity is associated with chronic pelvic pain and infertility. However, an in-depth understanding of the pathophysiology of endometriosis is st…

Endometriosis, a chronic disease characterized by endometrial tissue located outside of the uterine cavity and is associated with chronic pelvic pain and infertility. However, an in-depth understanding of the pathophysiology of endometriosi…

BACKGROUND: We investigated the role of human heat-shock protein 70 (Hsp70) in Toll-like receptor 4 (TLR4)-mediated growth of endometriosis. METHODS: TLR4 expression was examined in macrophages (M) isolated in primary culture from the peri…

BACKGROUND: The association between uterine myoma and infertility is still controversial. The anatomical defect of endometrium by uterine fibroids could be a factor for reducing pregnancy rates and increasing miscarriage rates. However, pre…
