Ovarian yolk sac tumors (YSTs) usually occur in the young women and have been rarely documented in perimenopausal and postmenopausal women. The different age distribution supposes their complex nomenclature and histogenesis. We report a cas…

PURPOSE: To determine whether Aβ40 levels in the follicular fluid (FF) of infertile women undergoing IVF demonstrate a relationship with IVF cycle parameters and outcome. METHODS: FF Aβ40 levels were compared between patients achieving ong…

Adenomyosis is a common, non-neoplastic, chronic gynecologic disorder that is detected in 5% to 70% of hysterectomy specimens. It is characterized by the presence of ectopic endometrial glands and stroma within the myometrium, and it occurs…

OBJECTIVE: To investigate the association of basal testosterone (T) levels with the outcome of in vitro fertilization (IVF) in women with diminished ovarian reserve (DOR). METHODS: Complete clinical data on the first 223 IVF cycles in wome…

Cluster of differentiation 146 (CD146) is an endothelial cell adhesion molecule which is overexpressed in various types of malignant cancer, including ovarian cancer. However, whether CD146 is overexpressed in another two types of gynecolog…

Endometriosis pain is a very common and extremely disabling condition whose mechanism is still poorly understood. While increased levels of leptin have been reported in patients with endometriosis, their contribution to endometriosis pain h…

OBJECTIVE: To evaluate the effect of carbon dioxide (CO2) pneumoperitonal pressure on the ultrastructure of implanted endometriotic lesions in a rat model. STUDY DESIGN: An endometriotic model was established in Sprague-Dawley rats with pe…

HNF1B is overexpressed in clear cell epithelial ovarian cancer, and we observed epigenetic silencing in serous epithelial ovarian cancer, leading us to hypothesize that variation in this gene differentially associates with epithelial ovaria…

Infection by human papillomavirus (HPV) can cause cervical intraepithelial neoplasia (CIN) and cancer. Down-regulation of E6 and E7 expression may be responsible for the positive clinical outcomes observed with IFN treatment, but the molecu…

OBJECTIVE: To investigate the relationship between the size of an excised endometrioma and the magnitude of damage to the ovary after the surgery. DESIGN: A retrospective, controlled study. SETTING: A university hospital. PATIENT(S): Eig…

OBJECTIVE: Embryo implantation is directly affected by genes related to uterine receptivity. Studies have demonstrated the important roles of miRNAs in the regulation of gene expression. Our early miRNA chip analyses revealed that the mmu-m…

While chronic pain is a main symptom in endometriosis, the underlying mechanisms and effective therapy remain elusive. We developed an animal model enabling the exploration of ectopic endometrium as a source of endometriosis pain. Rats were…

OBJECTIVE: To investigate factors with pelvic adhesions and the effect of different degrees pelvic adhesions on fallopian tube recanalization in infertile patients. METHODS: Total of 527 infertile patients undergoing hysteroscopy and lapar…

Elevated levels of lysophosphatidylcholine (lysoPC), present in oxidatively damaged low-density lipoprotein (oxLDL), are implicated in cardiovascular complications. LysoPC is generated by free radical-catalyzed oxidation of polyunsaturated …

PAX8 is a nuclear transcription factor with limited expression in normal and neoplastic tissues in a cell lineage-dependent manner. PAX8 has been detected in embryonic Müllerian ducts, human fallopian tubes, and ovarian carcinomas. However,…

Ovarian clear cell carcinoma (CCC) is a unique type of ovarian cancer characterized by distinct clinicopathological and molecular features. CCC is considered to be a highly malignant disease because it is resistant to conventional chemother…

OBJECTIVE: To evaluate the combined effect of endometrial thickness and pattern on clinical outcome in patients undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). METHODS: Cycles of IVF/IC…

PURPOSE: Advanced ovarian clear cell carcinoma (CCC) is one of the most aggressive ovarian malignancies, in part because it tends to be resistant to platinum-based chemotherapy. At present, little is known about the molecular genetic altera…

OBJECTIVE: Our study is to investigate whether tyrosine kinase receptor B (TrkB) is expressed in eutopic endometrium of women with adenomyosis and its association with clinical characteristics. METHODS: We collected endometrial tissues fro…

OBJECTIVE: We sought to investigate the effectiveness of repeated transvaginal ultrasound-guided aspiration of endometriomas in infertile women with endometriosis. STUDY DESIGN: A retrospective study was performed in our department of repr…

OBJECTIVE: To evaluate the value of transvaginal hydrolaparoscopy (THL) in infertile women with abnormal hysterosalpingogram results but with no history of previous pelvic surgery and with normal gynecological examination and vaginal sonogr…

OBJECTIVE: To evaluate effects and safety of gonadotrophin-releasing hormone agonist (GnRH-a) combined with transdermal estradiol and medroxyprogesterone acetate in the treatment of endometriosis. METHODS: From January 1st, 2007 to July 31…

To investigate the effect of oral and transdermal estrogen replacement therapy (ERT) on the expression of different estrogen receptor (ER) subtypes and the secretion of immunoregulatory cytokines, we performed a clinical investigation on pr…

OBJECTIVE: To investigate whether focal adhesion kinase (FAK) is expressed in endometriotic ovarian tissue. METHODS: We collected tissue samples from the ovaries of 41 women with ovarian endometriosis and from the endometrium of 20 healthy…

Over 22,000 cases of ovarian cancer were diagnosed in 2007 in the United States, but only a fraction of them can be attributed to mutations in highly penetrant genes such as BRCA1. To determine whether low-penetrance genetic variants contri…
