RESEARCH QUESTION: This study aimed to retrospectively evaluate the efficacy of a hyaluronan-enriched transfer medium (HETM) for transfer failures and transfer of frozen embryos that have been graded as C at the time of transfer according t…

BACKGROUND: Ectopic pregnancy (EP) occurs in 1% of pregnancies and is reported to be more common in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) pregnancies. An abdominal ectopic pregnancy (AEP) is a rare form of EP, a…

Adenomyosis has only been reported in one patient with mosaic Turner syndrome. We report a case of mosaic Turner syndrome in a patient who suffered from hypermenorrhoea and severe anaemia due to adenomyosis. A 40-year-old woman visited us d…

This paper reports two cases showing transient thyrotoxicosis caused by prolonged use of gonadotropin-releasing hormone (GnRH) agonist. Case 1, a 31-year-old woman, was administered GnRH-agonist (leuprorelin acetate) for treatment of endome…

PURPOSE: For this study, the impact of basal FSH levels on ART outcomes was assessed. METHODS: From June 2003 to May 2006, 191 ART cycles were performed in our hospital. All cases were treated with GnRH-a long protocol. The patients were c…

PURPOSE: To evaluate the cystectomy-induced damage on the follicular growth and ovulation of an affected ovary during natural cycles. METHODS: Twenty-eight infertile patients with unilateral ovarian endometriomas who underwent laparoscopic…

PURPOSE: To establish an index to predict ART outcomes and to identify infertile patients who need LH supplementation during ovarian stimulation. METHODS: Serum LH concentrations were measured during the mid- and late-follicular phase in 8…

AIM: To clarify the effect of laparoscopic cystectomy for ovarian endometrioma in infertility patients, the pregnancy outcome was evaluated. METHODS: This was a retrospective study. From August 2002 to February 2006, 33 infertility patient…

AIM: Women with unexplained infertility frequently become pregnant after diagnostic laparoscopy. In this study the effect of laparoscopic surgery on such women was evaluated by the pregnancy rate after laparoscopic surgery. METHODS: A tota…

Aim:  The aim of the present study was to establish a standard protocol for ovarian stimulation with gonadotropin-releasing hormone analog (GnRH-a) long protocol using recombinant-follicle stimulating hormone (rec-FSH) preparations for assi…

PURPOSE: Intraovarian arterial blood flows before and after follicular rupture in ovulation induced cycles were examined by transvaginal color flow Doppler imaging. The changes observed in the intraovarian arterial resistance before and aft…

PURPOSE: To demonstrate our hypothesis that a correlation exists between oocyte maturity and a decrease in intraovarian blood flow resistance in assisted reproductive technology (ART) treatment cycles, oocyte maturity and total antioxidant …
