BACKGROUND Myolysis is one of the procedures that is claimed to provide significant improvement in myoma status without hysterectomy. Myolysis procedures have been generally performed via laparoscopy, and there are limited data on transvaginal radiofrequency (RF) myolysis. This study investigated the feasibility, efficacy and safety of transvaginal(More)
OBJECTIVE To investigate whether levothyroxine (LT4) treatment has beneficial effects on IVF results and pregnancy outcome in infertile patients with subclinical hypothyroidism undergoing IVF/intracytoplasmic sperm injection (ICSI). DESIGN Prospective, randomized trial. SETTING University-affiliated infertility clinic. PATIENT(S) A total of 64(More)
Heat shock proteins (HSPs) are known to play an important role not only in various stress conditions such as exposure to heat shock, but also in normal development and/or differentiation. The role of small heat shock proteins such as HSP25 in early embryo development remains largely unknown. In the present study, we examined temporal and spatial expression(More)
OBJECTIVE To investigate the effectiveness of GnRH antagonist multiple-dose protocol (MDP) with oral contraceptive pill (OCP) pretreatment in poor responders undergoing IVF/ICSI, compared with GnRH antagonist MDP without OCP pretreatment and GnRH agonist low-dose long protocol (LP). METHODS A total of 120 poor responders were randomized into three groups(More)
This study was performed to evaluate the effects of fibroblast co-culture on in vitro maturation (IVM) of prepubertal mouse preantral follicles. The intact preantral follicles were obtained from the ovaries of 12-14 day old mice and these were cultured individually in α-minimal essential medium (α-MEM) supplemented with 5% fetal bovine serum (FBS), 100(More)
BACKGROUND Hyperandrogenism (HA) has been linked with several components of metabolic syndrome (MetS). Few studies in Asian women have evaluated the important risk factors for and prevalence of MetS according to PCOS subtype. In this study, we investigated differences in metabolic parameters and the prevalence of MetS in two major phenotypic subgroups of(More)
Radical trachelectomy is a promising fertility-sparing treatment for patients with early stage cervical cancer who want to preserve their fertility. However, isthmic stenosis occurs frequently in patients who received radical trachelectomy and it is one of the causes of infertility following radical trachelectomy. Moreover, despite the treatment for(More)
OBJECTIVE To evaluate whether letrozole incorporated in a gonadotrophin-releasing hormone (GnRH) antagonist multiple dose protocol (MDP) improved controlled ovarian stimulation (COS) and in vitro fertilization (IVF) results in poor responders who underwent IVF treatment. METHODS In this retrospective cohort study, a total of 103 consecutive IVF cycles(More)
Twin pregnancy consisting of complete hydatidiform mole (H-mole) and a coexisting fetus occurs with an estimated incidence of 1 per 22,000–100,000 pregnancies. The incidence of this unusual twin pregnancy with complete H-mole and a coexisting fetus after in vitro fertilization and embryo transfer (IVF–ET) is not thought to be greater than that of general(More)
OBJECTIVE To evaluate the effect of progesterone supplementation during the luteal phase on pregnancy outcome in natural frozen-thawed embyo transfer (FTET) cycles. METHODS In this retrospective cohort study, 228 consecutive patients who underwent FTET cycles between January 2009 and September 2012 were included. One hundred forty-five patients received(More)
