OBJECTIVE: We report a case of a chromosomally normal twin pregnancy following the transfer of one euploid female embryo and one chaotic male embryo with six aneuploidies, including trisomy 21, identified through preimplantation genetic tes…
BACKGROUND: Natural cycle frozen embryo transfer (NC-FET) lowers obstetric risks by preserving ovulation and corpus luteum but limits scheduling flexibility. Natural proliferative phase FET (NPP-FET) offers a scheduling-friendly alternative…
Intracytoplasmic sperm injection (ICSI) is the most effective procedure to resolve male infertility, enhancing overall fertilization and pregnancy outcomes. However, it is important to note that fertilization failure (FF) can still occur in…
INTRODUCTION: The failure of remodeling the spiral arteries is associated with the pathogenesis of preeclampsia. Estradiol (E2) plays a crucial role in placentation and may be involved in the development of preeclampsia. However, there is a…
BACKGROUND: Fallopian tube serous adenofibromas are uncommon tumors of the female genital tract, only dozens of cases have ever been reported. Earlier study indicated that they might be derived from embryonic remnants of the Müllerian duct.…
BACKGROUND: The previous model-based cost-effectiveness analyses regarding elective oocyte cryopreservation remained debatable, while the usage rate may influence the cost per live birth. The aim of this study is to disclose the usage and c…
The optimal timing of frozen-thawed blastocyst transfer following hysteroscopic polypectomy is an important and unanswered clinical question. In this study, we conducted a retrospective survey of cases from an infertility center at an acade…
BACKGROUND: The aim of this study was to evaluate the efficacy and safety of a recombinant human follicle stimulating hormone (r-FSH) low-dose step-up regimen for controlled ovarian hyperstimulation in patients undergoing ovulation inductio…
Uterine adenomyosis was first reported in the 19(th) century and early 20(th) century; von Rokitansky described it in 1860. Since then, the general clinical, pathological, and radiologic findings and potentially useful management methods ha…
BACKGROUND: An endometrial polyp is a frequently encountered gynecologic disease with abnormal uterine bleeding and infertility being the two common presenting problems, and hysteroscopic polypectomy is an effective method to remove them. T…
BACKGROUND: We sought to determine the association between factors that affected clini- cal pregnancy and live birth rates in patients who underwent in vitro fertilization (IVF) and received intracytoplasmic sperm injection (ICSI) and/or la…
OBJECTIVE: Insertion of the levonorgestrel-releasing intrauterine system Mirena is difficult in women with adenomyosis, and the device is often subsequently expelled. We used a novel insertion technique (Yang's method) to overcome this prob…
OBJECTIVE: To investigate cell invasiveness and the production of matrix metalloproteinase-2 (MMP-2), MMP-9, tissue inhibitor of metalloproteinase-1 (TIMP-1) and TIMP-2 in endometrial stromal cells (ESCs) of adenomyosis. DESIGN: Prospectiv…
PURPOSE: To evaluate the effect of extended estrogen administration for women with thin endometrium in frozen-thawed in-vitro fertilization (IVF) programs. METHODS: Thirty-six women undergoing IVF program had thin endometrium (<8 mm). Amon…
