OBJECTIVE: Incarcerated gravid uterus is a condition in which uterine myoma and intraperitoneal adhesion lead to persistent uterine retroversion. Accurate diagnosis before cesarean section is crucial so that the procedure can be planned wit…

Cesarean section in breech or transverse presentation involves more complicated procedures than cesarean section in cephalic presentation because the former requires additional manipulations for guiding the presenting part of the fetus, lib…

Vitamin D (VD) deficiency is associated with reproductive failure. However, the relationship between VD and maternal immunity remains unclear. We investigated the clinical efficacy of VD in maternal T-helper (Th) cytokines in 276 infertile …

PurposeOf those patients who undergo open surgery for a suspicion of malignant transformation of endometrioma (MTOE) due to solid nodule enhancement identified by contrast-enhanced magnetic resonance imaging (MRI), some benign endometrioma …

BACKGROUND: Ovarian endometriomas affect a substantial proportion of women of reproductive age who may have a potential risk of diminished ovarian reserve (DOR) after ovarian cystectomy. Here, we investigated the risk factors for pre-surgic…

PurposeThyroid dysfunction and autoimmune thyroiditis are associated with fertility in women of reproductive age. Anti-Müllerian hormone (AMH), a known biomarker of ovarian function, may be affected by impaired thyroid function; however, th…

OBJECTIVE: We conducted a single-center study to evaluate the usefulness of the magnetic resonance (MR) imaging jelly method for diagnosing endometriosis-associated adhesions in the Pouch of Douglas. METHODS: Thirty women with menstrual pai…

BackgroundDecidualizing human endometrial stromal cells (HESCs) profoundly up-regulate 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1), the enzyme that converts inert cortisone to active cortisol. We postulated that the induction of a cor…

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…

Time spatial labeling inversion pulse (Time-SLIP) is a non-contrast magnetic resonance angiography (MRA) technique. No cases in which this technique was used during pregnancy have been reported. We report herein two cases with adenomyosis o…

AIM: The rate of oocyte decline follows a biphasic pattern, characterized by acceleration between 32 and 38 years old. Ovarian reserve is also affected by external factors, including ovarian disease and iatrogenic damage. The aim of this st…

UnlabelledBACKGROUND AND OBJECTS: To examine the learning curve of minimally invasive 2-port total laparoscopic myomectomy (TTLM).MethodsTTLM was performed by using only umbilicus and left inguinal ports, for 30 patients at our university a…

PurposeTo evaluate preoperative magnetic resonance (MR) imaging features of bleeding and non-bleeding ectopic pregnancy (EP) by comparison with surgical findings.MethodsEighteen suspected EP cases underwent preoperative MR imaging. We class…

A 41-year-old woman carrying a germline tuberous sclerosis complex 2 (TSC2) mutation, whose regular medical follow-up for tuberous sclerosis complex and tuberous sclerosis complex-associated lymphangioleiomyomatosis had continued for 2 year…

There are two different types of hysterocopes available: Flexible and rigid. Flexible scopes have the ability to observe the whole intrauterine cavity, but it is difficult to perform an operation on endometrial lesions. Rigid hysteroscopes …
