Purpose: To evaluate the frequency of intrauterine adhesion (IUA) after hysteroscopic myomectomy, and to analyze the association of IUA and the location of submucous myomas and the use of postoperative barrier (POB).

Methods: Hysteroscopic myomectomy was performed in 217 patients with submucous myomas. The retrospective investigation was performed, and the cases were divided into three groups: cases with solitary submucous myoma (SSM; group 1), cases with apposing submucous myomas (ASMs; group 2) and cases with submucous myomas that were far from each other or not in apposition to one another (not apposing submucous myomas: NASMs; group 3).

Purpose: To evaluate the efficacy of silicone sheet as a new type of barrier for preventing adhesion reformation following hysteroscopic adhesiolysis of intrauterine adhesions (IUAs).

Methods: Hysteroscopic adhesiolysis was performed for 36 patients with IUAs. The adhesion reformation rate was retrospectively compared between 26 patients treated with silicone sheet (group 1) and 10 patients treated with an intrauterine device wrapped in oxidized regenerated cellulose as a barrier (group 2).

Aim: The aim of this study was to clarify the role of dilatation and curettage (D&C) performed for spontaneous or induced abortion in the etiology of endometrial thinning.

Methods: This was a retrospective and cross-sectional study of 310 infertile patients from January 2013 through December 2015. Endometrial thickness observed 5-7 days after ovulation in a natural menstrual cycle was correlated with the number of D&C noted in each patient's history.

Matrix metalloproteinases (MMP) are capable of degrading a variety of extracellular matrix (ECM) proteins and are also involved in the processing of a number of bioactive molecules. Our findings indicate that the functions of MMP in the ovary and uterus are organ-specific and time-dependently vary during the reproductive cycle. Prolactin induces structural luteolysis indicated by loss of luteal weight, protein and DNA within 36 h after pretreatment with ergot alkaloid.

The most severe complication of ovarian hyperstimulation syndrome (OHSS) is thromboembolism, which is related to hemoconcentration. Dextran 40 infusion has greater effectiveness for the treatment of hemoconcentration due to OHSS than does human albumin infusion.

Background: An approach consisting of elective cryopreservation of all embryos has been proposed for patients at risk of ovarian hyperstimulation syndrome (OHSS). Although elective cryopreservation can prevent pregnancy-induced late OHSS, it cannot prevent early OHSS. Early OHSS is reported to have been complicated with thromboembolism.
