We introduce a new technique that combines laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in patients with congenital atresia of the cervix.

We describe the differential microRNA profiles in the follicular fluid and granulosa cells of in vitro fertilization patients depending on their age and oocyte maturation stage.

Altered expression of vascular endothelial growth factor angiogenic factors in peri-implantation endometrium may provide an explanation for the impairment of endometrial receptivity in women who have high P levels before oocyte retrieval.

Dichloroacetate modulates redox homeostasis, thus protecting cells against anaerobic metabolism and associated oxidative stress. This may provide targets for therapeutic intervention for treatment of profibrotic disorders, including postoperative adhesions.

New automated AMH assays provide substantially lower values than existing AMH enzyme-linked immunosorbent assays. Assay-specific interpretation is necessary, along with international standardization.

Nine women with uterine factor infertility and their partners underwent psychological evaluations, by questionnaires, before and after uterus transplantation. The participants were psychologically stable throughout the 1-year observation time.

A cryopreservation method for a few spermatozoa using an agarose capsule was established. The method will be useful for intracytoplasmic sperm injection treatment in patients with few spermatozoa.

A large assisted reproductive technology registry study finds that blastocyst transfer does not increase the risk of preterm birth, low birth weight, or small for gestational age.

Urinary concentrations of two benzophenone-type ultraviolet filters (BP-2, BP-8), chemicals used as sunscreens, were found to be associated with select semen endpoints.

Ovulation-stimulating drugs were unrelated to lung or colorectal cancer risks, but possibly related to slight risk increases for melanomas and thyroid cancers, supporting the need for further evaluation of these cancers.

Men’s poultry intake was positively related to fertilization rate in in vitro fertilization (IVF) and intracytoplasmic sperm injection cycles, while processed meat intake was inversely related to fertilization rate in IVF cycles only.

In a population-based case–control study, we observed increased endometriosis risk with regular infant soy formula feeding. Our data suggested that intrauterine diethylstilbestrol exposure and premature birth were associated with endometriosis.

Decidualizing signals reduce deoxyribonucleic acid methyltransferase 3B (DNMT3B) expression in eutopic endometrial stromal cells but not in endometriotic stromal cells. This affects DNMT3B chromatin occupancy across genes with aberrant DNA methylation in endometriosis.

Genetic and unique environmental influences on the etiology of endometriosis further strengthen the conclusion that genes have a strong influence on the phenotypic manifestations of endometriosis.

Altered levels of circulating miR-200a and miR-141 but not miR-200b were observed in plasma samples of women with endometriosis. The levels of the miRNAs studied were influenced by the circadian rhythm.

Early in vitro fertilization pregnancies screened by a clinical algorithm incorporating human chorionic gonadotropin levels and symptoms can be evaluated with early ultrasound for efficient diagnosis and treatment of ectopic and heterotopic pregnancy.

Chronic endometritis is prevalent among women with recurrent pregnancy loss and may contribute to poor pregnancy outcomes.

Within the first 5 years after sterilization reversal, at least 50% of women sterilized before the age of 40 years successfully deliver a child, but the delivery rate halves after the age of 40 years.

This randomized, controlled trial suggests that, for women with regular ovulatory cycles undergoing frozen embryo replacement in vitro fertilization, the live birth rate is similar whether the endometrium is prepared using a natural menstrual cycle or GnRH-agonist pituitary suppression and hormone replacement therapy.

We developed a diagnostic tool using a combination of proteomic fingerprinting and time-lapse morphokinetic analysis to select embryos for transfer according to their implantation potential.
