Antimüllerian hormone varies according to the stage of the menstrual cycle, and the day of blood collection may alter the clinical classification of ovarian response in women seeking fertility therapy.

Young and overweight women with PCOS generated thrombin faster than paired controls matched for age and body mass index.

Overweight and obese women with polycystic ovary syndrome who increased their serum 25-hydroxyvitamin D levels more during lifestyle intervention achieved greater improvement in waist circumference and cholesterol.

Variants associated with PCOS in the previously published literature failed to replicate in this case–control association study and meta-analysis.

In a study on tubo-ovarian dysplasia, rats exposed to ovulation stimulation protocols exhibited tubal and ovarian histopathologic and immunohistochemical abnormalities with a dose effect different from those of genetic origin.

CpG-driven innate immune activation can cause activation and amplification of macrophages followed by their migration to the fetomaternal microenvironment, up-regulated tumor necrosis factor-a production, and consequent adverse outcomes of pregnancy.

Junctional proteins regulate vascular permeability in the human corpus luteum. We demonstrate that vascular endothelial cadherin, nectin 2, and claudin 5 are involved in this regulation in a mutually interacting manner.

Lapatinib, which is used in breast cancer treatment, inhibits resumption of meiosis in porcine oocyte-cumulus complexes.

We describe the development of a new valid reliable tool (Egg Donor Informed Consent Tool [EDICT]) for assessing oocyte donors’ understanding of the process and risks associated with oocyte donation.

A case of falsely elevated serum AMH level due to heterophilic interference in an infertile 37-year-old woman with rheumatoid arthritis is reported for the first time.

Women who carry a BRCA mutation experience menopause earlier, on average, than women who do not have a mutation, but the difference does not appear to affect fertility.

A missense mutation of KAL1, c.1828G>A, led to pVal610Ile substitution in two brothers with Kallmann syndrome; their mother is heterozygous for this missense mutation encoded by the single-nucleotide polymorphism rs2229013.

The presence of bilateral endometriomas at the time of IVF affects responsiveness to hyperstimulation but does not affect the quality of the oocytes retrieved and the chances of pregnancy.

We demonstrate the significance of macrophages in the development of endometriosis and the involvement of signal transducer and activator of transcription-3 in interactions between endometrial stromal cells and macrophages.

Women managed in accordance with a conservative surgical philosophy for rectal endometriosis seem to have better digestive outcomes when compared with those managed by the radical approach.

Although quality standards have been set for economic studies, there is considerable room for improvement in such studies in reproductive medicine.

Intrauterine exposure to acceptable levels of diesel exhaust diminishes ovarian reserve of sexually mature mice. The authors recommend more careful examination of the environmental guidelines in humans.

The MTR 2756AA and MTR 2756A–TS 6bp allele combination may contribute to prevalence of recurrent pregnancy loss (RPL) in Korean women.

Spermatozoa of normozoospermic men in idiopathic recurrrent spontaneous miscarriage do not reveal aberrations in DNA methylation at intergenic differentially methylated regions, MEST, ZAC, and LINE-1 CpG islands.

Azoospermia factor region microdeletions were not detected in Slovenian men with IRSA. Our comparisons with previous studies show that Y chromosome microdeletions are most likely not associated with IRSA.
