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.

Both female and male body mass indices (BMI) is important for the outcome of in vitro fertilization/intracytoplasmic sperm injection treatments. Increased female and male BMIs negatively affect the chance of live birth, especially after IVF.

AMH predicts oocyte yield and poor and excessive ovarian response in GnRH antagonist cycles and is associated with increased cumulative live-birth rates after single-blastocyst transfer in fresh and cryopreserved cycles.

Children born after oocyte donation have a higher risk of preterm birth and low birth weight than after standard in vitro fertilization, mainly due to the risk of preeclampsia.

The number of supernumerary vitrified blastocysts correlates positively with the odds of implantation and live birth in single-blastocyst transfers.

The delivery rate after vitrification of embryos derived from vitrified oocytes is not impaired by double vitrification.

Although the controlled ovarian stimulation protocol with short GnRH agonist in alternate days may lower the cost of an individual IVF cycle, it requires more cycles to achieve pregnancy.

Serum hCG levels on the day before oocyte retrieval do not correlate with oocyte maturity.

In a prospective randomized study, addition of recombinant granulocyte-macrophage colony-stimulating factor to IVF embryo culture medium was found to increase ongoing implantation rate at gestational week 12 and live birth rate.

Supplementation of glycoprotein 130 to culture media increased blastocyst formation of human pre-embryos.

The genetic evaluation processes at sperm donor facilities were evaluated. Results show variability in the genetic education content and methods of obtaining informed consent from donor applicants.

Use of isotonic lubricant is safe during collection of semen samples.

Abnormal head shape of fresh motile spermatozoa evaluated by elliptic Fourier analysis reflected sperm DNA fragmentation, providing a rationale for selecting spermatozoa by microscopic shape assessment in the IMSI procedure.

The relationship between semen quality and psychological conditions relative to state and trait anxiety was investigated among 94 volunteer men enrolled in an in vitro fertilization (IVF) program.

Postoperative adhesions are a natural consequence of tissue trauma and healing; however, adherence to microsurgical principles and minimally invasive surgery may help to reduce postoperative adhesions.
