Optimal adult human SSC recovery is achieved with testicular cell suspension cryopreservation, whereas similar fetal SSC recovery was achieved with both tissue and single cell suspension cryopreservation.

Mammalian target of rapamycin signaling pathway regulates spermatogonial stem cell differentiation via stimulated retinoic acid gene 8 (Stra8).

We demonstrate that nucleolar channel systems are present during the window of endometrial receptivity previously identified by their transcriptomic signature using the endometrial receptivity array.

Dopamine receptor 2 agonist prevents vascular permeability in an ovarian hyperstimulation syndrome rat model by decreasing ovarian vascular endothelial growth factor production.

Prenatally androgenized rats had aberrant metabolic and polycystic ovary morphology similar to human polycystic ovary syndrome (PCOS). Changesof DNA methylation may be an important factor for epigenetic programming of PCOS during development.

A rhesus monkey model indicates that repeated controlled ovarian hyperstimulation could potentially affect the development and function of ovarian cells in the long term.

Women with hyperandrogenic polycystic ovary syndrome (PCOS) show a more unfavorable cardiometabolic profile compared with women with nonhyperandrogenic PCOS. However, screening for cardiovascular risk factors is crucial in all women with PCOS.

More-severe menstrual pain is associated with lower antimullerian hormone concentration among Japanese women age 20–22 years who had never used oral contraceptives; the effect persisted even after adjustment for menstrual-cycle regularity.

Polycystic ovary morphology according to the modified Rotterdam criteria in a nongynecologic cohort in our study is less common than previously reported. Transabdominal ultrasound may be a useful tool in the evaluation of polycystic ovary syndrome, even in obese adolescents.

Experiences of CBRC clinical care received by participants were generally rated positive in terms of treatment costs, safety, and information provided, although counseling needs being met were rated less favorably.

In a population-based sample, infertility treatment as recorded on the birth certificate was not associated with symptoms of postpartum depression.

Although posthumous assisted reproduction (PAR) appears to be acceptable to a majority of IVF users, further research is required on how to ensure that their consent for PAR is well informed.

The first series of pregnancies achieved after UPA treatment is reported.

Pain in hysteroscopy is related to the presence of synechiae in the cervical canal, to the duration of the procedure, and to the use of normal saline as a distension medium.

This study demonstrated that the rs10965235 single-nucleotide polymorphism in the CDKN2B-AS gene and the rs16826658 single-nucleotide polymorphism near the WNT4 gene were significantly associated with endometriosis in a Korean population.

A novel microarray platform was developed offering the possibility of combined aneuploidy screening, genetic fingerprinting, and mitochondrial DNA (mtDNA) assessment of embryos. Associations between mtDNA and maternal age are reported.

Fertility preservation patients report higher levels of depression and anxiety at the onset of treatment than infertility patients, but infertility patients’ symptoms worsen across treatment.

Reproductive endocrinology and infertility practices in areas with a higher percentage of Hispanics are more likely to translate into Spanish. Practices with a translated website use social media more often.

Japan’s recent temperature fluctuation seems to be linked to a lower male:female ratio of newborns, partly via increased male fetal deaths, suggesting vulnerability ofmale concepti to external stresses, including climate changes.

Dydrogesterone supplementation in women with recurrent pregnancy loss improves ongoing pregnancy rates.
