Higher self-reported past year physical activity was associated with favorable pregnancy outcomes following in vitro fertilization (IVF). Physical activity and sedentary behavior following IVF were not associated with pregnancy outcomes.

Genome-wide lncRNA expression patterns of ovarian endometriosis tissue are profiled by microarray, compared with paired eutopic endometrium. Nearly 1,000 lncRNA transcripts are found dysregulated.

Formation of endometriomas may cause focal exhaustion of the stockpile of primordial follicles by upregulation of recruitment and atresia of follicles at early developmental stages, which may eventually result in a decreased ovarian reserve.

There was a high prevalence of chronic endometritis in a cohort of 395 women with pregnancy loss. “Test of cure” was 100% with antibiotics. Subsequent live-birth rates were encouraging.

This study examined the differences in maternal characteristics and pregnancy outcomes between women with ovulatory dysfunction and tubal obstruction who underwent assisted reproductive techniques.

Antimüllerian hormone is highly correlated with number of eggs retrieved. Very low levels are associated with diminished yet reasonable pregnancy rates, mediated through number of oocytes retrieved as opposed to oocyte quality.

Two case reports are presented, in which GnRH triggering and the freeze-all approach in a GnRH antagonist protocol resulted in the development of severe OHSS, requiring hospitalization and peritoneal drainage.

In ncIVF treatment OR scheduling based on the occurrence of spontaneous LH surge yields acceptable oocyte recovery, fertilization, and embryo cleavage rates.

Positive predictive factors of pregnancy after IUI-H were woman’s secondary infertility, woman basal FSH levels 7 IU/L, ovulation triggering and inseminated progressive motile spermatozoa 1 million.

In women with unilateral unoperated endometriomas undergoing IVF, ovarian responsiveness and oocyte developmental competence did not differ between the affected and intact gonads.

The presence of early cleavage does not seem to improve implantation after the usual morphologic evaluation of cleavage-stage embryos.

Assisted reproductive technology induces alterations in the expression and methylation status of INSIG1 and SREBF1 in the fetus and the placenta.

The retrieval of >15 oocytes in fresh autologous IVF cycles significantly increases the risk of ovarian hyperstimulation syndrome without improving live-birth rate.

Levels of aldehyde dehydrogenase-1A2 (ALDH1A2), which synthesizes retinoic acid, are significantly reduced in testicular tissue from men with infertility compared with controls, suggesting an association between ALDH1A2 and male infertility.

Areas of spermatogenesis may be missed with conventional testicular sperm extraction (TESE) in azoospermic men with testicular cancer. Microdissection TESE should be offered at orchiectomy to maximize sperm retrieval.

Men with mosaic Klinefelter syndrome (KS) seem to be more well androgenized than their non-mosaic KS counterparts, both with respect to hormones and sperm in the ejaculate.

Variability in the morphologic assessment of human sperm is determined using the criteria recommended by the WHO in 2010, and the results reveal that a stricter definition of each defect is needed.

Effects of coital lubricants and oils on sperm motility were evaluated. Astroglide, KY lubricants (Sensitive, Warming, and Tingling), and sesame oil reduced sperm motility significantly, and mustard oil exposure caused sperm hyperactivation.
