Addition of nitrous oxide to the carbon dioxide pneumoperitoneum strongly decreases adhesion formation and the dose dependent adhesiogenic effect of blood in a laparoscopic mouse model
The addition of nitrous oxide to the carbon dioxide pneumoperitoneum strongly prevents adhesion formation in a laparoscopic mouse model, with a maximal effect from 5%–10% upward. Blood dose-dependently increases adhesion formation.
Delta like ligand 4 regulates vascular endothelial growth factor receptor 2 driven luteal angiogenesis through induction of a tip stalk phenotype in proliferating endothelial cells
Blockade of Dll4 in an in vivo rodent model shows that VEGFR2-mediated sprouting during luteal angiogenesis is modulated by the Dll4/Notch-1 pathway, which induces a tip/stalk phenotype.
Chronic exposure to a low concentration of bisphenol A during follicle culture affects the epigenetic status of germinal vesicles and metaphase II oocytes
Chronic follicle culture exposure to low bisphenol A affects imprinting and posttranslational histone modifications in mouse oocytes, epigenetic aberrations that might contribute to aneuploidy, altered gene expression, and epigenetic disease.

The potential biomarkers of azoospermia and molecular indicators that could determine particular stages of impaired spermatogenesis can be identified with GeneChip Human Gene 1.0 ST arrays.
Safety and feasibility of performing two consecutive ovarian stimulation cycles with the use of letrozole gonadotropin protocol for fertility preservation in breast cancer patients
Performing consecutive cycles of ovarian stimulation with letrozole and gonadotropin protocol for fertility preservation to maximize oocyte yield before chemotherapy is a feasible approach in women with breast cancer.
Effective method for emergency fertility preservation random start controlled ovarian stimulation
Random-start controlled ovarian stimulation (COS) protocols are as effective as conventional-start COS in fertility preservation and provide a significant advantage by decreasing the total time for embryo/oocyte cryopreservation.
Prospective evaluation of nighttime hot flashes during pregnancy and postpartum
A third of women assessed prospectively during pregnancy and after delivery reported hot flashes during pregnancy/postpartum, for which depressive symptoms, lower education, and higher body mass index were predictors.
Ovulation inducing drugs and ovarian cancer risk results from an extended followup of a large United States infertility cohort
Our findings were generally reassuring in not confirming a link between ovulation-inducing drugs and ovarian cancer; risk was increased, however, among women who, despite having used clomiphene citrate, remained nulligravid.
Identification of multiple and distinct defects in prostaglandin biosynthetic pathways in eutopic and ectopic endometrium of women with endometriosis
Eutopic and ectopic endometrial tissues display distinct anomalies in PG biosynthesis and catabolism pathways.
Differential expression of steroidogenic enzymes according to endometriosis type
In endometriosis, local activation of estrogens appears to be important. Steroid sulfatase and 17b-hydroxysteroid dehydrogenase type 1 inhibitors may therefore prove useful to treat the disease.
Accuracy of a home based device for giving an early estimate of pregnancy duration compared with reference methods
A home pregnancy test with weeks since ovulation results had 93% agreement with time since ovulation and 99% with ultrasound, which provides an estimate more accurate than last menstrual period and earlier than ultrasound.
Peripheral natural killer cell activity as a predictor of recurrent pregnancy loss a large cohort study
Elevated peripheral blood NK cell activity was found to not be an independent risk factor for subsequent miscarriage.
Progesterone elevation does not compromise pregnancy rates in high responders a pooled analysis of in vitro fertilization patients treated with recombinant FSH GnRH antagonist in six trials
Incidence of elevated P increases with ovarian response, and elevated P (>1.5 ng/mL) is independently associated with a decreased chance of pregnancy in low to normal, but not high, responders.
Obstetric and perinatal outcomes in singleton pregnancies resulting from the transfer of blastocyst stage versus cleavage stage embryos generated through in vitro fertilization treatment A systematic review and meta analysis
Singleton pregnancies arising from the transfer of embryos at blastocyst-stage in IVF appear to have higher risk of preterm and very preterm delivery when compared with cleavage-stage transfer.
Thin endometrial stripe does not affect likelihood of achieving pregnancy in clomiphene citrate intrauterine insemination cycles
This study did not find any significant correlation between preovulatory endometrial stripe thickness and likelihood of achieving pregnancy in clomiphene citrate/intrauterine insemination cycles.
A time to look back analysis of morphokinetic characteristics of human embryo development
We define the times associated with morphological changes that occur in embryo development based on time lapse. Subgroups of embryos were compared and related with blastocyst formation and implantation.
The effectiveness of GnRH antagonist in poor ovarian responders undergoing in vitro fertilization a systematic review and meta analysis
In poor responders undergoing in vitro fertilization, the clinical efficacy of a gonadotropin-releasing hormone (GnRH) antagonist was similar to that of a GnRH agonist.
