Early Pregnancy Outcomes in Fresh Versus Deferred Embryo Transfer Cycles for Endometriosis-Associated Infertility: A Retrospective Cohort Study.

Given the estrogen-dependence associated with endometriosis, hyper-stimulation associated with assisted reproduction treatment may exacerbate the disease process and adversely affect endometrial receptivity and subsequent implantation. In this way, a freeze-all deferred embryo transfer (ET) approach may benefit patients with endometriosis, although controversy exists regarding the mechanism of endometriosis-associated infertility and benefits of deferred ET on endometrial receptivity. Hence, the purpose of this study was to compare in vitro fertilization (IVF) outcomes in women with endometriosis, diagnosed by histology, undergoing fresh versus deferred-ET after elective cryopreservation.

DuoStim cycles potentially boost reproductive outcomes in poor prognosis patients.

Aim: To evaluate the overall performance and oocyte quality of follicular phase stimulation (FPS) vs. luteal phase stimulation (LPS) among patients undergoing double ovarian stimulation (DuoStim).

Materials And Methods: Observational retrospective two-center cohort study including 79 infertile women who underwent a total of 87 DuoStim cycles between January 2017 and May 2019.

Impact of Endometrial Preparation Protocols for Frozen Embryo Transfer on Live Birth Rates.

Background: It has been reported that a natural cycle (NC) is similar to or even better than hormone replacement therapy (HRT) in patients with regular cycles who undergo frozen embryo transfer (FET). Hundreds of FETs are managed yearly in our clinic. Scheduling these cycles is critical in a busy unit like ours.

Effect of exogenous xylanase on rumen in vitro gas production and degradability of wheat straw.

The objective of this study was to determine effects of xylanase on in vitro gas production (GP) and in sacco degradability of wheat straw. Rumen fluid was obtained from three Mongolian native goats fitted with permanent rumen cannulas. The trial consisted of five doses (0, 0.

Impact of final oocyte maturation using gonadotropin-releasing hormone agonist triggering and different luteal support protocols on endometrial gene expression.

Objective: To use microarray technology to analyze endometrial gene expression after gonadotropin-releasing hormone agonist (GnRH-a) triggering with four different protocols of luteal support in comparison with results obtained after a human chorionic gonadotropin (hCG) trigger.

Design: Prospective, randomized, controlled trial.

Setting: University-affiliated private assisted-reproduction center.

Domestic sewage sludge composting in a rotary drum reactor: optimizing the thermophilic stage.

The aim of this paper was to study the influence of four process variables (turning frequency, gas-phase oxygen level, type of bulking agent and sludge/bulking agent mixing ratio) on the performance of the sewage sludge composting process using a rotary drum pilot scale reactor, in order to optimize the thermophilic stage and reduce the processing time. Powdered sawdust, wood shavings, wood chips, prunings waste and straw were used as bulking agents and the thermophilic stage temperature profile was used as the main indicator for gauging if the composting process was developing correctly. Our results showed that a 12 h(-1) turning frequency and an oxygen concentration of 10% were the optimal conditions for the composting process to develop.

Effect of GnRH agonist and hCG treatment on VEGF, angiopoietin-2, and VE-cadherin: trying to explain the link to ovarian hyperstimulation syndrome.

This study evaluated the differentially modulated expression of vascular mediators in oocyte donors after hCG vs. GnRHa triggering, trying to understand ovarian hyperstimulation syndrome pathophysiology. Donors who received GnRH agonist triggering showed a statistically significant decrease in vascular endothelial growth factor in follicular fluid and in mRNA expression in granulosa cells, with no differences in angiopoietin 2 and vascular endothelial cadherin levels in serum or follicular fluid.

Low-dose human chorionic gonadotropin versus estradiol/progesterone luteal phase support in gonadotropin-releasing hormone agonist-triggered assisted reproductive technique cycles: understanding a new approach.

It remains unclear how GnRH agonist (GnRHa) triggering affects the luteal phase, so we investigated the luteal phase after GnRHa triggering, supported with conventional E(2)/P with or without low-dose hCG. E(2)/P support, compared with low-dose hCG, induced a shorter luteal phase (11.2 ± 1.

Differential regulation of VEGF after final oocyte maturation with GnRH agonist versus hCG: a rationale for OHSS reduction.

In a prospective cohort study, we compared the effect of hCG and GnRH agonist triggering of final oocyte maturation on vascular endothelial growth factor production. Vascular endothelial growth factor follicular fluid concentration was significantly lower in response to GnRH agonist versus hCG, which may partially explain the absence of OHSS in these of women.
