Does Hysteroscopic Dissection of Partial Uterine Septum Represent a Risk Factor for Placental Abnormalities in Subsequent Pregnancy Compared with Con…

2022

Background: Hysteroscopic septum dissection (HSD) is thought to improve fertility and pregnancy outcomes. However, the available literature suggests that uterine surgery can cause placental abnormalities in subsequent pregnancies. Methods: A case–control study was performed at the University Medical Center of Ljubljana, Department of Human Reproduction, from 1 January 2016 to 31 December 2018. The primary outcome was the association between HSD and the occurrence of placental abnormalities. We included women who underwent HSD due to infertility. Age-matched women who underwent hysteroscopic surgery for other issues were considered as controls. In addition, we divided the groups according to…

Chronic Endometritis in Infertile Women: Impact of Untreated Disease, Plasma Cell Count and Antibiotic Therapy on IVF Outcome—A Systematic Review and…

2022

This systematic review and meta-analysis aims to evaluate the impact of chronic endometritis (CE) and its therapy on in vitro fertilization (IVF) outcome. Additionally, we aim to investigate whether various degrees of CE severity may exert a different effect on IVF outcome. Ongoing-pregnancy rate/live-birth-rate (OPR/LBR), clinical-pregnancy rate (CPR), and miscarriage rate (MR) were calculated. A total number of 4145 patients (from ten studies) were included. Women with CE had lower OPR/LBR (OR 1.97, p = 0.02) and CPR (OR 2.28, p = 0.002) compared to those without CE. CE cure increased OPR/LBR (OR 5.33, p < 0.0001) and CPR (OR 3.64, p = 0.0001). IVF outcome was comparable between women …

Inositol supplementation and IVF outcome: preliminary data

2012

Myo-Inositol (MI) is involved in several aspects of human reproduction. Elevated concentrations of myo-inositol in human follicular fluids, in fact, seem to play a positive role in follicular maturity, since to represent a possible marker of good oocyte quality. Nevertheless its positive role in PCOS patients is a consequence of a defect in the insulin signaling (inositol- containing phosphoglycan mediators) pathway that seems to be implicated in the pathogenesis of insulin resistance. The aim of this study was to analyze the effect of myo-inositol supplementation to “standard” therapy in PCOS women and in “poor responders”, submitted to In Vitro Fecundation (IVF) cycles. In particular, we …

Asistētas reproduktīvas tehnoloģijas grūtniecība, tās iznākums mātēm un jaundzimušajiem

2019

Ievads. Pēc PVO datiem, neauglība skar katru 4 pāri reproduktīvā vecumā, līdz ar to asistētās reproduktīvās tehnoloģijas paliek arvien populārākas. Neskatoties uz mākslīgās apaugļošanas iespēju neauglīgam pārim tikt pie bērna, zinātniskajā literatūrā aprakstīta negatīva superovulācijas ietekme uz sievietes organismu, palielinot komplikāciju attistīšanās risku, kas varētu ietekmēt sievietes un jaundzimušā veselības stāvokli. Darba mērķis. Izpētīt grūtniecības un perinatālo komplikāciju iestāšanās biežumu, superovulācijas ietekmi uz grūtniecības iznākumu, kā arī salīdzināt jaundzimušā parametrus mākslīgās apaugļošanas un spontānas grūtniecības grupās. Materiāli un metodes. Prospektīvs, salīdz…

2-feniletanola biosintēze ar raugu Kluyveromyces lactis laktozi saturošos substrātos

2018

Fermentācijas procesā raugi spēj sintezēt aromātiskus savienojumus, tāpēc fermentācija ar raugiem ir alternatīva metode dabīgā 2-feniletanola iegūšanai. Darba mērķis bija izpētīt rauga Kluyveromyces lactis izmantošanas iespējas 2-feniletanola biosintēzē laktozi saturošos substrātos. Darbā tika noteikts piemērotākais K. lactis celms 2-feniletanola biosintēzei, tika izpētīta barotnes sastāva ietekme uz 2-PE producēšanu, 2-PE sintēzes dinamika fermentācijas laikā, K. lactis DSM 70799 2-feniletanola tolerance, kā arī tika veikta divfāžu ekstraktīvā fermentācija ar rapšu eļļu. Darbā tika aplūkoti trīs rūpniecībā izmantojami K. lactis celmi, no kuriem K. lactis DSM 70799 uzrādīja augstāko 2-fenil…

P–410 Comparison of the incidence of miscarriage rates in frozen versus fresh embryo transfers in IVF/ICSI cycles: a meta-analysis of Randomized Cont…

2021

Abstract Study question Is the incidence of miscarriage rates increased in frozen embryo transfer (ET) compared with fresh ET? Summary answer The frozen ET is not associated with an increased risk of miscarriage in comparison with fresh ET. What is known already Nowadays, the freeze-all policy has gained great popularity because it minimizes OHSS and it seems to improve the reproductive outcomes. This increase was possible thanks to progress in vitrification procedures. Nevertheless, some recent evidence suggests more caution on the wide use of elective frozen ET in a general IVF population for its possible effect on some pregnancy-related complications. Endometrial preparation schemes for …

P–409 Comparison of the incidence of ectopic pregnancies in fresh versus frozen embryo transfers in IVF/ICSI cycles: a meta-analysis of Randomized Co…

2021

Abstract Study question Is the incidence of ectopic pregnancy (EP) increased in fresh compared with frozen embryo transfer (ET)? Summary answer The fresh ET is not associated with an increase of the incidence of EP in comparison with frozen ET. What is known already EP represents the first cause of mortality in the first trimester of pregnancy. Assisted reproductive technologies (ART) are associated with an increased EP risk. The reasons of this effect are inadequately explained and may be associated with variables patients-related as tubal diseases and ART-related as the number of embryos transferred, the depth of insertion of the catheter tip during ET and the supraphysiological estradiol…

Fertility After Ovarian Cystectomy: How Does Surgery Affect IVF/ICSI Outcomes?

2019

Abstract Introduction For patients considering undergoing assisted reproductive techniques (ART), many concerns arise when persistent ovarian cysts are found. This large study aimed to determine how ovarian cyst removal affects success rates of IVF/ICSI therapies. Methods 550 patients who underwent an IVF/ICSI treatment between 2002 and 2011 with a persistent ovarian cyst ≤ 5 cm before treatment were analyzed retrospectively. 328 patientsʼ preference was to undergo a laparoscopic cystectomy and 222 patients opted for a conservative management. Control subjects included 13 552 patients undergoing IVF/ICSI at the same period of time without an ovarian cyst. Results After adjusting for age, pa…

Prevention of OHSS: Current strategies and new insights

2010

Abstract Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life threatening condition that affects young healthy patients. Many strategies have been proposed to prevent this syndrome. However, to avoid OHSS without compromising on IVF outcome is still a challenge. The most important action is to identify patients at risk even before ovarian stimulation is initiated and to give them special attention. Coasting is the most popular method to avoid/minimize OHSS. Cycle cancellation, cryopreservation, GnRH antagonists, GnRH agonists, i.v. albumin are other strategies that can provide some kind of benefit but do not completely avoid both early and late forms of OHSS and/or…
