Ali Sami Gurbuz, Ali Cenker
Transvaginal oocyte retrieval is a crucial step in assisted reproductive technology. Various complications may arise during this procedure. Ureteral injury is a rare, but a serious complication in gynecological practice. During oocyte retrieval, ureteral injuries, detachment and obstruction can be seen, though rare. In this study, we will present ureteral obstruction that develops secondary to small hematoma, which mimics ovarian cyst torsion or ruptured ovarian cyst.

PURPOSE: Empty follicle syndrome (EFS) is a complex reproductive disorder characterized by the repeated failure to aspirate oocytes from mature ovarian follicles during in vitro fertilization (IVF). In addition to some cases caused by iatrogenic problems and known genetic factors, there are still many unexplained aspects of EFS. Here, we aimed to assess the clinical and genetic characteristics of two EFS patients. METHODS: We have characterized two primary infertility patients with EFS in a nonconsanguineous family from China...

Pedro Montoya-Botero, Nikolaos P Polyzos
Controlled ovarian hyperstimulation (COH) is a crucial part of assisted reproductive technologies (ART) that resulted in a substantial increase in pregnancy rates from in vitro fertilization (IVF). However, in spite of the apparent benefit of COH on an increase in the number of follicles and the number of oocytes retrieved, allowing for extended embryo culture and enabling the selection of the best quality embryo for transfer, several reports has shown that the supraphysiologic hormonal levels may indeed have a detrimental effect at the endometrial level...

Unexpected poor ovarian response (UPOR) is a problem for both clinicians and infertile couples, because our understanding of this situation is limited. This article investigated incidence of UPOR in women <35 years with normal ovarian reserve function with further analysis.This is a retrospective study, which included 567 women who accepted their first IVF-ET/ICSI. Based on the number of oocytes retrieved, clinic pregnancy rate of fresh cycle, and cycle cancellation rate of fresh cycle, the included cycles were divided into three groups namely unexpected poor ovarian response (UPOR) (n = 120), for which number of oocytes retrieved was not more than 6; normal ovarian response (NOR) (n = 223), for which number of oocytes retrieved was between 7 and 12; and unexpected high ovarian response (UHOR) (n = 224), for which the number of oocytes retrieved was 13 at least...

BACKGROUND: The intra-uterine administration of activated autologous peripheral blood monocytes (PBMC) prior to embryo transfer seems to improve reproductive outcomes in women with repeated implantation failure (RIF). We have previously shown that the intrauterine administration of PBMC treated with corticotropin releasing hormone (CRH) prior to blastocyst transfer (day 5), improves significantly the clinical pregnancy rate of women with RIF. In the present cross-over pilot study, we have investigated whether CRH-PBMC treatment could be of benefit in case of fresh early cleavage stage embryo transfer (day 3) in women with RIF...

The prevalence of poor response to gonadotropin stimulation is approximately 9-24% in women undergoing in vitro fertilization. Interestingly, due to containing a variety of growth factors, platelet-rich plasma (PRP) can play an important role in tissue regeneration and healing. Thus, in this research, we aimed to investigate the intra-ovarian injection of PRP in women with poor ovarian response. To this goal, 23 poor responders constituted the study population, from among whom 19 women were enrolled. These patients underwent ovarian stimulation according to the Shanghai protocol...

INTRODUCTION: In Scandinavian countries, programs for fertility preservation are offered free of charge at tertiary-care university hospitals to all patients facing treatments with risk of subsequent sterility. In this prospective study we aimed to investigate trends in female patients' choices after counseling and fertility preservation outcomes during follow-up in relation to benign vs malignant indications. MATERIAL AND METHODS: Data on 1254 females including 1076 adults and 178 girls who received fertility preservation counseling for either oncologic (N=852) or benign indications (N=402) at Karolinska University Hospital, Stockholm, between 1 Oct 1998 and 1 Dec 2018 were analyzed...

We review here the evolution in the field of embryo aneuploidy testing over the last 20 years, from the analysis of a subset of chromosomes by fluorescence in situ hybridisation (FISH) to the transition toward a more comprehensive analysis of all 24 chromosomes. This current comprehensive aneuploidy testing most commonly employs next-generation sequencing (NGS). We present our experience in over 130,000 embryo biopsies using this technology. The incidence of aneuploidy was lower in trophectoderm biopsies compared to cleavage-stage biopsies...

The aim of the present study was to evaluate the influence of a gonadotropin-releasing hormone (GnRH) antagonist compared with a GnRH agonist on in vitro fertilization (IVF) cycle outcome in reproductive women. The characteristics of treatment and outcomes of pregnancy were retrospectively compared between the antagonist (GnRH-A, antagonist group) and agonist (GnRH-a, agonist group) regimens. The area under the curve (AUC) of receiver operating characteristic (ROC) curves was also used to evaluate whether the endometrial thickness (cm), progesterone (P) level (ng/ml) and estradiol (E2 ) level (pg/ml) on the day of human chorionic gonadotropin (hCG) administration (hCG day) had the ideal sensitivity and specificity for predicting clinical pregnancy...

Controversy exists regarding surgical management of endometriomas in infertile women before in vitro fertilization (IVF) because growing evidence indicates that surgery may impair the ovarian response. The objective of the present systematic review and meta-analysis was to compare surgical and expectant management of endometriomas regarding IVF outcomes. Prospective and retrospective controlled studies were found via the Cochrane Library, Embase, and MEDLINE databases. Thirteen studies (1 randomized controlled trial and 12 observational studies, N = 2878) were pooled, and similar live birth rates were observed in the surgically and expectantly managed groups (odds ratio = 0...

Controlled ovarian stimulation (COS) is used to augment the number of retrieved oocytes in in vitro fertilization (IVF). Follicular fluid (FF) contributes significantly to oocyte quality. Since the FF is composed of follicular secretions and plasma exudation, it reflects alterations in granulosa and thecal cells secretion as well as changes in the level of plasma constituents. Phospholipids (PL) and free fatty acids (FFA) are important constituents of both, FF and serum. Our hypothesis is that COS affects the level of PL and FFA in serum...
