ABSTRACT

STUDY QUESTION: What is good practice in ultrasound (US), and more specifically during the different stages of transvaginal oocyte retrieval, based on evidence in the literature and expert opinion on US practice in ART? SUMMARY ANSWER: This document provides good practice recommendations covering technical aspects of US-guided transvaginal oocyte retrieval (oocyte pick up: OPU) formulated by a group of experts after considering the published data, and including the preparatory stage of OPU, the actual procedure and post-procedure care. WHAT IS KNOWN ALREADY: US-guided transvaginal OPU is a widely performed procedure, but standards for best practice are not available. STUDY DESIGN SIZE DURATION: A working group (WG) collaborated on writing recommendations on the practical aspects of transvaginal OPU. A literature search for evidence of the key aspects of the procedure was carried out. Selected papers (n = 190) relevant to the topic were analyzed by the WG. PARTICIPANTS/MATERIALS SETTING METHODS: The WG members considered the following key points in the papers: whether US practice standards were explained; to what extent the OPU technique was described and whether complications or incidents and how to prevent such events were reported. In the end, only 108 papers could be used to support the recommendations in this document, which focused on transvaginal OPU. Laparoscopic OPU, transabdominal OPU and OPU for IVM were outside the scope of the study. MAIN RESULTS AND THE ROLE OF CHANCE: There was a scarcity of studies on the actual procedural OPU technique. The document presents general recommendations for transvaginal OPU, and specific recommendations for its different stages, including prior to, during and after the procedure. Most evidence focussed on comparing different equipment (needles) and on complications and risks, including the risk of infection. For these topics, the recommendations were largely based on the results of the studies. Recommendations are provided on equipment and materials, possible risks and complications, audit and training. One of the major research gaps was training and competence. This paper has also outlined a list of research priorities (including clarification on the value or full blood count, antibiotic prophylaxis and flushing, and the need for training and proficiency). LIMITATIONS REASONS FOR CAUTION: The recommendations of this paper were mostly based on clinical expertise, as at present, only a few clinical trials have focused on the oocyte retrieval techniques, and almost all available data are observational. In addition, studies focusing on OPU were heterogeneous with significant difference in techniques used, which made drafting conclusions and recommendations based on these studies even more challenging. WIDER IMPLICATIONS OF THE FINDINGS: These recommendations complement previous guidelines on the management of good laboratory practice in ART. Some useful troubleshooting/checklist recommendations are given for easy implementation in clinical practice. These recommendations aim to contribute to the standardization of a rather common procedure that is still performed with great heterogeneity. STUDY FUNDING/COMPETING INTERESTS: The meetings of the WG were funded by ESHRE. The other authors declare that they have no conflict of interest. TRIAL REGISTRATION NUMBER: NA.ESHRE Pages content is not externally peer reviewed. The manuscript has been approved by the Executive Committee of ESHRE.

ABSTRACT

Mankind has been expressing the breeding topic for thousands of years. Reproduction is the primary instinct of human beings and it is a social, cultural, medical issue. Demographic infertility is one of them, which is defined infertility as the inability to become pregnant with a live birth, within five years of regular sexual contact based upon a consistent union status in marriage maintaining a desire for a child with the lack of contraceptive use and non-lactating. A first mentions about infertility and surrogacy is discovered on a 4000-year-old clay tablet of marriage contract belonging to the Assyrian period exhibited at Istanbul Archeology Museum in Turkey. In conclusion, there are many different ways to solve infertility problems like surrogacy as mentioned even 4000 years ago in this Assyrian clay tablet of marriage contract as the first time in the literature. Medical treatments in relation to human infertility will continue to be the focus of social and cultural debates. Hence, more legislation and regulation will come in many countries to control the unauthorized exploitation of the patient.

ABSTRACT

PURPOSE: To evaluate the circulatory levels of endothelin 1 (ET-1) and the placental alkaline phosphatase (ALP) in pregnant women with placenta percreta (PP) and a control group. METHODS: This study was carried out in the Obstetrics and Gynecology and in the Biochemistry Departments of Harran University Medical School. Forty-four women who underwent cesarean section (CS) due to PP and 44 women who underwent CS for other obstetric reasons were included in this study. The PP diagnosis was made by a pathologic examination that showed an extreme trophoblastic invasion involving the uterine serosa.The levels of circulating ET-1 and placental ALP were measured by an enzyme-linked immunosorbent assay (ELISA). RESULTS: Women with PP more frequently received antenatal steroids and blood transfusions and they delivered at an earlier gestational age compared to controls. In women with PP, preoperative circulating ET-1 and placental ALP levels were lower than in the controls (p < .05 for both). CONCLUSIONS: The findings suggest that a decrease in ET-1 and placental ALP levels might play a role in the pathogenesis of PP.

ABSTRACT

OBJECTIVE: The purpose of the present study is to analyses the role of apoptotic activity in placental abruption (PA) development by evaluating the level of plasma M30-M65. METHODS: The study group included 46 pregnant women who underwent caesarean sections (CS) because of PA, and the control group included 48 pregnant women who underwent CS because of obstetric causes. Venous blood samples were received from all expectants before starting the CS for the purpose of evaluating the M30-M65 levels, which are indicators of apoptotic activity in maternal plasma. RESULTS: The plasma M30-M65 levels were determined to be statistically significantly higher in with PA group. The sensitivity and specificity of the test were determined to be 71.7% and 64.6%, respectively in identifying the expectants with PA when the cut-off value was taken as 163.50 U/L for the plasma M30 value. The sensitivity and specificity of the test were determined to be 76.1% and 66.7%, respectively in identifying the PA when the cut-off value was taken as 295.50 U/L for the M65 value. CONCLUSIONS: The increase of apoptotic activity induced by thrombin resulting from decidual bleeding may have a role in the development of PA.

ABSTRACT

AIM: Surgical complications were compared between patients with three or less prior cesarean deliveries and four or more prior cesarean deliveries. MATERIALS AND METHODS: Records of 120 patients who had undergone cesarean sections (CSs) in our Department of Obstetrics and Gynecology, between August and November 2015, were retrospectively studied. Cases were reviewed on the basis of age, type of operation, type of anesthesia, number of CSs, time of hospitalization, and intra-operative and post-operative complications. RESULTS: Cesarean sections had been performed on 62 (51.7%) patients whose cesarean number was three or less, while 58 (48.3%) patients had multiple CSs four or more. Patients with four or more prior cesareans had an increased rate of intra-abdominal adhesions, compared with the other group. There was no significant difference in the gestational weeks, neonatal admission rate, incidence of cesarean hysterectomy, uterine scar rupture, placenta previa with placental invasion anomalies, bladder and bowel injuries, incidence of peripartum hemorrhage and blood transfusion rate between the two groups. CONCLUSION: There is no greater risk of maternal complications in patients with four or more prior cesareans, excepting intra-abdominal adhesions.
