Abstract
Objective The aim of this study was to describe characteristics and outcomes of assisted reproductive technology (ART) cycles performed in 2019 in Turkey. Material and Methods One-hundred and sixty-five ART centers in Turkey were invited to submit data. The survey was sent to center directors via e-mail with anonymous links by Qualtrics™. The survey involved questions about their patient characteristics, clinical practices, and outcomes. Results Forty-one (24.8%) centers responded to e-mails, and data gathered from 25 centers was included in the analyses. In 25 centers, 18,127 fresh or frozen transfers were carried out during the study period, of which 7796 (43.0%) were fresh and the rest were either frozen (45.2%) or embryo transfers (ET) with preimplantation genetic testing (PGT) (11.8%). The live birth rate per ET was as 30.6%, 40.1%, and 50.7% in fresh, frozen and PGT cycles, respectively. A single embryo was transferred in 65.3% of all transfers and singleton live births comprised 86.1% of all deliveries. For cycles with intrauterine insemination, 1407 were started in 2019, and 195 clinical pregnancies, 150 live births with 19 multiple pregnancies occurred. A total of 1513 ART cycles were initiated for foreign patients. Russia (29.6%), Germany (7.4%), Iraq (4.6%), Uzbekistan (3.1%), and Syria (1.4%) were the top five countries with most patients coming to Turkey for ART. Conclusion The survey results are in parallel with the reports of international institutions and organizations. With repeated editions, the data collected with annual surveys can be used to inform ART practices in the coming years.

Abstract
RESEARCH QUESTION What are the embryonic profiles and oocyte maturation dynamics in patients with tubulin beta eight class VIII (TUBB8) mutations leading to oocyte maturation abnormalities (OMAS), and are pregnancies possible in this population? DESIGN A prospective cohort study was undertaken in a private fertility clinic between January 2019 and December 2022. Whole-exome genomic studies (WES) were performed to detect mutation types. In-vitro maturation (IVM) was compared in 18 subjects: nine with TUBB8 mutations, and nine without TUBB8 mutations to act as the control group. The distributions of oocyte maturation and embryonic development profiles were recorded. IVF and IVM outcomes of the 18 cases were evaluated. The primary outcomes were the embryonic profiles and maturation dynamics of oocytes derived from IVF or IVM in women as related to TUBB8 mutations. RESULTS Mutations were detected in 52 of 89 (58.4%) women who underwent WES analysis. Twelve TUBB8 mutations were detected in nine women (10.1%) with OMAS. Seven novel TUBB8 mutations were noted. Two pregnancies were obtained in women with c.535 G>A TUBB8 mutations. When comparing IVM outcomes between women with and without TUBB8 mutations, there were no differences in oocyte, embryo or pregnancy parameters (P>0.05 in all cases). CONCLUSIONS It is clear that further TUBB8 mutations which cause oocyte or embryonic arrest will be detected in future. Although biochemical or ectopic pregnancies may be possible in some of these women, no live births or ongoing pregnancies have been reported to date.

Abstract
A small proportion of infertile women experience repeated oocyte maturation abnormalities (OMAS). OMAS include degenerated and dysmorphic oocytes, empty follicle syndrome, oocyte maturation arrest (OMA), resistant ovary syndrome and maturation defects due to primary ovarian insufficiency. Genetic factors play an important role in OMAS but still need specifications. This review documents the spectrum of OMAS and to evaluate the multiple subtypes classified as OMAS. In this review, readers will be able to understand the oocyte maturation mechanism, gene expression and their regulation that lead to different subtypes of OMAs, and it will discuss the animal and human studies related to OMAS and lastly the treatment options for OMAs. Literature searches using PubMed, MEDLINE, Embase, National Institute for Health and Care Excellence were performed to identify articles written in English focusing on Oocyte Maturation Abnormalities by looking for the following relevant keywords. A search was made with the specified keywords and included books and documents, clinical trials, animal studies, human studies, meta-analysis, randomized controlled trials, reviews, systematic reviews and options written in english. The search detected 3,953 sources published from 1961 to 2021. After title and abstract screening for study type, duplicates and relevancy, 2,914 studies were excluded. The remaining 1,039 records were assessed for eligibility by full-text reading and 886 records were then excluded. Two hundred and twenty seven full-text articles and 0 book chapters from the database were selected for inclusion. Overall, 227 articles, one unpublished and one abstract paper were included in this final review. In this review study, OMAS were classified and extensively evaluatedand possible treatment options under the light of current information, present literature and ongoing studies. Either genetic studies or in vitro maturation studies that will be handled in the future will lead more informations to be reached and may make it possible to obtain pregnancies.

Abstract
In this study, we aimed to determine whether human embryos secrete interleukin-1β (IL-1β) into culture media and its correlation with embryo grade and development. Culture media supernatants of 100 embryos obtained from 39 cycles of 38 patients and cultivated individually were collected 2 and 3 days after intracytoplasmic sperm injection (ICSI). IL-1β concentrations of samples were determined with ELISA and compared with embryo grades and blastomere numbers. Embryo grades and the amount of IL-1β they secreted were found not to be correlated (p:0.559). Numbers of blastomeres each embryo had at 2nd and 3rd days were found to be correlated with IL-1β secreted (p:0.00 and p:0.00, respectively). Mean amount of IL-1β secreted by the embryos from ejaculated sperm cycles were found to be significantly higher than that of embryos from TESE cycles (p:0.016). Patient age and etiology of infertility were not correlated with the amount of IL-1β secreted and embryo grade. In conclusion, preimplantation human embryos secrete IL-1β in their media in amounts correlated with their blastomere numbers.
