PURPOSE: To compare reproductive outcomes following conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in poor responders fulfilling the Bologna criteria, with a single oocyte retrieved. METHODS: The pres…

PURPOSE: Several studies have suggested an association between the polymorphisms AhR Arg554Lys, AhRR Pro185Ala, and ARNT Val189Val and endometriosis, but results have been inconclusive. The aim of the present study was to assess these assoc…

PURPOSE: This study aimed to investigate the relationship between the number of oocytes retrieved and clinical outcomes in young women with normal ovarian reserve who were undergoing their first in vitro fertilization and embryo transfer (I…

PURPOSE: A retrospective cohort study was conducted in a single academic center to determine if modified natural cycle in vitro fertilization (mnIVF) is an acceptable treatment for the infertile couple. METHODS: Cycles performed between Ju…

PURPOSE: To investigate the perinatal outcomes of patients with clinical pregnancies from ICSI treatments who had previously undergone hysteroscopic surgery to correct partial intrauterine septa and compare them to outcomes of patients with…

PURPOSE: To study the differences in protein expression profiles of follicular fluid (FF) between controlled ovarian hyperstimulation (COH) and natural ovulatory cycles. METHODS: Twelve infertile women undergoing in vitro fertilization and…

PURPOSE: To establish a ratio of the P level to the number of follicles (P/F ratio) on the day of human chorionic gonadotropin (hCG) administration and to evaluate whether this ratio is associated with in vitro fertilization (IVF) outcome. …

PURPOSE: This study aimed to compare slow freezing (SF) and vitrification (VT) techniques for day 3 embryo cryopreservation in infertile couples. METHODS: This retrospective cohort study enrolled 5613 infertile patients, with 7862 frozen-t…

PURPOSE: The purpose of this study was to determine the association of AZFc subdeletions (gr/gr, b1/b3 and b2/b3) and deletion of DAZ and CDY1 gene copies with male infertility METHODS: Three hundred twelve controls, 172 azoospermic and 34…

PURPOSE: Previous studies have indicated that OxS (oxidative stress) may appear as a possible reason for poor ART outcome. Our aim was to study OxS levels in both partners of couples seeking Assisted reproduction Technology (ART). METHODS:…

PURPOSE: The present study aimed to gather information on the impact of Alpha/European Society of Human Reproduction and Embryology (ESHRE) consensus regarding oocytes with aggregates of smooth endoplasmic reticulum (SERa) on in vitro ferti…

PURPOSE: To determine the factors that affect oocyte extraction efficiency when using the "combined procedure". In the present "combined procedure" ovarian tissue cryopreservation and oocyte extraction from an isolated ovary, later used in …

OBJECTIVE: We assessed the predictive value added by Anti-Mullerian Hormone (AMH) to currently validated live birth (LB) prediction models. METHODS: Based on recent data from our center, we compared the external validity of the Templeton M…

PURPOSE: Polycystic ovarian syndrome (PCOS) is a common cause of female infertility. Factors other than anovulation, such as low embryo quality have been suggested to contribute to the infertility in these women. This 2-year retrospective s…

PURPOSE: To review the current literature regarding the role of vitamin D status in pregnancy outcomes in women undergoing assisted reproductive technology (ART) and to assess cost-effectiveness of routine vitamin D deficiency screening and…

PURPOSE: We performed TaqMan genotyping assays of anti-Mullerian hormone (AMH) and anti-Mullerian hormone receptor type II (AMHRII) single nucleotide polymorphisms (SNPs) in order to investigate how their frequency and distribution affect i…

PURPOSE: To determine whether the measurement of serum AMH can be used to diagnose PCOS and as a tool to predict the prognosis of PCOS. METHODS: This is a case-control study. Women of reproductive age (18-35 years) were recruited consecuti…

BACKGROUND: Recently, a relationship between recurrent pregnancy loss (RPL) and Apolipoprotein E (Apo E) gene polymorphisms has been proposed. In order to investigate the real association between Apo E polymorphisms and RPL, our meta-analys…

PURPOSE: To evaluate basal testosterone (T) levels in women undergoing in vitro fertilization (IVF) cycles and examine the association between basal T levels and ovarian response or IVF pregnancy outcome. METHODS: We retrospectively analyz…

PURPOSE: To investigate the role of genetic variations and expression alterations of BRCA1 and BRCA2 genes in the pathophysiology of endometriosis. METHODS: A genetic association study was conducted in 573 endometriosis cases and 490 contr…

PURPOSE: The Fas-Fas Ligand interaction is one of the essential events for the induction of apoptosis whereas the exact role of their soluble forms in the reproductive system is still not fully understood. Also oxidative stress in the patho…

PURPOSE: To evaluate the efficacy of blastocyst transfer in women with at least two previously unsuccessful in vitro fertilization-embryo transfer (IVF-ET) attempts. METHODS: Retrospective analysis of 238 couples (with previous implantatio…

PURPOSE: According to the latest ART report for Europe, about 13% of pregnancies after frozen embryo transfer are multiple. Our objective was to analyse the impact on the multiple pregnancy rate of two eSFET (elective single frozen embryo t…
