The zona pellucida (ZP) is an extracellular matrix universally surrounding mammalian eggs, which is essential for oogenesis, fertilization, and pre-implantation embryo development. Here, we identified two novel heritable mutations of ZP2 and ZP3, both occurring in an infertile female patient with ZP-abnormal eggs. Mouse models with the same mutations were generated by CRISPR/Cas9 gene editing system, and oocytes obtained from female mice with either single heterozygous mutation showed approximately half of the normal ZP thickness compared to wild-type oocytes...

BACKGROUND: The complex relationship between oocyte morphology, specific follicular fluid metabolites, gene expression in cumulus granulosa cells, and oocyte competence toward fertilization and embryo development still needs further clarification. METHODS: Forty-six oocytes retrieved from the largest pre-ovulatory follicle of patients undergoing intra-cytoplasmic sperm injection (ICSI) were considered assessing: (a) oocyte morphological characteristics at polarized light microscopy (PLM), (b) specific follicular fluid (FF) metabolites previously suggested to influence oocyte competence (AMH, markers of redox status and of cytotoxicity), (c) transcription of AMH and AMH type II receptor genes in cumulus cells...

INTRODUCTION: The use of GnRH agonist (GnRHa) for final oocyte maturation trigger in oocyte donation and elective frozen embryo transfer cycles is well established due to lower ovarian hyperstimulation syndrome (OHSS) rates as compared to hCG trigger. A recent Cochrane meta-analysis concluded that GnRHa trigger was associated with reduced live birth rates (LBRs) in fresh autologous IVF cycles compared to hCG trigger. However, the evidence is not unequivocal, and recent trials have found encouraging reproductive outcomes among couples undergoing GnRHa trigger and individualized luteal LH activity support...

The use of intra-cytoplasmic sperm injection (ICSI) has increased significantly worldwide, often chosen instead of in vitro fertilization (IVF), yet long-term health outcomes are unknown and health differences between ICSI and IVF conceptions have not been comprehensively assessed. A systematic review of health outcomes of ICSI-conceived offspring beyond the neonatal period compared to IVF-conceived offspring was carried out. PubMed, OVID Medline/Embase, Informit, Web of Science and Proquest databases were searched on 9 November 2016 for studies reporting on health outcomes in ICSI-conceived offspring beyond 28 days after birth...

BACKGROUND: The expression of the 5,10-methylentetrahydrofolate reductase (MTHFR) gene in human oocytes and preimplantation embryos suggests that the MTHFR gene is involved in folliculogenesis and female reproduction. Considering the importance of the MTHFR gene on female reproduction, the aim of this study was to evalu- ate the influence of MTHFR C677T polymorphism on ovarian marker reserve, particularly serum anti-Müllerian hormone (AMH) levels, and ovarian response as well as clinical pregnancy rates after in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI)...

OBJECTIVE: Intracytoplasmic sperm injection (ICSI) is commonly used during pre-implantation genetic diagnosis (PGD) in vitro fertilization (IVF), aiming to eliminate the risk of contamination from extraneous sperm DNA. Recently, ICSI "overuse" in non-male infertility has been doubted, since it does not offer an advantage over IVF. Prompted by the aforementioned observations, we sought to assess the accuracy of IVF vs ICSI in PGD cases, as might be reflected by a difference in the prevalence of discarded embryos as a consequent of parental contamination...

Ovarian ectopic pregnancy is a rare event in both natural and assisted human reproduction settings. There are few reports of this event after in vitro fertilization. Diagnosis can be challenging, since it requires specific medical expertise. Patients with this condition call for careful management during treatment so as to not affect their fertility potential. This paper describes the case of a woman submitted to ICSI and embryo transfer who subsequently had an ovarian ectopic pregnancy and underwent a laparoscopic partial right oophorectomy...
