Nucleic acids delivery methods for genome editing in zygotes and embryos: the old, the new, and the old-new [PDF]

open access: yes, 2016
In the recent years, sequence-specific nucleases such as ZFNs, TALENs, and CRISPR/Cas9 have revolutionzed the fields of animal genome editing and transgenesis.

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

open access: yesAndrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Oncofetal Biology: From Fundamental Mechanisms to Emerging Therapeutic Opportunities

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oncofetal biology provides a transformative framework for understanding cancer initiation, progression, and therapeutic intervention. This review synthesizes the core molecular mechanisms connecting embryonic development and tumorigenesis from a multidisciplinary standpoint and outlines future research trajectories and clinical applications, and we aim

[Intracytoplasmic sperm injection].

open access: yesTidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 1998
The first results of intracytoplasmic sperm injection (ICSI) in Norway are presented. Acceptable fertilization rates were obtained for all indications; severe male infertility, as well as moderately reduced sperm quality where in vitro fertilization (IVF) and embryo transfer had previously failed.

Sperm nuclear DNA damage and altered chromatin structure: effect on fertilization and embryo development [PDF]

open access: yes, 2017
In the first part of this report we investigate whether chromatin anomalies in human spermatozoa can influence fertilization after intracytoplasmic sperm injection (ICSI).
