On biotechnology, theology, and the human sciences [PDF]

, 2018
There may be very good Christian theological reasons to oppose human biotechnological enhancement. It is, however, difficult to discern what they are. Much of the specifically Christian response to transhumanist biotechnological enhancement has revolved ...

Adaptation of the technology for culturing bovine embryos on commercial media for human embryos [PDF]

BIO Web of Conferences
We have studied the efficiency of using commercial media developed for human-assisted reproductive technologies (ART) for bovine embryos. The dynamics of bovine cells and embryos at the stages of maturation, fertilization, and preimplantation development

RNA-Seq transcriptome reveals different molecular responses during human and mouse oocyte maturation and fertilization

BMC Genomics, 2020
Background Female infertility is a worldwide concern and the etiology of infertility has not been thoroughly demonstrated. Although the mouse is a good model system to perform functional studies, the differences between mouse and human also need to be ...

Depolarization of sperm membrane potential is a common feature of men with subfertility and is associated with low fertilization rate at IVF [PDF]

, 2016
STUDY QUESTION. Are significant abnormalities in outward (K+) conductance and resting membrane potential (Vm) present in the spermatozoa of patients undertaking IVF and ICSI and if so, what is their functional effect on fertilization success?

CD9 Expression by Human Granulosa Cells and Platelets as a Predictor of Fertilization Success during IVF

Obstetrics and Gynecology International, 2010
Objective. To determine whether CD9 expression on human granulosa cells (GCs) and platelets could predict the success of conventional fertilization of human oocytes during in vitro fertilization (IVF). Methods.

#338 : Insights into the Zona-Pellucida Mediated Selection of Fertilization-Competent Spermatozoa

Fertility & Reproduction, 2023
Background and Aims: Human zona pellucida (ZP) selectively interacts with high-quality spermatozoa characterized by superior morphology and normal chromatin structure to achieve fertilization. Human ejaculate contains millions of spermatozoa with varying

Zinc protection of fertilized eggs is an ancient feature of sexual reproduction in animals.

PLoS Biology, 2020
One of the earliest and most prevalent barriers to successful reproduction is polyspermy, or fertilization of an egg by multiple sperm. To prevent these supernumerary fertilizations, eggs have evolved multiple mechanisms.

Expression and potential roles of HLA-G in human spermatogenesis and early embryonic development. [PDF]

PLoS ONE, 2014
As one of the non-classical major histocompatibility complex(MHC)-1 antigens, Human Leukocyte Antigen G (HLA-G), has been suggested as a prognostic marker to identify the embryo developmental potential. In the present study, we investigated the potential
