Studying Human Fertility [PDF]

Environmental Health Perspectives, 2004
We very much welcome the National Children’s Study, which promises to raise the study of factors affecting reproduction and development to a new level. An impressive and exciting range of new methodologies is being developed (Chapin and Buck 2004; National Children’s Study 2004).

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]

, 2006
Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

Human sperm ion channel (dys)function:implications for fertilization [PDF]

, 2019
BACKGROUND: Intensive research on sperm ion channels has identified members of several ion channel families in both mouse and human sperm. Gene knock-out studies have unequivocally demonstrated the importance of the calcium and potassium conductances in ...

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?

Derivation of HVR1, HVR2 and HVR3 human embryonic stem cell lines from IVF embryos after preimplantation genetic diagnosis (PGD) for monogenic disorder [PDF]

, 2016
From 106 human blastocyts donate for research after in vitro fertilization (IVF) and preimplantation genetic diagnosis (PGD) for monogenetic disorder, 3 human embryonic stem cells (hESCs) HVR1, HVR2 and HVR3 were successfully derived.

Involvement of sperm acetylated histones and the nuclear isoform of Glutathione peroxidase 4 in fertilization [PDF]

, 2017
We previously demonstrated that the nuclear form of Glutathione peroxidase 4 (nGPx4) has a peculiar distribution in sperm head, being localized to nuclear matrix and acrosome and that sperm lacking nGPx4 are more prone to decondensation in vitro. In this

DISEASE DIVERSITY AND HUMAN FERTILITY [PDF]

Evolution, 2001
The existence of parasitic constraints on the evolution of life-history traits in free-living organisms has been demonstrated in several plant and animal species. However, the association between different diseases and human traits is virtually unknown.

THE INFLUENCE OF RADIATION ON HUMAN FERTILITY [PDF]

Reproduction, 1968
The number of children born to 180 females exposed to abdominal fluoroscopy in connection with an attack of intussusception in infancy or childhood was compared to the number born to women who were treated for the same disease without fluoroscopy. No difference was found between the number of children born or the age distribution of birth between the ...
