#82 : Does Apoptotic Body Impair Pregnancy Outcome

Fertility & Reproduction, 2023
Background: Morphologically suboptimal blastocyst is often associated with poorer pregnancy outcomes. Apoptotic body is one of the abnormal findings in blastocysts characterised by cellular shrinkage and a darker appearance.

Fertility and ageing [PDF]

Human Reproduction Update, 2005
The late 20th century trend to delay birth of the first child until the age at which female fecundity or reproductive capacity is lower has increased the incidence of age-related infertility. The trend and its consequences have also stimulated interest in the possible factors in the female and the male that may contribute to the decline in fecundity ...

Healthy live birth following ICSI with retrograde ejaculated cryopreserved sperm

International Journal of Endorsing Health Science Research, 2019
Background: Retrograde ejaculation is a medical condition that occurs when semen enters the urinary bladder (retrograde) during orgasm instead of passing through the penis (antegrade). Complete retrograde semen flow causes male infertility.

The Race to Equilibrate

Fertility & Reproduction, 2022
Background: While it is well documented that culture in hypoxic conditions produces superior outcomes, the mechanics of establishing such conditions within the embryo’s liquid environment is less clear.

Fertilization 2: Polyspermic Fertilization [PDF]

, 2017
During fertilization in animals, a haploid egg nucleus fuses with a haploid sperm nucleus to restore the diploid genome. In most animals including mammals, echinoderms, and teleostei, the penetration of only one sperm into an egg is ensured at fertilization because the entry of two or more sperm is prevented by polyspermy block systems in these eggs ...

Knockout of the mitoribosome rescue factors Ict1 or Mtrfr is viable in zebrafish but not mice: compensatory mechanisms underlying each factor's loss

FEBS Open Bio, EarlyView.
Mitochondria contain two mitoribosome rescue factors, ICT1 and MTRFR (C12orf65). ICT1 also functions as a mitoribosomal protein in mice and humans, and its loss is lethal. Although Mtrfr knockout mice could not be generated, knockout zebrafish lines for ict1 and mtrfr were established.

“Thick and Viscous” or “Light and Easy”: An Oil Overlay Comparison

Fertility & Reproduction, 2022
Background: Oil overlay in IVF culture media is essential in the maintenance of pH and prevention of evaporation. The recent proliferation of “Heavy oil” raises questions of how oil density and viscosity affect CO2 diffusion into and out of culture media.

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

FEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Improving the Accuracy of Constant Temperature Monitoring of Open-Air Stereo Stages

Fertility & Reproduction, 2022
Background: Temperature regulation and monitoring is critical in IVF laboratories. Constant temperature monitoring of open-air stereo stages has proven to be a difficult feat, as probes are exposed to ambient air, making readings irreflective of actual ...
